ABSTRACT
Good results in IR and UV photography can be obtained using a good single lens reflex (SLR) digital camera. But because in normal color photography IR and UV will greatly affect the results in a negative way, many cameras have built-in IR and UV filters. These filters greatly reduce the sensitivity of the charged coupled device (CCD) or complementary metal oxide semiconductor (CMOS) sensor, making it more difficult to capture IR and UV pictures. Longer exposure is required, as is adjustment for the focus shift. IR and UV filters are very opaque, and thus it is impossible to focus properly by looking through the lens. Mandatory manual adjustment of the focus is essential, followed by filter installation and picture taking. Finally, the use of bracketing for a clear image is critical in order to compensate for the focus shift.
