16"x20" on Black Aluminum.  

Here are a few images of the tent camera I built to do the Mammoth Plates.

The lighting required for this process is massive! Collodion is rated at around .25 to 1 ISO, depending on the sensitivity of the collodion. To get this shot, I used 2 PROFOTO 7a Packs maxed out at full power combined with a Bi-Tube head to get 4800 ws of power. It took all that just to get a good exposure. When the light goes off, you feel the rush of wind hit you...it’s a little crazy. :)

Success at the end of a great shoot!
