ABSTRACT
Each process has its own tonal range, but they are sometimes hard to tell apart. I have always gotten a nice rich tone with VDB sensitizer. However, with kallitypes you can change the tones from reddishbrown to darker browns just by changing your developer. Argyrotype colors can shift easily by adjusting the humidity in the darkroom. All three can be toned to further shift the colors and they can all be used in combination with other processes. As with the other processes discussed in this book, experimentation is key – but make sure you keep good notes as you go along so you can duplicate your successes.
