HQ-Cam(TM) Security Surveillance Box Camera - 1000 TV Color Lines High Resolution 1/3" Sony Super Chip CCD With 2.8~12mm 2 MegaPixel Lens For Day Night CCTV Home Video Security In a full spectrum conversion, the camera's internal hot mirror is removed and replaced with a clear glass filter. This makes the camera sensitive to UV, visible, and IR light. This is a great option for someone who does not want a camera devoted to IR. By using various external filters, the camera can take pictures of regular light, infrared light, UV light, or any other combination of these. Most hot mirrors also have an anti-aliasing filter built in, so by removing this filter pictures will be sharper. Please note that not all cameras are capable of accepting external filters. Normally, infrared with a digital camera is taken using an external filter that blocks visible light. This is counter productive since digital cameras have an internal filter that blocks infrared light. As a result, there is very little light getting to the sensor so taking pictures requires a tripod and long exposures. With a fully converted full spectrum camera, the camera's internal hot mirror is removed and replaced with a clear window that allows all waves of light through. This makes a camera much more sensitive to infrared, uv and visible light allowing handheld shots to be taken with normal exposure times and low ISO. There is no more need for filters in front of the lens, allowing for easy composition and lens switching. A converted digital camera is the only way to take good digital infrared portraits as the subject no longer has to stay perfectly still for a long exposure. By converting the camera from within, you can use the autofocus feature of your camera and install various isolating filters to the front of the lens. Infrared photography has a strong appeal for fine art photography. Infrared photography looks very surreal and otherworldly, with trees taking on a bright white or yellow hue, and skies a red or blue hue. Leaves appear frozen over and skies take on dramatic colors in both black and white and color photography. Infrared photography is also a very usefull tool for a wedding or portrait photographer. Skin looks much softer and most blemishes dissapear. For portrait photography, you can imagine the difficulty of trying to take a picture with a long exposure, but with a converted camera, infrared photography is as easy as taking a regular photo, just compose and shoot with no blocked viewfinder or long exposures. Besides the appeal for fine art photography, infrared and full spectrum photography are used in other fields. Many materials and dies do not look the same in visible light and infrared light. This can be used to spot camaflouge, spot counterfeit money, and see through spills for document recovery. Full spectrum photograhy is popular in the field of physics for taking pictures of the stars as some stars are only visible when viewed in the IR or UV spectrum. There are also countless other applications for full spectrum photography including biological plant population survaillance, medical applications, forensics, paranormal research, greater light sensitivity for low light shooting, game hunting, as well as many others. Because of the desire to focus our view into the invisible light waves, full spectrum cameras allow for photos to be captued within light that we cannot normally see. Research suggests that the spirit world may reside or cross over into these frequencies when manifesting either by accident or for that purpose. UFO researchers have found that many unidentified flying objects may be cloaked within the IR spectrum and therefore invisible to the naked eye.
