MWhat is the relationshipbetween Aperture and Shutter Speed?
Aperture is determining how wide or how small the lens opening will be. Wider apertures (f2.8 and f4) let in more light. Smaller apertures (f16 or f22) let in less light.Shutter Speeds determine how fast the lens opening stays open. Faster shutter speeds (1/250 and 1/500) let in less light. Slower shutter speeds (1/4, 1, and 15) let in more light.
The faster the shutter speed, the wider the lens opening.The slower the shutter speed, the smaller the lens opening.
ManualYOU take full control of the camera.When you dont want the exposure to change from one shot to the next. (Panoramas)I ALWAYS use Manual mode, except in situations where I might need to take a quick photo, or Ill miss the shot. In those cases, I use P (Program mode) and -2/3 exposure compensation.
Why would you use Manual mode?PANORAMAS
Switch to Manual mode (so your exposure wont change between shots)Switch WB to CloudyMake sure your ISO is as low as possibleChoose a small aperture (f8) and press shutter halfway down to set your exposure.Shoot verticallyShoot first and last shot with your finger (so you know when your pano starts and ends.)Overlap each photo by .Shoot 3 to 5 photos quickly so things (clouds, people) dont move too much.
