It's happened to me a couple of times, andf now INSIST that the incoming
film is sent to the freezer immediately. I will sacrifice a "test roll"
from the brick of 20 rolls as a means of checking. If there is any base fog
it is returned for replacement along with half the sacrificed roll as
"evidence" It is then up to the dealer to argue with Kodak re the
replacement of the film... I do not particularly care who is the loser.. I
just know that it will not be me.

BTW try reversal processing to slides with the Tmax reversal kit. Puts your
EI up around 1200 and the grain is superfine. It is a bit expensive for my
pocket, but I am now in the process of finding my recipe for reversal from
"scratch chemicals". I had to make some E-6 slides of the methodology to
present to the local camera club (of which I am not a member) and afterthat
I misplaced the recipe.. but I have it all on slides.
Have you any idea as to where I put them for safekeeping?... I'l bet I find
them in the very last place I look!

Have fun
Ken


 I can confirm modelling lights would have been on for

If you use the modelling lights of "full" power you'll find that you may
not need the red filter either and basically "increase" the exposure  for
the film due to the Higher IR output of the modelling lamps.

Was there a great deal of "base fog"? or was it only within the "frame". If
it was a general "all-over fogging", I would strongly suspect that it was
'heat' fog due to improper storage. I have had film in an iced cooler "die"
when the ice was gone and the temperature inside rose close to ambient. It
does not take too much to "kill" it by overlong storage at temperatures
above 70 deg F
