Custom Lens Profiling with fisheye
« on: March 17, 2011, 02:21:45 pm »

I just did my first custom profile and it was fairly painless. However, since it was on a fisheye lens, I'm trying to figure out how to make the calibration ignore the curvature and just fix things like CA and vignetting. What it did was convert it into a rectilinear image, which isn't what I want. My guess is that Geometric Distortion Model needs to be unchecked, but that is grayed out.

Thanks,

Mark

This isn't a direct answer to your question, but couldn't you just make a preset for the chromatic aberration and vignetting and thus avoid the problem?

I've done that already, but wanted to experiment with the lens profiler program to see if it did a better job than what I had done. I was surprised there wasn't a way to disable this correction when they clearly have a separate approach for fisheye lenses in the process. I do plan on running my rectilinear lenses through the paces and see what the results are like.
