??, here's what I have done. 6x6 cm Negatives were exposed in a Durst M707 enlarger using a 500W floodlight and then developed for a fixed amount of time( approx 3 min) in Ilford ID78 diluted 1+3.
All images were scanned without tweaks and only auto levels were applied.
It seems that the fog levels rise, possibly because of the ammonia, and the contrast is lower. I'll try a 1-5% KBr bath after before development to see it it will cut base fog levels a bit while keeping the speed.
Ammonia preliminary bath: 1 part 10% NH3 solution + 20 parts water
Ammonia + Erythrosine bath: 1part 10% NH3 + 10 parts 0.003% (300mg per 10 l) eythrosine solution
Erythrosine + Tartrasine solution: 1 part erythrosine + 50 parts tartrasine + 6000 parts H2O + 3000 parts Ethyl Alchohol
All solutions were @ 15C due to extreme cold weather and inability to adequately heat the DR
here's a color snapshot of the objects
a crop from the above images in the same succession( left to right, top to bottom)
PS: the setup may seem ridiculous but that's all I could do :P
