Basics of Digital Editing

The digital age has allowed for great advancements in the field of digital photography. Most importantly is the ability to readily and easily view images as they are taken. This is not an entirely new concept. Polaroid film has allowed for this possibility for quite some time. It is both available on specific Polaroid cameras, and also as adapters for large format cameras that would allow photographers to check focus, composition, and exposure before exposing on actual negative film.

This technology was indispensable and invaluable to photographers. The technology was not without fault, the film adapters and film were quite expensive, and this limited their availability to the casual photographer.

Things have become quite a bit easier with the advent of the digital age. Now photographers of all ages and types can cheaply and quickly review their images just moments after they are actually exposed. It is quite easy these days to check exposure, both visually and through the use of histograms, and also the check depth of field and focus quite handily.

The ability to edit images in programs such as Adobe Photoshop is also quite revolutionary to the new digital movement in photography. Photoshop has advanced technology and algorithms that are specially designed to work with the type of information that is captured by digital cameras, and allows for a wide variety of computations to the preformed on these image files. These include such actions as correcting and adjusting exposure, adjusting sharpness or blurriness, and changing color balance to be more correct, or to perform some type of special effect on the files.

Exposure is perhaps one of the most useful uses of Adobe Photoshop. It’s quite easy to eyeball image files, and to use functions such as levels, or auto levels to make dark images a bit brighter, or to make bright images a bit dimmer to fit your ideal exposure value. More useful still is to learn how to use histograms to be able to more precisely gauge exposure in image files. Histograms are also available on many high-end digital cameras, which allow photographers to have a more exact grasp on exposure values before even entering the files into the computer. Photoshop can also help out on with sharpness in photographs. This is not a perfect science, and even Photoshop can only correct files so far until they become unsightly due to artifacts and distortions. As always, it is be to get things right in camera the first time, and to shoot in RAW format for the best flexibility in post-production.
