Lighting is just about the most talked about and debated subject in the entire aquarium hobby. Right off this means your going to get a lot of opinions that are very different.
To try to answer your specific question, because each tank is different, and the lighting preferences of the owners are different, there are no "correct" or best settings. If there were such a thing we wouldn't need to have fixtures that could be set up to vary the color and amount of light produced.
Just to give you an example. In looking at the pic you posted, I find the lighting to look far too blue for my tastes. Note - I'm talking about the picture as posted. I realize that some cameras will add a lot more blue to the picture.
I can tell you that I have 4 AI Hydra 52 fixtures over my 125 gal reef, and I run them with a 8 hour photo period, with a 1 hour ramp up before and a 1 hour ramp down after. All colors are run at 80% max. At night the blue is run at 5% for moonlights.
That's as good a place to start as anywhere. Then over time adjust the light setting up or down so it acts the way you want it. For example you might want to use less red to try and control algae.
There are no hard fast rules here. You can't go too far wrong. It's easy enough to change the lighting setting to something else if you feel you like it better.
