Works well but strong odor
The chemical works great for developing, but be sure to have good ventilation. The smell is quite potent when mixing the stock solution. Results are professional though.

Classic results
If you miss the old Kodak days, this is the closest match I have found currently on the market. Deep shadows and crisp highlights every time.

Reliable and Consistent
I've processed hundreds of 8x10 prints with this batch. The activity remains stable in the working solution for several hours if covered. No fogging issues observed.

Great value for students
Perfect for my university darkroom class. It's much more affordable than buying pre-mixed gallons, and one liter of concentrate goes a very long way when diluted properly.

Excellent D72 Alternative
This developer works exactly as expected for a D72 formula. I get consistent neutral blacks on my fiber-based papers. The concentrate mixes easily and the bottle arrived well-sealed.

Good contrast control
By adjusting the dilution ratio, I can easily shift from normal contrast to slightly softer tones. It handles variable contrast papers very well. Only wish the label had more detailed mixing charts.
Q: Is this solution compatible with resin-coated (RC) paper?
A: Yes, Paisen BW61 is fully compatible with both Fiber-Based (FB) and Resin-Coated (RC) black and white photographic papers. Development times may vary slightly between the two types.
Q: How many 8x10 prints can I make from one liter of concentrate?
A: Yield varies based on dilution and tray size, but generally, 1 liter of concentrate can produce approximately 2 to 3 gallons of working solution, capable of developing roughly 100-150 standard 8x10 prints before exhaustion.
Q: What is the recommended storage temperature for the concentrate?
A: Store the unopened concentrate in a cool, dark place between 50°F and 70°F (10°C - 21°C). Avoid freezing or exposing the bottle to direct sunlight to maintain chemical stability.
Q: Does this contain hydroquinone?
A: Yes, as a standard D72-type formulation, this developer contains hydroquinone and metol. Please handle with care, wear gloves, and ensure adequate ventilation during use.
Q: Can this be used for developing black and white film negatives?
A: No, this formula (D72 equivalent) is specifically designed for photo paper. Using it on film may result in excessive grain and high fog levels. Please use a dedicated film developer like D-76 or HC-110 for negatives.
