File formats represent different ways to save a file to disk Some formats provide

unique image-compression schemes, which save an image in a manner that consumes

less space on disk Other formats enable Photoshop to trade images with different

applications running under Windows or some other platform

The native format

Like most programs, Photoshop offers its own native format — that is, a format

optimized for Photoshop’s particular capabilities and functions This psd format

saves every attribute that you can apply in Photoshop — including layers, extra

channels, file info, and so on — and is compatible with Versions 3 and later of the

program Of course, when you open files in earlier versions of Photoshop, you

lose file attributes related to Version 6 features, such as annotations, color proof

options, and so on

Perhaps not surprisingly, Photoshop can open and save more quickly in its native

format than in any other format The native format also offers image compression

Like TIFF’s compression, the Photoshop compression scheme does not result in any

loss of data But Photoshop can compress and decompress its native format much

more quickly than TIFF, and the compression scheme is better able to minimize the

size of mask channels (as explained in Chapter 9)

The downside of the Photoshop format is that relatively few applications other

than Photoshop support it, and those that do don’t always do a great job Some

applications such as CorelPhoto-Paint and Adobe After Effects can open a layered

Photoshop image and interpret each layer independently But most of the others

limit their support to flat Photoshop files To accommodate these programs, you

can either (1) deselect the Layers check box in the Save dialog box to save a

flat-tened version of the image or (2) activate the Maximize Backward Compatibility

check box in the Preferences dialog box

However, I intensely dislike both of these options (In fact, you should be sure

to turn off File Compatibility, for reasons explained in Chapter 2.) The native psd

format was never intended to function as an interapplication standard; it was meant

for Photoshop alone So use it that way If you want to trade a flattened image with

some other program, use TIFF, JPEG, or one of the other universal formats

explained over the course of this chapter

One exception: If you’re creating a grayscale image for use with Filter ➪ Distort ➪

Displace, you have to create a Photoshop 2.0–compatible file The best bet is to

save the image in the Photoshop 2.0 format Otherwise the Displace filter won’t

see the grayscale image I tell you more about this filter in Chapter A on the

CD-ROM that accompanies this book

Special-purpose formats

With 20 file formats to choose from, you can imagine that most are not the kindsyou’ll be using on a regular basis In fact, apart from the native Photoshop format,you’ll probably want to stick with TIFF, JPEG, and GIF for Web images and EPS whenpreparing images for placement into QuarkXPress, PageMaker, and others

Many of the other formats are provided simply so you can open an image created

on another platform, saved from some antiquated paint program, or downloadedfrom the Web In the spirit of sweeping away the chaff so we can move on to thegood stuff, I cover these special-purpose formats first

Notice that I lump Web standards GIF and PNG in with the special-purpose formats.The reason is simple — if you don’t design for the Web, you rarely need them On theother hand, if you do design for the Web, the formats take on special significance,which is why I cover them in depth in Chapter 19

Microsoft Paint’s BMP

BMP (Windows Bitmap) is the native format for Microsoft Paint (included with

Windows) and is supported by a variety of Windows and DOS applications

Photoshop supports BMP images with up to 16 million colors You also can

use RLE (Run-Length Encoding), a lossless compression scheme specifically

applicable to the BMP format

The term lossless refers to compression schemes that conserve space on disk

without sacrificing any data in the image, such as BMP’s RLE and TIFF’s LZW

(Lempel-Ziv-Welch) The only reasons not to use lossless compression are that it

slows down the open and save operations and it may prevent less-sophisticatedapplications from opening an image (Lossy compression routines, such as JPEG,sacrifice a user-defined amount of data to conserve even more disk space, as Iexplain later.)

The most common use for BMP is to create images for use in help files andWindows wallpaper In fact, rolling your own wallpaper is a fun way to show offyour Photoshop skills, which is exactly what I did in Color Plate 3-1 For the bestresults, make sure you set your image to exactly the same pixel dimensions as yourscreen (which you can check from the Settings panel in the Display control panel)

To conserve memory, you may want to reduce the number of colors in your per image to 256 using Image ➪ Mode ➪ Indexed Color Although Color Plate 3-1 maylook quite colorful, I did in fact reduce the palette to a bare-bones 256 colors SeeChapter 19 for the complete lowdown on indexed color

wallpa-When you save the wallpaper image, Photoshop displays the options shown

in Figure 3-8 Generally, you’ll want to select the Windows and Compress (RLE)options, but it really doesn’t matter when creating wallpaper Don’t mess with theDepth options Either you reduced the bit depth using the Indexed Color command

as I directed previously or you didn’t There’s no sense in changing the colors during the save process

