1st off getting it right when shooting is important - correct exposure, and shooting frames with different amounts of light and/or with different colours.
EDIT, add this important bit in: I shoot RAW, and in Adobe camera RAW I take the contrast down to 0, minor adjust any exposure necessary, and try to have 'recovery' and 'blacks' as low as possible while keeping a good exposure. 'Blacks' slider in particular can eat up detail if you have heavy shade.
Then I use Silver Efex Pro in photoshop (2nd best to that is channel conversion). Use variations of colour filters (or no filter) to get the right effect. For example, shot #2 is a blue wall, using a yellow/red filter makes it black while making skin a more pleasant light tone.
I stay away from contrast and brightness sliders (very destructive), you can do that all more effectively with curves adjustments, levels can also be useful for touch ups or to get strong contrast (still better than contrast slider). Silver Efex Pro does add a few useful sliders in 'structure' and 'local contrast' which bring out detail well.
