Let's make this clear, I'm not really a Jazz person at all. But I don't mind listening to it all. As long as I don't have to listen to it day all day long! Out of curiosity I looked it up on Google and found out that, for some reason most of the Jazz shots are in black and white.
My guesses are since the band is playing in an environment with the lights dim, it will be better turn the shots into mono and get more details out of it. On the other hand Black and White also tend to give people a strong feeling and connection towards the image.
So without further delay here is two image from the Jazz Night. Let me know what you think, and would you turn your images to black and white? And what's your reason for it.