Note

To load the wallpaper onto your desktop, right-click anywhere on the desktop and

choose the Properties command This brings up the Display Properties dialog box

shown in Figure 3-9 Click the Browse button and locate your BMP image on disk

Then click the apply button to see how it looks

CompuServe’s GIF

In the old days, the CompuServe online service championed GIF (short for Graphics

Interchange Format) as a means of compressing files so you could quickly transfer

photographs over your modem Like TIFF, GIF uses LZW compression, but unlike

TIFF, GIF is limited to just 256 colors

With the advent of the World Wide Web, the GIF format has grown slightly more

sophisticated Two varieties of GIF currently exist, known by the helpful codes 87a

and 89a GIF87a supports strictly opaque pixels; GIF89a permits some pixels to be

transparent To open either kind of image, choose File ➪ Open

Figure 3-9: You can load a BMP file as desktop wallpaper

using the Display Properties control panel provided with Windows 95 and later

You can save an image with or without transparency by choosing File ➪ Save andselecting CompuServe GIF from the Format pop-up menu When you index (reduce)the image to 256 colors — which you can do either before or during the file saveprocess — select the Transparency check box in the Indexed Color dialog box if you want any areas of the image that are transparent to remain transparent whenyou view the image file in a Web browser Chapter 19 explores this and other issuesrelated to GIF transparency in detail

If you’re resistant to change and want to create GIFs with transparency via the oldExport ➪ GIF89A command, you can; Adobe includes the command as an optionalplug-in on the program CD just for old fogeys like you But you’ll save yourself timeand trouble if you get acquainted with the new method: PC Paintbrush’s PCXPCX doesn’t stand for anything Rather, it’s the extension PC Paintbrush assigns toimages saved in its native file format Although the format is losing favor, many PCXimages are still in use today, largely because PC Paintbrush is the oldest painting

Photoshop 6

program for DOS Photoshop supports PCX images with up to 16 million colors You

can find an enormous amount of art, usually clip art, in this format However, don’t

save files to PCX unless a client specifically demands it Other formats are better

Adobe’s paperless PDF

The Portable Document Format (PDF) is a variation on the PostScript printing

language that enables you to view electronically produced documents on screen

This means you can create a publication in QuarkXPress or PageMaker, export it

to PDF, and distribute it without worrying about color separations, binding, and

other printing costs Using a program called Adobe Acrobat, you can open PDF

doc-uments, zoom in and out of them, and follow hypertext links by clicking highlighted

words Adobe distributes Mac, Windows, and UNIX versions of the Acrobat Reader

for free, so almost anyone with a computer can view your stuff in full, natural color

PDF files come in two flavors: those that contain just a single image and those that

contain multiple pages and images Photoshop can save only single-image PDF files,

but it can open multipage files The program rasterizes both types of files when it

opens them

You open PDF files in different ways depending on what elements of the file you

want to access:

✦ Use File ➪ Open to open a particular page in a multipage PDF file After

select-ing the page you want to view, you can set the image size and resolution of the

rasterized file You also can choose File ➪ Place to add a page as a new layer

to an open image; in this case, you can’t control size and resolution before

adding the page However, you can scale the page after the fact as you can

any layer

✦ Select Import ➪ PDF Image to bring up a dialog box that enables you to open

a particular image in the PDF file

✦ Choose Automate ➪ Multi-Page PDF to PSD to turn each page in the PDF file

into a separate Photoshop image file

The real question, however, is why would you want to open or place a PDF file in

Photoshop instead of viewing it in Acrobat, which provides you with a full range

of document viewing tools not found in Photoshop? Furthermore, because you can

save only single-page PDF files, why on earth would you save to PDF in Photoshop?

I can think of two scenarios where Photoshop’s PDF functions may come in handy:

✦ You want to see how images in a PDF document will look when printed on a

high-resolution printer Open the PDF file using File ➪ Open, set the resolution

to match that of the output device, and eyeball those images on-screen This

“soft-proofing” technique enables you to spot defects that may not be

notice-able in draft proofs that you output on a low-res printer

✦ You need a convenient way to distribute images for approval or input You cansave an image as a PDF file and send it to clients and colleagues, who can viewthe image in Acrobat if they don’t have Photoshop In Photoshop 6, you caneven add text or voice annotations to your PDF file In addition to annotations,Photoshop PDF supports layers, transparency, embedded color profiles, spotcolors, duotones, and more This enables you to route an image for approvalwithout having to flatten the image or otherwise strip it of its Photoshop 6 features Of course, features not supported by Acrobat aren’t accessible tothe viewer.

