Digital Macro Photography
The phrase "digital macro
photography" normally is used in reference to photographs taken close-up
which means that the
image projected on the digital sensor film is the same size as
the object which is being photographed. Macro photography has the
purpose of making
small objects appear to be larger. Sometimes the term micro photography is used instead of macro.
The terms mean the same thing. The subject of a photography in marco photography is something that is small but
that can be seen with the human eye normally. Flowers, small birds or
animals, snowflakes or even insects are popular subject for macro
photography.
Depth of
field, or rather the limited depth of field is an important
consideration in this type of photography. Some camera models are able
to focus in such close proximity to the subject that the subject may
even touch the glass lens of the camera. This can sometimes cause
lighting difficulties such as with a 50 mm lens. Using a telephoto lens
may be the best option to avoid this. A telephoto lens provides lighting
distance between the camera and the subject of the photograph.
A recent development is use of ring
lights which use white LEDs to provide light. For macro photography, you will need
bellows, sometimes called extension rings that fit your brand of camera and
your lens mount. The rings are attached between the camera
lens and the camera body, so you will need a camera which has a
detachable lens. An SLR camera works best for marco photography.
Many camera companies manufacture
and sell "Macro Lenses". Macro lenses are often expensive. They usually
have a smaller maximum aperture than a standard lens. Nikon's 60mm macro
lens is only f/2.8 for example. Macro lenses are usually also bigger and
heavier than standard lens.
