4x5: KW Negopock + Harman Direct Positive Paper + Caffenol

Finally yesterday I have pleasure to test my modify KW Negopock camera. Modification allow me to use standard 4x5 film holder. As You may see on picture picture area in Kw camera is slightly smaller that 4x5.

Picture was taken on Harman direct positive FB paper . After experimenting with Adox Adolux R09 1:100 as developer with not much success I decided to use caffenol as developer.

Paper was measure on iso 3. Shoot in available light ( north side window ), F 5.6 ,8 sec exposure time. 

Its hard to buy here soda carbonate/washing soda main ingredient of this developer so i decided make it myself. I bought sodium bicarbonate/baking powder and heat in oven for 1 hour. I didn't notice much change just taste change to more sour :).

Caffenol recipe used for this picture:

400 ml water
3 table spoons of coffee
2 table spoons of baked sodium bicarbonate
lime juice (1)/ while i didn't have vitamin C

Developing took about 5 minutes.

I am very pleased with results. Picture isn't to contrasty I have nice mid-tones as well. I cannot wait to make more experiments.
