Make Your Own ISO Camera Test Target
Ever fancied testing your camera using a professional test target? Well, DPNow are reporting that you can download an accurate replica of a resolution target for free:
“Have you ever wished you could test your own camera like the professionals? Here at dpnow when we test digital cameras we use a variety of test targets, including the standard ISO 12233 resolution target for testing electronic cameras. It’s a pretty standard test used by a lot of reviewers. Our target cost us over ?100 (approx US$180 or EU?150) but is vital to our battery of camera tests.
Stephen H. Westin, a research project leader at the Cornell University’s Light Measurement laboratory, appears to have created a replica ISO 12233 test target using ISO specifications and made a pdf version of it available for free download.”
