The wet collodion process had a major disadvantage. The entire process, from coating to developing, had to be done before the plate dried. This gave the photographer no more than about 10-15 minutes to complete everything. This made it inconvenient for field use, as it required a portable darkroom.
What were the advantages and disadvantages of the wet plate collodion process?
The collodion process had several advantages: Being more sensitive to light than the calotype process, it reduced the exposure times drastically – to as little as two or three seconds. Because a glass base was used, the images were sharper than with a calotype.
What are wet plate negatives?
A wet collodion negative is produced through coating a clean glass plate with collodion. The plate is then made photosensitive through immersion in a bath of silver nitrate. The plate is inserted into the camera and an exposure made, typically lasting only a few seconds.
What was the advantage of the wet plate process?
The collodion process had several advantages. * being more sensitive to light than the calotype process, it reduced the exposure times drastically – to as little as two or three seconds. This opened up a new dimension for photographers, who up till then had generally to portray very still scenes or people.
What did the wet collodion process do?
The wet collodion process used a prepared piece of glass which, in the darkroom, would be coated with collodion and then made light-sensitive with further chemicals. Before the plate could dry, it would be placed in the camera and exposed.
What are the three wet plate photography processes?

How does the collodion process work?
The wet-plate collodion process involves a huge number of manual steps: cutting the glass or metal plate; wiping egg-white along its edges; coating it evenly with a syrupy substance called collodion; making it light-sensitive by dunking it in silver nitrate for a few minutes; loading the wet plate carefully into a “ … Check the answer of

What are the necessary steps in protecting glass plate negatives?
After individually enclosing each negative in an envelope, glass plate negatives should be stored vertically along their longest edge and placed into appropriately sized document boxes. Negatives should be stored with other plates of the same size in order to prevent edge pressure on any odd sized negatives.
