Photography is the art and science of recording
images by reflecting and recording light on a light-
sensitive surface, primarily through the use of a
camera. Photography has a range of applications
and is popular as a profession and a hobby. Due
to this, many types of cameras are available
today.

3. Types of Photography Cameras
 - Compact digital cameras - Small and relatively
inexpensive, these cameras are popular among
beginner photographers. Digital cameras are usually
fully automatic and easy to use, but do not provided
the quality or control of other types of cameras.
- Digital single range reflex – Referred to as SLR
and DSLR cameras, these cameras are larger and
heavier than compact digital cameras. SLRs and
DSLRs are manual and therefore offer greater control,
including the ability to swap out camera lenses.
- Mirrorless cameras - Also known as electronic
viewfinder interchangeable lenses, these cameras are
more recent and combine the small size of compact
digital cameras with the manual control of SLRs and
DSLRs.
