sidestep: direct positive paper

Hello,

I received a message from Anton, who developed the Harman direct positive paper in Caffenol. Read the french report here: http://www.galerie-photo.com/positif-direct-papier.html

translate.google is very funny, but you will understand the sense.

Confusion

I found this recipe and it's one of the best examples why I only use international standard units:

I do not recommend using this recipe! Does it deserve the name "recipe"?

300ml water with 12 scoops of Instant Coffee
400ml water with 8 scoops of Soda Wash
2 tsp of Powdered Vitamin C

Developed @ 70 C for 9 Minutes
Kodak Stop bath for 1 minute
Kodak Fixer for 5 minutes
10 minute water wash.

He mixes scoops and teaspoons (tsp). What the heck is a scoop? And he mixes scoops and teaspoons, ha??? Does he boil his films in 70 °C(elsius) hot coffee, or does he mean 70 °F(ahrenheit)? Other authors use tablespoons, knife tips, taels (???) and everything else you can imagine.

In anglo-american cultures 1 teaspoon is defined as 5 ml (milliliter). But that is not obvious for the rest of the world. What, if my teaspoon is 3 ml and yours is 8 ml? It makes a huge difference and will spoil the cake. If using 35 or 45 grams instead of recommended 40 grams because of unprecise measuring probably will not spoil the cake. 1 gram is 1 gram, whether you sit in NYC, Rio de Janeira, Paris, Capetown, Beijng or Tasmania.

Everybody uses measuring mugs for fluids, so why not at least use them for volumetric measuring instead of teaspoons and others? The rest of the world will be grateful. For some more precision buy a weight scale. They aren't expensive anymore. Mine did coast 10 Eur.

Beeing creative is cool. Measuring with obscure methods isn't creative at all if you do it all the way wrong. That's totally un-cool. Please understand that I don't want to blame or offend anybody, but also pleeeease, hear my prayings.....and be gentle with comments. Please use international standard units like liter, milliliter, grams, °C (degree celsius). Shouldn't we all be a big family? Worldwide like the www? That would be cool. Very cool.

Thank you very much for your patience and best regards - Reinhold

Lucky SHD 100 - Caffenol-C-M

"Hi,

my name's Frank and I started developing film about 1.5 months ago. I have developed various drugstore C41 films with B/W-chemistry to be familiar with the development (it was just cheap) and to test my analogue cameras. Then I developed some APX100 and TMax100 using Rodinal.

Being a lover of drinking coffee I immediately was enthusiastic about developing film with coffee as I heard about it. Searching the web I found Reinhold's blog and was grateful for the recipes in grams and liters. Looking for cheap films to experiment with I got notice of the Lucky SHD 100. The film has no halation protection  and is said to produce what sometimes is called an "aura" effect.

The images shown were taken with an Olympus 35 RC rangefinder at EI 100 and developed in Caffenol-C-M for 15 minutes at 20 °C. The first minute I agitated constantly, thereafter 3 times per minute. Fixing was 4 minutes in Tetenal Superfix (1+3).

Subjectively, I would say that the film can be compared to Caffenol-C-M developed APX100. A strong aura effect is not noticable, but I had exposed the critical subjects sparingly.

I also shot at EI 200 up to EI 800. EI 800 was unusable. EI 400 still seems to be working well. Since I have not documented the settings and I'm not so sure I don't want to make an "official" statement.

Frank"

Thank you very much, Frank. Again the pictures show all the good properties of Caffenol. Excellent contrast handling, awesome shadow details, sharpness and very nice grain. And the good quality of the film is quite a surprise for me.
