Ultraviolet Photography

The universe offers many objects that are “more than meets the eye” because the human eye perceives only visible light and that is a mere fraction of the spectrum available. What lies beyond visible light are infrared and ultraviolet lights and through the use of ultraviolet photography and lenses, more of the universe can be made visible. Photographers enjoy the options that ultraviolet photography opens to them but understand that ultraviolet photography requires unique techniques to master. Under the umbrella of ultra violet photography there is the choice of UV or UV fluorescence photography.

What are UV Photography Options?

The process of reflected ultraviolet photography utilizes lamps that emit ultra violet light that illuminates the object. By placing a specialized filter in front of the camera lens, the visible light is blocked and the UV light is allowed to pass through. The filters are manufactured using specially colored glass. Photographers find the UV filters an effective way to block visible light, allowing the subject to be illuminated with UV rays only.

Another viable option for UV photographers is to use the ultraviolet induced visible fluorescence technique. This is typically used by archeologists but other photographers utilize this technique as well. With the UV induced photography, the same UV light emitting tubes are used but the filters are used in a different manner. When taking photos with UV fluorescence a glass filter blocks and absorbs the light source. Because the visible light is blocked by the filter, only UV light passes through.

The choice of equipment needs to fit the object being photographed. Many standard SLR digital cameras can be fitted to use an infrared light blocking filter. With this filter, photographers can take advantage of the full spectrum of light available. Ultraviolet photography is used by photographers in archaeological settings, crime scenes and by those capturing images of the planets.

Ultra violet photography is able to unveil that which was previously unable to be seen and this is why the technique is beneficial in both scientific and medical research applications.
