Opinion sought: Omega 45D

If you think cardboard isn't sturdy enough, there's always tempered hardboard (aka Masonite). I was thinking of polycarb with a black filler if I can find one that works (takes to being cut/drilled well). |

Is there a tank system to do E-6 at this size?. I found a DIY system: http://www.largeformatphotography.info/unicolor/ that will do 2 sheets at a time. Not a process I'd like to do, however. Yes. I have done both E-6 and C-41 in a JOBO 2521 tank (for 6 sheets) and a 2551 (for 12 sheets) in a JOBO CPE-2 processor. I use their 2509n reels. You probably want their loader to load the film on the reels, although I am told it can be done without. -- .~.

Styrene or PVC would also work. Weapons of choice would be an ordinary hole saw of the right size or a fly cutter for larger holes. Enlarge if necessary with a wood rasp and voila! -- Found--the gene that causes belief in genetic determinism |

There are basically three methods of developing sheet film, whether B&W, color neg, or transparency. 1. Tray processing. Must be done in darkness and temp control can be difficult 2. Tank processing where the film is around the perimeter of the tank. Uses small amount of chemicals, but can only handle a couple pieces of film at a time 3. Tank processing where the film is held in some sort of holder and covered with chems. Uses considerably more chems, but can handle perhaps a dozen sheets at a time. Personnally, I use an old Unicolor drum (#2 above) that can handle one 8x10, or two 5x7, or four 4x5's As for chemicals, generally the developer has the shortest life. I use Trebla brand for c-41 color negative film. It's sized to make five liters, but it can be mixed in smaller quantities. Trebla does make e-6; I'm not familiar with it, but I would guess it can also be mixed in small quantities. |

It is sometimes useful to have a lens, that is capable of a lot of movement, mounted off center. Oy! there are so many movements I hardly think I want to add another... |
