I finally got to process some 4x5 chromes with my JOBO ATL1000. I have to say this little machine is amazing! I used the KODAK 5 liter one shot type kit for chemicals, very easy to use! They give you instructions on how to make smaller batches of chemistry from the concentrates which prolongs shelf life by not having to mix it all at once. My 4x5 chromes look great! So far I have processed only Kodak Ektachrome and AGFA RSXII. I read on the JOBO forum that FujiChrome works out better if processed longer in first developer, any truth to that?
