Without having to adjust the LED light to mostly white, is it possible to take nicely exposed tank shot with LED around the 18k range using iPhone? The blue always seems to get unnaturally saturated even with an orange gel (slide) overlaying the lens... any tip?
Good photo with iPhone 6 + LED?

Nope. Can't be done.
Because the light of 18k reef light esp led IS unnaturally saturated.
I'd would also wager my color meter it's not 18k. The color of a valley at ten am not in direct sun is 20k.
The other difficulty is the camera is RGB. And there is little to no r and g in the led's

You need to get a piece of yellow or light orange plastic to put over the lens. This will correct the overly blue tint to your images.

let me try to find it but you really have to play around with the filter gels i have AI vegas and i tried the same filter on my friends tank he's running kessils and the yellow filter didn't work on those lights and i tried a green filter and got the same effect. So you have too play around with them

These will last you forever. I use this for my cellphone only to take videos, converts a 16k to 12k perfectly. Its like a 2 foot by 2 foot square, so i cut new pieces everytime. If you use the same filter over n over it gets scratched and fingerprints

I've turned my blue channel to 80%-100% and then change phone camera to darkest setting. Then take a pair of sunglasses and place it over the lens. It can be a little difficult but it will act as a filter until you can get a real filter.

For the Op. A quick think on color temprature.
So to get a photo with no overly saturated colors like in Reeferfoxxs pics is pretty much impossible. But still a totally cool pic.
Filters directly remove a specific frequency or range of frequency . The Lee filters Sabellafella is using actually has that data marked on it in the dozen or so Swatches I have from them Roscoe and tiffen.
All that being said, when your playing with the filters choose one that is the exact opposite of the light you have. A 420-440nm (royal blue)led is going to need an orange red or when combined it's Amber. and so on.
If your going for a more realistic pic Like Sabellafella's youll actually need to add spectrum or have it available in the light, not so much as only remove(filter) it. (so you need to change the led ratio to less blue)
@Sabellafella fyi on a dslr or film camera a glass filter that color(CTO) is an "85" 85a or 85b. Usually pretty cheap as it was really for film and shooting in extreme blue (ocean and indirect sun lit valley 10 to 30k).
But very handy for a lower end dslr that wont take true color temps above 15k, or a high end diggital Cinema camera in a valley or ocean.
Glass yellow filters are also pretty common and cheap too as they are used in black and white photograpy. and yes you can stack them to create amber. red too, but red is usually too a dense filter.
This is not 20k, closer to 45+ and not really a temperature so much as as a narrow frequency 420 450nm. with NO other colors of the spectrum available to the Green and Red sensor (nice shot btw) note the overly saturated colors you mentioned. This is due to the RGB sensor trying to simulate R&G when there is little to none.I've turned my blue channel to 80%-100% and then change phone camera to darkest setting. Then take a pair of sunglasses and place it over the lens. It can be a little difficult but it will act as a filter until you can get a real filter.
this as stated is 16k (btw WOW bro honing your skills I see)

this is quite likely closer to 20k with h a high spike in 440 range(as yellow is opposite in the spectrum not orange)Orange filter
Yellow filter

I understand. I kind of knew it wasn't anywhere close to 18k or 20k. I didn't have any other images showing an example of how a filter would work. Although, I was only suggesting a pair of sunglasses would help get the foot in the door. Or at least strike some kind inspiration.
And you nailed it!I understand. I kind of knew it wasn't anywhere close to 18k or 20k. I didn't have any other images showing an example of how a filter would work. Although, I was only suggesting a pair of sunglasses would help get the foot in the door. Or at least strike some kind inspiration.
This is actually why the sunglasses work.And the yellow binder clip. And also why it doesnt work sometimes too
I was just hoping to explain a bit of the science as well to hopefully strike some sort of inspiration too.
