RE: [APML] Another M42 - again

Clayton,
That is very nice!  Not much to suggest.  Perhaps a little more color
balance favoring green, a little less blue in the low levels.  Very minor
adjustments.  It looks great as is.  Congratulations.  I am not aware of a
standard color adjustment.  It would be dependent on the film as well I
guess.  You have done a wonderful job with this.

Subject: [APML] Another M42 - again


I have been reading the discussions about Steve's wonderful M42 with a great
deal of interest.  I have been using the suggestions made to him to process
this M42 that I took mainly last Sunday night.  I took all of these shots
through a Lumicon Deep Sky filter and I was amazed at how much color shift
that I got.  I have been struggling to correct this color shift and have
made some progress - but not enough.  Do any of you have a standardized
"correction" formula that you use to correct for shooting through this kind
of filter?  Perhaps the final answer is to get the IDAS filter which, I
understand, does not inject such a radical color shift.  The shot can be
found here:

I would appreciate any comments or suggestions.

Thanks
