Digital cameras usually require a computer and associated software to recreate and edit the image. A computer meant for digital photography should be fast enough to process the high definition images from the camera and easily modify them. It should have a high amount of RAM that can handle pictures with millions of pixels easily and edit them quickly. A computer needs to be installed with professional image editing software such as those sold by Adobe, Corel, Apple and others. 

Adobe Photoshop is by far the most popular image editing software. Although it has an intelligent interface, the myriad tweaks and effects it can help produce makes it a highly complex software. If you are serious about photography, whether as a hobby or a profession, you will need to spend considerable time learning this software.

Image editing is mainly of two kinds, one being tweaking, and the other, creating effects. Tweaking involves removing defects present in the original image, while effects are embellishments made to enhance the aesthetic appeal of the image. Tweaks can remove red eyes, or adjust exposure, color balance, contrast, brightness, and manually tweak the photograph’s visual. Effects can produce halos, vignettes, cloud bursts, and a host of interesting graphical effects.

Most professional editing software are expensive and quite complicated. Software help unleash your imagination and innovation and make sure your pictures are differentiated from others and better than the original. A powerful laptop is necessary if the photographer plans on shooting away from his or her studio and also modifying the captured images.
