Framing (or cropping) is a facet of composition that, in the basic sense, encompasses good scale (the relative “size” of objects in the picture, or how much space they use), angle (how you hold your camera), etc.
The aperture itself is the opening in the diaphragm that controls the amount
of light passing through the lens and onto the film or sensor. The size of the
aperture is referred to as the f-stop and it relates directly to the depth of
field, which is the distance between the nearest and farthest parts of a scene
that appear in focus, or the focal length divided by the diameter of the aperture.
We've all been there. Spent a lot of money to go to someplace we've never been before. We've taken the photos and brought them home expecting family and friends to ooh and aah over the shots we've taken. You open the envelope and take out the prints and somehow the landscapes and nature shots that looked so beautiful there look flat, dull, and you don't remember seeing that couple in the corner of your shot when you snapped the shutter.
The digital cameras are the standard camera today. The difference between a classic film camera and a digital camera is that the digital camera is using a sensor to capture the light instead of film. This makes it much easier to use the camera for many different things.
