Maastunnel air vent Rotterdam

Hi,

I want to go back to taking more black & whites. This is a picture I

believe turned out nice. I did not change it using Photoshop or any

other tool so it comes as is.

Since I took it on XP2 which is chromogenic, I wasn't able to use

coloured filter to enhance contrast.

I'd like to receive comment, any will do.

Many thanks,

Arthur
