    Thanks for the info, do you know what these things are called? It should help with the search. I looked for vacuum frames with no results. I also looked for ‘uv exposure unit’ but these don’t seem to...

    Thanks for the replies, I looked at vacuum frames and they do seem like the way forward for my purposes, just need to find one now. I’m based in the Uk, are the Nuarc ones harder to find here? I had...

    Re: Decoding Jobo Gear.

    The tubes I’m using are all labelled and have the recognisable Jobo font.

    Do you have any experience with the volumes of chemistry for processing prints?

    Re: Is it possible to pre wash photo paper?

    Thanks for the info, I hadn’t actually heard of this as a process and it might be a good tactic, can I ask how I would ensure even development on the paper with a sponge?

    Thanks.

    Re: Is it possible to pre wash photo paper?

    Thanks for your response. Good to hear that pre washing the prints is possible, I suspect it will be required with the fb paper as it’s more absorbent than rc.

    I always use several water baths...

    Great thanks, do you know how long the undiluted solution would last when opened, if stored in a bottle with the air taken out?
  18. Re: The new Ektachrome E100, Tetenal E6 and Jobo

    Thanks for the info. So would I need to make up the chemicals in small batches as I go or do you have to make up the total kit and store it mixed?