When you save to PDF in Photoshop, you have a choice of two encoding options.Choose ZIP only for images that feature large expanses of a single color; otherwise,opt for JPEG Keep the Quality option set to Maximum to maintain the best printquality, just as you do for regular JPEG files Select the Include Vector Data andEmbed Fonts check boxes to retain any vector graphics and font data, respectively.Alternatively, you can select the Use Outlines for Text to save text as character out-lines that are editable in the PDF file The final option, Image Interpolation, enablesother programs to interpolate the image when resampling to another size

If you select JPEG encoding, you need a PostScript Level 2 or later printer to output your PDF file Also be aware that separating files into individual plates can be problematic

Apple’s PICT

PICT (Macintosh Picture) is the Macintosh system software’s native graphics format.

Based on the QuickDraw display language that the system software uses to conveyimages on screen, PICT handles object-oriented artwork and bitmapped imageswith equal aplomb It supports images in any bit depth, size, or resolution PICTeven supports 32-bit images, so you can save a fourth masking channel when working in the RGB mode

PICT is obviously popular with the Macintosh crowd, especially folks who don’tknow much about graphics So if you share a lot of files with Mac-type people, youmay occasionally be asked to supply images in the PICT format If you’re trying tosave an image in a format that your mom can open on her Mac, for example, PICTmay be a better choice than JPEG Heck, you can open PICT files inside a word processor, including everything from SimpleText to Microsoft Word Just be suremom has QuickTime loaded on her machine

When you save a PICT image, Photoshop lets you set the bit depth You shouldalways stick with the default option, which is the highest setting available for theparticular image Don’t mess around with these options; they apply automatic pattern dithering, which is a bad thing

Note

Photoshop 6

On the flip side, you may need to open a PICT file a Mac friend sends you Photoshop

can do this, but one problem may trip you up: On the Mac, you have the option of

saving PICT files with a variety of JPEG compressions supplied by Apple’s QuickTime

Unless you have QuickTime installed on your PC — which you might if you do a lot

of surfing on the Web — you won’t be able to open compressed PICT images

Pixar workstations

Pixar has created some of the most memorable computer-animated movies and

commercials in recent memory Examples include the desk lamps playing with a

beach ball from Luxo, Jr., the run-amok toddler from the Oscar-winning Tin Toy,

and the commercial adventures of a Listerine bottle that boxes gingivitis one day

and swings Tarzan-like through a spearmint forest the next But Pixar really made

the grade with the feature-length Toy Story, which provided Disney with enough

merchandising options to last a lifetime

Pixar works its 3D magic using mondo-expensive workstations Photoshop enables

you to open a still image created on a Pixar machine or to save an image to the Pixar

format so you can integrate it into a 3D rendering The Pixar format supports

gray-scale and RGB images

PNG for the Web

Pronounced ping, the PNG format enables you to save 16 million color images

with-out compression for use on the Web As I write this, neither Netscape Navigator nor

Microsoft Internet Explorer support PNG without the help of a special plug-in But

for those folks who want full-color images without the pesky visual compression

artifacts you get with JPEG, PNG may well be a big player in the future (Of course,

I wrote this same paragraph two years ago, so there’s always the chance PNG will

never gain acceptance.)

PNG was invented for the Web and I’ve never seen anyone use it for a purpose other

than the Web Find more information about PNG in Chapter 19, which covers Web

issues in detail

Scitex image-processors

Some high-end commercial printers use Scitex printing devices to generate color

separations of images and other documents Photoshop can open images digitized

with Scitex scanners and save the edited images to the Scitex CT (Continuous Tone)

format Because you need special hardware to transfer images from the PC to a

Scitex drive, you’ll probably want to consult with your local Scitex service bureau

technician before saving to the CT format The technician may prefer that you

submit images in the native Photoshop, TIFF, or JPEG format The Scitex CT

format supports grayscale, RGB, and CMYK images

Cross-Reference

TrueVision’s TGA

TrueVision’s Targa and NuVista video boards enable you to overlay computer

graphics and animation onto live video The effect is called chroma keying because,

typically, a key color is set aside to let the live video show through TrueVision

designed the TGA (Targa) format to support 32-bit images that include 8-bit alpha

channels capable of displaying the live video Support for TGA is widely mented among professional-level color and video applications on the PC

imple-Interapplication formats

In the name of interapplication harmony, Photoshop supports a few specific formats that permit you to trade files with popular object-oriented programs such as Illustrator and QuarkXPress Every one of these formats is

software-a vsoftware-arisoftware-ation on EPS (Encsoftware-apsulsoftware-ated PostScript), which is bsoftware-ased in turn on Adobe’s

industry-standard PostScript printing language You can use Photoshop to editframes from a QuickTime movie created with Adobe Premiere

