APG 2.5 B2 color correction issue

by bvogl » Tue Nov 30, 2010 2:30 am

I searched the messages but i didn't find any post about that:
When creating large panoramas the color correction doesn't work as expected. After initial detection one reference image is set and color correction is set to "on".
1) As you can see in image 1, colors start to shift and even some weird color areas are visible.
2) Changing to "gamma only" will leave the colors untouched but you can still see that brightness values are not correct (image 2)
3) But the biggest problem of all is, that all subsequent changes are ignored - only the image you are touching is changed in some way (see image 3 where i added a color anchor on top of the tower). This leaves you in a situation where the panorama color is must be calculated correctly after initial detection or you can throw away the project and change to PTGui ;-)

I'm not sure how much of the engine was taken over from the 2.0 version, but there were similar issues with the old engine and large panoramas.

Best regards

I'm having a similar issue. I'm trying to turn autocolor off, so I set my prefs for the group like this:


But here's what I'm getting:


This is from RAW files using 2.5 beta 2.

I'm still working on color correction in 2.5 engine, so even in beta 2, it's not fully patched.
