Digital cameras can store two types of photos files. The most common are JPEGs, a compressed and standardized image file that all computers recognize. Some cameras can store RAW files, the raw data coming from the imaging device. Each manufacturer has a proprietary raw file for their cameras, sometimes referred to as digital negatives or DNG files.
Adobe's digital camera profiles allow users to import and edit image files from a wide variety of cameras.
Photo editing programs must convert the manufacturer's proprietary format, so Adobe offers a free DNG converter to perform that task. New digital cameras come on the market regularly, so the Adobe DNG camera profile updates frequently.
Your photo editing program should have instructions on how to install the DCP - Adobe DNG Camera Profile.
