Developing Ilford HP5+

Published by Bill on (Updated: )

This note isn’t intended to be a guide on how to develop film at home. This is a collection of tips and notes from my development experience.

Tip: Download the Massive Dev Chart Timer App (£8.99).
The app will help lookup and calculate developer times and mix ratios. But the most valuable feature is the timer. I kept second guessing myself on everything until I started using the timer. With the timer I have the confidence to develop a tank and clean up as I go.
