Dslr Guide
First and foremost, we need to cover the 3 main settings you should be
adjusting on your Digital SLR and the relationship they share with one
and other: Aperture, Shutter Speed, and ISO. In the world of
photography, light is everything. These 3 settings control how much
light enters your camera or how your camera processes that light, so
understanding what each setting controls and the relationship between
the settings is critical to taking a properly exposed picture.1) ApertureThink of Aperture as the hole in your camera that lets in light. A
bigger aperture means a bigger "hole" and thus, lets in more light.
Conversely, a smaller aperture will let in less light. Aperture is
probably the most confusing of the 3 settings because the number
(f/stop) used to describe it may seem "backwards" to most people. The
lower the number, the larger the aperture, and vise versa.For example, an aperture of f/2.8 is twice as large as an aperture of
f/4.0 and will let in twice as much light. I've illustrated this below
to help you visualize
