Re: [APML] M45 help



Scott, Bobby;
 
     Your film was purged three times, brought up to temp and purged again for the bake time.  You 'did' hook up your dry air lines before you turned on the air pump didn't you?  :) 
 
     If I remember the night correctly it was an average humidity night for down here.  The roll I hypered for myself at the same time was okay.  My roll was the newer RG200, remember we marked it. 
 
     Were the light leaks throughout the roll or just the exposed frames?  I remember one super bright light being shined on your camera while you visited our state of the art restrooms.  I didn't have any light leaks.  You might want to consider a shade for the viewfinder...joe  :)

Hi Scott.
I downloaded your M45 unprocessed file and played with it a bit. I did some anti-vignetting and tried some color balancing with levels and curves. What I ended up with wasn't all that far from what you got except perhaps a bit lighter on the background. One thing I did notice was some "funny" color on the background; some I'm not used to seeing. Sort of red and I had to add blue to balance it but I'm like you, I couldn't get a result I was happy with. I have not worked much with RG200 and it may be that I just don't have a good handle on how to do the basic adjustments for it. Did you purge with N2? How damp was your night? I've found that for hypered LE400 it certainly helps on the color balance to N2 purge on all but the driest nights. This could be a problem and it might be that hypered RG200 might react in a similar fashion.

The link now has both the unprocessed and processed version. Larger and less compressed.

Scott,

 

Do you have a larger, unprocessed file to look at?

This was taken 2 weeks ago during the new moon. I can’t seem to get the background color right with out loosing a lot of the nebulosity and severely clipping the histogram. I wish I had exposed longer, but this was the first actual shot taken with the NP101 and I wasn’t sure how long I could expose. Any suggestions?
