Exercise – Focus At Different Apertures

For this exercise, a series of photos taken with a fixed focus point but varying apertures sizes was required.

I chose an unusual carpet in my home that I thought with careful framing and positioning of the camera , might give obvious results, despite the random nature of the carpets’ colour and pattern.

First photo – aperture f/1.8 with the limits of sharpness indicated between the white lines.


Second photo – aperture f/8:


Third photo – aperture f/16:


I think the above does show the effect differing aperture sizes has on the depth of field in an image.
