When I would do Apo post, I would duplicate the base layer, 3 or four times. Add noise to one, a texture effect to two maybe, then maybe add a laquer filter to one, merging and playing with transparencies to suit...til I had an image I liked. Then I would flatten them, and start the process over, this time duplicating the flattened image several times, adding contrast, saturation, blurs, etc. Make sense? I realise I could do work arounds in PS or whatever, but I'm trying to stay pure to UF. But I think SimonKaye summed it up.
