Understanding Navigation

and Measurement Systems

Introduction

When you go on a road trip, you need two things to make

the trip a success: good navigational aids (maps), and an

understanding of how to measure distances between two

points on a road map (1 inch typically equals 100 miles)

When you are working with Adobe Photoshop, one of the

keys to making the journey a success is to understand the

navigational and measurement aids available Photoshop lets

you choose a measurement system to fit a specific project

For example, if you're working on images destined for the

Web or a monitor, you'll be using pixels as a measurement

system

Conversely, if you're outputting to paper, or possibly a

4-color press, you'll likely choose inches or picas Selecting

between different measurement systems does not impact the

quality of the final image, only how you measure distance

Trust me on this one; understanding how to measure

dis-tance helps to make the journey an enjoyable experience (I

know from experience)

Having problems squinting at the small details of a

photo-graphic image? Using the Zoom tool is a great way to get

you focused where you need to be Zooming into a specific

section of a document makes touching up the fine details just

that much easier In addition, the Info panel gives you

up-to-date information on the exact position of the cursor inside

the document, as well as detailed color information that can

be indispensable in color-correcting an image

The ability to create text annotations allows you to record

document information that might be vital to the processing

of the image and pass it on to anyone who opens the

docu-ment Photoshop's navigation and measurement systems are

more than just information; they represent control of the

Photoshop's Navigator panel gives you an overall view of the image and the ability to navigate through the document or change the zoom size Viewing images at different sizes gives you the ability to focus on small elements of the design without actually changing the image in any way Once small areas of an image are enlarged, it's easier for you

to make minute changes Zoom size determines the visible size of an image; the zoom percentage can be seen in the document window

Zooming in (enlarging the image) by using the handy magnifying glass lets you work on and manipulate fine details, and then you can zoom out (reduce the image) to view how the changes impact the entire image The Navigator panel contains a thumbnail view of the image, and under the thumbnail are easy-to-use controls that let you adjust the zoom of the image In addition, changes made in the Navigator panel are immediately viewable in the active document window (what you see is what you get)

Did You Know?

There are additional ways to zoom in

using the Navigator panel In the View

box, hold down the Ctrl key, and then

drag to resize the active document

You can constrain the view box to

drag horizontally or vertically Hold

down the Shift key, and then drag the

view box horizontally or vertically

Navigator Panel Shortcut

You can control the view of the document through a great shortcut

Simply click once in the Zoom input box on the Navigator panel, and then use the Up/Down arrow keys to increase or decrease the zoom value of the document 1% at a time Not fast enough for you? Then hold down the Shift key, and use the Up/Down arrow keys to change the zoom size 10% at a time Press the Enter key to see your changes reflected in the active document window

For Your Information

Zoomed images are typically larger than the size of the document win-dow When this happens, Photoshop adds navigational scroll bars to the bottom and the right of the document window However, using scroll bars is not the only way to change your position within the image;

the Navigator panel gives you a visible approach to changing the view-able area of the image The view box in the Navigator panel represents the visible boundaries of the active document window, which is the viewable area of the image

You can show the Navigator panel If

the Navigator panel is not visible, click

the Window menu, and then click

Navigator

You can change the Zoom size of an

image using the Navigator thumbnail

Hold down the Ctrl key (Win) or the A

key (Mac), and then drag in the

thumb-nail When you release your mouse,

the selected area expands It's just like

using the Zoom tool, except you're

dragging in the Navigator's thumbnail

Conversely, if you drag a second time

(this time using a larger rectangle), the

image zooms out

The colored box in the Navigator panel (proxy preview area) defines the viewable area of the image It's important for the colored lines of the view box to stand out clearly against the image The default color of the view box is a light red; however, some documents contain images that are predominantly the same color as the colored lines of the view-able area, making the viewing area difficult to identify By changing the color of the lines, you can make sure they stand out against the image

This may seem like a small thing, but choosing a color that contrasts with my image significantly cuts down on my frustration level when I'm attempting to identify the viewable area

In Photoshop, the Screen Display mode determines the background displayed behind the active image For example, you can choose a Screen Mode that changes the background to black, and then hides all the panels Since monitor backgrounds, combined with Photoshop's panels, add distracting colors to your workspace, changing the Screen Mode gives you a chance to isolate your image against a solid color background Viewing your images against a black or gray background helps your eyes identify the true colors within an image

Working with the Zoom tool gives you one more way to control exactly what you see in Photoshop Just like the Navigator panel, the Zoom tool does not change the active image, but allows you to view the image at different magnifications The Zoom tool is located towards the bottom

of Photoshop's toolbox, and resembles a magnifying glass The maxi-mum magnification of a Photoshop document is 1600%, and the mini-mum size is 1 pixel Increasing the magnification of an image gives you control over what you see and gives you control over how you work

Large documents are difficult to work with and difficult to view Many large documents, when viewed at 100%, are larger than the maximum size of the document window, requiring you to reduce the zoom in order

to view the entire image

Changing the View

with the Zoom Tool

Zoom In the View of an Image

Select the Zoom tool on the

toolbox

Use one of the following methods:

◆ Click on the document.

The image increases in

magnification centered

on where you clicked

◆ Drag to define an area with the

Zoom tool.

The image increases in

magnification based on the

boundaries of the area you

dragged When you zoom in to

500% or more magnification, a

Pixel Grid will appear, making it

easy to make pixel-specific

modifications

◆ Bird's Eye View.

If you are zoomed into an

image, you can press and hold

the H key, click with your

mouse and zoom out Then

reposition the viewing

rectangle to the next spot you

want to zoom into and it will

zoom you into that specific

spot

Zoom in Click and drag method

Zoom Out the View of an Image

Select the Zoom tool on the

toolbox

Hold down the Alt (Win) or Option

(Mac) key, and then click on the

screen to reduce the zoom of the

active document

The zoom reduction centers on

where you click on the active

document

IMPORTANT Since images

viewed in Photoshop are

composed of pixels (like bricks in a

wall), the only way to really see

what the printed results of your

artwork will look like is to view the

image (even if it is too big for the

screen) at 100%

Zoom out

Did You Know?

You can zoom in or out using shortcut

keys regardless of what tool you’re

currently using To zoom in, press

Ctrl+Spacebar (Win) or A+Spacebar

(Mac) and click or drag to define an

area To zoom out, press

Ctrl+Space-bar+Alt (Win) or A+Spacebar+Option

(Mac) and click or drag to define an

area

You can always display a clear view.

When you zoomed into your image at

33% or 66% in previous versions of

Photoshop, you would get a jaggy

pre-view Now, no matter what

magnifica-tion size you choose, the preview is

crisp and clear
