I have been doing my own developing for a couple of years now. I am learning more than ever through experimentation, practical application and reading. I find I go through a lot of 'the more I learn the less I know'.
This is the internet and I think it's very often dangerous. The opinions and geekery about subject matter lead me to believe that there are more people with Asperger's than I thought.
There are so many techniques out there that it just becomes a mine-field. Standard developing vs stand developing, this developer vs that developer, this tank vs that tank, everything vs everything to the nth degree.
Do some of these things really make a difference. What got me going was that I started reading about stand developing, why do it, what are the pros, the cons? etc. I try new developers from time to time and I try different films. I like the science, but I like the picture and I just want to get into the darkroom with a good enough negative and print a picture. I find it's better for me to follow a standard (generally the manufacturer's and then tweak it to my situation). Use the same set of products and try and try again until I get the results I want and then try to continue to get those results.
By results I mean to a good enough standard for me to work with in a darkroom and produce a good enough picture that pleases me and others.
Surely what matters is what you take into the darkroom and print on paper. It's a craft, a science, yes, but can we become bogged down in microscopic details?
Can we easily become bogged down in geekery or are there really superior results to be found in engineering things to the nth degree?
You've asked a question that you already know (justifiably) the answer to. You've struck the mother lode (APUG) of photographic geekdom!
