Which is better? (Trevi Fountain)

[poker]

This is in Rome at the Trevi Fountain. We went at night since our guide book said it was better to go at night.

The smaller picture is the original shot with these specs:
1/4 seconds
F3.5
ISO 200
18mm
I was able to use a tripod.

I took a handful of shot but they came out yellow. I guess that is to be expected with this type of exposure? When you are there, you can actually see the waters blue reflection but I couldn't capture it at all.

The larger shot is a modification in PS using the color balance.

Was my Photoshop work justifiable?
