  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I'm going to get a NeatVideo calibration target printed at Kinko's, and thought I might find an image to test lens focus?

This one might work with some Photoshopping to copy one of the corner tests to the center?

BTW - here's the NeatVideo noise calibration targets

Also, found an interesting thread with a free chart for testing AutoFocus:

And this version of the ISO 12233 chart created at Cornell seems quite useful:
