I hope you don't mind the question, I am looking at lighting options for a new build and I came across this picture. To me this represents the 'perfect' look/colour temp. that I had in mind when I picture a reef tank and so different from the 'windex' look that so many seem to like. Since I enjoy photography a bit myself and noticed you use a decent camera I was curious about the white balance of the shot and if you had to correct that in post-processing. I don't mean to imply anything negative by that, I understand the reality of post-processing and its necessity in many cases, I am just trying to inform myself properly and the area of lighting seems to be filled with a lot of contradictory information and quite expensive choices.
