| p.1 #5 · Raw file previews turn dark after import |
are you using lightroom? if so it's likely changing the camera calibration profile on import to Adobe Standard.
you can prevent it from doing this if you import an image, let LR make the change to Adobe Standard, and then go into the develop module, camera calibration panel, and change the profile back to whatever it is you want to use (Camera Standard, Camera Faithful, or whatever your body has available.)
once you've changed the profile, go to the Develop menu and go to Set Default Settings. this will allow you to override the existing import settings with whatever changes you just made to the profile.
one warning: don't do any other processing on the file other than change the camera profile before you update the default settings, or else those changes will be saved as well and applied to imported photos in the future. for example, if you set sharpening to +50 and then update those import settings, everything you import will always receive +50 sharpening, etc. if you screw it up you can always restore the defaults so no biggie.
