un moment dans le temps!
Ferrotype? Huh? What's that? It's also known as a melainotype. Most commonly called a tintype. You can think of it as the original Polaroid camera. It was quick, cheap, and produced a positive directly without a negative, and as a result, was very popular the last half of the 19th century.
Ferro refers to iron. There is no tin in a tin type. During the Civil War steel was a scarce, expensive commodity. Railroads ran on wrought iron rails, not steel. And for making unbreakable photographs wrought iron was rolled into very thin sheets and jappaned. Onto that was flowed collodion syrup (first cousin of gun-cotton) with salts dissolved in, sensitized, exposed and quickly developed to give a positive.
8X10 AND TINTYPE PORTRAIT DAY AT PENUMBRA
Sat, December 7th 2013
Impossible is teaming up with with The Penumbra Foundation to offer 8x10 and tintype portraits! We will be shooting in their North Light Studio using antique brass lenses that produce effects as interesting as they are beautiful. We tested many different lenses and hand-picked an Oscar Zwierzina Plasticca to use for this special event. It's unique softness is a perfect fit for portraits on Impossible film. We are very excited for this match made in analog heaven and this is an event that no photography enthusiast should miss.
