I guess that would be fine in some situations. It seems kind of a > waste though... my undestanding of the shooting in RAW preference for many was that they used this as a corrective tool after the fact, relying on full information capture to compensate for having set the camera up poorly before shooting. White balance anomalies and the like were easily correctable when all the data is available to fiddle with. I guess I equate this to the shooter who relies on the automation of their flash, light metering and focus to get the shot right in a film based camera. Maybe I'm being too critical, I don't know, but for me I have a distrust of relying on any auto functions to make mistakes for me as I prefer to take the blame entirely when and if things go wrong - at least I stand a chance of learning something ;-) I also understand the distrust of jpeg stems from the hazards of post image making when manipulating the image - a crop, a rotation.. a small colour correction and true data is lost and replaced with interpolated junk. A quick resize (more data gone), save, and what's left is a far cry from the original. This of course can easily be overcome by immediately saving the image as a TIF once downloaded to the 'puter (and not the post-photoshop 7 TIF either*) then with all the data intact, manipulating to one's hearts content without fear odd data loss. Best of both worlds - small image size in cameraa, maximum data preservation during processing. *the stab at TIF is over the the Adobe ® owned TIF file format which has been re-engineered with greater compression in the latest incarnations of PhotoShop® than before - it is no longer the lossless format people knew and loved. karl
