One of the exercises we have during the workshops is to make three pictures of the same subject with three different apertures. This to practice working with different depth of field (DOF). In some cases a large DOF can be really nice. This can be the case if you want to place your subject in its natural environment. A narrow DOF can also be nice, e.g. if you have a very small subject and want to put all focus in the subject, or if you want to focus on a small detail of your subject. In this case I wanted to put emphasis on the edge of this White Saddle. So I took a large aperture, resulting in a very narrow DOF. To increase this effect even more, I added a vignette to the image and turned into a black and white. I hope you like it.
