Assignment #2A Depth of Field and Focus

Depth of Field and Focus 

As you have learned in your lecture, depth of field is the area, from the near point to the far point, which will be in focus in your photograph.  This can be used in many ways to make your photograph have more impact, to isolate the subject from a distracting background or to give a photograph more apparent depth.  Just to review:

1.  Depth of field is directly related to the f stop which you use.  A small f stop like f 16 will give greater depth of field (more in focus), and a smaller f stop (like f 2.8) will make the depth of field shallower.

2.  When you want fairly accurate indications of depth of field, you should use the depth of field scale on you lens.

3.  Focusing on a subject close to the camera will give less depth of field than focusing on a subject farther away.


 Assignment:

1.  Make at least 2 photographs which show shallow depth of field.  Remember to use a wide f stop (like f 2.8).

2.  Make at least 2 photographs to show great depth of field.  Use a smaller
f stop (like f 16)

3.  Use the remaining images to show subjects in background out of focus,
objects in foreground out of focus, and other variations of use of limited and expanded focus.

Critique is FEB 15



 Don’t forget, as you change the f stop, you must compensate the exposure by also changing the shutter speed.  In some cases, it will be too bright to use a open apeture like f 2.8, or too dark to use f 16.
