Just tested embedding images and it worked! Thanks.
As for the orange gel, I have Polylab's Coral View Lens and Orphek Reef Aquarium Lens, still couldn't make out nice pictures! Will try again.
Looks like you have necessary tools already! Which camera do you use to take pictures? The shots I took were at night so white LEDs were pretty much off, leaving only blue/royal blue and some violet.
My filter is the orange one (14000K from the Orphek set looks closest) but you need to make sure your camera's color temperature is also set to 14000K - most cellphone cameras may not have ability to adjust color temperature to this. Also, since the filter reduces blue light where your light fixture is providing mostly blue, there's a lot less light to capture now meaning you need large aperture, high ISO and probably longer shutter time to compensate for the lack of light...
To be honest, the user photos on Polyp Lab's website aren't too impressive. It's definitely better than without the filter, but definitely not making the best use of the filter.
Thanks for sharing all the details. Your tank looks fantastic as usual, looking forward to seeing the tank fill up as before!
