Ever since Hipstamatic released their TinType SnapPak I've been trying to recreate the look in Photoshop.  I think I've almost got it figured out.

Here's a bit of history for you about Daguerreotypes.....

The world’s first photographic process was announced in Paris in 1839 by Louis Daguerre. It used a silver-plated copper sheet that was sensitized with iodine, exposed, and then developed in mercury vapor. Early images were of architectural subjects or landscapes, but soon the process was also used for portraiture, and it became particularly popular in France and America. Daguerreotypes were one-offs, and the process was obsolete within a decade, as soon as new techniques allowed multiple photographs to be printed from negatives.
