A good topic here, Herman. I was also surprised to see the changes when I updated to the 64-bit version. Unfortunately I am not nearly as impressed with the new release as I was with the older versions. For me, the tool is still going a good job at creating the stitch at the pixel level, but it is doing a horrible job with image quality. I've provided a couple of examples below. If anyone has heard of a fix for this I would be glad to hear about it.
1) Creating Artifacts: Never did I see older versions of MICE create artifacts (for lack of a better description) during the stitch process. I've marked the artifacts below with arrows and ovals. The arrows are pointing to small, rectangular, de-saturated shapes creating during the stitch process. The ovals surround diagonal streaks of moderately de-saturated streaks in the grass. All artifacts seem to reoccur at somewhat regular intervals across the image. The second image is a 1:1 crop of both areas.


2) Exposure Blending and Color Management: I always thought one of the best qualities of MICE was it's ability to blend exposures, and the new ICE claims to have automatic exposure blending. What I find really frustrating about this problem is all of my original exposures (straight from the camera) were matched exposures to begin with. Furthermore, I ensure all exposures have matching exposure value and white balance through my raw conversion. The arrows in this image show panels that seem to occur in the stitch where the exposures in each panel vary from left to right. Additionally, the blues in the sky in each of the lighter panels is way off.
