Assignment Day 5 Depth of Field | Still Life

The purpose of this assignment was to explore depth of field and how it is effected by aperture setting.

  • Wide depth of field is achieved using a small aperture (large f/number e.g.  f/22). Less light enters the camera.

  • Moderate depth of field is achieved using a medium aperture. I applied a photo quote, “f/8 and forget it!” It’s suggested to use this as a go to setting when depth of field isn’t a deal breaker.

  • Shallow depth of field is achieved using a large aperture (small f/number e.g. f/2.8). More light enters the camera.

 


Some more things to consider when making Depth of Field decisions:

If I want a blurred background, these are some other factors that come into play:

  • Focal Length: long focal length gives the ability to zoom in more on something and that makes it easier to achieve a shallow depth of field.
  • Subject to background distance*: more distance between the subject and the background helps to achieve making the background blurrier. The same is true if more distance is put between objects they will fall out of focus with each other faster than if they were closer together.
  • Subject to camera distance: getting closer to the subject will cause the depth of field to be shallower.
  • Camera sensor: the sensor in my camera also has an impact on depth of field.

*The photos that follow are from my first try with this lesson, the objects were placed close to the back splash of my kitchen counter. The photos posted above show the objects placed further out; I think the depth of field is noticeably improved by moving the objects away from the wall.

Note for All photos: focus was on the frog’s lips.

  1. Thank you, Tracy. I wonder when lots of detail becomes clutter. It helps to learn about your preference and to see how composition is seen by others. Isn’t photography fun? 🙂

  2. Well-illustrated, JANE, and I like your still life. I like that header photo a lot, even though the second shot, the first one after the post starts, shows everything and looks good, too. I know sometimes I want the focus on one thing while at other times I want the entire picture in focus.

    1. It’s been helpful to have these practice assignments to analyze how depth of field is impacted by camera settings. I appreciate your thoughts, Janet. I always marvel at how you seem to stay on top of posting and commenting. As you can see, I got behind on replies, again.
