Another aspect that should be mentioned is that camera makers' RAW formats are all proprietary across the board and altered from time to time behind the scenes. Whenever a camera maker may at some point choose to discontinue support for a certain version of their RAW format or one of their given RAW formats altogether people may have to convert all of their images in order to be able to keep viewing and processing them with newer versions of the software of their choice. Or even worse, there may not be a converter because a company may go belly up without having had a code escrow implemented for their RAW standard so that the standard may just perish along with its maker... disclosed standards are always preferable IMO - another reason to prefer Pentax Cheers Ecke
