Camera controls

Today in class we learnt about the different camera controls and lens functions to create various different effects such as deep focus, shallow focus ect.

The F Stop is a measure of the size in the opening in the lens, which affects the amount of light that can pass through. The smaller the F stop the larger the lens opening- large f numbers relate to small openings/apertures in the lens. Below is a diagram of the f stop function:

We also learnt how to pull focus, pulling focus means shifting the lens to keep a subject sharp. You do this by using the focusing ring at the front of the camera lens which moves the lens elements inside the lens. pulling means shifting the lens to keep a subject sharp. To pull focus a the camera needs to be on manual focus (m) rather then auto focus (af) to engage the focusing ring. 

Below are the examples of our groups practice of using the camera, we have included shots using the f stop to create deep and shallow focus and a short clip in which we pull focus over the duration of it
