Re: [APML] TP woes

["Brian Larmay" <brileau@earthlink.net>]

Just out of curiosity...

What are you shooting at?
Low density areas?
Might you be overexposing by chance?
Im sure youve questioned and exhausted every possibility you can think of.

Maybe a leak in the camera?
How are you agitating during development?
5 mins seems short...last strip I developed at 5 mins came out almost clear
and that was a recent Lumicon roll which I bought 3 weeks ago.
Seems to be working fine for me from that time period

I also usually go for about 5 mins with regular fixer....no stop bath.

I wish you the best in figuring this out.

And heres a question for the pros...
Does soft water and hard water make a differance somehow in developing?
Distilled?

Good fortune,
Brian
