Hi guys this is Andy the tech guy in the group i keep being asked about FULL SPECTRUM CAMERAS so here is the answer... One issue with Full-spectrum photography in either film or digital photogrqaphy is the chromatic aberration produced by the wideband information. That is, different spectra, including the ultraviolet and infrared, will focus at different focal points, yielding blurry images and color edge effects, depending on the focal length used. It is important to note that while the converted camera sensor is capable of recording in both the ultraviolet and infrared region, when mixed light hits the sensor it will be the longer infrared waves that will predominate in the recording. Little or no shortwave ultraviolet light may be recorded unless selective filtering is applied to cut some or all of the infrared light. The longwave infrared light may also wash out a considerable amount of the visible light in the blue and green areas in a full spectrum photograph. Similarly if infrared light is entirely blocked, the visible light can overwhelm the recording of the ultraviolet light. So there is no truly full-spectrum photograph that can be made. SO ARE THEY WORTH THE MONEY yes if you buy one from makes like canon nikon anything else is a total waste of your time and money rule of thumb if it cost less than £500 its junk
