Re: [APML] first try
Thanks for the info guys. The images was with an OM-1 with a 50mm lens shot
at f4 for 25 minutes on Elitechrome 200 in dark skies at TSP, however, there
was lostsa moisture in the air that night. Only one night was really
good... late Tues. morning. The image I posted was a hodge-podge of
processing, which accounts for some of the problems... try something and see
if it works :-) I did do some bluring. I did use levels and tried to cut
it close to the tails... guess too close.
