What materials are used instead of metal plate and paper for wet plate testing?

Wet plate processing is a photographic technique with glass or iron as the negative. This is an ancient photography technique from19th century. The clean glass is coated with solvent with collodion as the main material, then immersed in silver nitrate, taken out and photographed under the condition of keeping wet, then developed and fixed, and the negative film is made into positive or negative film according to preference. Also known as collodion photography.

People want not only clear images and detailed shadow lines like those taken by Daguerre method, but also many photos printed cheaply and quickly like Carlo method. So someone put forward the idea of using transparent film base instead of paper base to make negative film.

Modern significance

Today, with the influence of electronic and digital images, the unique artistry of wet collodion photography is precious and has a lofty and immortal position in photography.

Wet-plate collodion photography can help you get rid of the shackles of film manufacturers' price increase and out of stock and the troubles of flat large films. For example, after Polaroid stopped producing primary imaging consumables, all Polaroid machines in our hands became deaf ears.

For us, except the lens, everything else can be solved by ourselves, the machine can be built by ourselves, and the film box can be DIY by itself. The most fascinating part of this technology is to return to photography itself, so that players can really pay attention to the fun brought by the photography process and stop blindly pursuing equipment? If you are interested, try to buy some materials to practice. It feels good that everything is up to you.
