I need to send 15 tiff files through an FTP site for an upcoming exhibit, and having exported files to the required specs find that they are huge, compared to exports straight from Photoshot set to exactly the same parameters - almost 3X larger to be exact. These are 16-bit grayscale scans of 4X5 negs.
I could export each one directly from Photoshop of course, but I like the look of the files, which I have altered slightly using the develop settings in Lightroom 2.
What to do? There are tight deadlines, of course. I should get these out tomorrow if possible.
Help asap - LR tiff export 3X larger...Jan,
Lightroom can only export greyscale images as RGB (3 channels), hence the file being 3 times larger than Photoshop. However, you can use the Edit in Photoshop command (Ctrl/Cmd+E) to send the Lr edited greyscale file to Photoshop, convert it back to greyscale (single channel) then save it from there.
Help asap - LR tiff export 3X larger...Thanks, Ian. That's good info to have. In this case, I may as well tweak the files in Photoshop, make an action and go from there.
