Sorry for leaving out the thought process

The WP notion came as an extension of home production, being the home made neg' process currently regaining popularity, Sally Mann and a few others - To me it seems too tedious and where do I get gun-cotton to dissolve in ether?

Well, what I practice uses no guncotton nor does it use wet plates. These are dry and keep for months without change. They have an ISO rating of about 40 and can be made ortho sensitive. I've gotten panchromatic emulsions but they are too hard to work with in the dark unless you have IR goggles.

But, regarding guncotton (or cellulose nitrate), it comes ready to use from a number of alternative photo supply distributors.
