I have a client whose studio I set up with Lightroom 3 who regularly deals with very high-resolution drum scans of 8X10" film. She has tens of thousands of scans and other files that need to be organized, and I was hoping that I could use LR3 to do it. However, when I attempt to import the scans into LR3, I repeatedly get a message that tells me that some of the files are "too big." The error dialog allows me to locate the problem files, and they are always TIFF scans form 8X10" film done with and Aztek.

I called Adobe tech support about this, and was told that there is a 65K X 65K pixel dimension limit in LR3 and PS CS5. All of the files in question are below that limit. When I mentioned this to the tech support rep, he became confused. After muttering about 2GB file size limit for a while, he told me that I should use "professional software" such as Bridge. I asked him directly if there is a 2 GB file size limit, and he said there is not.

Since that time I have done a great deal of research online and in various textbooks, and there seems to be some disagreement about the maximum file size limit in terms of actual, practical applications. I would be very interested to hear from those in this forum on this topic.

According to the LR3 manual:

File format exceptions
Lightroom does not support the following types of files: PNG; Adobe Illustrator®; Nikon scanner NEF; files with
dimensions greater than 65,000 pixels per side or larger than 512 megapixels.


So if the scans exceed 512 MP, LR3 won't import them.
