Figure 1: The DoF (Depth of Field/Focus) equation.
Depth of Field ain’t so tuff.
Recently I needed to take some photographs of the antique glassware that my spouse collects. This is easy with a point n’ shoot, since its depth of field is pretty good thanks to the short focal length that most point ‘n shoots have in their built-in lenses. The point ‘n shoots usually have a wide angle (anywhere from 6 to 15 mm – but sometimes variable up to higher focal lenghs with fixed zoom offsets).
