Getting ready to develop film at home just got a little faster if you track your chemical use and expiration with Chem Log.
Analog.Cafe v3.30.84 adds a handy Dilution Calculator button to the Film Log app (analog.cafe/app/film-log) to help figure out precise chemical ratios and shows all selected chemicals’ stats/reuse calculators front-and-center when you need them.
Though you still should test your chemicals (here’s how: analog.cafe/r/how-to-test-…), Chem Log (a plugin for the Film Log app) can help you avoid issues by giving a quick reference to mix dates. If something’s very old, you’ll know to avoid using that bottle.
Chem Log also helps extend the life of your C-41 chemicals by showing you adjusted development times based on the volume of your developer and the number of rolls that went through it. I’ve used this app to extend the life of my 1L (quart) Arista kit to 28 rolls — 20 beyond the recommended total — which added up to about $1/roll — without any significant issues in colour or grain.

More app updates:
#film Q, a web app for inverting film negatives in the cloud, received a small bug fix. Previously, switching the “Autostart” setting ON would undo the “Fix Base Fog” mode. That could be annoying for anyone attempting to fix colour shifts on positive scans in batches, but it’s now fixed.
New #video🍿 and podcast comment tags now feature a special design to make viewing and listening to analogue photography content easier. I’ve also revamped how the comments appear and expanded the maximum amount of characters per comment to 4,000.
Please reply to this comment or get in touch if you have any feedback or problems using the Analog.Cafe website!
