Caffenol

- all mixed up




1. I think i got all ingredients mixed up during the last processing as written here.  The photos that showed the weight of each ingredients on the scale could testify to that. 

2. The order of 27g, 8g and 20g was supposed to be Wash Soda, Vitamin C and Coffee.

3. Instead, it was Coffee, Wash Soda and Vitamin C.

4. I have forgotten the order of which the ingredients were mixed but from my note shown in one of the image in that post that it started with coffee then soda followed by vitamin C.

5. Apparently the development was as good.

6. So, i was wondering whether the order is that important and the weight was also could be of different portion.

7. I am not sure if the negatives came out better quality or more contrast what not if i mixed the formula as per recommendation in the original block posting.

8. For comparison as far as cost for the two, the original formula came to rm2.93/500ml as compare to 'mix-up' formula to rm3.77/500ml.

* soda from hardware shop = rm55/1500g > 0.055sen/g
  vitamin C from a dealer in Poland = rm93/1000g > 0.093sen/g
  coffee from local supermarket = 11.90/200g > 0.059/g

9. It seemed that the 'mix-up' formula was very much more acidic than the original formula when the vitamin C was 20g compare to the
original recipe of only 8g.

10. In order not to get mixed-up again, the container of each material was clearly marked with the name, weight and the order it should be mixed.


11. Here you could check are the images that had been developed as suggested.
