When you are a photographer you need the latest equipment you can get. What is the difference between a wind-up clock and a digital watch? One is wound up manually while the other runs on batteries. This difference is the same in the SLR and DSLR cameras.
The Single Lens Reflex (SLR) camera uses optical film to capture pictures and images. The mirror and prism system used in the SLR cameras send the light through the lens of the camera and when the photographer presses the button, it captures the scene. The photograph remains captured on chemical-coated film that you must process in a photography lab.
When you look at an image through the camera, the light undergoes reflection and you get an inverted image. This prism in the camera then flips the image over so that it becomes upright again. So, the photographer is able to see the image like in real life.
When you press the button on the camera, a lever moves the slanted mirror that is present to reflect the light for you to see the image, moves out of the way. This causes the image to project directly onto the film. You might have noticed how things go black for an instant before things become white and normal again.
In the DSLR camera or the Digital Single Lens Reflex (DSLR) camera, the working principle is the same. Only, here we do not have any film. The sensor takes the place of the film and it records the images onto a microchip present in the camera. The bigger the size of the sensor, the better the quality of the image is.
Storing the pictures
When it comes to storage space, the DSLR can store thousands of pictures on a memory card while the SLR can only hold 16 snaps at a time. You must then change the spool and then shoot the pictures.
Shutter speed of the cameras
This is a feature of the camera that affects the quality of the picture. It is the time for which you leave the camera aperture open for light from the image to fall on the film or sensor (as the case may be). When you allow the aperture to remain open for a longer time, more light will enter and the picture will have more brightness.
But, there is one weakness with this. If the image moves while the shutter is open, then the picture will become blurred. Or, if your hand is not steady, then the picture will have blurred images if the shutter is open for too long.
Hiring your camera and lenses
For those who cannot or do not want to buy the high end cameras such as Canon, Sony, or Nikon, there is one option open. That is to hire the cameras. They can get cameras and lenses for a low prices starting from Rs 1,000 per day. They only have to register on the site to have their cameras door-delivered.
Shooting in low light is difficult. The obvious disadvantage is that enough light might not be there. This will make the picture very dark. To overcome this, we use a wide-angle lens that allows more light.
