It is a good practice to orient the photos so that the shadows are falling towards the interpreter.
Recently, photographers have exploited the shape of the bokeh by creating a simple mask out of card with shapes such as hearts or stars, that the photographer wishes the bokeh to be, and placing it over the lens. [16] Lenses with 11, 12, or 15 blade iris diaphragms are often claimed to excel in bokeh quality.

Likewise, when taking photos looking down, e.g., from a skyscraper, buildings appear to get broader towards the top.
For example, a square can be unambiguously defined by the locations of three of its four corners, from which the software can interpolate the connecting boundary lines and the interior space. Because it is a regular shape, a square could also be defined by the location of one corner, a size (width=height), and a rotation angle.
