RE: [APML] reprocessed M33 and Irfanview

["Jeff Ball" <jeffball@netacs.net>]

thanks to Jim, Bobby, and Matt,
I reprocessed with lower BGSmooth numbers. Matt, I know you say use high max
diff numbers, but my images are much more mottled with high max diff than
with low.  Could it be the way the Windows interface inputs numbers into the
program?  Do you use the Windows interface version?  I use low radius and
low max diff.  I tried the 1.5 and 60 and the image was blurred way beyond
usefullness.

Again, can you identify compression artifacts and is there anything I can do
other than save at higher quality .jpg?

Thanks so much.
