Black and white in Brixton

I found myself in Brixton Market, which is a wonderful place to take photographs. The stallholders must be quite used to it by now. The intent here was to take a picture of a rather dramatic fishmonger and meat shop. One of the assistants insisted in being in the picture. When I got to look at the picture afterwards, the assistant suddenly became the main feature. I decided to convert to monochrome because the original had some strange colours, which were possibly down to the lighting, and I could not correct for, and the mix of colours did not leave me with a feeling of satisfaction.. As I had shot in RAW, the conversion was problem free.The original jpeg is below. At least the fish look more like fish.

This was shot with a Canon G12 on the auto setting which produced F4 at ISO 80 at 1/80th. I am guessing that the exposure was calculated for the white coat and the fish at the front. A good case for manual control and bracketing, but the monochrome outcome was good for me. I am increasingly using monochrome conversions from RAW.
