R3 (and other monobaths) are so easy, cheap, and virtually instant

I was just playing with a Pentax 67 and the 105mm f2.4 lens the other day with some KODAK 400TX and tossed it in the R3 monobath for 10 minutes. Afterward it got washed in too-hot water, so it reticulated a bit.

What could be easier, and cheaper, than this? A digi? You get a 6X7 negative that takes 10 minutes (and costs about 50 cents). I would like those who are concerned about costs to show me their results with this process.

Yeah - you heard the man. Get off your asses, turn off the computer, and go shoot some film.

So I did today. Shot some collr 4x5 and some black and white. I have yet to try the monobath.

easier or faster? my R4 in 4 minutes. Cheaper? Rodinal at 1+100? Sorry, I tease. I am pleased to see the P67 performing in new hands. You must let it grace some candid skin, to show you how it treats beauty.

That is exactly what is needed, and steps are being taken so we have a more varied subject matter for New55 images.

I tried out the monobath. On my blog I posted some results. darkroomninja.blogspot.com

Works awesome but I have to finetune the workflow a bit.

Peter looks great to me. Keep it coming!

Thanks. In a few days I will develop two 4x5 negs. Hopefully the will look better. The ones I scanned look a bit not so black and white like I am used to. Tomorrow I'll post a photo on my blog to see if I can show you what i mean.

I have never gotten around to do the 4x5's. However recently I started wondering if I could make a monobath for paper as well? Any idaes if paper developer could be used in the formula? I tried a search on the site but i did'nt come up with a result. (I'm not good at looking stuf up nyway so it is propably me :-) )

I want to start to play around with Ilford's positive paper. That started me thinking about this.

Bob Crowley said...

Peter, Yes, I use R3 on paper and it works very well.

It does not work well with Ilford's Direct Positive paper, but I have a formula that does work with that paper. If I have time in the next few weeks I will try to fine tune it and show the results, and provide the details.

The Direct Positive paper is a lot of fun, and it is not very slow! With a fast lens we have 5 second exposures under bright room lights.

I had never tried R3 on 35mm before this week, and I also can see the sprocket holes. I think R3 is not great for 35mm. Another reason is that grain is not quite as fine with R3 as some fine grain developers. I almost never shoot black and white 35mm, just 120.

Peter said...

Thanks for the answer. When you use R3 is that with the hc110? I'll have an experiment with it as well. If I can get myself to clearout my darkroom a little.

I plan on using the positive paper in pinhole camera's. At college I'm planning on making a pinhole camera that can take 4x5 filmholders.

Good to know that monobath has a problem with the sprocketholes. I'll give 120 film a go as wel. Time for more experimenting then.
