You want to shoot the highest res image you can print out. You don't tailor the test chart to the expected resolution you think you are shooting for. I looked at the 720p tiff, it is horribly aliased and barley suitable for shooting with an SD camera.
Again, print out the maximum quality that your printer can make. Use glossy paper if it's 8.5x11, it can hold more resolution. Let the camera see the best quality image, and let the camera throw away what it can't see. That is how res testing works. -Les |
Les is correct. Don't print the charts that I downres'd, *use the PDF* instead.
I downres'd those examples as benchmarks for what we might expect to see as pseudo-best test results. I suspect we should find that actual frame grabs will reveal even less detail than the "best" case scenerio samples that I posted. For example, in the 1920x1080 HD resolution image, notice how the lines break down in the 14 mark area. Because this is a 1920 rez image, it should be able to cope with more lines per picture height, but because of losses in PDF to image rasterization, and antialiasing, 14 is about as much as we can get. DVCPRO-HD has a max recorded horizontal resolution of 1280, so we'd expect to see noticable gray values near the 12 mark, in an ideal world without more loss. Bob |
