Continuous Shutter Mode

Fast continuous shooting is used for catching action shots. Action can happen so quickly it can be  hard to capture the perfect shot. Continuous shoot mode allows you to capture many closely spaced photographs so that you can pick the one which best captures the action. In this case I wanted to capture the bubble being blown so I used continuous shoot mode to capture this. I think it worked well and I have experimented with this skill in my photography work also. The most difficult part of this experiment was getting the timing right between the bubble beginning to be blown and the shutter being pressed to begin the succession of shots. After a few attempts I managed to get it right and you are able to see above the growth of the bubble as the quick shots have captured this well.

Aperture

Aperture controls the depth of field. The larger the aperture number, the smaller the depth of field.This means that less of your image is in focus, only subjects closer to the camera lens are in focus as your depth of field is shallower. The aperture is controlled by adjusting the F. number, small F. numbers such as F.3.5 will give you a shallow depth of field while higher F. numbers such as F.22 will give you a broader depth of field. To control the aperture you must set your camera to aperture priority mode. To use small apertures with F. numbers of F.22 you must have good lighting conditions and the shutter speed will be longer. This is because the smaller the aperture the smaller the hole behind the camera lens so less light is let into the image. Therefore, the shutter speed is increased to make up for this and sometimes you must use a tripod as longer shutter speeds allow camera shake to be seen in the final image.
