Rosemary - I'm interested to know how to do the thing you mentioned in Painter, with recording the processing done on a small image, and at a later date apply the same tecnique to a larger image.

Ideally I'd like to be able to the same in pspro too - is that possible?

When I asked about applying p-p to samller images, I wasn't suggesting that I would then interpolate them to the larger size. Rather that I would then apply the same p-p to a newly rendered larger image, having already decided how by working on a small image first, and having saved the info about how to do it - if that makes sense!

Kelly - as I said in the initial post on this thread, I am not in the least bit interested in the pure / impure fractal argument, only in ending up with the image I want, in a reproducible form. So far I've only been able to achieve that reproducability by sticking to getting the finish I want in UF itself.
