I did John Coffer's workshop this past week, and it was great! Wet plate collodion is a tricky process, to say the least, but we poured a lot! If you have been thinking about learning this, he is a great instructor!!
Thank you all, very much!! I fear I may be lost in this, too!! I need to pull together a few things to do it properly, but Jose, you'd be surprised how easily this can be done. (You really only need a brownie camera!!!)
