The final image that you see when viewing a digital photo today is most likely not quite the same as the image that was transferred from the camera to the computerit is better. A not-so-perfect picture can be taken to an almost professional level thanks to digital editing and enhancing. One such enhancement commonly used is the helpful sharpness enhancement. Adjusting the sharpness will improve the quality on a fuzzy or blurry picture.
Almost every editor has the sharpness too, sadly most of them aren't the best. The best ones use algorithms internally to help with the enhancement of the photo. This tool is extremely useful for blurry pictures or one with fuzzy lines and borders.
The resizing of a photograph is another commonly used tool today. Re-sampling is similar to resizing but is not as familiar to many. Let's take a look at the difference between the two. Resizing changes the pixels while re-sampling uses an actual algorithm to adjust the picture to appear to not be blurry, fuzzy or blocked. Some of the pixels will be doubled when using resizing to enlarge a picture.
When you resize an image reducing it, some of the pixels will be removed; this why some lines of the photo just vanish. Re-sampling on the other hand, uses algorithms to determine the new size of the pixels. While enlarging, color will be added as a result of interpolation. While reducing an image the actual pixels will be re-calculated. A quality image editor will consist of multiple algorithms for re-sampling and resizing options.
Big question for everyone is how to convert photo files in order to get smaller pictures. This is really helpful if you want to send photo files over the internet. There are two ways to do this: the lossless and the lossy formats. Lossless means that the image stays exactly the same as it was originally. Basically different methods are applied to get a smaller but virtually untouched photo. The most common format that photo software can hand is .png.
The disadvantage is the image can still end up too big, but the image will be completely unchanged. Lossy formats will actually lose some information. The advantage to this way is you will be able to pick the size you want it to end up in. The common form it is saved in is a .jpg. This will create small photos that will upload places quite easily. There are the ups and downs for both of these forms, basically do you want a smaller original or do you mind some of the photo being lost in order to make it really small.
Along with the importance of editing photos comes the importance of viewing your images. In order to easily access your photos your photo viewer should be able to be customized, easy to use, have printable contact sheets, photo enhancement tools, convenient for getting the pictures, be able to manage EXIF data and be able to batch process images.
Another good photo viewer is Photophilia which is exceptionally adjustable and able to batch process. Choose a photo viewer that you are comfortable with based on your computer skills. You can opt for a viewer that is quick and simple or go for a more complicated viewer that comes with some more functions. Handy functions to look for are slide show, batch processor, editor functions and zoom factor.
