Photography 101 - Tips and Editing Techniques

Understanding Exposure

Last night was my first Photography Basics Class. It was a 2 hour class that passed me by in a blink of an eye. This class was absolutely amazing. I assumed since the class was called “Understanding the Basics” we would start off with what the dials mean on your camera etc.  After everyone knew that we would move on to the exciting information, but I was wrong we dived right into Understanding Exposure!

But first we talked about the proper technique to hold your camera (which apparently I didn’t know)

How to hold your camera:

The position of your right hand
should grip the right side of your camera – forefinger lightly above the shutter release. This part I was doing correct….

The position of your left hand should sit under the lens holding the weight of the lens. So you are cradling the lens in the palm of your hand. I was cradling the lens with the palm of my hand to the left of the lens.

Moving on with the class we talked about how the SLR (Single Lens Reflex) works, but I will have to write about that when I understand it a bit better myself. I thoroughly enjoyed talking about how the components to the camera work, how the shutter opens, how lights hits the sensor, what a sensor is.  But I would have a hard time repeating what I learned so I will do a little homework on that subject first!

Understanding Exposure The amount of light that hits the sensor or film.

Exposure is such a huge topic, but I learned a few things that were great in helping understand the mysteries to exposure. The key to controlling a photographic image is Understanding exposure.

Exposure is determined by two things

  • The amount of light in the scene.
  • The speed of your sensor ISO – (International Standard Organization)

Exposure is controlled by two things:

  • Shutter Speed
  • Aperture (f-stop)

Exposure in photography are measured in values called stops. Stop is a term you will hear again and again in photography only today did I actually understand its meaning (well almost understood it still pondering everything he said about it). A stop is defined as double or half the amount of light.  You can describe a stop of light in two main ways, f-stops and shutter speeds
