Here are some images I made in black and white of the white orchid. Again, the orchid is by a window with morning light streaming through augmented by a reflector on the opposite side.
I could have shot these in color and then in post do a b&w conversion but by setting the camera to the B&W mode I was able to see the values of light and shadow immediately and could re position to shape the light. I was also playing with the contrast levels.
The second image down has a very slight addition of sepia, about 10 per cent.
