Re: Wedding dress loooks blue.

Read this:

It is as valid now as when it was written. Wedding dresses are often synthetic satin or similar material, and they have optical brighteners in them which can fluoresce blue with UV light. Flash units can have pretty high UV outputs. If everything else looks right and the dress is blue, this is most likely the culprit.

As an aside, snow in shade on a sunny day should also look quite blue, though not for the same reason....
