Most people hit a brick wall when it comes to getting their hands on the chemistry (which is many cases is illigal to buy), so here’s a few pointers to get people started. Information First of all. Buy a book. Sure, there’s lots of info online, but a lot of it is wrong, and it takes forever to figure out what’s solid. I learned on a workshop from Quinn Jacobson, who’s book is still my go-to place for recipes and troubleshooting. Also; if you want to skip some of the most frustrating experiments take a workshop. On Facebook there’s two main groups: ‘Collodion Bastards’ and ‘Wet Plate Collodion’. Chemistry WARNING: Some of this stuff is truly dangerous (especially ether, cadmium bromid and – if you really want to mess with this – potassium cyanide. Some of this stuff is hard/impossible to get in Denmark and probably most of Scandinavia.

Per quanto riguarda la chimica e tutti i prodotti, il collodio deve essere di tipo USP tra il 4-6%, altri tipi non sono adatti. Per l’acqua distillata e buono procurarsene di buona qualità pena insuccessi, le delusioni sono dietro l’angolo. L’alcool dovrà essere necessariamente puro, non denaturato, minimo 95/96°, rigorosamente trasparente. Il primo passo è quello di aggiungere l’alcool al collodio, è buona norma non fare il contrario.

Wetplate Collodion. Getting Started InWetplate Collodion Photography By Joseph Smigiel Historically, the popularity of the wetplate process was short-lived.

Wetplate Collodion

From its invention by Frederick Scott Archer in 1851 the process flourished until the introduction of dry plates in the early 1880s. The process was safer and more convenient than its predecessor the Daguerreotype, and much sharper than its contemporary the Calotype, but wetplate collodion still required the proximity of a darkroom and the preparation, exposure, and processing of the plate all within a matter of minutes. The convenience of dry plates which could be prepared in advance and processed long after exposure quickly led to the abandonment of the wetplate process by most studio and location photographers.

Today, a wetplate revival is occurring, sparked largely through interest in Living History and the imaging revolution centered around digital technology. Alexey Alexeev Photography (Ambrotypes, Tintypes, Wet-Plate Collodion) - Wet-Plate Collodion Process. Ambrotypes. Wet-Plate Collodion Process.

Ambrotype Introduction Wet-Plate process was invented by, an English sculptor and photographer, Frederic Scott Archer in 1851. He experimented with collodion in the hope of producing a photographic negative on ordinary glass plates. He also found that underexposed very thin negative looks like good positive being placed on a black background. Part 1.

Writer and photography / Jalo Porkkala Got an old Polaroid camera sitting around somewhere?

Wet plate collodion with a Polaroid camera « Cameras, Film & Technique

Since the camera film making business is on decline (Polaroid is no more, Fuji film is still around) the camera needs to find other uses. For example; take the film holder and convert it to an excellent wet plate holder. Jalo Porkkala shows you how. Most collodion photographers are using dedicated wet plate cameras, because wet plates are not nice to put into any ordinary modern cameras. A Polaroid EE100 and a wet plate holder made of the pack film holder. There are, however, certain types of cameras that you can use as is, without any modifications. These cameras have automatic exposure, with an ‘Electric Eye’ light meter beside the lens, the shutter is powered by batteries. The neat thing is… if you are careful, the silver nitrate will not ruin your camera, as the metal/plastic plate holder will keep the drops inside.

The holder. Load the holder. The electric eye.
