Covid Caffenol Chronicles

My Caffenol Experimentations during the Covid Quarantine

My first attempt at Caffenol, negs too thin. ---- My first attempt! 06.04.2020 I followed this recipe from the Caffenol Bible: Here is the Caffenol CM-RS recipe I use: 500 mls tap water @ 70 deg. F. 4 tsp. arm and hammer washing soda (not baking soda) 1&1/2 tsp vitamin C powder 1/2 tsp iodized salt (mortons) 5 rounded tsp cheap instant coffee (the cheaper the better and not decaffeinated) Mix in that order and let sit for 5 minutes. Pre-soakfilm for 5 min in 70 deg. tap water. Develop for 11 minutes - agitate for the first 30 sec.then a couple inversions every 30 sec.till done. Works best with 100 iso or slower film! I used Arm & Hammer laundry detergent (not simply washing soda though it does contain washing soda.) My washing soda I left at school was MIA- ordered more today. Plasset Premiere instant coffee from Mexico from my local dollar store Film used: Ultrafine/Kentmere 100 Results: about three stops underdeveloped (thin) Remarks: I used only 4 teaspoons coffee (accidentally), there was alot of foam. Also it was a cold day and though the film started at 70/21 degrees, and I think the temp dropped. More importantly I didn’t have the washing soda and used a detergent that I thought was primarily made of washing soda
