UPDATE: I posted my very own tea developer recipe here!
After searching the web for information on tea-based film developer and not finding much, except for this rather inspiring forum thread, I decided to just bite the bullet and make my own tea developer based on what little information I had. I didn't have black tea but I did have some orange pekoe, green, peppermint, and pomegranate green teas in my kitchen cupboard so I thought, what the heck, let's get some water in a saucepan, throw some tea bags into it, boil it, mix it with vitamin C and washing soda, and see what happens!
While the teas were steeping, I shot a roll of Fuji Acros 100 around the house with my long-abandoned Chinese medium format SLR camera, the Great Wall DF. If the tea developer didn't work, I wouldn't be too sad because I can always re-shoot the same things all over again some other time if I want to.
While I was busy preparing the film for developing, Troy got home from work and insisted on going grocery shopping. I didn't really want to wait until we got back home to develop the film. Originally, I thought I'd do a 30 or 45-minute development, agitating every 3 or 5 minutes, but since we had to go, I decided to do a 2-hour semi-stand development. I ended up agitating only 3 times in total. Then I washed and fixed as normal and washed again. And then, the moment of truth: did it work? It did! Yaaay!
I did notice the white spots on the negatives when I was hanging it to dry but didn't think much about it until I started scanning and saw the many dark spots on the scans. It was kind of disheartening at first but then it grew on me. The dark spots actually give a vintagey feel to the shots which I find rather endearing. I hope that I'll be able to replicate the effect the next time I decide to develop with tea again, which is going to be soon. I really can't wait to experiment again with different combinations of tea!
If you're interested, there's a couple more pictures from the roll developed in tea (other than the one at the beginning of this post) in this Flickr set.
