Fisheye light fall off

[Ben Kreunen <ben@xxxxxxxxxxxxxxxxxxxxxxx>]

Well the negs are drying and it looks like it's full marks to Otto for 
spotting the obvious. My original problem of light fall off does appear to 
be due to the fact that I was shooting wide open.  Even from looking at the 
wet negs there is some visible fall off at f5.6 and quite a lot at 
f4.  It's also the first time I've shot at f11 so it sill be interesting to 
compare.  Ran out of film at that stage but I'll have to do the full range 
on my next film to compare the smaller apertures as well.  I'll post some 
images tomorrow.

Cheers

Ben
