Just watched an interesting video on Parodinol

Parodinol

Not thinking of making it but I found the addition of paracetamol interesting and also wondered if it wouldn't raise a few eyebrows if you started ordering it by the kilo.

Any thoughts on this as a developer? What difference does the addition of paracetamol make?

Well, in theory, you'd have fewer darkroom headaches ...

Paracetamol? Pah!
The next video to come up was semi-stand in mint tea. Seemed to work quite well.

PaRodinal is a just one of the several DIY Rodinal substitutes. As you might be aware, p-aminophenol is the developing agent in Rodinal. Instead of using p-aminophenol directly, PaRodinal uses paracetamol (acetaminophen) and breaks it down into p-aminophenol with the help of sodium hydroxide (lye). So the developing agent in PaRodinal is p-aminophenol. As a Rodinal substitute it works as good as any other.

PaRodinal was formulated by Sreenath in 2004 around the time when p-aminophenol was becoming increasingly difficult to source and DIY developers captured the imagination of people. It gained popularity as Paracetamol is ubiquitously available.

Thanks guys. Fascinating chemistry.

I used mint tea successfully in a workshop recently. I usually use a one hour 'stand' with my kitchen concoctions and was surprised how fast this one developed. The brand you use matters A LOT! It was only a 35mm film so does not qualify here (although I did shoot it in a medium format camera ).

Is there anything that won’t develop film?

Same tutor was also using kitchen scraps and there is now lots of info on seaweed and compost! I want something fairly reproduceable for larger format (enough variables alread) so I'm sticking with my local rosemary crop . . . for now.

So, you could take a picture of a Polo mint and develop it in mint tea. Then a melon in melon juice…
A whole new field of creativity opens.

The river Tees. When I was a kid you could develop film in it - or so I was told. Then they cleaned it up a bit.

River Don and River Calder were very similar when I was a kid. Levels of toxicity were such that I'm not sure the film would have survived.
