Aperture & F-Stops
Your aperture, is, like your shutter, primarily a tool that controls exposure. It's literally a hole in your lens that lets in light. But it's actually far more exciting than that.
Once you understand how it works, you can use your aperture creatively to completely change the look of your pictures by creating soft fuzzy backgrounds and foregrounds.
Your camera has a semi automatic mode called Aperture Priority or Aperture Value (depending on the make) which helps you be creative whilst it works out the exposure for you.
And if you don't understand about f numbers, don't despair - it's all explained here.

7 Steps to Perfect Pictures is a demanding course because it's akin to learning a new language. Even if one masters the grammar that's useless unless the vocabulary comes easily in conversation when it's needed. So for me, the true value of the course was to provide me with the elements that will enable me to become "fluent" over time.
