Digital photography has made it possible to get a good result from a difficult situation where using film it may have been impossible to get a useable photo, this is especially true where the photo is taken under mixed lighting, digital cameras allow for the white balance to be set and post processing can correct colour casts.
A lot of the benefits of digital reply on post capture computer processing using Photoshop or similar software, unlike film where once the shutter button is pressed further options are limited and usually involve time consuming darkroom work.
Digitally processing and enhancing an image does take time and requires an understanding of the software but in many cases the original ex camera image can be used without enhancement but it may still be necessary to adjust the resolution/file size for its required end use.
