D&D Yellow Barrier Filter 67mm
For fluorescence photography you need a barrier filter in front of the camera lens. This filter has two jobs
block the reflected excitation light
transmit the fluorescence
and it needs to do both with high efficiency. NIGHTSEA provides barrier filters that are well matched to our excitation sources. There are options for filter material – glass or plastic – and how you apply the filter – inside or outside the housing.
Glass filter in a holder with standard filter threads. Screws into your camera lens inside the housing, or outside if your housing has a thread adapter.
Acrylic filter sheet that attaches outside your housing with bungie (elastic) cord.
Putting the filter on the camera inside the housing protects it from the elements, but you can’t remove it during the dive to switch back and forth between fluorescence and white-light photography. Putting the filter outside the housing gives you the option to switch back and forth, but with the need for care to avoid scratching or breaking the filter.
The glass filters are available in all standard camera thread sizes.
The numbers after the BB refer to the standard filter thread sizes in mm.
