Depth of Field Pt. 1
Depth of field is like a block of sharpness which extends into your photo. You might need a big deep depth of field for something like a landscape, or maybe a small shallow one for a portrait with a soft fuzzy background.
Aperture size is the main depth of field control - but focal length and how far away you are from the spot you've locked your autofocus onto also makes a difference. As you adjust depth of field with your aperture you must be careful to avoid camera shake - which can happen when you set a small aperture.
In this video exercise we'll work with a wide or short lens because different focal length lenses have different depth of field characteristics. A short lens has lots of DOF. In depth of field part 2 well do it with a long lens which is much better for fuzzy backgrounds because they have a much shallower depth of field.

The 7 Building Blocks of Photography has massively improved my photography overall. It has made me think about how I want an image to look, rather than just going out looking for an image, then get home and be disappointed. My approach now is to visualise, construct it block by block then make it happen. My 'hit rate' has soared.
