Photography is the art of capturing images with light, the actual meaning of the word comes from Greek and means “drawing with light”. This art has been around since the discovery of silver nitrate, although its origins go back to ancient China.

Today it is really easy to take a picture, you just have to take out your mobile phone and that’s it. However, does that make you a photographer? To be quite honest the answer is a big fat “NO”. But that doesn’t mean that you can’t become one and a very skillful one too. You must start with the basics.

If you can start learning with an analog camera that would be ideal, but if it’s an expensive option you can learn with a digital camera. First, you must understand how a camera works and identify all the functions your camera has. You have to understand the concept of “exposure”, this represents the amount of light you let in to the digital sensor. If it’s too dark it’s an underexposed image and if it’s too bright, it’s overexposed.

You can manage exposure through three different settings: aperture, shutter speed and ISO. The first one is the hole within a lens which lets the light enter the camera. You can open it wide for more exposure or shrink it. However, this will also affect the depth of the image.

The second is the shutter speed which means how much time you let the light get in the camera. If you take more time, more light will enter and it will be brighter but it might get motion blur. The ISO is the sensibility you want your camera to catch light, with a major sensibility you can take pictures at night but you won’t get good quality.

These are just some of the basic principles of photography. Understanding this, you’ll get better pictures if you practice enough.



  • Nitrate: A chemical that includes nitrogen and oxygen, often used as a fertilizer.
  • Shutter: The part of a camera that opens temporarily to allow light to reach the film when a photograph is being taken.
  • Lens: A curved piece of glass, plastic, or other transparent material, used in cameras, glasses, and scientific equipment, that makes objects seem closer, larger, smaller, etc.
  • Depth: The distance down either from the top of something to the bottom, or to a distance below the top surface of something.
