t is a well-known fact that aperture is one of the three variables used to control the camera’s exposure. But, it is also one of the most useful variables for creative nature photography. Beginner nature photographers are so focused on using aperture for controlling depth of field and exposure that they often ignore the creative aspect of the using aperture.
And who can blame them? It is not easy to use aperture as a creative variable. Using aperture as a creative variable requires out-of-box thinking and bit of experimentation. Here are some tips for using aperture to capture creative nature photos.
#1: Play with Depth of Field
One of the first things you learn is that aperture can be used to control depth of field. And this property of aperture is very useful to simplify your photos. To use this effect for nature photographs, you must select your focus carefully.
In the first image above, I used an aperture of F13 to get the trillium flower sharply in focus. However, by using this aperture, I could also include the cluttered background in the image even though the focus was carefully set on the trillium flower. Now compare this with the second image above where I used an aperture of F4 to capture the same flower. Here the background clutter is greatly reduce, but so is the depth of field. For this image I carefully selected my focus to be on the stamen of the flower even it this meant that only part of the flower is in focus.
You can also combine selective focus with narrow DOF field at wide apertures to isolate a single element from its environment.
