Thanks Bill,again.
I use the Yashica Mat in a similar way then,as it
is meterless.If i forget my meter i "sunny 16"
as per the speed of film in the camera,if i
remember it,i set ISO and read the results.

That is due to the different wavelength of IR compared to
red light - more IR will pass the red than "standard"
filter factors would suggest, that's all. Trust the Force,
shoot manual, as mentioned. Just tell the lab that you
shot it correctly! �Be absolutely sure that they are aware

I have used are w/ D76 1:1 at 70deg for around 8 to 10 minutes
for small tank development.

the H2 has no meter, so the asa dial is for "reminder
purposes only", if it even has one- I'd have to check.
I use the D76 1:1 for about 9min at ~70deg. It's been
some time since I shot any - Aaron is "da man" for development
and processing issues, IMHO. After all- it's his profession!
