Another method that has not been addressed is a method that Blansky uses all of the time. That is retouching the negative. In talking with him, I learned that he does this a lot in his portraiture.
I recently bought an Adams retouching machine and have used it in retouching some of my negatives. The technique takes some practice but works very well. I have retouched some fairly sizeable areas. By applying the retouching dyes the negative density is increased...this has the effect of allowing one to burn down the other areas, if desired. It could be used as only a dodging method too.
The dyes that I use are sold by Veronica Cass. This is a reversible procedure. If too heavy a application of dye results, one can rewash the negative and start over.
