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.

They made a nice film about their work process and posted it on vimeo.com. See:

Their website about their Execution Project with more info and nice examples:

They make also tintypes of insects, etc.
And the link to their original post on LikedIn:
