Great value for money

Solid developer that produces fine grain. It smells a bit stronger than some competitors, so ensure your ventilation is good, but the image quality makes up for it.

Good but instructions could be clearer

The product works well once you figure out the right dilution for your specific film stock. As a beginner, I had to look up extra guides online to get started.

My new go-to developer

Switched from D-76 to this and noticed immediately cleaner highlights. The 500ml bottle lasts a long time since I usually dilute it 1+15 for standard box speed.

Perfect for street photography

The acutance this developer provides is fantastic for street shots where edge definition matters. Easy to mix and stable working solution.

Excellent contrast control

I've been using Paesen BW-60 for my Ilford HP5 Plus rolls, and the results are consistently sharp with beautiful tonal separation. The dilution flexibility allows me to tweak development times easily.

Consistent results every time

Very reliable chemical. I process about 4 rolls a week and haven't seen any variation in quality. Just wish the shipping wasn't excluded from the base price.

5 FAQ

Q: Does the 500ml bottle come with a measuring cup?

A: No, the bottle contains only the concentrated developer solution. We recommend using your own graduated cylinders or mixing beakers for accurate dilution.

Q: What is the recommended storage temperature for the concentrate?

A: Store the unopened or opened concentrate in a cool, dark place between 15°C and 25°C (59°F - 77°F). Avoid freezing or direct sunlight to maintain potency.

Q: Is this compatible with Kodak Tri-X 400?

A: Yes, Paesen BW-60 is fully compatible with Kodak Tri-X 400. A common starting point is a 1+9 dilution for approximately 8 minutes at 20°C, but we suggest checking our online time chart for precise adjustments.

Q: Is this suitable for developing expired film?

A: Absolutely. Many users find that BW-60 helps recover detail in expired films. You may need to increase development time slightly, usually by 10-15% per decade of expiration.

Q: Can this developer be reused, and if so, how many times?

A: Yes, Paesen BW-60 can be reused. Depending on your dilution ratio and film type, you can typically process 4 to 6 rolls per liter of working solution before exhaustion.
