6. Preparing chemicals Chemicals – Developer – 600 mls total 25mls Rodinal 575 mls water @ 20 degrees – Stop bath 600 mls water @ 20 degrees – Fixing agent – 600 mls total 60 mls Fixer 540 mls water @ 20 degrees – Hypo clearing agent (also called Hypo eliminator)

7. Developing procedure Pour developer into tank – temperature control is important (between20 – 21 degrees) Agitate using timer and then pour developer out Pour stop bath into tank – chemical or water Pour a fixing agent into empty tank – at this point safe to take lid off your tank – leave film for recommended time Rinse film with hypo clearing agent or water Hang the film (don’t touch negative surface) Leave for 2 hours to dry Clean tank
