Are you sure the unit used then was the inch?


I'm sure the photos will be better if you use cms


;-)


Nice idea about the format, unsure about the pixel count though.

Sujet : [Leica] Daguerreotype Plate Sizes at 72 dpi


 Whole plate        6-1/2" x 8-1/2"     468 x 612 pixels
Half plate         4-1/4" x 5-1/2"     306 x 396
Quarter plate     3-1/4" x 4-1/4"     234 x 306
Sixth plate         2-3/4" x 3-1/4"     198 x 234
Ninth plate        2" x 2-1/2"         144 x 180
Sixteenth plate     1-3/8" x 1-5/8"     99 x 117

I worked the math on these plates sizes into pixels.

I plan on working up some images at these sizes which perhaps will have some
resonance in our photo DNA.

Sometimes I  plan on just entering the inch sizes at whatever resolution I'm
using on the print. As they are a bit small for the screen even.
I really don't know. Maybe I'll find myself using these all the time. Or
hardly ever. But It was fun doing it.
