Fluorescent diving has become more and more popular over the years.
But in order to sort out the right colours when filing, you need a yellow filter. The yellow filter needs to be placed on the M67 thread on the underwater housing.
It is also possible to get a yellow filter for your mask, so you can actually see what you are doing. Don't forget a prober light for your camera.
And if you use flash - there are BLUE-filters for them too... look in the accessory list.
