I use Lightroom (version 3 now, probably 4 soon) to work with my raw images. When exporting to JPEG, Lightroom applies a number of adjustments, even if I leave all the settings at the default.
This is correct for raw images, but I'm now having a bunch of prints and slides scanned to TIFF, and the scanning service will do basic adjustments for me. I'd like to store the TIFFs in Lightroom so I can keyword and organize them, but when I export, I don't want Lightroom to do anything to the image other than convert the TIFF to JPEG. How can I achieve this?
