This was a beautiful wedding. It took place at the Birdhaven Greenhouse in Joliet, IL. It was a chilly autumn day towards the end of the leaf season. We went to a small forest preserve and this is one of the shots that was taken there.
You will notice that the leaves in the background are out of focus. This allows your subject to pop. This is achieved by the correct use of the f stop or aperture on your camera. Your f stops show on a ring around the lens on your camera and run from 1.0 to 32, lenses vary in the starting and ending points for f stops. Generally the smaller the number (1.0) the more expensive the lens as this can be used in lower light situations. There is a diaphragm inside each lens and the smaller the f stop the larger the opening is on the diaphragm. This allows more light in.
The aperture not only affects the amount of light that enters the camera, it also affects the look of your photo. The smaller the number-1.0 (by the way this is considered a larger aperture not a smaller one) the less of your photo will be in focus. The photo above was taken with an aperture of 3.5 had a used an aperture of 16 the leaves would have been in focus and the bride and groom would have blended in with them.
Next week we will talk about the corrolation between f stops and shutter speed,
