Tunnel vision

A beauty.

well Timed and interesting composition.

Can I ask, Colin, how you metered this shot. It doesn't look to have been easy to cover the range of light. Thanks

I metered off of the ambient daylight. That's all that matters - I don't care about the inside of the tube because it's in the dark, it's supposed to be darker. Lucky in that it was overcast, so bright and soft lighting overall.

Thanks Colin. Yes it is dark inside the tube but nothing like as dark as I had expected it to be and yet the outside scene isn't blown either. It was this "squaring the circle" that you achieved that I wondered about. I once took a wedding shot of the bride's father giving his speech and he was against a window with the summer's light and while he came out fine, the outside scene which was the equivalent of outside of your tube was blown but yours is not.

Maybe if I had risked a shorter exposure of the inside of the room where the bride's father was, I might have been able to "square my circle" better than I did. He'd have been darker but still OK and the outside would not have been blown - maybe

.

Well, what might have helped is that the tube was fairly short - maybe 10 feet at most. So it likely let in a lot of daylight as well.

This has worked very well. I like this type of shot but when I do it the bright scene is well exposed and the dark bit is well under which requires a complicated dodge or burn. I actually did something similar very recently but I haven't printed it yet. Perhaps there is not too much dynamic range in this shot and the inside of the pipe was relatively bright?
