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.
Sodium Sulphite (anhydrous) 50g
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?
