I suppose so. Think of align-image-stack. I think with merely 70% overlap it might refuse to work - even with a severe tremor, a long lens and no tripod I think everyone trying to do an exposure bracket would do much better than 70%. I think the 70% may come more from a wish to create an exposure-fused panorama from a lot of random shots by grouping them so that some stack-like bits can be had, but I suspect this scenario isn't really all that frequent, and the results might not be awfully good, then, either. > >Changing the threshold does not help with my initial problem with > >images from different lenses.

I tried a simple test case, and it seems to me that the smaller image is simply ignored by enblend and only the larger one is taken - sort of makes sense, since this results in the least amount of seam and blending artifacts. It also fits my experience - I'm doing a fair bit of panoramas where this precise thing happens, so I always have to use masking to see anything of the smaller images at all. What do you mean by 'horrible things'? And did you really mean enblend? When Fusing two differently-sized images with enfuse, I couldn't detect any 'horrible things' happening, either, so, really, I don't understand your comment.
