While almost every editor has the sharpness enhancement, not all are top quality. The best ones use internal algorithms to help enhance the photo. The sharpness tool is exceptionally helpful for blurry pictures or one with fuzzy borders and lines.
Another common tool used today is photograph resizing. What many people are not as familiar with is re-sampling, but what is the difference? Resizing is a term that refers to changing the pixels. Re-sampling uses an actual algorithm to fix the picture to appear not fuzzy, blurry, or blocked after being adjusted. When you resize a picture enlarging it, some of the pixels will be doubled.
While with resizing, reducing an image some of the pixels will be thrown out; this why some lines of the photo just disappear. Re-sampling on the contrary, uses algorithms to decide the new size of the pixels, during an enlargement color will be added as a result of interpolation. While reducing an image the actual pixels will be re-calculated. A good image editor will include multiple algorithms for re-sampling and resizing options.
One of the most asked questions is how to convert photo files to get smaller pictures. This procedure is especially helpful if you want to send files via the internet. The two methods of achieving this are the lossless and the lossy formats. The image remains precisely the same as it originally was with the lossless format. Essentially different methods are applied to get a smaller but nearly untouched photo. The most common format for photo software 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.
Viewing images is just as important as editing them. In order to easily access your images your photo viewer should be able to be customized, easily to use, have photo enhancement tools, printable contact sheets, convenient for attaining pictures, be able manage EXIF data and be able to batch process images. Some good ones are Zoner Photo Stuido which is quite user friendly.
Another is Photophilia which is extremely adjustable and able to batch process. Selecting a photo viewer is important, depending on what kind of computer user you are you can select a viewer that is quick and easy or complicated but has some great functions. Some handy functions are: slide show, batch processor, editor functions, and zoom factor.
