Resize
Depending on your needs, you may want to resize your photo. If you're emailing a picture to a friend, you'll want to resize the picture down to a much smaller size. If you're printing the photo on a greeting card, you can scale down the image to the size of a 4x6 print.
Sharpening the image is the next step in the photo touch up process. Contrary to popular belief, you can't actually sharpen an out of focus image. What I typically do when sharpening an image is to selectively sharpen. That is, I select a part of the image, maybe a person's eyes and sharpen only that area. Leave unimportant areas unsharpened.
Sometimes I like to add a blurring effect to my photos. What you can do here is to select areas of the photo which are unimportant and blur them out. This will bring more attention to the main subject of your photo. For example, if I had a picture of a flower and I wanted to play down the details in the leaves in background, I might add a blurring effect to the background.
