The technology of photography has continuously evolved and improved since the turn of the 20th century. The demand for traditional camera that used films has long been decreased.
This is because of the ease that the camera offers for those who are not really into photography.
Technology isn’t only for those who are not into photography; it also offers something to those who consider photography as a profession and science.
Professional photographers find their job and profession easier to manage and do and at the same time more relaxing with an SLR Digital Camera.
The automatic mirror system applies the theory of prentaprism wherein light is directed from the lens through the use of the viewfinder. Its design is completely different from an ordinary digital camera.
An ordinary digital camera exposes the sensor directly to the light which is projected by the lens whereas as DSLR uses its mirror arrangement to prohibit the scene from being viewed on the LCD.
Now, new models of DSLR have a live preview feature where LCD can be used as viewfinder.
If you are contemplating of buying an SLR Digital Camera, you have to take note of its features and operation system. Be aware of its differences from a standard one. Be sure to distinguish which one is good and which is not.
A good SLR Digital Camera has complete features including the unusual ones.
Check if the camera has a mode dial feature for accessing the camera settings. A good one should also have an automatic scene-mode feature.
Check the focal length and sensor size of the camera’s lens. A good SLR Digital Camera has a big sensor. This gives a bigger angle view depending on the focal length. Thus, a good SLR digital camera has a more than average focal length. This type can be more expensive but you will have greater quality of the image.
A good SLR Digital Camera should have depth of field control. It is possible to limit the depth of field. It is not good if the photographer cannot adjust or limit the depth of field because he can’t take pictures where the background is sharpened.
A good SLR Digital Camera should have wide lens. The wider the lens, the greater the depth of field can be and it is easier for the photographer to adjust it to the limit and depth he wants.
