120 Ultrafine Xtreme 100 in Rodinal 1:100

120 Ultrafine Xtreme 100 in Rodinal 1:100

The Digitaltruth Massive Dev Chart has no entry for 120 Ultrafine Xtreme 100 developed in Rodinal 1:100, so I decided to give it a go. I used 18 minutes as a starting point, with a one-minute presoak. Developing time was actually 15:52, adjusted for temperature. See more below.

  1. Yes
I also used a reduced agitation scheme: continuous for the first 30 seconds, twice every five minutes after that. The image could stand a bit of burning in the sign, I think. It's also best viewed in the "Lightbox" mode. In another version, I used the "Dehaze" slider in ACR to good advantage.
 
Ken, at 1:100 how much Rodinal did you use? I ask this as the minimum stated quantity for success does seem to vary a bit but everything looks fine here.

Thanks
 
@pentaxuser 5 ml Rodinal (I understand this is the minimum recommended amount), and 495 ml distilled water in a plastic Paterson tank. Thanks for saying it looks fine, although to my eye the development "tamed" the Ultrafine film a bit -- I'll develop another roll soon using D-76 and a less relaxed agitation scheme to see, but I'm used to Ultrafine being bright and even "edgy." As I say, I'm not sure if my perception here is off, but I'll report on the test.
 
Thanks for the reply Ken. It is always difficult to judge a negative from a positive scan and I have no knowledge of scanning being a neg to darkroom print person but while there is evidence that 6ml is regarded as the minimum, your 5ml seems to have worked OK.
 
Mamiya came out with several iterations of the 645, do you have experience with any other versions and which is the best if that's a thing.
 
@PhotoBob I have a 645 1000s. That's the only version I've owned. In the eighties, I really wanted a Mamiya but couldn't justify the expense (photography was a hobby). When I returned to film photography several years ago, the first thing I did was check on E-bay. The camera I have cost $300 and included a 150mm lens. Recently I bought a 120mm lens, for about $200. I also bought a split-ring focus screen because I was having trouble focusing the thing, even with my glasses on. Now, as I've noted elsewhere, I wear 1.5+ reading glasses to focus my camera. Whatever works! Thanks for asking about my camera.
