You use these settings when you understand exposure, depth of field, how the shutter speed affects motion capture, etc. and want to chose settings that give the effect you want. Assuming you're using a Canon EOS, these exposure modes also allow the image file to be saved as RAW for more effective post-processing.

How do I learn and understand exposure. I keep buying books to learn but none of them are helping me understand. I am using the camra manual also. thank you for your help.

Kasey Tell us in as few words as posible what you know about: 1. a shutter 2. an aperture 3. ISO and we will teach you the rest.

Ok Kasey, Here we go. Perhaps others will chime in since I have no intention on writing a book. LOL First off; “Program Mode” or what ever Canon calls it is simply the camera making ALL the decisions in regard to shutter speed AND aperture. This mode is OK for snap shots or photos that you have no intent in making artistic. That is not to say Program mode can’t capture a great shot; it can; but YOU have no say in it whatsoever.
Photographers like to adjust shutter speed for a few reasons. 1) A SLOW shutter speed will cause the image to blur if the image is moving. 2) The light is SO bright, you can not get a good exposure. Shooting into the sun for example might require a very high shutter speed. My Nikon will shoot at 1/8000 sec at it’s best. That is a VERY short amount of time to allow light into the camera. 3) The opposite of #1 would be to FREEZE the action. How fast a shutter speed you need to freeze the action depends on how fast the subject is moving. Sports photography uses high shutter speeds to “stop” or freeze the action. Perhaps you want a shot at the instant a football player is tackled and falling to the ground. You will need a fast shutter speed to catch this moment. Maybe 1/250th or 1/500th..The faster, the better.
As your shutter speed increases, (LESS) light is entering the camera requiring you to “open up” the aperture more if your end result is a proper balanced exposure. The reverse is also true. There may be times when you WANT the scene to look dark like night..so you have the ability to turn daytime into night. That is NOT possible in Program Mode as the camera will TRY to figure out a speed/aperture setting for a good exposure. I hope this was not too basic kasey; but I have no idea where you are in your learning curve. I’ll leave APERTURE and Depth of Field to someone else....My fingers are tired! LOL All the best, Pete

Thank you soo much. I needed that, all the books I have been reading didn't break it down like that. I am getting it now. I appreciate all your help. KC

What books did you buy? Anyway, aperture-Works like the pupil in your eye. Light is bright, iris closes down the pupil. Very little light, the iris opens up the pupil to let in more light. Also works like a faucet when you combine it with shutter speed. Barely open the faucet, water trickles out. You wait a longer time to fill up a glass. Open the faucet all the way, lots of water comes out and you only need to leave the faucet open for a short time. Depth of field-small apertures require a long shutter speed. But because the aperture is small, this makes a greater area behind the subject in the photo, and in front of the subject, appear to be in focus. A large aperture, this makes the areas behind and in front of the subject the appear in focus smaller. So, you focus on Jo-Jo, the area that's behind and in front of Jo-Jo is called depth of field. Part of what determines how far in back and in front it is, is the aperture. Next!

Kasey, seems you are trying to take the easy way out & have some hand holding while on photo shoots. You got some great info here in responses. If the books are not working for you, try a class here at BP on Exposure. Jim Zuckerman teaches a great class on exposure. I took it & learned alot. It's worth the money. I learn better from lessons, one on one critiques than I do with reading a book. Oh yea, Zuckerman also has books on the subject. His class is a great one. It is called, "Perfect Digital Exposure."
