nice video. for wide angle shots I have 180 mm dome port how am i going to find a yellow filter on this size to put in fort of the port or any suggestions. thank you
Why not have a camera that can detect the UV light directly, that way you can see farther underwater? Then by using a color filter you could increase the contrast of the resulting image to match our eyes. Hmm a camera that also uses sonar and polarized light would also be awesome...
You missed the point. You don't see UV light. The marine creatures when illuminated with a UV light fluoress and produce a different wavelength (color) that is caught by the eye/camera. They do not produce UV light.
Great Video! I have a W40VR torch which provide 410nm purple light and 365nm UV light (not 2 light in same time). Can you tell me which light mode is better for Ultraviolet Diving? And need I use a yellow or orange filter? Thank you very much!
I wonder if you might fit diving masks with a *flick in* yellow filter? Like a yellow filter that you slide into the mask to filter the blue light out.
If I want to see the microorganisms (biofilm/biofouling) in underwater environment, what kind of lengthwave I need to use (to see with filter and without)?
I heard the night sky used to be very colourful. Especially the stars at night. Thousands of years ago. I assume pollution and artificial light changed the environment
I don’t think unless you would be blind from the sun already cause you are exposed to it everyday just you can’t see it also the harmful would be the solarium lamps if so even for these u wear glasses only for precaution and that’s it
johnsarangel also I forget uv is harmful on high concentration which nowhere is presented might be it like you taking magnifying glass and use it on sun Kind off
The UV light emitted from the dive light is relatively low in intensity and in very short exposure times. UV is only dangerous in extremely high concentrations and long exposures - neither of which are present with the UV dive light.
