RE: [APML] Orion Re-Processed - Opinions sought

Eddie, You have plenty of red nebulosity in your shot, but are you at sky
fog limit on each slide?  Scanners tend to add lots of noise to dark slides,
and I usually like to get the background up to at least a medium gray color
for best results.

Subject: [APML] Orion Re-Processed - Opinions sought


Inspired by the recent wonderful wide field postings of Orion by Andreas
Rorig and Marco Lorenzi, I went back and re-processed my wide field Orion
film image, and seek opinions on how I have done (My PS skills are improving
but not quite there yet :-)

2 x 20mins stacked/OM1 & Zuiko 50mm F1.8 lens at F4/E200 slide film

My original processing looked a bit harsh by comparison:

Re-Processed here:  http://www.astropics.co.uk/orion_ave2_16_1SGBNR.jpg

I noticed in a recent Tony Hallas post that he can "multi scan" 16 times to
reduce S/N. Vue Scan has a similar function and so I re-scanned the slide
using "multi pass multi scanning" set at 16 passes to hopefully get better
S/N.

In processing the image I could not get all of the detail in Barnards Loop
that was present in the original slide so I blended in the red channel as a
luminance layer (RRGB??) which seems to have had the desired effect.

Anyway, I would appreciate any comment or critiscism on what I have done

Thank you

Eddie Guscott
