Make your own developer ?
-
Remember recently coming across a thread on some other site about someone making their own developer
out of coffee of all things. Maybe I was imagining it, maybe not :)Anyhow, just wondering if anyone here makes their own either from the raw ‘regular’ chemicals or from some
other bizarre concoction ?yea, google Caffenol or goto http://www.apug.org and find the articles section

Thats it, the apug site. Have you tried it yourself ?
Not yet, are you going to have a go?
I’m tempted for sure :) Need to practise developing a bit more film thought I think :)
the results might be a bit unpredictable and you might have to experiment with development times/temps. i’m a bit too lazy for that and hate developing, love printing though.
i also use a rotary processor [jobo cpe2] and not all developers like the constant agitation of a rotary tankFintan wrote:

If you’ve got a good negative to work from, it makes printing so much easier. A rotary processor sounds great, but the one drawback of it is that you can’t get a compensation effect like you can with regular hand developing. Compensation is achieved by extending the periods between agitation, allowing the shadows to develop fully without blocking up the highlights.
As far as developing with coffee is concerned, I can’t say I’ve ever tried it.

Thanks for the lesson Thorsten, I know what I’m doing.
I wasn’t suggesting that you don’t! Apologies if that’s the impression I gave. I just thought I’d mention the benefits of tank- or tray processing for the benefit of other users new to film processing. Rotary drum processing does of course have enormous benefits in terms of consistency, etc. IMHO, many users new to black and white photography don’t appreciate the value of doing your own developing, so if an opportunity presents itself to drive home the importance of doing your own developing, I do so.
Apologies again for any offence caused. I guess I could have chosen my words better. Lesson learned – don’t post late at night when I’m half asleep!

As well as achieving edge effects, or acutance, or sharpening, as its now rather prosaically known-
