Aperture and Depth of Field

Although it is very clear the relationship of aperture and depth of field in theory, in practice, we might make mistake when we are in low light condition to open the aperture to the widest so that we can use a higher shutter speed without realising the impact of narrowing the depth of field.

As I come across morning glory on the way to Bukit Timah hill in early morning, I used to take pictures of morning glory with the largest aperture until last Saturday. After reading some article, realising my mistake, reviewed all the old photos taken before, all were taken with very shallow depth of field, I took this picture with smaller aperture.
