I'm trying to process some of my eclipse images from last night. For the umbral eclipse, when half the moon was brightly lit and half was dark, I took exposures at 1/50-sec and 2.5-sec to properly expose each part. Now I'm trying to merge them. Unsuccessfully. An HDR does not seem to work for this, and the various blending modes don't, either. The problem is that for the 2.5-sec shots, the brightly lit part is completely saturated. I can't seem to figure out how to basically do an overlay of the 1/50-sec part on top of that such that it blends well. Has anyone done this type of thing before or does anyone have ideas?
