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.

The display resolution of a digital television or computer display typically refers to the number of distinct pixels in each dimension that can be displayed. Some commentators also use this term to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters. An example of pixel shape affecting "resolution" or perceived sharpness is displaying more information in a smaller area using a higher resolution, which makes the image much clearer. However, newer LCD displays and such are fixed at a certain resolution; making the resolution lower on these kinds of screens will greatly decrease sharpness, as an interpolation process is used to "fix" the non-native resolution input into the displays native resolution output.

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 it comes time to touch up your digital photos, you will need a photo-editing program. You can choose a low-priced, consumer-oriented program or a high-priced program targeted at professional photographers. For most of us, the consumer-oriented programs are more than adequate-and, in fact, you might have received one with your computer or digital camera. Depending on what you do with your photos, you may not need a lot of the bells and whistles when it comes to photo editing. Explore your options and find out which software is best for you. If you're a beginner, you may be happy with a package that offers only the basics, like cropping and red-eye removal. Or, perhaps you need something with more creative effects. For the ultimate in photo-editing, you may consider investing in a professional editing suite. Be warned though, software like that is going to cost you. Adobe Photoshop, for instance, has become the industry standard among professional photographers everywhere. It allows functions like level adjustment, advanced compositing, and RAW image processing.

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.

At times the subject of a picture is lost in the surrounding parts of a picture. If this happens, you can always crop your picture. This means cutting down the picture to a certain size. There are many ways to do this in terms of the size of cropping. In just about every photo editing program there is a cropping tool, and you can experiment with the size of the area that you take out of your photograph. If you don't like what you've done, all you have to do is click "undo."

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.
