I can't really complain that the only subject I've photographed to day is a fox (Cheeky, of course), but to make the blog a little more interesting I've selected four shots which illustrate the use of different aperture settings on the camera. All the shots were taken from approximately the same distance (6 feet). To cope with the different apertures I did alter shutter, ISO and flash settings. I've included the relevant camera info with each shot. The flash was consistently set to 1/4 power (manual), but I dropped the diffuser over the flash for the large aperture shots to reduce the amount of direct light.
As you can see, the use of a small aperture (confusingly designated by a high aperture number (f/13)), produces a deeper depth of focus (more of the image is sharp). The small aperture lets less light into the lens, hence I needed to raise the ISO (sensor sensitivity) and reduce the shutter speed (to allow more time for the light to enter). The large aperture (sometimes described as 'wide open') has a small number (f/2.8 in this instance), lets much more light in (hence the low ISO of 100, and high shutter speed), and creates an effect where the focusing point is sharp but the rest of the shot is 'soft' or blurred. You can see this clearly in the second and fourth shots where I focused on the tip of Cheeky's nose. For reference, I usually shoot at around f/7.1, mid-way between the settings used here.
Shutter 1/60s, Aperture f/13, ISO 200
Shutter 1/200s, Aperture f/2.8, ISO 100
Shutter 1/60s, Aperture f/13, ISO 200
Shutter 1/200s, Aperture f/2.8, ISO 100
Camera note: all shots taken with the Canon 40D and EF 100mm f/2.8L macro IS USM lens.
