With the art of taking pictures comes the art of continued learning. We must be able to allow out brains to open up and allow it to see somethings really work in reverse order. We also need to allow our brains to begin to think of light in the forms of Aperture.
Aperture is the main apparatus of allowing a certain amount of light into the camera; then hitting the camera’s sensor.
But as I said we have to understand Aperture in the order of smallest is really largest. And in the reverse of things largest is really the smallest. So let’s dig into the workings of Aperture.
Most DSLR camera kits we get come with a new shinny kit lens with a F Stop or Aperture of 5.6 / 7.0. This lens will only allow a small amount of light to hit the sensor. Also the more you zoom your lens the smaller the aperture is. This means it closes down and allow less light to hit the sensor. This is the reason most people say their indoor pictures are blurry. Really what you are seeing is camera shake.
This brings me to the reason we buy those expensive lenses. You want a lens with at least an F/2.8. You can also pick up a prime or fixed 50mm lens with F/1.8 and a little more money will get you a F/1.4. With these Aperture settings or opening; you allow more light into the camera. This then allows to you use faster shutter speeds. Hence no camera shake and much better low light pictures. If you are shooting outdoors with the bright sunlight, you kit lens should work well. Study the chart below and you will understand that lower numbers of Aperture means a larger opening for light to travel to the sensor.
