I dont follow you, if you have to do this processing at home with special ACR or Pentax sofware to open and print the RAW files, then its not as "portable" or "universal" a format as jpeg is which you can print directly from the media card at minilabs, no? that would seem to be a major feature of "shooting jpeg" if thats all you want or need. jco

As far as I can see, the only benefit of it is to store more pictures on the card. It is no more difficult to plug the camera into a printer and print from raw files. You can get usable results. Results that are at least as good as jpeg. To the best of my knowledge there are no intrinsic properties of raw files that force anybody to do any post-processing at all. All of the pictures that I have had from my Olympus, for example, have been perfectly usable without post-processing. Of course, this doesn't mean they are exhibition standard. But nor are jpegs under the same circumstances. You can do an experiment and judge for yourself rather than take my word for it. Borrow a digital camera, shoot some raw, some jpeg, and get some prints. If you think about the processes that are going on, it must be true. Suppose you decide that you are going to 'shoot jpeg', which only means you're going to store jpeg. You make an exposure which the sensor records. The software reads the data from the sensor, converts it to jpeg on the fly and stores the results. When you walk up to the printer and plug the camera in, the software in the camera reads the jpeg file and converts it into the format that the printer understands. If you decide to shoot raw, then when you make an exposure the software reads the data from the sensor and stores it without converting it to jpeg. When you walk up to the printer and plug the camera in, the software in the camera reads the raw file and converts it into the format that the printer understands. There is no reason at all why the same algorithm that makes jpeg results USABLE, as you put it, wouldn't be used on the conversion from raw to the printer format, since both processes start from the same place, and end up in the same place. -- Bob > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of J.
