The silver nitrate bath was also a source of problems.It gradually became saturated with alcohol, ether, iodide and bromide salts, dust, and various organic matter.The collodion process had other advantages, especially in comparison with the daguerreotype. The polishing equipment and fuming equipment needed for the daguerreotype could be dispensed with entirely.The support for the images was glass, which was far less expensive than silver-plated copper, and was more durable than paper negatives.
During the subsequent decades, many photographers and experimenters refined or varied the process.
Other artists to note are Luther Gurlach, James Walker, Stephen Berkman, Sam Davis, Quinn Jacobson, Shane Balkowitsch Ken Merfeld and Conrad Young.
There are many more as well that have contributed to bringing this process forward to a modern age.
Collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field.
Collodion is normally used in its wet form, but can also be used in humid ("preserved") or dry form, at the cost of greatly increased exposure time.
The dry gelatin emulsion was not only more convenient, but it could also be made much more sensitive, greatly reducing exposure times.
