Your camera vs. USM
Posted: Sat Nov 29, 2003 11:25 pm
I wanted to see how my camera's on-board sharpening parameter would fare against Photoshop's USM filter. So I did a little experiment, the results of which are posted here: http://www.pbase.com/ang1970/olympus_vs_usm.
The first three shots (c3kz-hard.jpg c3kz-med.jpg c3kz-soft.jpg) are taken one after the other, on a tripod, with all settings exactly the same except sharpness. Sharpness settings are reflected by the filenames, respectively HARD, NORMAL, and SOFT.
Here is the EXIF data for the shots.
The two later shots (usm-hard.jpg usm-med.jpg) are edits of c3kz-soft.jpg, the shot taken with the least amount of in-camera sharpening.
USM settings for these two edits are as follows:
Please post your comments/observations here. Also, if you're inspired to do the same type of experiment on your own camera (and I hope you do!), please post the link in this thread. Include as much info as possible, for a thorough comparison.
