Digital cameras typically produce one or two types of files – JPEG and RAW. Most amateurs work with JPEGs, while most professionals prefer to work with RAW files. When you are dealing with a RAW file, you are working with a much higher quality original than you would if it were JPEG. You also have a greater control, which means more creativity, when you make your adjustments, corrections and manipulations. Digital camera manufacturers provide special software for processing their own RAW files. Among the list of such cameras you can find Canon EOS-1DS, supported by ImageConverter Plus.
