The DSLR camera is better known as an SLR camera. The revolutionary invention of the camera dates back to 1861 that has been very successful with photographers. The hefty price and weight of this type of camera had been quickly accepted because of the advantages that this technique entailed.
DSLR camera is the star when it comes to shooting professional photos and videos. This is among the most used camera for youtube videos so that it comes out professionally to the eyes of the viewers.
What is a DSLR camera?
The abbreviation stands for Digital Single Lens Reflex. So the digital single-lens reflex camera. Even before the digital age, SLR cameras existed, the D came later. When the SLR was invented, it was a sensation, you could see exactly the same image through the viewfinder as the final result in the photo.
An improvement on a separate lens in the viewfinder, which gives a different picture. Since the SLR, photographers have the feeling that they really have control over the image they make.
The trick is in the mirror on the inside of the camera. This mirror reflects (“reflex!”) The light entering through the lens through a prism to the viewfinder and therefore to your eye. So you really see the image coming in through the lens. When printing, the mirror pops up and the light goes directly to the photosensitive film or sensor.
The result is that the viewfinder momentarily disappears when printing, the mirror is temporarily switched off by folding up. That is a disadvantage … A second disadvantage is the sound that the folding mirror makes when printing. Shy animals cannot appreciate this and leave quickly.
Nowadays you also see DSLR cameras appearing with a mirror that doesn’t fold up but stays in place when printing. The secret is in a translucent mirror technology (translucent-mirror technology), which reflects a small part of the light to the viewfinder and transmits the remaining light to the sensor. So you can still print and still see the image at the same time.
Really handy if you photograph a flying bird and you print at 10 images per second. You can keep the animal constantly in the viewfinder. There is also a disadvantage to this method. Because part of the light deflects towards the viewfinder, you lose about 20% brightness on the sensor, corresponding to about 1/3 stop.
