Effects of Aperture
Manipulation of depth of field is a good way to modify
the characteristics of your photo, and manipulating the
aperture is the ideal way to do this because it has
little or no effect on composition. You simply need to
change the shutter speed (or change the light
sensitivity, ISO setting) to compensate for the changes
in the exposure from the adjustments to the f-number.
Changes in distance and focal length also affect DOF, but
these changes have trade-offs in terms of composition.
Understanding aperture -- and how it can help your photography
"Photographers know that one of the characteristics that
separates photographic imaging from drawing or painting
is the matter of focus".
"The lens introduces an opportunity for selectivity in
image-making, portraying objects in the near field and
background with a special kind of de-emphasis: out of
focus. Observant photographers have noticed that not all
lenses are created equal: large aperture lenses show
strong out-of-focus effects while small-aperture lenses
lead simply to a softening of the image. And even among
lenses of equal focal length and aperture, there are
differences. The Japanese apparently refer to the quality
of the out-of-focus image as 'bokeh'. What is bokeh, and
why are lenses different from one another"?

Lost your Photo Mojo? Ten Tips to Bring Back the Magic
You really can challenge yourself to try new things in
photography. There are enough linked resources in these
handouts to last years.
One goal is to know your camera equipment well enough to
keep the camera from getting in your way, so you can
concentrate on the composition, perspective and lighting.
