Tilt-Shift Photography Photoshop Tutorial

This tutorial has been produced using Photoshop CS2 on a PC

Step 1: Photo Selection

When choosing a photograph for the tilt-shift effect, bear in mind that you want to give the impression of a miniature model Miniature models are usually viewed from above so try and choose a photo with an elevated viewpoint Buildings, roads, traffic and railways are excellent choices but make sure there is a reasonable wide angle of view

For this tilt-shift photography Photoshop tutorial, we are using a picture of Times Square during

a typical day:

Even before the tilt-shift effect has been applied, it's not too hard to imagine the scene as if it were a model

To find an appropriate image, we suggest you browse through the flickr tilt-shift fakes pool Pay attention to licensing terms though - if you are going to manipulate and display your work it will need to be released under the Creative Commons licence

Step 2 Enter Quick Mask Mode

Open the image in Photoshop and enter Quick Mask Mode by pressing Q on the keyboard, or select the Quick Mask icon as shown in the Tool Palette below:

Step 3 Choose Gradient Tool

Choose the Gradient Tool by pressing G on the keyboard, or select the Gradient Tool icon Be sure to choose the Reflected Gradient option (the fourth icon along before the Mode drop-down)

Step 4 Draw A Line

Draw a vertical line; the start point will be the centre of the in-focus area, and the end will be where the transition from in-focus to out-of-focus is completed This step, and the subsequent two steps, will need a fair degree of trial and error If you look closely at the image below, you will see the line has been drawn from the back door of the silver car up to just under the word Hollywood beneath the street lamp

Once you release the mouse button the area of focus will appear as a red band across the image,

as shown in the next step

Step 5 View Mask Area

Before progressing, review the position of the red mask The middle of the mask is where the in-focus area will be, gradually losing in-focus towards the edges Note the out-of-in-focus effect is yet to

be applied

Step 6 Return To Standard Mode

Press Q on the keyboard to exit Quick Mask Mode and return to Standard Mode, or press the icon on the Tool Palette as shown below The area to apply the focus effect to will be surrounded

by the "marching ants" selection lines:

Step 7 Open Lens Blur Interface

Choose Filter > Blur > Lens Blur:

Step 8 Review Effect And Tweak Settings

Hopefully, you will now see a pleasing focus effect The Photoshop default settings for Lens Blur seem to work well, but experiment with them to improve the effect If you are unhappy with the position of the focus area, go back to Step 4 and try drawing a line in a different place or with

a different centre of focus

Step 9 Exit Lens Blur Interface

Assuming you were happy with the image preview in Step 8, click OK to accept the settings:

Step 10 Remove Selection Boundary

Press CTRL-D on the keyboard to remove the "marching ants" selection bounday:

Step 11 Open Hue/Saturation Adjustment Interface

You may want to boost the colour saturation, to improve the effect Remember that model scenery is often brightly painted so enhancing the saturation helps trick the eye Press CTRL-U

on the keyboard or select Image > Adjustments > Hue/Saturation:

Step 12 Boost Saturation

In this example, we boost the Master saturation to +40

Step 13 Open Curves Adjustment Interface

It may help to increase the contrast of the image slightly using the Curves adjustment Press CTRL-M on the keyboard or select Image > Adjustments > Curves:

Step 14 Adjust Curves

In this example we use a very small S-shaped curve to increase contrast Take care not to over-do this step; in fact, it may not be necessary at all

Step 15 Finished

Here's the finished image
