Love the lighting in this photograph.
It gives a good feeling of depth to it.

Thats kewl.

Funny effect of the settings used.

I think you could do without the "ghosts"...

Try longer exposure and maybe something like:

exposure time: 20-30 sec
aparture 9-11
ISO 100

A slightly different angle and putting St Paul's a little off center could be an option (next time).

Your comments are appreciated. Thank you.

Moser: I did try your suggested settings and out of 5 captures, this was the one I preferred. A new post without 'ghosts' in the future, perhaps.

Thanks again guys.

I like the ghosts!!! Nice effect, I agree with Patrick comment regarding a slightly different composition.

Very nice effect and beautiful lighting!.....maybe a little more off center would look better.

Intriguing. I like the ghost figures and the overall tone of the image. I'd love to see this without the streaks, if you wouldn't mind.

Very nice. I like the symmetry presented with the centered composition. Would crop a bit off the left side to make it even more symmetric though.

Cool colours and nice ghost effect

Nice light effect!
agree Carlos comment

I like it a lot! It only bothers me a little the big black zone to the upper left. It would be nice with some little light to balance it (well, I´m not into photography except for the joy of watching it, so don´t mind me)

nice work, its cool
