  1. Re: Use of X-ray film: technical discussion with example images

    I put four layers of gelatin on her face, in thin coats.

  4. Re: Use of X-ray film: technical discussion with example images

    I use the SP445. The marks it leaves at the edges of my negatives are terrible. Tray dev would always leave scratches everywhere. I'd prefer to use something like the Jobo 3010. Currently I don't...

  6. Anyone ever had problems with Epson V700 producing blue streaks, blotches?

    I'm getting something like this, when I do the preview: 208501
    Scans are showing up the same way. I seem to be able to get away with a couple per session without this problem, and then this crops up...

    Here's some more work. This is all Fujifilm x-ray, 7 1/2 minutes in Rodinal with constant agitation.

  10. Issues with faint splotches on negatives when home-developing

    206105206106

    I develop at home with an SP445 tank and Rodinal. Before hanging the film, I do a final wash and quick soak in distilled water. Throughout development, agitation is even and vigorous....

  13. Re: Use of X-ray film: technical discussion with example images

    Okay, so I have my hands on some UM-MA. Has anyone here worked with this film before? I'm going to start testing both dev and exposure, then will report back. To begin, I will develop it as I did...

    Here are the two spectral sensitivity graphs side-by-side.
  15. Re: Use of X-ray film: technical discussion with example images

    As for the wait at ZZ, I called them and specifically asked about this film. They told me that the wait time posted on their site was inaccurately long.
  16. Re: Use of X-ray film: technical discussion with example images

    I'm happy to say that you're incorrect. It's on the datasheet.

    I also found a paper where B/RA and UM-MA are directly compared (https://core.ac.uk/download/pdf/12529443.pdf), which...
  17. Re: Use of X-ray film: technical discussion with example images

    If I recall correctly from the datasheet I found, it does. ZZ Medical sells it, only by the case.
  18. Re: Use of X-ray film: technical discussion with example images

    It really does seem to depend. I've looked at the spectral sensitivity charts for Ektascan B/RA and UM-MA (a supposedly green-sensitive mammography film), and both are almost identical across the...
  19. Re: Use of X-ray film: technical discussion with example images

    Is ADM MAMO the same as UM-MA? I'm considering buying some UM-MA.
  20. Re: Use of X-ray film: technical discussion with example images

    I have sad news: Carestream Ektascan B/RA has been discontinued. Does anyone know of any other single-emulsion films available? Or does anyone have any leftover stock they're not using? I'd come to...

    Here's a shot at 1/8s and f/11 under some lamps. Carestream EB/RA developed for 7m30s in Rodinal.
  22. Re: Film Group-Buy, Central-Eastern Canada (Carestream EB-RA x-ray film)

    It's the same film, Goldman. Whether you order it from Carestream Canada, or ZZ Medical, if you're ordering EB/RA, you're getting EB/RA. I didn't know you could ask for normal post, but assuming that...
  23. Re: Film Group-Buy, Central-Eastern Canada (Carestream EB-RA x-ray film)

    ZZ Medical charges 97$ USD, which comes out to 127.75 CAD, plus the shipping fees. I've ordered from ZZ Medical before, and I know from experience that these fees work out to being 40$+ (About 30$...
  24. Film Group-Buy, Central-Eastern Canada (Carestream EB-RA x-ray film)

    Hey guys, I'm looking to do a group purchase of x-ray film in Central-Eastern Canada. Due to declining sales, Carestream will only sell EB-RA x-ray film by the case now, which constitutes 4 boxes of...

    Re: Focus Shift For Infra-Red

    For 4x5 that would quickly become prohibitively expensive.

    Here's another example of the sort of fine focus I can achieve when stopping down on 35mm (and when all the unknown variables that I am trying to deduce go right).

    4x5 is even more...

    Re: Focus Shift For Infra-Red

    Gary, I'm talking about shooting in the UV, which I presume is the opposite from the technique for shooting IR. Thanks reddesert, I had no idea about the split image. I can post some examples of the...

    Re: Focus Shift For Infra-Red

    So stopping down should work, because I need to compensate by focusing the image as if it was further away, since technically it is focused "too close" when focused in the visible range?

    I just...

    Re: Focus Shift For Infra-Red

    I'm back, years later, struggling with focus compensation for UV. I'm supposed to be focusing as if the subject is slightly further away from the camera, right? I'm using an enlarger lens, which...
  30. Re: Use of X-ray film: technical discussion with example images

    I'm back at shooting UV with it because I still have the, what, five year old box left. When doing experimental stuff like this, I don't want to waste my Fomapan or my HP5 bulk purchase leftovers for...
  31. Re: Use of X-ray film: technical discussion with example images

    Ravenranger, is this one of the double-sided emulsion films?

    On an unrelated note, what are people's experiences like stand-developing x-ray with rodinal? I've got some EB/RA to use.
  32. Re: Super Angulon 47mm f/5.6 XL not screwing into Copal 0 shutter properly

    Right now Ed, I can’t see any way of popping off that ring without dismantling the whole shutter, which is something I am hesitant to do.
  33. Re: Super Angulon 47mm f/5.6 XL not screwing into Copal 0 shutter properly

    Yeah, Ed, the front guard ring on yours looks slightly different from my own.

    So there is a significant difference between the barrels, which explains why one does not screw in all the way.

    I checked the threads, and they're fine.

    I've included a...
  35. Re: Super Angulon 47mm f/5.6 XL not screwing into Copal 0 shutter properly

    It was the same one that I received with a 58mm Super Angulon XL. I figured that since they were so close in focal length, and shared a shutter size, the shutter would be interchangeable.
  36. Re: Super Angulon 47mm f/5.6 XL not screwing into Copal 0 shutter properly

    Thanks Bernice. It must be a plastic dress ring. This is not the original shutter. I only had the cells, separate. I have a shutter that is not suited to the 47mm XL. That’s too bad.

    I have a...
  37. Re: Super Angulon 47mm f/5.6 XL not screwing into Copal 0 shutter properly

    Hm, that is troublesome. I suppose that means I would have to purchase another shutter?

    Domaz, is it not the internal, silver, ridged ring that holds it together? I watched disassembly videos and...
  38. Re: Super Angulon 47mm f/5.6 XL not screwing into Copal 0 shutter properly

    It has notches on the inside of this ring, and if you push them, it will spin independently of the rest of the assembly (although it will make a brutal squeaking noise).
  39. Super Angulon 47mm f/5.6 XL not screwing into Copal 0 shutter properly

    When I screw in the lens' front element into the front of the Copal 0 shutter, it feels like it does not screw in all the way. The width of the barrel seems to be catching and stopping itself from...
  40. Re: Using Jobo 2500 Tank on an Ilford spindle motor base

    Phil:

    I've thought about this. The old Beseler motor base that was in our communal dark room caused the same issue. I've made a small foam girdle for the tank in order to allow it to spin on a...
