Imported photos look normal, then turn dark one by one
Hello, When I import my photos into Lr 4.1, they look normal & balanced, then turn very dark, one by one. I can visually see this on the filmstrip. I am not sure if this is a JPG preview I am seeing...They do not show up like this in my Pictures folder nor in CS Bridge.
I shoot a Nikon D7000 in RAW always, shoot on Auto, Manual, Apeture, etc. I am running on a Windows Vista 32 bit, but import as TIFF files in 16 bit and work with 16 bit files. I usually set my camera to no saturation, or very little, no sharpening, etc., preferring to work with the RAW file only.
Thank you in advance.
