Re: Raw

Ok guys, yeah: some cameras do some kind of processing on the files 
prior to RAW format output. But what the hell does that matter to a 
user of a particular camera? You can't do anything about it at all ... 
A RAW format file is as "untouched data from the sensor" as you can get 
from any camera, and no change in user settings like ISO, Contrast, 
Sharpening, Saturation, and Color Balance is going to change what a 
camera manufacturer does in a RAW format file.

I was trying to help Ann's understanding, not add yet more complexity 
to the discussion. Sheesh.

People on this list just love to pick everything apart on nitpicky 
details that make not one iota of difference to anyone. There's a lot 
of stuff about computers and operating systems, and digital cameras and 
film cameras, that no user/photographer needs to know at all.

If you want to use RAW format, working the camera becomes much 
simpler ...
NONE of the image processing settings you make do anything other than
setting up some data that the post-processing software can use as a
default. The only important settings are the sensitivity, aperture 
and
shutter speed, just like with film. You need to learn the sensor's
exposure response, that's all, and focus of course.
