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. Special software is required to process RAW files from different camera manufacturers. Among the list of cameras supported by ImageConverter Plus you can find Canon PowerShot S90.
