PHOTOGRAPHY COLLECTION
Photography is the art, science and practice of creating durable images by
recording light or other electromagnetic radiation, either electronically by
means of an image sensor or chemically by means of a light-sensitive
material such as photographic film. Typically, a lens is used to focus the light
reflected or emitted from objects into a real image on the light-sensitive
surface inside a camera during a timed exposure.
PHILATELY COLLECTION
Philately is the study of stamps and postal history and other related items.
Philately involves more than just stamp collecting, which does not necessarily
involve the study of stamps. It is possible to be a philatelist without owning any
stamps. For instance, the stamps being studied may be very rare, or exist only
in museums.
