SECTION 1
Lesson 1.3: Working With Colour Brightness and Contrast

   

 

 

In this exercise you will use the Shadow/Highlight dialog, the Brightness/Contrast dialog, and the Hue/Saturation dialog to retouch the Island girl image from the Photoshop CS samples folder.

 

1.

To begin, start Photoshop CS by double clicking the desktop icon, or by clicking Start -> Programs->Adobe Photoshop CS from the start menu.

 

 

2.

When Photoshop CS opens, press the Shift + Ctrl + O keys to open the File Browser. Alternatively, you can choose File->Browse from the menu bar.

 

 

Using the file browser, navigate to the Photoshop CS samples folder, and double click on the Island Girl thumbnail to open the image.

 

 

3.

When the image opens, right click on the document window title bar and click the Duplicate option from the pop up menu. Alternatively, click Image followed by Duplicate, from the menu bar to create a copy of the image. Name your copy Practice3 in the Duplicate Image Dialog box. Once your copy is open along with the original, close (X) the file browser.

 

Adjust the document window sizes by dragging on the document window borders, and adjust their positions by dragging them by their title bars until the images are side by side.

 

 

 

4.

Make sure the copy is the active image, and click Image from the menu bar followed by Adjustments and then Shadow/Highlights.

 

When you see the Dialog box, place a check in the Show More Options checkbox to display the full array of options.

 

 

In the dialog box, set the Shadows Amount to 62%, the tonal width to 50%, and the Radius to 54px.

 

Set the Highlights Amount to 14%, The Tonal Width to 38%, and the Radius to 50px.

 

Set the Colour Correction to +34, and the Midtone Contrast to +2.

 

When you are finished, click the OK button, and your Photoshop screen should look something like this.

 

 

5.

Next, choose Image->Adjustments->Hue/Saturation from the menu bar to display the Hue/Saturation dialog box.

 

 

Select the Reds from the Edit drop list, and set the Saturation to +24. This will make the reds in the image more vivid.

 

 

 

 

6.

Although the image may look better than the original in many ways, remember that currently we are working with the image at only around 25% to 35% zoom. If you zoom the image to 100%, you may find the results of your image edits less pleasing.

 

Make sure the working copy is active, and enter 100 in the zoom field at the lower left of the status bar and press Enter.

 

Next, make the original image active, and enter 100% for a zoom value in the status bar.

 

Resize and move the document windows until the original and the copy are side by side.

 

Use the scroll bars in your image windows to display the images as shown below.

 

Looking at your Photoshop CS screen, which image do you think looks better?

 

 

7.

Next, choose Image->Adjustments->Brightness/Contrast from the menu bar.

 

In the resulting dialog box, make slight Brightness and Contrast adjustments using the sliders while watching the image.

 

 

Judge what brightness and contrast settings are best by how the image looks to you. If you think the image looks best without these adjustments, click Reset (Alt + cancel button) to reset the values to zero. If you want to keep the adjustments you make click the OK button.

 

 

8.

Next, set the zoom value for both the copy and the original image to about 30%. You can enter the values directly into the status bar while the given image is active, or you can select the Zoom tool from the toolbox, and press the Alt key while clicking on the image to zoom out. If your mouse has a wheel button, you can hold the Alt key which will allow you to zoom in and out with your wheel.

 

 

Here are the images zoomed out to about 33 %.

 

 

9.

Close (X) the original image by clicking the close button in the upper right of the image window.

 

Click File from the menu bar followed by Save As to invoke the save as dialog. Save the image in your practice folder as Practice3. Save it as a JPEG formatted image.

 

 

10.

If the JPEG Options dialog box appears, set the image quality to Maximum by selecting this option from the Quality drop list.

 

When you are ready, click the OK button.

 

 

11.

After you save your image, close Photoshop CS (Ctrl + Q).