Rasterizing an Illustrator or FreeHand file

Photoshop supports object-oriented files saved in the EPS format EPS is specificallydesigned to save object-oriented graphics that you intend to print to a PostScriptoutput device Just about every drawing and page-layout program on the planet (and a few on Mars) can save EPS documents

Prior to Version 4, Photoshop could interpret only a small subset of EPS operations

supported by Illustrator (including the native ai format) But then Photoshop 4 came

along and offered a full-blown EPS translation engine, capable of interpreting EPSillustrations created in FreeHand, CorelDraw, Deneba’s Canvas, and more You caneven open EPS drawings that contain imported images, something else Version 3could not do

When you open an EPS or native Illustrator document, Photoshop rasterizes (or renders) the artwork — that is, it converts the artwork from a collection of

objects to a bitmapped image During the open operation, Photoshop presents the Rasterize Generic EPS Format dialog box (see Figure 3-10), which enables you

to specify the size and resolution of the image, just as you can in the New dialogbox Assuming the illustration contains no imported images, you can render it aslarge or as small as you want without any loss of image quality

If the EPS illustration does contain an imported image or two, you need to know theresolution of the images and factor this information into the Rasterize Generic EPSFormat dialog box Select anything but Pixels from both the Width and Height pop-

up menus, and leave the suggested values unchanged Then enter the setting forthe highest-resolution imported image into the Resolution option box (If all theimages are low-res, you may want to double or triple the Resolution value to ensure that the objects render smoothly.)

Tip

Figure 3-10: You can specify the size and resolution at

which Photoshop renders an EPS illustration

You should always select the Anti-aliased check box unless you’re rendering a very

large image — say, 300 ppi or higher Antialiasing blurs pixels to soften the edges of

the objects so they don’t appear jagged When you’re rendering a very large image,

the difference between image and printer resolution is less noticeable, so

antialias-ing is unwarranted

Photoshop renders the illustration to a single layer against a transparent

back-ground Before you can save the rasterized image to a format other than native

Photoshop, you must eliminate the transparency by choosing Layer ➪ Flatten

Image Or save a flattened version of the image to a separate file by choosing

the As a Copy option in the Save dialog box

Rendering an EPS illustration is an extremely useful technique for resolving

print-ing problems If you regularly work in Illustrator or FreeHand, you no doubt have

encountered limitcheck errors, which occur when an illustration is too complex for

an imagesetter or other high-end output device to print If you’re frustrated with

the printer and tired of wasting your evening trying to figure out what’s wrong

(sound familiar?), use Photoshop to render the illustration at 300 ppi and print

it Nine times out of ten, this technique works flawlessly

If Photoshop can’t parse the EPS file — a techy way of saying Photoshop can’t break

down the individual objects — it attempts to open the PICT (Mac) or TIFF (Windows)

preview This exercise is usually futile, but occasionally you may wish to take a quick

look at an illustration to, say, match the placement of elements in an image to those

in the drawing

Placing an EPS illustration

If you want to introduce an EPS graphic into the foreground image rather than to

render it into a new image window of its own, choose File ➪ Place Unlike other File

menu commands, Place supports only EPS illustrations and PDF files

Tip

After you import the EPS graphic, it appears inside a box — which Photoshop calls

a bounding box — with a great big X across it You can move, scale, and rotate the

illustration into position before rasterizing it to pixels Drag a corner handle toresize the image; drag outside the image to rotate it You can also nudge the graphicinto position by pressing the arrow keys When everything is the way you want it,press Enter or double-click inside the box to rasterize the illustration If the place-ment isn’t perfect, not to worry The graphic appears on a separate layer, so youcan move it with complete freedom To cancel the Place operation, press Escapeinstead of Enter

Saving an EPS image

When preparing an image for placement inside a drawing or page-layout documentthat will be printed to a PostScript output device, many artists prefer to save theimage in the EPS format Converting the image to PostScript up front prevents thedrawing or page-layout program from doing the work The result is an image thatprints more quickly and with less chance of problems (Note that an image does

not look any different when saved in EPS The idea that the EPS format somehow

blesses an image with better resolution is pure nonsense.)

