Adox Adotol

[Ernst-Jan]

I acquired an enlarger and hope soon to start with printing. Adotol look like a good option at a good price.
But neither on the website of Fotoimpex nor on Adox.de I see development times for this product.

I am going to use with Fomaspeed Variant 311 paper if that matters.

I would use what I could easily find/purchase. In my case it's Ilford MG... or you could mix from scratch. I do that sometimes, too.

With paper developers, 2 mins for FB is usually a fair starting point, 1-2 mins for RC. It doesn't take long to do a few tests (1 min, 2 mins, 3 mins developing time) & see where a good black has appeared by. You can refine this later if you need to.

I use Bromophen. 2 minutes at 20°C is pretty standard for me. 90 seconds for some. Watch the temperature, my basement darkroom gets chilled in cooler months.

This page says it's equivalent to Calbe N113:

Post #8 in this thread

suggests three minutes for fiber-based prints in Calbe N113.

I use Adotol Konstant all the time and generally after 2 minutes there is no more visible development. Some RC papers even stop around a minute.

Aha, great, so over developing/developing too long (like film) doesn't exist with paper?

With modern emulsions and most regular paper developers, no - you'd need to get into the 10+ minute range to start getting problems in most cases.

Hello Ernst-Jan,
the general rule for developing silver-halide photo paper is: "Fotopapier wird voll ausentwickelt." As you are from the Netherlands, you are probably understanding this technical term in German .
So the - probably - not so precise translation into English is, "photopaper has to be fully/completely developed (with max. blacks)." It has to be developed to completion, to blacks with maximum density.
As the other members here have already correctly explained, this developing time for completion / max. density in blacks is about 1-2 minutes for most RC papers, and about 2-3 minutes for most fiber based papers (for a developer temperature of 20°C). It is dependant on the type of paper and type of developer used, some react a bit faster, some a bit slower.

Well, overdeveloping can happen if you are developing much too long. Then you will get an increased base fog.

We wish you lots of fun and lots of beautiful prints in your new darkroom!

Selbstverständlich, alles klar
Danke

@Ernst-Jan There's a useful rule of thumb for paper development time. Assume that you have an exposed piece of paper that would give blacks after development. Put it in the developer and count the amount of time it takes for these tones to appear. Multiply this time by 6 and you have your development time for this paper - developer - temperature - exhaustion combination. You can of course exceed this time if you wish, but within reason.

Sometimes known as "factorial development" - using a factor of 6 in this case.
