Originally posted by incidentflux OK I finally found where to get a download of full size.and have had a bit of time to look at the images and EXIF more closely.
As several of the other posters have said looks to me like the color balance is fine. For example if you look at the first two images there are some of the lights that are a perfect white light while some of the lights are blue and in second shot some of the lights that were blue are red or pink . . .looks like these are coloured lights that are changing colour. Also possible that some of these lights are of a nature (mercury vapour) that give off a cloured hue. Also look at the last picture of the cabana and again you have some nice white lights and some blue. This must be as the scene was. If the colour balance were off it wouldn't be selective like that.
In looking at the EXIF I noticed you are on Firmware Ver 1.0. I would suggest upgrading to 1.04 . . .not because of white balance but there were other issues that have been corrected/improved. Also, what colour space are you using? Also in the first 2 pictures white balance is set to AUTO or ) in the exif but in the next 2 it is set to 1 and I am not sure what that is as I never use anything but auto.
I finally saw how to get a full sized version and downloaded into PS picture 1. Colour balance is fine according to curves in PS and according to what I see in the photo.