A second point in the EPS format’s favor is clipping paths As explained graphically

at the end of Chapter 8, a clipping path defines a free-form boundary around animage When you place the image into an object-oriented program, everything outside the clipping path becomes transparent While some programs — notablyInDesign and PageMaker — recognize clipping paths saved with a TIFF image, many programs acknowledge a clipping path only when saved in the EPS format.Third, although Illustrator has remedied the problems it had importing TIFF images,

it still likes EPS best, especially where screen display is concerned Thanks to theEPS file’s fixed preview, Illustrator can display an EPS image on screen very quicklycompared with other file formats And Illustrator can display an EPS image both inthe preview mode and in the super-fast artwork mode

So if you want to import an image into Illustrator, QuarkXPress, or another oriented program, your best bet is EPS On the downside, EPS is an inefficient for-mat for saving images thanks to the laborious way that it describes pixels An EPSimage may be three to four times larger than the same image saved to the TIFF format with LZW compression But this is the price we pay for reliable printing.Absolutely avoid the EPS format if you plan on printing your final pages to a non-PostScript printer This defeats the entire purpose of EPS, which is meant toavoid printing problems, not cause them When printing without PostScript, useTIFF or JPEG

object-Caution

To save an image in the EPS format, choose Photoshop EPS from the Format pop-up

menu in the Save dialog box After you press Enter, Photoshop displays the dialog

box shown in Figure 3-11 The options in this dialog box work as follows:

✦ Preview: Technically, an EPS document comprises two parts: a pure

PostScript-language description of the graphic for the printer and a bitmapped preview so

you can see the graphic on screen Select the TIFF (8 bits/pixel) option from the

Preview pop-up menu to save a 256-color TIFF preview of the image The 1-bit

option provides a black-and-white preview only, which is useful if you want to

save a little room on disk Select None to include no preview and save even

more disk space

Figure 3-11: When you save an image in the EPS

format, you can specify the type of preview and tack

on some printing attributes

✦ Encoding: If you’re saving an image for import into Illustrator, QuarkXPress,

or some other established program, select the Binary encoding option (also

known as Huffman encoding), which compresses an EPS document by

substi-tuting shorter codes for frequently used characters The letter a, for example,

receives the 3-bit code 010, rather than its standard 8-bit ASCII code, 01100001

(the binary equivalent of what we humans call 97)

Sadly, some programs and printers don’t recognize Huffman encoding, in

which case you must select the less efficient ASCII option ASCII stands for

American Standard Code for Information Interchange, which is fancy jargon for

text-only In other words, you can open and edit an ASCII EPS document in a

word processor, provided you know how to read and write PostScript

Actually, this can be a useful technique if you have a Mac file that won’t open,especially if the file was sent to you electronically Chances are that a Mac-specific header got into the works Open the file in a word processor and

look at the beginning You should see the four characters %!PS Anything

that comes before this line is the Macintosh header Delete the garbage before

%!PS, save the file in text format, and try again to open the file in Photoshop.

The remaining Encoding options are JPEG settings JPEG compression notonly results in smaller files on disk but also degrades the quality of the image.Select JPEG (Maximum Quality) to invoke the least degradation Better yet,avoid the JPEG settings altogether These options work only if you plan toprint your final artwork to a PostScript Level 2 or Level 3 device EarlierPostScript printers do not support EPS artwork with JPEG compression and will choke on the code

So to recap, ASCII results in really big files that work with virtually any printer

or application Binary creates smaller files that work with most mainstreamapplications but may choke some older-model printers And the JPEG settingsare compatible exclusively with Level 2 and later PostScript printers

✦ Include Halftone Screen: Another advantage of EPS over other formats is that

it can retain printing attributes If you specified a custom halftone screenusing the Screens button inside the Page Setup dialog box, you can save thissetting with the EPS document by selecting the Include Halftone Screen checkbox But be careful — you can just as easily ruin your image as help it ReadChapter 18 before you select this check box

✦ Include Transfer Function: As described in Chapter 18, you can change the

brightness and contrast of a printed image using the Transfer button insidethe Page Setup dialog box To save these settings with the EPS document,select the Include Transfer Function check box Again, this option can be dan-gerous when used casually See Chapter 18 for more details

✦ PostScript Color Management: Like JPEG compression, this check box is

com-patible with Level 2 and 3 printers only It embeds a color profile, which helpsthe printer to massage the image during the printing cycle to generate moreaccurate colors Unless you plan on printing to a Level 2 or later device, leavethe option off (For more information about color profiles, read Chapter 16.)

