Rollei Digibase RA4

[putrofedon]

Hi, Im going to begin with RA4 and I would like to know if someone has tried the digibase ra4 at room temperature. The instructions are clear about 38 degrees, but maybe someone knows better...

Thank you.

On an other thread here on APUG there is al lot of information about the ins en outs Rollei Digibase RA4.

Welcome to APUG

You are right. I have been a little bit rude. Sorry, and hello to all.



And @hka: thank you. I've been searching but didn't find something about digibase ra4 at room temperature. I'll keep searching in the forum.

EDIT : in http://www.apug.org/forums/forum40/137842-ra4-re-use-chemistry.html there is some information.

I might be wrong but I think that Harry(hka) might be thinking of the very long thread on Digibase C41 and not RA4. I can't recall a thread on Digibase RA4.

What I can say is that if Kodak RA4 is fine at room temperature and it is, then I see no reason why Digibase RA4 should not be OK also

I use the 1 litre kit available at Maco at room temperature. 2,5 minutes for dev, 2 minutes for blix. I think I just made those times up... Things look good, but I am a beginner. I use about 10-15 ml of each solution in a drum, one-shot of course.

edit: Looking for a roller base, it's not too fun rolling that drum for 5 minutes..

Thanks to all.

On the thread I mentioned, RPC has said:

I use trays, which I vastly prefer over drums, at room temperature (68-72F) for two minutes and never have problems with repeatability. I found that at high temperatures, (95-100F) there was much less headroom time-wise than at room temps and a greater potential for inconsistency.

Between 2 minutes and 2,5 minutes. I'm going to try it today and I'll see.

I use Kodak RA-RT Developer Replenisher. Being a replenisher, it will be more concentrated than regular developer. Therefore your developer may not work the same at room temperature if it is regular developer and not replenisher.

I thought you used Digibase. My fault.

Anyway, yesterday I tried 2 minutes at 22 degrees, and it was ok. The same for the bleachfix, but more flexible in time.

Thanks pentaxuser your right it was indeed the C41 thread. Sorry about the confusion.

10 to 15ml can't possibly cover 8x10 in a drum (and I know of no smaller drums). Even so, I think it's too little solution to fully develop 8x10. Maybe you're doing something different.

Most RA-4 requires one minute at 94F, two to three minutes at "room temperature" (70 to 75F). So those times seem right.

Check eBay for a motor base. I saw one come up for around $40 recently. Or post in the WTB ads here.

Like bvy I can only assume that either cl3mens has got confused about the amount needed -my Jobo drum says 50ml for a 8x10 and I cannot work out how 10-15 mls could possibly be enough in any drum and yet presumably he has seen no problem with his prints. Maybe he means he dumps 10-15 mls per print and this is the replenishment amount each print rather than the amount needed for each print

I hope cl3mens clarifies this for us

I am using the same Maco Digibase RA4 kit, using it at about 35°C (instructions say 35-38°C) with a camping heater under my Paterson Thermodrum, results are repeatable in color, the important thing is to keep the same temperature.
