Hi Harold,
welcome to the site.
I see from your avatar that you are maybe UW photographer.
It will be excellent for this forum!!!!
I done UW photos long time ago but now no time for it.
Unfortunately, I am not a UW photographer. This avatar was taken while I was diving in Maui… But I am a very low level diver (12 dives in total) and I have too much difficulties with the boyancy to take UW photos :(
