Rodinal / Adonal Developer

In this post, I am collecting my experiences developing black and white film with Rodinal developer. (Now sold as Adox Adonal.) I have a little notebook with all of this information that would be a huge pain to lose, so I’m transcribing those notes here and adding more as I learn.

For the basics, the wiki post is a great place to start… (Be sure to check those external links!)

Digital Truth has a massive chart of development times for Rodinal with all kinds of film as well as the Rodinal product leaflet. You can find the Adonal Material Safety Data Sheet (the stuff I use) at the Adox.de site. I ordered my 500ml bottle of Adonal from FreestylePhoto in the USA. In Europe, you can order from SilverPrint.

Mouse Cam – Connectix QuickCam Mods

I finally managed to track down a used Connectix black and white webcam on E-bay, and after a few weeks I was testing and tweaking to my heart’s content.

I quickly realized I was going to need some sort of box to put this thing in so it would attach to the scope more easily.

After rummaging around some old computer equipment at the office I came across an old IBM PS/2 mouse. Hey, the dimensions were right… Its really light, the hole at the bottom seemed the right size… Well why the heck not??
