Consistent results every time

I've used this kit for over ten rolls now and the consistency is impressive. No streaks or uneven development. Highly recommend for student photographers.

Excellent starter kit from Tuohai

Everything you need in one box. The wetting agent prevented water spots effectively. This is now my go-to recommendation for friends getting into analog photography.

Good but short shelf life once mixed

The chemicals work great fresh, but I noticed the developer lost potency faster than expected after mixing. Make sure to use it within a few weeks.

Great value, standard quality

You can't beat the price for what you get. It's not a premium specialist chemical, but for general street photography and portraits, it delivers clean negatives.

Perfect for beginners on a budget

I just started developing my own film and this kit made it so easy. The instructions were clear, and the results on my Ilford HP5 were fantastic. Great value for the price.

Solid performance, slight odor

The developer works very well and produces nice contrast. The only downside is the fixer has a fairly strong smell, so make sure you have good ventilation in your darkroom.

5 FAQ

Q: How many liters of working solution does the developer powder make?

A: The developer concentrate included in this kit makes approximately 1 liter of stock solution, which can be diluted further depending on your specific workflow requirements.

Q: Can I reuse the fixer solution for multiple batches?

A: Yes, the fixer can be reused. We recommend tracking the number of rolls processed; typically, 1 liter of working fixer can handle up to 20-24 rolls of 35mm film before exhaustion.

Q: What is the recommended development time for ISO 400 film?

A: Development times vary by film stock. Please refer to the detailed chart included in the package insert or visit our website for specific times for Kodak Tri-X, Ilford HP5, and others.

Q: Is a separate stop bath required or is it included?

A: A stop bath component is included in the box. You do not need to purchase vinegar or a separate acid stop unless you prefer a specific brand.

Q: Can this kit be used for developing color film?

A: No, this kit is specifically formulated for black and white negative film only. Using it for color film will not yield correct results.
