RE: [APML] New E200 Pics - Orion & Perseus, reprocessed Veil

["Chris Schur" <cschur@therim.com>]

Stuart,

An interesting set of images.  The Orion shot while showing plenty of dim
nebulosity is way too red overall, and quite grainy.  Perseus is better,
albeit a bit purplish, and finally, the Veil is decent, with a slight
purplish background.  Also it seems a bit lackluster in contrast.

Suggestions:

1.  use the grey eyedropper in PS on discolored skies, possibly defocussing
a small piece to get an average

2.  Try Variations in PS or equivelent, it might help you pick the right
background.

Chris

Hi all - I have three pics to share. Two are new E200 (pushed one stop)
shots of Orion and Perseus respectively. The third is a reprocessed Veil
nebula which was a disaster in post processing the first time so I
backed off and tried to be more subtle this time. For the Orion shot, I
decided to totally lose control - comments, upgrades, scorn all accepted
with grace.

Orion with 50mm Nikkor lens at f2.8 and E200 for 15min manually guided
(remember I said I lost control here):

Perseus with 50mm Nikkor lens at f2.8 and E200 for 15min manually guided
(stayed cool and kept processing under control):

Reprocessed Veil Nebula taken with my f3.5 Nikon 400mm EDIF at f4.0 with
Supra 400. Seems pinkish to me but here it is:

This shot of the Veil was the first time I think I've managed to produce
a layered mask to remove the effects of vignetting. I copied the pic
into a second layer then did an extreme Gaussian Blur on it then added
it back in Difference mode with 50% opacity. Kind of feeling my way.
Would appreciate comments on how to do this better.
