The blue is created by setting the camera’s color balance to 2300K. Quick post-processing since the RAW is pretty much what I want. By the way, this looks much better in AdobeRGB on my monitor. First time I see the colors change drastically when converting from AdobeRGB to sRGB profile for Web publishing. But no choice 🙁
Forgot to say, please take your time to view this photo in large (1600×600). Recommended :)!
