Thanks. That deals with one end. Regarding the other, if I edit some image in Lightroom and then
1) click the "export to photoshop" button, make local adjustments in photoshop, sharpen, and then save as 16-bit TIFF,
or
2) export as 16-bit TIFF in Lightroom (no output sharpening), open in PS, make the same local adjustments, sharpen with the same settings, and then save as 16-bit TIFF,
will there be any difference in the two output files? I'm wondering about the technical details of what actually happens when one "exports to PS," since PS doesn't seem to be able to natively read raw image data.
