hears my thought I think in this normal mix the grain is way to largeMartin wrote:I tried that one. At 405nm that mixture didn't produce anything holographic. Speed was low. I believe the material doesn't provide the necessary resolution. Note by the way, that these ferric/silver nitrate mixtures are supposed to produce metal (= "black") silver. So similar to AgX, you'd have to bleach the layer subsequently.dannybee wrote:ooo Iron-silver this might be interesting using the hardning of the Ammonium Ferric Citrate, and the senitvity of Silver
The Process
Sensitiser
note: rinse all utensils in distilled water before use.
Make 3 separate solutions;
6g Ammonium Ferric Citrate in 22ml distilled water
1g Tartaric Acid in 22ml distilled water
2.50g Silver Nitrate in 22ml distilled water
but if we handle it like Hans DYI Process we can get the grain small (just like in silver)
process Idea
1 Silver Nitrate in the gel coated onto glass
2 30 sec in bath of Ammonium Ferric Citrate
3 Rince in di water then let dry
my thougth here is the Ferric will harden the gel with the speed of silver (Ferric/Sliver) also dyes can be added as needed
with a bleach and fixer it can be processed like a DCG .....its a idea
