Iron Copper Developer Concentrate

In my years of doing wet plate, this developer has never steered me wrong. My highest recommendation.

Great concentrate, beautiful highlights.

Previously, I had been using iron sulphate developer, both commercial and then homemade, with UVP-Z collodion. Just about through my first liter of this concentrate and can honestly say that I love it. Doesn’t seem to oxidize as quickly (I.e. lasts longer) after mixed and dev time is more predictable for a longer time. Seems to make cleaner, brighter plates, but have not yet made a definitive comparison. I bought my first liter on the recommendation of a friend and very pleasantly surprised at how well it works!

I've been using only this for years, it works the same every time I use it. I'm grateful to have access to such a consistent product.

This developer gives me the best density, thus whiter whites. Must have for glass negatives. It’s been a consistent developing time every time.