✦ Include Vector Data: Select this option if your file contains vector objects,

including shapes, non-bitmap type, and layer clipping paths Otherwise,Photoshop rasterizes the objects during the save process When you selectthe option, Photoshop displays a warning in the dialog box to remind you that if you reopen the file in Photoshop, you rasterize any vector objects that you saved with the file

✦ Transparent Whites: When saving black-and-white EPS images in Photoshop,

the four check boxes previously discussed drop away, replaced by TransparentWhites Select this option to make all white pixels in the image transparent

6

Photoshop 6

Caution

Tip

Although Photoshop EPS is the only format that offers the Transparent Whitesoption, many programs — including Illustrator and InDesign — treat white pixels in black-and-white TIFF images as transparent as well.

✦ Image Interpolation: Turn on this option if you want another program to be

able to interpolate the image when resampling it to another size For example,suppose you import an EPS image into InDesign and scale it to 400 percent IfImage Interpolation is turned off, then InDesign just makes pixels in the imagefour times larger, as if you had used the nearest neighbor interpolation insidePhotoshop If you turn Image Interpolation on, however, InDesign applies bicubic interpolation in order to generate new pixels (For details on nearestneighbor and bicubic interpolation, see the “General Preferences” section inChapter 2.) Unless you have a reason for doing otherwise, turn this option on

QuarkXPress DCS

Quark developed a variation on the EPS format called Desktop Color Separation

(DCS) When you work in QuarkXPress, PageMaker, and other programs that

support the format, DCS facilitates the printing of color separations Before you

can use DCS, you have to convert your image to the CMYK color space using

Image ➪ Mode ➪ CMYK Color (DCS 2.0 also supports grayscale images with

spot-color channels.) Then bring up the Save dialog box and select Photoshop

DCS 1.0 or 2.0 from the Format pop-up menu

Photoshop 5 introduced support for DCS 2.0 to accommodate images that contain

extra spot-color channels, as explained in Chapter 18 If you add a Pantone channel

to an image, DCS 2.0 is the only PostScript format you can use If your image doesn’t

contain any extra channels beyond the basic four required for CMYK, DCS 1.0 is the

safer and simpler option

After you press Enter, Photoshop displays an additional pop-up menu of DCS options,

which vary depending on whether you’ve selected DCS 1.0 or 2.0, as shown in Figure

3-12 The DCS 1.0 format invariably saves a total of five files: one master document

(which is the file that you import into QuarkXPress) plus one file each for the cyan,

magenta, yellow, and black color channels (which are the files that get printed) The

DCS 2.0 format can be expressed as a single file (tidier) or five separate files (better

compatibility)

Either way, the DCS pop-up menu gives you the option of saving a 72-ppi PostScript

composite of the image inside the master document Independent from the bitmapped

preview — which you specify as usual by selecting a Preview option — the PostScript

composite makes it possible to print a low-resolution version of a DCS image to a

con-sumer-quality printer If you’re using a black-and-white printer, select the 72 pixel/inch

grayscale option; if you’re using a color printer, select the final option Be forewarned,

however, that the composite image significantly increases the size of the master

docu-ment on disk

Notice the two new options at the bottom of the options dialog boxes for DCS 1.0and 2.0: Include Vector Data and Image Interpolation These options work just asdescribed earlier for the Photoshop EPS format

Premiere Filmstrip

Adobe Premiere is a popular QuickTime movie-editing application for both Macsand PCs The program is a wonder when it comes to fades, frame merges, and spe-cial effects, but it offers no frame-by-frame editing capabilities For example, youcan neither draw a mustache on a person in the movie nor can you make brightlycolored brush strokes swirl about in the background — at least, not inside Premiere

You can export the movie to the Filmstrip format, though, which is a file-swapping

option exclusive to Photoshop and Premiere A Filmstrip document organizes

frames in a long vertical strip, as shown on the left side of Figure 3-13 The right

side of the figure shows the movie after I edited each individual frame in ways not

permitted by Premiere A boring movie of a cat stuck in a bag becomes an exciting
