DSLR-Digital Single Lens Reflex
In this the path of light is travel through the lens(way of aperture) to the mirror ,this mirror is placed at an angle of 45 degree.that the light source is turns perpendicularly and reflect in the pentaprism, that prism will shows the image to a view finder.also that mirror is movable up and down.
During the time of pressing the shutter button of the camera that mirror is moves upward and the light source is directly absorb by the sensors.the sensor is placed back to the mirror.
Basically they are in two type that 1.Filmed SLRs, 2.Digital SLRs
1.Filmed SLRs:
In olden days the storage in the camera is in the film role.that stores the images in the negative format.then that negative formats are digitalized to convert them in to the colour image.
2.Digital SLRs:
now a days the storage in the camera or other machines are digitalized in to the micro chip (SD cards)which are easy to use and the developing process made easy with it.and they can also stored the lot of data than the film roles.
