I have tried to develop a Rollei Tonal 100 4 x 5 with D-23 1+3 + 5cc potassium iodide 0.001% for 32 min. with an unbroken agitation for the first minute and 2 reversal every 3 min.
The result is very good for me: medium contrast, very good definition, high power of compensation and wide tonal scale.
These considerations born only to see my sheets becouse I have no densitomer and I cannot make a prints becouse my darkroom is condemn for the great earthquake of 6 April 2009.
Thank for your suggestions.
