Editing Digital Photos With Photoshop

By David Peters


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 computer it 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.

While almost every editor has a sharpness adjustment, most of them are not top notch in their results. The best ones incorporate internal algorithms to help enhance the photo. A blurry photos or one with fuzzy borders and lines can be greatly improved upon.

Today, one of the most commonly used tools is resizing a photograph. What is less heard of is re-sampling. What is the difference? Well resizing is just changing the pixels, while resample is using an actual algorithm to fix the picture so that is appears not blurry, fuzzy, blocked when it is changed. With resizing to enlarge a picture some of the pixels will be doubled.

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.

Another popular question for people is how to convert photo files to get smaller pictures. This process is beneficial if you want to send photos over the internet. You can do this in two ways known as the lossless and lossy formats. Basically, one of these two methods can be used to create a smaller nearly untouched photo. Lossless means that the image appears the same as it was originally only smaller, but only to a certain degree. The drawback is that the final image may still be too big but it is completely unchanged. The most common form it is saved in is .png.

Lossy formats will actually lose some information. The advantage to this method is you will be able to chose 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. You will have to decide what will work best for you. Do you want a smaller original or do you mind sacrificing some of the photograph in order to make it as small as you want.

Another important factor is viewing your images. Your photo viewer should be able to be customized, simple to use, come with photo enhancement tools, printable contact sheets, be able to manage EXIF data, suitable for managing photos and able to batch process images. Zoner Photo Studio is one such viewer that can provide all of these elements and is user friendly.

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.
