Arista.EDU Ultra 100 in HC110 dilution B

[Nicholas Lindan]

Although the data sheet for Arista EDU Ultra 100 4x5/8x10 sheet film says 'NR' for HC110, it seems it can be done. Developing time is short and a bit close to the induction time so results may vary. ASA 100 is optimistic for this film and 25 or 50 may be more appropriate depending on how you like your deep shadow detail.

Test results One sheet of film, cut in two
Left side: HC110 B, 4 min, 20C, tray, continuous agitation
Right side: D76 1:1, 9 min, 20C, tray, continuous agitation

Not much of a subject matter, but it was sure to be a negative I would never regret cutting in two.

HC110 time was found by WAG.

Just goes to show the magic of BW... so long as developer touches the silver for some reasonable amount of time, you'll get an image.

Those times are rather short... I wonder if pushing the film and then pulling development would make it easier to be more consistent with longer times? If it's that large of a sheet, I wouldn't think the increase in grain would matter that much, would it?

I actually kind of like it.

Does the agitation regime affect the induction time, or is induction time more of a fundamental constant of the film? What I'm thinking with this question is that continuous agitation might prevent 4 minutes from being a "stupidly short" development time as it is with the intermittent-agitation regime that's usual for rollfilm.

Thanks for the post. I recently started shooting this film in 4x5 (ISO 100). I developed them in HC-110 dilution H for 8 minutes and my negatives were coming out pretty thin. I thought that I was either doing something wrong with the developer or the film was actually rated at a lower speed. After some more research and testing, it looks like ISO 100 definitely is generous...with my box at least. Glad to know that someone else thinks the same thing. I'll shoot it a stop or two under 100 from now on.

As for your image, I find it to be a very subtle difference and it's hard to tell from the photo but I think I do like it in HC-110 better. Maybe I'll try it in D76 one of these days just to see how it comes out.

Coming up on Worldwide Pinhole day I shot some of this film in 4x5 and used HC110 Dilution E (1+47) at the D-76 times (6 to 7 minutes) and was pretty happy with the outcome. Since I use HC110 as a one shot, I try to avoid the higher concentrations anyway.

I shoot 4x5 Arista.EDU 100 and develop in HC-110 dil. H in a Beseler or Unicolor drum with motor fairly regularly. The MDC gives a time of 10:00, but I shorten that by around 10%. I've had good results exposing at both ASA 50 and 100.
