Good choice for B/W. It helps diffuse what probably was some harsh lighting conditions and removes distracting colors - allowing the viewer to focus more on the action.
Is there a 'Beautiful Balloon' on the other end of that string? Very sharp and crisp...if it were me, I'd have tried to not crop the wheel out if possible.
hey feels like I have seen this some where before, hmmmmm. New lens seems to be working great, nice and sharp. I think it might have been nice to have the entire board in the photo.
