I recently got some images from film that was scanned at a lab. When I imported these jpegs into LR4, They gave me an unhelpful error, invalid image or something like that. So in LR4, they are blank.
When I open these files in Photoshop CS3, I get a more helpful error message, "the embeded ICC profiles cannot be used because they are invalid. Ignoring the profile."
These images open up in CS3 and are viewable.
I do not understand the nature of this problem. Can someone help me understand what is going on? These images are black and white. Why can CS3 view the images but not LR4? What is lost when an ICC profile is ignored? What are the consequences of this? Finally, what would cause a ICC profile to be invalid?
Thank you for your help!
