My understanding is that this is a common fallacy. While it is true to say that if an image is overexposed so that a particular pixel is clipped to white in all three channels (R/G/B) then it is completely blown out and there is no highlight detail recorded. Therefore many people opt for underexposure to avoid blown highlights.
However the linear nature of digital capture (
http://www.luminous-landscape.com/tu...se-right.shtml shows that 50% of your data is in the brighest 1/5th of the image) making it preferable to err on the side of
slight overexposure rather than underexposure, because underexposure will make your shaddows noiser than they need be.
It follows that if you underexpose by just 1 stop you throw away a MASSIVE 50% of possible data, 2 stops underexposure throws away 75%
For anyone using Adobe Camera RAW, turn off the auto/default setting (after all you don't use your camera in fully auto mode do you
, and get Bruce Frazers excellent book Real World Camera Raw to get the best out of your software.

What has been happening is that the pictures look ok in the camera or in Picasa but when I open them in RAWshooter they are terribly dark I usual have to lighten them by two or three exposure steps plus sometimes some fill light. There may be something wrong in the camera settings but I can't see anything out of wack. Everything seems fine in pictures taken as JPEG. Digital Photo Prof. also gives me dark shots so I don't think that it's a software problem. Any advice would be appreciated.

Snowy - I understand that the main functions in RAWshooter are similar to ACR so you may find the book useful.
Assuming you are on broadband, if you want to email me one of the offending RAW files, I'll have a look at it in ACR
