The Carnivorous Plant FAQ Field Trip Report -

Southern Portugal in 2011

Return to the Trip Overview

A photography lesson:
This photograph serves as a useful lesson in photography. Usually, I shoot at very small apertures--F16 to F22. This gives me a good depth of field. However, sometimes a big depth of field can be counter-productive. I shot this image at F8. Sure, parts of the plant are out of focus (which bugs me), but the background is blurry enough that the plant tends to pop out at you.

On the other hand, this is the same image, but taken at F22. I have set the hyperlink up so when you click it, you should get the image in a new window. Resize the window, and compare the F8 image side by side with the F22 image. You might conclude that the F22 image, while having more detail, is too messy because the plant blends with the confusing detail of the background.
