Question about the John Coffer book/DVD

[goamules]

But if you want to make glass negatives and just use regular silver gelatin paper, it's easy with wetplate.

The issue is some printing processes need a very dense negative. Wetplate often makes a thin negative. So all the shenanigans of redeveloping or intensifying were invented for those old processes like Albumen (and I believe Platinum, and several other techniques). When I've made a wetplate negative, they print well for me.

The steps for wetplate are fairly easy. You can mix chemistry on the same day that you are going to shoot, for example. When you shoot a plate, you will know in 5 minutes if it's dense enough.

So, where do I buy chemistry/materials for wet plate photography?

Thanks.

Art craft Chemicals, photographer's formulary and maybe even Freestyle will have some things. A certain auction site might have better prices. The book has an extensive list of vendors or at least my copy ?2014? Does. John also sells certain hard to find items at his workshops too according to the advertising. He also answers letters which is pretty cool.

Even if you don't make positives, Coffer's book and DVD are well worth the money.
