Depth of Field Pt. 1

In your own words, explain what depth of field is. What is deep depth of field?  What is shallow depth of field?  What might you use it for in a video?

    Depth of field is the focal length where the image is in focus, i.e., the area in front of the camera where a subject can be clear and sharp. Deep depth of field is when this area is large, which can allow things both near and far from the camera to be in focus. This can be achieved is by increasing the f-stop. Shallow depth of field is when the range that a subject can be in focus is smaller, which can create a cinematic look with an out of focus background and clear subject. This is done with a lower f-stop. I can use it for my videos to create more filmic looking images and/or to show or conceal different elements in the frame. By having the shallow depth of field, it increases the visual aesthetic of the image. A usage that can enhance the storytelling is by using deep and shallow depth of field to conceal and reveal parts of the image to direct the audience's attention. For instance, if there is something important in the background, I could either shift focus with a shallow depth of field to make it the subject, or I could use a deep depth of field so both the main subject and the background element are in focus.
