Since finding APUG, have found myself moving from 35mm/MF to 4x5, 5x7 and most recently 8x10. With the format changes have come the desire to try Alternative Process as well, 1st Ziatypes, now VanDykes and hopefully soon Kallitypes. Question I have is do those that use more than one alternative process have seperate trays, tongs, magic bursh, shot glass etc for each process? Have been advised by people who's opinion I respect that this should be the case and admit that I have not been diligent about doing this, so wondering how bad my technique has been. Plans are to have seperate tools for each process, but then that does add to the expense of each process...while admiting that the price is small and if an item becomes contaminated then it has to be replaced and two sets will be required. As always, Thanks in advance for all your input...this is such a great source of information (and not a bad place to find that other have learned the hard way so the rest of us can try and avoid the same pitfalls...after all there are plenty of pitfalls for all of us to find ).
