The RAW file format is the uncompressed data file captured by a digital camera's electronic sensor. Shooting in the RAW format, digital cameras save images that are untouched by the processing settings like contrast, white balance, sharpening and saturation. It would be the equivalent to exposed but undeveloped film- the image just as you shot it without all the determining factors of how it may look after it leaves its source. Any photographer can understand why this is so important, any of those alterations can deteriorate image quality in the long run- and in most cases a photographer would want total control of their images and process. Its not always necessary to shoot in RAW, for instance taking snapshots or even doing some grip work JPGs would be sufficient. When doing landscape work with a digital camera shooting in RAW is a must. Mainly because landscape work is really meant to be shot with land cameras for superior quality. Anytime a lot of digital manipulation is involved, it is imperative to shoot in RAW- the more u save a file in JPG the more the file deteriorates.
I've been having some major issues with this because of my new digital camera. Apparently the new types of RAW files created by newer cameras are not supported by older versions of photoshop, and even with a new version you have to figure out ways around the files not being recognized. Almost 2 weeks later, I've resolved this issue. Photoshop CS4 and a DNG converter later, I can now open and edit my new CR2 RAW files. Seriously stressful business. Got some catching up to do.
