I am curious how Autointegrate combines multiple master lights. Suppose I have two luminance masters from the same or different cameras. Image integration requires at least 3. How does Autointegrate integrate 2 lights?

Thanks  
Kurt

Hi Kurt,

AutoIntegrate just duplicates the first light image to get the required three images.

Thanks Jarmo. That is interesting. At first glance if the masters have different SNR’s it seems that the first image then should be the lower SNR, Is this the first image that was loaded into Autointegrate?

My understanding is that the “best” image is first in the list for image integration. At least that should be the case when you have run subframeselector inside autointegrate. So the best image should then be duplicated. I guess another approach could be to duplicate both but now only the first image is duplicated.
