Shutter Speed
Shutter Speed is the amount of time the film is exposed to the light. I set the camera to Manual Mode, adjusted the aperture to 22, set my ISO to ISO 100, and set my shutter speed to 1/1000th's of a second. I chose to have my subject jump. Having the subject jump gives a levitation look to the photo. This tricks your mind into thinking the subject is floating.
Aperture
Aperture is the opening of the lens to expose the depth of field in the photo. I set the camera to AV Mode so I could manually adjust the aperture. Then set the aperture to 1.9 to make the foreground in focus and the background out of focus. This gave a portrait style feel to the photo. Your eyes are automatically drawn to the subject of the photo.
ISO
ISO refers to the sensitivity to light. I put the camera on Manual Mode and adjusted the aperture to 22 and set a 1/1000's of a second for the shutter speed. The flash helped with the lighting on the subject as well. Then chose the lowest ISO (100) and the highest ISO (6400). I chose ISO 400 and ISO 800 for my other two photos.
