I want to make a few large prints (24" and wider) with 5DMKII files, I have not done this before so I wanted to get some feedback before I submit my files for printing (online printing service). What method and amount of sharpening yields the best results after you upsample the TIFF file to the desired size? I tried smart sharpen with amount 100 , radius 1 and looks good on monitor but I have no idea how the print will come out.
Thanks
