In the process of trying some papers for the first time, I adapted D-72 with increased Metol, reduced Potassium Bromide, with the addition of Benzotriazole following the most frequent recommendation. Metol 4g Sodium Sulphite (anhydrous) 50g Hydroquinone 12g Sodium Carbonate (anhydrous) 65g Potassium Bromide 0.5g 200ml Benzotriazole 1% solution. water to make 1000ml. Dilutions used 1+1 and 1+3. 3 minutes development time. The results were strong blacks, good tonal distribution and reasonably neutral-to-cold tones on Kentmere Bromide but not definite blue-black tones. Kentona still maintained its warm tone. In the June 2006 issue of 'Black & White Photography' (UK) Mike Crawford gives an example of Kentmere Kentona developed in ILFORD Cooltone developer (now discontinued) displaying a definite cold tone shift from the paper's usual warm tone. I didn't mix Maxim Muir's blue-black developer I as don't have any Sodium Hydroxide in stock. Any ideas on achieving results closer to ILFORD Cooltone developer? Tom.
