Photography: Introduction to Aperture, F-Stop and Depth of Field

So far I haven’t really discussed photography, one of the things I enjoy doing and something I now do regularly on a professional basis. My blog tends to be about technology and lets face it cameras and photography use a lot of technology. That is why I thought it would be a good idea to share some of the things I know about photography.

In many ways photography has become far more accessible and cheaper, ok so the cameras may not be that cheap but comparable to film cameras. Where you save is in the printing. Digital cameras also open the doors to experimenting and trying new things to see the results instantly.

I thought I would start out by discussing the aperture and how it affects the depth of field, that is how much is in focus in your photograph. An aperture that lets in a lot of light has a shallow depth of field meaning that whatever you focus on not much is in focus in front of it or behind it. If you have a small aperture then more is in focus in front and behind. Examples of this are portraits where you may just want the subject to be sharp and landscapes where you want everything to be in focus.

You can find out more in this video. More videos are on their way about exposure, shutter speed, ISO, filters and more.
