Re: [APML] M31 With Aurora (or is it light struck film)



Thom,

I concur with Jason, light leak.
I had an almost identical result a few years ago while shooting M8. Same red
"pillars" in one area like your friends.
I ended up blaming it on a red flashlight. It happened just after I started
using N2 purge on my OM's and my purge hose was a clear hose.
Must have hit it with the red flashlight....????.....Anyway, I painted the
hose flat black and have never had it happen again.
Just my single experiance for what its worth.
