I saw a post in a Linkedin group about "traveling with a 100 year old Mammoth view camera creating 20x24 inch black glass ambrotypes". I was impressed and wanted to share it with you folks.

Their website about their Execution Project with more info and nice examples:
They make also tintypes of insects, etc.
