No one can do a good job without proper tools, and the chemicals can be defined, the tools of the photographer. This is the weak point of many operators. They work with economic and inferior chemicals, and many do not know the true composition; not to mention unwanted interferences that can be created between them.
“Chemicals are the tools of art photographers. Through a deep knowledge of photo chemistry the artist can reach and master the art photography level.”
