DBE and LP gradient
« on: 2013 December 16 14:57:47 »
Here is a scenario. I`am shooting an object which has are lot of LP gradient. During the night object moves and the LP gradient changes. So I`am wondering, would be a final result better if I first do an ImageIntegration and than run DBE, or if I first apply DBE to individual subexposures, and than do the ImageIntegration?

i have done that - the resulting gradient in the stack is much easier to clean up.

however DynamicBackgroundExtraction can not be used with ImageContainer so it's kind of a lot of work to do DBE manually to a lot of images.

Tnx Rob.
I thought if I run DBE first, and clean up the images, maybe there would be more details in final stack.
