Re: [APML] Stacking Software

to save time, start off with 4 points in each corner.. then add one in the
center for good luck. Refine, do an "absolute difference", zoom in to the
preview window so you can see pixels (usually 4x) and check several areas
of the frame for alignment issues.. add points there if needed. Its
extremely fast even with a duron 1100 PC, it takes longer to write/read the
50mb files from the hard drive than anything else.

The nicest thing about PW is how efficient it handles huge files with
little memory.. it sure beats PS in this regard. I shudder everytime I open
up a 100mb file in PS, I expect flames to shoot out of the back of the
computer (g).
