Last night I completed part 2 of our Understanding Your DSLR Camera course, this is the stage where I teach about exposure and use the exposure triangle to explain the relationship between aperture, shutter and ISO. This article on the ever brilliant Lightstalking site will do it for those of you not in my class last night.
Getting a new DSLR can be quite an overwhelming experience for a new photographer. All the knobs and buttons seem to do a thousand different things (and they do), but the dirty secret of photography is that at its core, knowledge of the exposure triangle is what will make your new DSLR really sing. If you know how the exposure triangle works, then you essentially know the basics of how your photographs will turn out and you can build your skills with the manual functions of your camera from that solid basis.
The biggest benefit of having an advanced DSLR is that they allow manual control over most elements of the photographic process in terms of what’s happening in the camera. But having that control means that it is of great benefit if you know what elements you need to control and what they do. Let’s take a look at the three absolute essentials that make up the exposure triangle – ISO, Shutter Speed and Aperture.
