As I am putting my notes together to produce “The Photographers Coffee Break”, I decided to do a quick calculation on the actual cost for Caffenol C Developer as sourced from my local grocery store… $1.00 per roll if you use distilled water… .75¢ per roll if you use tap water… not bad at all!
I am leaving for New Orleans later today so for the next few days posts here on FR will come from my ipod Touch.

I look forward to see this as I wish to begin and try this.
Travel SAFE most of all.

Are you referring to 35mm or 120 film?
I always mix 500ml so this was based on this amount which is perfect for 120.
Hello Stephen,
As everything has been said about your thoughts/blog/photographs…I am highly awe, WOW !I just discovered your site and magical Caffenol, that is one of the best joys in my day, sweet : )
May you help me about developping 35mm in a JOBO 1520 (?)
It is written on tank as follows:
Rotation: 240 ml
Inversion: 485 ml
What shoud I use for one 35mm film ? Next, I think I understood about caffenol, I should divise each element by 4 (?) But, the ‘standard’ dev time wil remain the same ?
Admit, preparing of 250ml Caffenol developper CCM. That would give me:
13,5g washing soda/ml
4g Vitamin C/ml
10f of instant coffee/ml
..and for CCL 0,25g Potassium Bromide/ml
I hope my explanation seems good, my english too : ) looking forward your book which sounds really, really relevant, for sure!!!
Thank you Stephen, faithfully!!!
Mathieu
