I was given a can of Kodak Microdol-X, but I dont know if it is still
useable. The CAT#501 0780 is to make 5 Litres of stock solution. On the

The condition of the can seems to be good, but its the condition of the

I'm sure I came across an article about a staining metol based developer.
The trick is NOT to bleach out the stain with an acid fix. I've now got my
supply of Formulary TF-4 in, but I've lost track of my reference. Possibly a
gainer article? Can anyone help?

It's come to this. I need to polish an old glass carrier (Leitz Focomat IIa)
to get rid of some fine 'something' that's spotted it. This is my only

know, for example, if I have found the right time of exposition to

I know this will be very basic; but.....
I just bought a Seal 120 press and cleaned it up.  Got Promount tissue and
release paper.
Washed some Ilford MGIV Glossy prints.

After ten years without a darkroom, I just finished setting up a new one
in the basement. I've done mainly 35 mm in the past, but I'm planning do
a lot of medium format with the new setup.
