So, you've bought a camera. But there's this teeny little problem about the whole thing: you do not know the first thing about cameras or the principles it functions on! Not to worry though, this article is here precisely for that purpose. To guide you through the basics of photography without sounding like a lecture in Physics. First things first, the camera is basically a device that captures the scene in front of you, using the same principle that applies to your eyes. Light enters your eyes, passes through the lens and forms a image on the retina.
Now, just hold that thought and think about the following points:
• Aperture: This is nothing but the function of the camera that regulates the amount of light coming in the camera. Think of it as your iris which adjustments according to the light outside. Do not you experience a blackout of sorts when you enter a dark room from a bright lit area? That's what happens when the aperture of the camera is inappropriately set. So, lower the light, higher the aperture.
• Exposure: This is the amount of light that is allowed to fall on the film / sensor. Not much to explain here, but the correct manipulation of exposure can do aesthetic wonders for your photographs. Exposing your sensor for a long period, results in, more light falling on your sensor, making your picture brighter.
• Shutter-Speed: Simple. The camera is your eye. The shutter is your eyelid. It's that easy. How to adjust shutter speeds to get awesome effects? Keep it fast if you want stop-motion photos. For example, sweat jerking off a footballer's forehead as he kicks the ball. Or, keep it slow if you want a blurry effect.
• Lens: Every camera has a lens. Digital, SLR, mobile phone, you name it. They are the basic components of the camera and can be very helpful in defining your particular style of photograph. If you're a sports photographer, use a telephoto; for landscape, use wide angle and so on.
• Depth of field – could be used to describe sharp focused area in a photograph. We can shoot either way area focused is sharp focused and foreground and or background are blurred While we also choose to take a photo where every element is sharp and crystal clean
These were just the basics of photography. Although reading it does not make you an expert, it sure will help you in understanding what those buttons on your DSLR are used for!
