For me the key point was when I read Mr Jolly's paper about this process.. Following his chemical mix to the letter was very important. I use his two developer method for prints and one developer method for film.
Did I mention Metol only , not Hydroquinonne..... probably the most important factor.
Many papers work well, I just gravitated to Ilford Warmtone.
If you are in Toronto in May I will be showing my new work at the Contact Festival, and if you are in Alberta in Feb 2013 , I will be showing this work there as well during their photo festival.
I am concentrating my efforts now on film solarizations and printing them big on Art 300 paper. I have been using an old 8x10 Studio camera as well as 4x5 and really like the simplicity of the quick flash smack dab in the middle of development.
