  • Sharpening

    Digital photo editing beginners often misunderstand what the Sharpening tool can do for a photo. The first thing to remember about Sharpening is this. It doesn’t matter how good your photo editing program is, you cannot fix what wasn’t already there. No amount of sharpening is going to fix a bad, fuzzy picture. If you…

  • Red Eye Removal

    One of the most common problems in photography is the demonic transformation of the Red Eye effect. It comes from using a flash in a dimly lit area. Since the subject’s pupils are wide open, there’s nothing to prevent the light from the flash travelling all the way to the far back of the eye.…

  • Megapixels

    In the world of marketing digital cameras, megapixels seem to be the beginning and end of a camera’s power. Like a computer’s RAM and hard drive, “the more, the better,” and all of the other features of a camera fall by the roadside. But there’s more to a photo than the megapixels. The quality of…

  • JPG Compression

    “I’ve heard a lot of confusing stuff about JPGs. Some people tell me they’re perfect for online photography, and other people warn me that when I convert my pictures to JPG, I’m going to throw away most of the quality of my picture! I don’t want to ruin my pictures, so should I be using…

  • Digital Image File Types

    There are so many different file types to choose from, like RAW, JPG, GIF, TIFF, and PNG. Which one is right for you? RAW is the internal file format for many digital cameras. Photographers like to shoot in RAW format because it doesn’t get any processing in the camera, allowing them to adjust things like…

  • Cropping and Straightening

    Imagine returning home from the family reunion, camera in hand, and waiting for the printed pictures to come back. After a delay of at least hours, sometimes even days, the prints arrive, and in the most important picture–the family reunion shot–not only is there an ugly glaring neon sign in the background, but the tripod…

  • Cloning

    Cloning, in digital photography, has absolutely nothing to do with sheep. Unless, of course, you want to use the cloning tool to turn an image of one sheep into a whole flock of them. The Cloning tool is used to copy one part of the image into another area, or even into another picture entirely.…

  • Burning and Dodging

    While Burning and Dodging are listed as tools in most photo editing software, they are digital versions of techniques originally developed by darkroom photographers years ago. Burning is a trick for getting more detail out of a section of a picture. The photographer makes his print normally, and then masks off a large section of…

  • Brightness and Contrast

    In photography, exposure is controlled by a variety of things–the size of the lens opening, the film speed, and the duration the lens remains open taking the picture. In digital photo editing, we can adjust exposure further, with the Brightness and Contrast controls. Brightness, as the name implies, is the amount of light in the…

  • Blurring the Background

    The best Wildlife photography will always show a crystal-clear animal against a blurry background. This is done by using just the right combination of lens, aperture, and shutter speed, and really helps to make the subject stand out. If a background of branches and leaves were as sharply focused as the bird in the foreground,…
