Adaptive photography

People with disability require different skills in photography. They search for cameras, preferably compact digital cameras, which they can operate independently. For instance, a quadriplegic, spinal injury patient who has neither finger nor wrist movement is able to hold the camera up and look through the viewfinder but cannot press the shutter release button. In the past, a Ricoh film camera was used with the timer function. The timer switch was a little slider button that was raised above the body of the camera and could be clicked on even with the use of teeth. Once it was triggered, there was a 10 second delay and the camera took the shot automatically. Today, the Ricoh film camera is replaced by a more technologically advanced digital camera for use by disabled. Among those, the SLR (Single-Lens Reflex) camera or DSLR (Digital Single-Lens Reflex) cameras are the best choices. These cameras use a movable mirror placed between the lens and the film to project the image seen through the lens to a matte focusing screen. Moreover, the basic criteria for use of such digital cameras is different than those for ordinary use. As for CCD, Charge-coupled device, an electronic light sensor used in digital cameras, the patient should use between a 6-17 Mega pixel. The camera preferably should have an ISO, International Standards Organization, range of 50-800 and a LCD screen size between 1-2.5 inches. Since using a timer switch is really not suitable, these cameras must have automatic switches. Consequently, several companies have developed their products customized to these criteria. The best sellers are among Canon, Nikon, Panasonic, and Olympus. Of course, additional features on SLR or DSLR cameras add to the price and durability of the device. For example, an infrared remote control is a unique feature which controls the shutter release. In this case, the shutter release is more of an electrical than the mechanical feature. In Olympus E20N, the back side of the camera turns upward so that it could be used as a view finder. This would save a person from holding the camera up at the eye level. Olympus has also managed to develop digital imaging Integrated Circuits(IC)'s with a view to the Original Equipment Management (OEM) market. To achieve this, Olympus has been using a technology solution called Adaptive Computing Machine (ACM). ACM is the only software-programmable, real time adaptive IC that offers high performance, low power consumption, low cost, and architecture flexibility in a single chip. ACM program is a deal between Olympus and Quciksilve Company. Canon 5D uses infrared such that the flashes could be set up around a room and fired from the camera. Nikon Coolpix P1 & P2 has Wireless Fidelity (WiFi) Built in option. The Coolpix P1 and P2 (five and eight Mega pixels respectively) have a built-in 802.11b/g WiFi module which enables them to communicate directly with PictureProject and not to standard FTP servers or across the Internet. This wireless connection can be used to transfer all images on the cameras storage card or in a 'live' situation where each image is sent back to PictureProject on the fly.
