Yellow Camera Lens and LED

[Tradewinds]

I was talking with a friend in the local reef club and he mentioned a RC thread that suggested a yellow camera lens would improve the photo quality when using LEDs over the tank. The yellow filter will supposedly take reduce the blue tint.

I have not been able to find the thread, but wondered if anyone has experimented with a yellow lens and what his or her results where.

I have no idea if that's true or not, but honestly, it's incredibly easy to adjust the white balance in post processing (and you don't need Photoshop to do it). I personally wouldn't spend money on a lens filter like that.

It's not about white balance. The yellow lens trick is about capturing flouresce in corals using exciters such as blue light and using yellow filters to remove the blue but capture the neon green or red orange fluoresce of the coral. It's actually pretty neat. Here's sime pics of my attempts.

What is an exciter?

An exciter is a term used for the light source wether it's a strobe a flash or a flashlight. As long as it excites the flouresce in the coral when fired at it. It's usually a bright blue spectrum like the Royal blue leds. In the case of a camera you simply put a film or gel over the flash to change its color output to blue

No photoshop. A yellow lens and a blue film on the flash. I'll take a picture of the set up in a second
