Photo Friday!

Ok, so here is today's question.

Is there is a quick and simple process to remember in order to shoot the sort of photos that I see on your blog where the subject is in focus and the background blurred?

The simple answer here is to set your DSLR on the Av, or aperture mode, and set it to the smallest f/number that you can. The aperture in your lens acts much like the pupil in your eye - it opens and closes to let a little or a lot of light in. When the f/number is LOW, the aperture is opened wider, to let more light in, and therefore the subject is in focus and the background is blurry. If you set your camera to the Av mode, you can control aperture and the camera will look after your shutter speed for you.

Here are three photos of Ahsoka taken at three different aperture settings. I put a jar of marbles behind her so that you can see how the depth of field (the amount of blur) changes with different aperture settings:

f/1.8 1/100 ISO 400

f/4.5 1/80 ISO 640

f/9.0 1/50 ISO 800

Do you see as the f/number gets larger, the marbles come into focus more and more? The aperture in the lens is closing and bringing more of the whole photo into focus.

Try playing around with the Av mode on your cameras, in an environment with lots of light, and review your results. Good luck!
