How to Edit a Photo with Adobe Photoshop

By Contributing Writer

In this article you'll learn to use Photoshop to perform the most commonly used tasks for editing a photo. This includes sharpening, removing red eye, removing blemishes and cropping. This tutorial uses Adobe Photoshop 7.0 on a Windows PC. All versions use similar, but slightly different methods.

Things You'll Need

  • Adobe Photoshop 7.0

Step 1

Open the image to be edited in Photoshop by clicking on File>Open. Browse to the directory where you have the picture and select it.

Step 2

This photo has been zoomed in using the Photoshop navigator window to show the jewels on the crown. When you edit a photo in Photoshop, the little red box in the navigator window shows what part of the photo you're editing. You can click on that red box to grab it and move it to any part of the photo.

Step 3

To sharpen a photo, click on Filter>Sharpen>Sharpen. If the photo is very blurry, choose Filter>Sharpen>Sharpen More for a stronger effect. Repeat this step as needed. You can see that the edited image on the right is sharper than the original on the left.

Step 1

To remove red eye from a photo, first zoom in using the navigator window until the eyes can be seen clearly.

Step 2

Use the elliptical marquee tool to make a round selection around the pupil of one eye. You will see a moving dotted line around the selection.

Step 3

Once the pupil is selected, go to Image>Adjustments/Hue/Saturation. In the Hue/Saturation window, move the saturation scroll bar all the way to the left. It will read "-100." Then move the Lightness scroll bar to a low enough number that the pupil appears black and click OK. Repeat Steps 2 and 3 for the other eye.

Step 1

To remove a blemish from skin, use the clone stamp tool located on the toolbar.

Step 2

Place the cursor over a nearby area of skin and hold the alt key while you left click. Be sure to choose a patch of skin that is similar in both color and shade.

Step 3

Once you have selected the area of skin that you'll use to replace the blemish, mouse over to the blemish and hold the left mouse button down, moving the mouse slowly until the blemish is completely replaced.

Step 1

The most common and simplest Photoshop edit is the crop function. Select the crop tool on the toolbar, start in the top left corner that you want to keep, then click and drag to the bottom right corner of the area you want to keep.

Step 2

If your selection is too large or too small, simply click and drag any part of the selection to make it bigger or smaller.

Step 3

Once you have exactly the part you want to keep selected, hit the Enter key. If there are still areas showing that you don't want, repeat Steps 1 through 3.
