The Exposure Triangle – In Beginner Speak “The End of Auto Mode”

In previous beginner speak posts I have written about aperture, shutter speed and ISO and how they affect your photos. Understanding each of those aspects of photography is necessary to have creative control over your shots. “So what is this Exposure Triangle?” I hear you ask. The exposure triangle explains how the individual aspects of exposure (aperture, shutter speed and ISO) affect the final exposure of the photo.

What is exposure though?

The technicalities of exposure are rather convoluted and a bit mathsy, however the end result is that exposure refers to how bright or dark your photo is due to the amount of light that is recorded by your cameras sensor. A properly exposed photo should (normally) resemble the brightness of the original scene. A poorly exposed photo will either be too dark or too bright and may contain areas that are so dark or bright that they contain no detail (know as blown out). So how can we control the exposure of a photo? That is where the exposure triangle comes in.

Depth of Field – In beginner speak “The Blury Background”

This is the first in a series of posts where I am going to try to explain some of the basic concepts of photography in “beginner speak”. If you like the concept, have anything to add, any futher questions or want to suggest another topic then let me know. Either add a comment below or email me.

If you have delved into the world of photography you will no doubt have come across the term “Depth of Field” or DoF. If not you’ll have seen some really great shots with the subject in pin sharp focus with a smooth blured back ground behind it. The ability to control and manipulate this affect is one of the most important aspects of photography. Depth of Field is the portion of an image that is in sharp focus. Controling the amount of a photo that is in focus is important for almost every shot from sweeping landscapes, where the whole scene needs to be sharp, to a headshot where only the subjects features need be in focus and anything else would be distracting.

My First Photo

Whilst I was doing my research of whether to by a DSLR or not I stumbled upon (although not via stumble upon!) a fantastic photo blog called Digital Photography School. It had loads of beginers tips and also a forum. In the forum they run weekly photo assignments amoungst other things (I’ll probably post about the wonders of posting in forums later). Participating in these mini challenges is great way to “encourage” yourself to get out and shoot.

It just so happened that the assignment they were running the day my new camera arrived was called “Depth of Field“. From my research I knew that this was to do with the blurry background stuff I knew my fancy new camera was capable of. It was raining outside so I searched the house for something creative to snap away at and found a salt and peper pot that looked like ghostly figures. My plan was to focus on “the salt” with “the peper”¬†looking all ghostly in the background due to the shallow depth of field (blurry back ground). This is what I got:
