I thought some of these images would look good in B&W so I set at it with my favourite converter, namely Nik SFX II which is just about the best converter on the market right now. Firstly I'll show the image in colour and then as a finished monochrome image.

I'll let you decide if it was worth it or not. So here goes with the first image and the reason I thought it would convert well was brcause of the contrast between the sky and the row of houses down the bottom. I like this image in colour too.
