Fun With Apertures

So, time to talk about all the things I've learned so far. In particular, three things about apertures.

1) The aperture is the opening which controls the amount of light that reaches the film. The larger the aperture, the more light reaches the film. The smaller the hole, the less light. Pretty simple. Used in conjunction with shutter speed, the proper exposure is achieved.

2) The aperture is gauged using numbers. The larger the number, the smaller the aperture. The smaller the number, the larger the aperture. For instance f/1.4 would be larger than f/8. Confused yet?

3) The aperture is also responsible in controlling depth of field. This allows you to focus in on what you choose. For instance, making a point in the foreground very clear and keeping the rest of the image slightly out of focus.

Now that I know all this stuff, I should probably go work on that aperture photo assignment.
