I have two cameras, 7d and a T1i. Imports into LR have been without issue for years. All of a sudden my files from the Rebel are not importing correctly- They look fine until I hit import, then the file size changes (by about 3mb) and I get a large monochrome jpeg preview??
After a night of head scratching, as near as I can tell Lightroom is applying camera specific develop presets on import. The Raw files look normal when viewed in Explorer or Windows live view, and even in LR before I hit import. My presets folder is empty, the only thing I apply during import is a filename change and basic metadata. I tried different cards and updated the firmware, even updated LR to 3.6.
Is there another place in LR I should look for presets?
Edited to add: If I open the CR2 file in Elements it looks fine, and I've tried not converting to dng in LR but still get the same behavior.
