The camera aperture is one element in the camera which perhaps has the most effects on your picture. Here’s a collection of some of these effects caused by the lens aperture. So the next time you use a wide or a small aperture, know that you are not changing the exposure.

Bokeh and depth of field, both the techniques help the photographers in creating beautiful photographs. In the approach of photographing at lower f-numbers, the distinction between depth of field and bokeh vanishes and the hobbyists and enthusiasts often end up using the terms bokeh and DOF interchangeably. To photograph the aesthetics of the subject and the background, one should be clear about what DOF and bokeh stand for. To effectively use the two techniques, let’s have a quick view at depth of field, bokeh and the differences between the two.

Focus stacking is a technique used to increase depth of field in a shot with post production. This works especially well for shots using long lens and in this case, a macro lens. Let’s go back to some photography 101 here. There are three factors that will affect depth of field or ‘bokeh’:
1. Focal length. Essentially the longer your lens, the more shallow your depth of field is.
2. Distance to subject. The nearer you are to your subject, the shallower your depth of field is and it very much applies to macro lens.
3. Aperture settings. The more you open up the aperture of your lens, the resulting image has a shallower depth of field. This, however, does not matter as much where the photo above is concerned.
I am a Adobe Lightroom user myself, but this latest version of Aperture 3 from Apple sure looks great!
