Why do my camera raw files appear a lot brighter when viewed in Adobe Bridge than when viewed in the Mac Finder Window? Like a lot brighter. I'm not really sure which is the 'correct' brightness. Thanks!
Bridge shows the raw files according to the settings you have applied in ACR or if you have not applied any it shows the default ACR settings. The finder uses the embedded jpeg preview to show the contents of the raw file.
Without a screenshot it is hard to judge your situation but also check your Camera Raw settings (under Adobe Bridge menu see camera raw prefs) and in the default image settings be sure to have the option 'apply auto tone adjustments' unchecked.
You should first start Photoshop also to enable Camera Raw to function.
If this message still shows up then something is wrong with your install. Can you provide more details about set up and version numbers?
