To reply to the questions in the last 3 posts. The film was rated at the standard 200 ISO. Taken with a Nikon F100. The processing times are as shown in the table I sent at the top part of the previous page,
Tetenal chemicals last as long as almost any others provided they are stored properly. The 1st developer seems to be the only one that 'goes off' so I squeeze the bottles to get rid of as much of the air as possible then screw on the cap tightly but place the bottle upside down in the box. This seems to preserve the contents better than just standing it upright- don't ask me why, 'cos I don't know, but it does. I have just finished one kit with about 10cc's of developer remaining and this is still light straw coloured. When I start my next kit I will not use this left over bit anyway.
I have been thinking about getting small dark brown glass bottles from my Pharmacy (50CC) to decant the 1st developer into because glass is a better preservative. Plastics are not fully impermeable against Oxygen.
(The placing the bottles upside down was done really as a test because of the results I get with part used tins of paint. Treated this way they never form a skin over the remaining usable contents. A wet contact with the seal seems to stop ingress of any air. I don't know if this is correct, but I only go on what I find and it seems to work.)
