I recently received 4X5 Black Glass from PICTORIOGRAPHICA for ambrotypes

Nicely finished edges, black glass which is dark enough to barely view a bright light through it, I wonder if it may be good for ND filter?

and the 4X5 plates fit my 5X7 Chroma Wet plate holder with a spacer

as usual nothing to show here yet

I have had some issues of my own making
