DSLR Intro - Aperture

Just over a month ago I picked up my first DSLR camera. Boy I sure was excited! Did I have any idea how to use it? Or what an f-stop was? NOPE, no clue at all. 

Over the past month I have learned  the ancient technique of photo-fu and I am willing to teach you too. SO HERE WE GO

The first topic is going to be on one of the the three main aspects of photography: the aperture. The other two are the sensor sensitivity (ISO) and the shutter speed (clicky thing that makes "camera" sound).

Aperture

the bigger the f stop number the smaller the aperture

the bigger the f stop number the smaller the aperture

Aperture is a pretty simple concept. It is the mechanism that determines how much light is let onto the sensor. If you're looking for that "blurry background" effect (this is known as the bokeh) you will want a bigger aperture. The number that determines the size of the aperture is known as the f-stop number. The lower the f-stop the wider the aperture.

Portrait shots such as the one below benefit from having a big aperture to keep attention on your subject, and keep the background out of focus

Handsome looking fellow no? I think so!

A smaller aperture would be good for landscape photography where you are wanting to keep the entire view in focus and no focus on one particular subject. Keep in mind though that having a smaller aperture is going to let less light in. You will have to compensate for that by adjusting the sensor or the make the shutter speed longer.

That will conclude this first lesson in aperture I'll be repeating myself often so don't feel worried if you don't understand quite yet! Also please leave your own pictures or any questions you may have in the comment section below!
