DSLR Camera Software

A DSLR - or Digital Single Lens Reflex - camera is a digital version of the widely popular SLR or Single Lens Reflex camera. The most significant difference between the two devices is that the SLR camera stores the images it captures to cellulose based film while the DSLR camera stores its images to persistent digital storage such as secure digital (SD) cards (See Figure 1). Both devices are targeted at slightly different end users. The film based models of this camera have traditionally been used by those with experience in manually operating a camera. Manual use of a camera requires the user to specifically set the aperture, flash, light sensitivity (ISO) of the film (or sensor, in the case of DSLRs), shutter speed, and choose the lens of the device in order to capture a picture (See Figure 2). The DSLR camera attempts to widen the user base to include not only the professional photographer who is well versed in the operation of the device, but also to amateur photographers and individuals with little to no experience operating a camera.
