Finally this time using film (Fuji Velvia 100) worked with Caffenol!
I just followed the previous process. But this time I considered ISO as 50 value and well it worked very well!!!
The only thing I`ve to try next time it to reduce the time inside the coffee mix from 9 to 8 mins.
Probably the film will be more lighter. I want also to try to insert salt.
The camera I used is my great Mamiya 645 super and the photos were taken last week with my friend Rio.
Enjoy the photos and Stay Click!
