H-e-l-p !!!
I'd be grateful for some advice if folks area able to help.
I've got some Washi W film, which the maker states is best developed in Tetenal-Eukobrom in a tray under a safe light in a 1+1 solution for 3 minutes at 20 deg. C. This is the only developer the spec sheet mentions that will allow exposure at ISO 25, which is what I need to do.
I have bought, in error, some Tetenal-Eukobrom AC, which is different!
I understand that the difference is that the standard version uses hydroquinone , like most developers and the AC version uses isoascorbate instead (vitamin C).
My question is, can I just substitute one for the other without a problem or will I have to make some other adjustment? I am not a chemist by any means, so I just don't know!
Any clues folks?
Help would be much appreciated.
Thanks
