As a rule I use a diaphragm of f/16 when photographing plants, because it usually gives the best combination of sharpness and Depth of Field. After taking this picture of Euphorbia pseudoglobosa last Sunday, I wondered what the result would be if I used the lens’s full opening. The result is shown below. Both pictures have their merits, but to me the second one is more interesting as it imparts a brooding atmosphere and a feeling of loneliness. I would be interested to hear your opinion.
