in the eye of the beholder

Lately, I have had several people ask me questions about the camera. How do you change the exposure? How does the camera know how much light to let in or to not let in? How do you make the picture darker or lighter? These are all questions dealing with the exposure, specifically the aperture of the camera.

I remember when I first started learning about the camera, I was so confused by the concepts that one must learn about if wanted to take great shots. I even dropped the photography class at Ouachita because I was so overwhelmed on the first day. One concept that is particularly hard to grasp is apertures and f-stops. While I will be the first to admit I have a LOT of learning to do, I thought I would provide some information that I wish someone would have provided me with years ago.

On aperture.

According to Wikipedia.

another tidbit. (I'm a visual learner, so it really helped me understand when I compared an aperture to a pupil.)

The aperture controls the amount of light that reaches a digital cameras sensor. An aperture acts much like the pupil of an eye that opens wider as light decreases to let in more available light. The pupil gets smaller when light increases to reduce the amount of light entering the eye.

Anyway, this is just a little bit of information to help you get started. I hope this helps even a little bit.
