RE: [APML] Funky Purple Horsehead Questions



Allan, does the raw slide look that purple and pink when you hold it up
to the light?  How about other shots on the roll?  Stupid question but
your lab did know to process it E6 right?  I have seen some pretty weird
color shifts via cross processing (E6 developed in C-41 process).

Subject: [APML] Funky Purple Horsehead Questions


Hello everyone-

A bunch of newbie questions that I could not find answers for in the 
archives!

I shot this a few nights back using E200. Didn't expect it to be great 
- but was surprised at a number of things when I got it back from 
development and was hoping the group could help me understand what's 
going on. First off - it was a 60 minute exposure with an 8"  f9 VC200L 
from Vixen guided by an ST-4 on a G11 mount taken with an Olympus OM1. 
It was developed by a local lab with no special instructions and I 
scanned it on my SprintScan 35 plus.

Questions are:

Why do the star images on the left and right sides have "comet tails" 
pointing toward the center?
Why's it so darn purple & pink (is this usually just processed out)?
Are the vertical lines across the entire image typical of this film 
(grain characteristics) or is it bad processing?
What would cause the hot pink vertical line in the lower left?
Also - its hard to see but there is an odd bulls-eye shaped 
imperfection in the lower center - any ideas?

E200 seems to be the preferred film these days - but based on this 
result  - I need to work out a bunch of issues!

Any help is much appreciated!
