Cheapest way to make a paper developer DIY

[ruilourosa]

Hello

Before someone starts saying that dektol or fomadol or multigrade is best, i have no interest in commercial pre made solutions. I usually make some variations of d-72 either substituting hidroquinone by Vit C or also metol by phenidone.

so:

Vitamin c is quite cheap
Sodium carbonate also
Potassium Bromide so so but OK

but...
phenidone or metol are quite expensive here in portugal!

Is there any way to substitute any of these for a easely found product?

pyro, catechol and amidol are off because they are even more expensive...

any ideas or is it an unobtanium...


THanks

I'd bite the bullet and buy some Phenidone, it keeps well and you don't need much per litre of stock developer solution.

I´ve bited that bullet. I just want to know if there are any feasible solution. Specially if could be bought cheap and in a drugstore or supermarket!

I have looked around, people are using acetaminophen and coffee, mainly for film, but for paper the choices are a bit off

Thanks

Maybe you can order abroad. For instance, disactis, in France. Their prices are very competitive, and the quality of their products is very good.

I imagine that you looked into Caffenol-C.

I've made it twice just to test it and it does work. However I haven't spent the time needed to perfect it.

In my case I ground up Borax and Vitamin C tablets together in a food processor, both being easy to obtain in the small town I'm in. Then mixed it with cheap instant coffee.

When I have the time I want to experiment with it some more.

There isn't really a way around using either metol or Phenidone (or derivatives) in a general purpose print developer.

Standard paper developers usually require metol or phenidone, hydroquinone, sodium sulfite, sodium carbonate, and potassium bromide... With those chemicals, you can make MANY different formulas!!! The cheapest way (in the long run) is to buy a pound of the metol and hydroquinone, and 5 lbs of the sulfite/carbonate, and 100 gms of the phenidone + bromide, and these will last you a long time, and end up costing you VERY little for each batch mixed... But you will need a scale, but you will have saved MUCH money, and have a range of developers to choose from...

Acetominophen developer, without coffee, can be used for prints. The amount of developer to use is about twice as much as for film. There are several recipes for Paracetamol archived here at the forum.

I have some years of experience in making photo solutions, from developers all through photo emulsions. But since there have been some evolutions since i start doing things (like parodinal and caffenol c) i was wondering if could be a new thing.

The cheap quality of the developer is not for me is more to a school i work to.


CHeers an thanks

There is a ebay seller in the Ukraine who sells low volumes of Metol, I ordered 90g from him for about £8 delivered. The first lot was lost at customs but second has arrived.
