Exposure Composition

by Jamie Nicholson

Exposure Composition is usually done automatically by your camera using its light metering system. The camera measures the incoming light and adjusts the aperture, and shutter speed, to give you pictures with the correct exposure.
Most digital cameras will adjust the aperture first; once it can no longer adjust the aperture to get the correct exposure it will then adjust the shutter speed.
If your camera can be adjusted manually you can use a light meter and set your own exposure and white balance to get the effects that you want.
Color is on a spectrum. The white balance setting tells your camera what objects in your frame is white then the camera itself will fill in the spectrum. The spectrum is determined by the temperature of the light that is given off of each color.

    Here is why having a period sucks. First of all, it is totally taboo to talk about in the public. I could be suffering and feeling ill from cramps, bloating, and any of the other symptoms - it [...]

    This absolutely freaks me out. There is already a lot of great talent out there and then the performers get younger and younger. If you just watch the video I just posted, you will understand. [...]

    I am in favor of doing favors for people, but I often find that the people I am "not as close to" ask for more favors than the people I am close to. Why is that? In general, people are very good at [...]

  • Making Time for Friends
    It is so easy to get caught up in the work life in New York and never make anytime to see my friends. I mean, I wake up at 6am (7am if I am lucky) and then don't get home until 10/11pm. When I [...]
