I want to use Rodinal for my first experience in a darkroom

my question:
How must use Rodinal 1.25 for 300 ml water ??

300 ml water + 12 ml Rodinal  OR
288 ml water + 12 ml Rodinal ??????

 Add the two numbers together. 1+25 equals 26. Divide 300/26 and that
equals the amount of Rodinal. 11.5ml. So use 12ml and 288ml of water.

Not that it even makes that much difference; I wouldn't lose any sleep over
this measurement. Black & white processing at this level is pretty damn forgiving.

I was quickly apprised that an "RSS feed" was not, as I had naively
imagined, some new and unspeakable form of sexual debauchery practised
by young persons of dubious morality, but a way of providing news
articles to the cybernetic publishing moguls of the World Wide Wait so
they can fill the airwaves with even more useless drivel.

 True it won't matter here. Even if it did just doing it the same away
every time would be good enough. But knowing the "right" way to handle
dilutions might matter with some other items.

WHY? It's not all that good a developer.

Why?  It's inexpensive, internationally avaialable, the concentrate will
literally keep for years, it produces results some people find visually
appealing, it works with a wide variety of films and can be used at a
broad range of dilutions for different effects.  In medium format,
you're unlikely to notice the grain, though it can be distracting with
fast film in 35 mm.

Sounds like a fine beginner's developer to me.

Heck, I used Dektol for the first roll of film I developed at home (in
about 1970).  With contact prints from 620, who could tell?

Yeah. I use it mainly for sub 200 ISO. and HC-110 and T-Max-developer for
400+ development.
A 50 ISO film (e.g. Ilford Pan-F+) in Rodinal 1+50 is a joy! And other
slower films are also very nice in
Rodinal 1+50. My absolute favourite.

> Sounds like a fine beginner's developer to me.

The best and the cheapest. My first developer. Easy to mix and very
versatile.

Not me. It's way too grainy!

PRECISELY!

Giuseppe:

in 300 ml water add 12ml Rodinal.
