Minimum Depth of Field- Techniques Page

To achieve minimum depth of field the aperture must be set to large. When adjusting the aperture, you have to consider the f number. As you have a larger aperture, you need to lower the f number. You must ensure that the shutter speed remains high in order to capture a
sharp image with the right depth. When you are shooting it is beneficial to have the subject closer to the camera. The closer the model is to the lens means a shallower depth of field can be achieved. Also, the model had to be positioned further away from the background for depth of field to be achieved. When capturing the image, allow your camera to focus onto the person that you are photographing and then adjust to your liking once the focusing has completed. The result should be a blurred background with a sharp subject in the foreground.
