Recently I've gotten into street photography. Whenever I flip through portfolios or google street photography for inspiration, I see that many pictures of people are in black and white, but there are some that are in color. When should you use black and white? I am editing some photos and I just cannot decide which is better. I'm not sure if I should post an example picture, so if you need a reference so you can help me with a complete answer please let me know and I'll leave one in the comments!
