I am challenged by the Black and White month. Finding subjects that maybe good in monochrome is not trivial. It's certainly a good exercise for my soul :-)
I love black and white photography but by the end of February, I am ready to take a break. My mentor Richard Sayer posted almost exclusively in black and white. He was a master at it. I try to post pictures this month that would make him proud of me. But It is something you can work on all year long. Try to include a few black and white every month. The more you work at it the better you become at recognizing good subjects
