Very true! And keep those articles coming- always very interesting and informative. Also to Pintamiter- the Ken Rockwell website (post #5) above, clearly states too that you are wasting your time with small incremental scales with Genuine Fractals! Either you want to scale something up really BIG with GF (which is what it is really good for) or just use Photoshop. In fact even David Halpern (post #2) mentions the Photoshop scaling steps as a really good method- but time consuming- and this is what Orio's post covers -about Stair Interpolation 2 by Fred Miranda, using Photoshop Actions to do the stepping automatically. So a GOOD RANGE of software choices are there and available! It's amazing how many people you see "beating their heads against walls" trying to get Super Hi-Rez renders out of Vue when a FINE rendered setting at medium to high resolution- and then processed through Photoshop filters and/or actions- will give them the Super Hi-Rez they need- saving hours/days of rendering and frustration. etc.
