After a lot of playing with different cameras (Nikon P900, Olympus TG1, Samsung S20 cell phone and a Go Pro) and playing with some different yellow filter material, I just can't seem to get the look I want.
So, yesterday my wife and I were playing around with features on our cameras and I came across a White Balance feature I was unaware of on my P900. It has several white balance levels you can choose from (like most better cameras). And even the ability to pick your own white balance. But there is this Auto Preset Manual White Balance. So I did a test.
This is what my tank looks like to the camera with all the 'normal' settings and no filters and the tank set with all blue leds.
And then I did the Auto Preset White Balance setting while the camera was looking mostly at the sand. Then I pulled back and took this photo using all the same original settings except for the new white balance and still NO YELLOW filter and the tank still lit with all blue leds.
I think if I do some adjustments to the exposure and the amount of blue led light I can get it even better.
And the reason for wanting to take a good photo is because I'm planning on doing another change to the tank(s).
The stand has the 90g DT at the left end and a 16g frag/holding tank at the other end. I just refurbished the 40g tank I built about 4 years ago. I plan to use that 40g to replace the 16g tank. The new 40g will be both a frag & holding tank, but it will also be a 'local' tank. So the RFAs, gorgonians and a few other local corals will come out of the current 90g DT. The space freed up in the 90g DT will get used by doing some (nothing crazy) changes and additions to the rockscape and doing more sps and lps corals.
The new 40g set up will just use a HOB filter system and a small in-tank skimmer. The local stuff that will go in there is far more accustom to water that isn't high end reef quality.
