    Developer - highly recommended

    Consistent and reliable. Perfect for 11x14 Ambrotypes on glass. I’ve been using it for over 4 months

    Works great for wet plate

    This is the first developer I bought back when I first started wet plate. I mix it 1 part developer and 2 parts water. I'm curious to try the other developers as well but this one for sure works great for me.

    Always a pleasure to use this developer concentrate, modified a bit to my liking and it works wonders!

    I mixed a 1:1 batch for developing tintypes and found that it worked too quickly for my comfort, so I now use 1:2 mix. It flows well and does a nice job of developing.
