Get more secrets to Editing Digital Photography

By: Dan Brown

Image editors (also known as photo editors) allow you to create and modify graphics and photographic images. This includes tasks such as painting and drawing, color correction, photo enhancement, creating special effects, converting images, and adding text to graphics. Your image editor will probably be your most frequently used tool for working with graphics so it should be flexible and intuitive. Many software programs are available for enhancing and otherwise working with bitmap images, but unless they can perform all of the tasks above sufficiently, they should only be considered as companion tools to your primary photo editing application.

Sometimes, people will try to store all their pictures on CDs, because their computer doesn't have enough memory to store them all. For the specific reason that having multiple discs to search through for a particular picture is time-consuming and therefore wasteful, it's a good idea to get a database. A database allows you to keep track of which CDs contain which pictures, where other images are stored, and so on. You can keep your images anywhere, but it is the database that allows you to remember where exactly you put them. You don't actually put the pictures in the database, only information about them. This way it is easier for you to find them in the future.

The best thing about digital cameras is that it's easy to take thousands of pictures. That's also the worst thing about digital cameras. After you've owned your camera for a few months, you won't be able to find that great picture you took a couple of months ago if your pictures aren't well organized or named logically. Folders are the best way to organize groups of pictures, and the My Pictures folder is a great place to start. In your My Pictures folder, create a subfolder for each year: 2004, 2005, 2006, and so on. This might seem silly the first year you own your camera, but after five years, you'll be glad you did this because you can go back to your 2005 folder and easily find a picture from a vacation you took that year. Arranging pictures by year is also helpful if you're scanning older photos stored in shoe boxes or albums that you took before owning a digital camera. This is also a good way to start organizing the pictures that you currently have on your computer.

When photos are saved on a computer, they frequently become slightly blurred. They are not necessarily so blurry that you can't see the image; they are merely not as clear as they could be. Just about all photo-editing programs have a tool that allows you to sharpen your image. When your image could use some sharper detail, this is the option you want to use. It makes for a much better-looking picture. Some cameras have the tool built in, though sometimes that is not enough, and it may have to be done again with your editing software.

Sharpen filters bring out detail in images by increasing the contrast of pixels next to one another. More advanced image editing programs offer several options such as Sharpen, Sharpen More, Sharpen Edges and Unsharp Mask (USM). Unsharp Mask gives you a lot of control over how an image is sharpened. Sometimes a photo will benefit from selective sharpening. You select an area with a programs selection tool and only sharpen the area. The important thing is not sharpen an image too much. The sharpening tool that is most useful for photographs is the Unsharp Mask, now available in most raster programs. The Unsharp Mask searches through your image looking for where colors change, and sharpens those areas. The Unsharp Mask is superior to any other sharpening because it makes decisions based on adjacent pixels, not random color changes, so it usually can find and sharpen just the true edges of color areas.

Digital cameras, even relatively cheap ones, take incredibly large images. However, looks can be deceiving and, while the pictures may look big onscreen, they may look disappointing when you try to adjust them for printing, emailing, or long term storage. They're best left untouched, if possible, so that you have more flexibility later. All photo editing software will have a command for changing the pixel dimensions of an image. Look for a command called "Image Size," "Resize," or "Resample." When you use this command you will be presented with a dialog box for entering the exact pixels you wish to use.

Cropping refers to the removal of the outer parts of an image to improve framing, accentuate subject matter or change aspect ratio. In the printing, graphic design and photography industries, cropping refers to removing unwanted areas from a photographic or illustrated image. One of the most basic photo manipulation processes, it is performed in order to remove an unwanted subject or irrelevant detail from a photo, change its aspect ratio, or to improve the overall composition. It is considered one of the few editing actions permissable in modern photojournalism along with tonal balance, colour correction and sharpening.
