Clip Test ; Part 2.

[Mike Kennedy]

I have ben using this method to check the usability of my fixer and its working out fine. Just wondering if I can use any B&W film to do this test or does if have to be the same film I am fixing?
The reason for my question is that a friend gave me some T-max 100 (bulk) that I really don,t like it. Thought that I might use this for my clip tests as I sometimes forget to save the leader from the soon to be processed cartridge.

Thanks,
Mike

I am sure there will be plenty of informative replies on this but I noted that in one book about B&W processing, there was mention of Tmax requiring a lot longer a fix time than other films. So it maybe that in testing fixer for T max you should use a T max leader.

If you're just checking the exhaustion of the fixer, any film will do as long as it's the *same* film you used to establish the base clearing time.

If you're testing to determine fixing time, obviously you should use the film you'll be fixing, since different films take different times to clear.

Sort of figured as much. I just have to remember to do the clip test BEFORE I load my film into the tank. My film changing room has odds & sods of film all over the floor. Hey, maybe I should sweep it out. Make a note to self! Naw. I,ll do it NOW!

Thanks for the replies,
Mike

Generally speaking if Tmax films clear in X minutes, any other film will also. I think it's the high iodide content that makes it so.
