Consistent quality every time

I've bought this three times now. It's incredibly consistent, which is crucial when you are developing your own film. Highly recommend for beginners.

Great results, fast shipping

Used this for a batch of ECN-2 film. Results were clean with no color casts. Only giving 4 stars because the bottle cap was a bit tight to open initially.

Good value for the volume

500ml goes a long way for occasional shooters. The free shipping was a nice bonus. My negatives look sharp and the grain is well-controlled.

Excellent for travel kits

Since it's already a working solution, I don't need to carry graduated cylinders or scales when traveling. Just pour and develop. Very convenient.

Perfect for home development

This working solution saved me so much time. No mixing powders or worrying about ratios. The colors on my Portra 400 came out vibrant and accurate.

No more chemistry headaches

Switching from powder kits to this ready-to-use solution was the best decision. Zero mess and the development times are exactly as advertised.
