    If I take a RAW file that looks well exposed in Bridge and open it in ACR and then zero out all the default adjustments (eg. Brightness=+50, shadows=+5, curves=medium) then I find that the pictures looks dark and flat.

    The same RAW file opened in Capture One looks similar to in Bridge, but here the default settings are already at zero.

    So what am I missing here? Why do Bridge and Capture One show a good image (presumably) with no adjustments applied, but in ACR it looks terrible if I take off the default adjustments?

    Thanks for any answers that can clear-up my understanding in this area.

    Although I don't personally like the Adobe ACR, My understanding is that each of the default values is based on your camera, This is why you sometimes have to update the ACR when new models come out.

    So although you are seeing what appear to be defaults for CS or Elements, What they are is Adobes defaults for your camera based on information contained within the EXIF data.

    I should add to my reply, By resetting them to ZERO you are removing camera specifics NOT a random default value.

    Having said that if you have Capture One, you would be wise to use that for RAW file conversion, As it's way better than the Adobe ACR.

    When you look at an image in Bridge, you aren't looking at the raw file itself, just an embedded thumbnail.

    In ACR, Adobe reads the raw file and displays the actual file using the ProPhoto colourspace. The file has what is called 'linear gamma' and will not be an accurate rendition of the 'real' scene as you saw it on the day.

    Once you save as a TIFF, ACR processes the raw image and applies the actual raw conversion.

    That's the best explanation I can come up with based on reading Bruce Frazer's book on Adobe Camera Raw.

    Do you know what the situation is with Elemnts 3.0 is that an embedded thumnail or the actual raw file?
