Raiders wide Macro Photography If there are a number of photographic
equipment and photographic methods, could be a microcosm of the world
to show a true in your eyes, you will be fascinated by this purpose?
Beyond our scope of such a visual way of photography to allow forest
insects, leaves, water droplets defibrase cents is completed,
transformed into a magnificent spectacle. Members know that the thorns
of the bushes as if even the dense forests, small stone like a
mountain, even a small drop on the ground can also become a lake in
general. Excellent photographic equipment with a unique way to show us
a brand new world. This is macro photography. In the popularity of
digital cameras before, macro photography is more often a special kind
of photography as a way for many photographers and experienced
photographers are known to reverse the lens through such means as to
achieve the unique effect of macro photography. However, digital
imaging technology with the rapid development of "macro mode" has
become almost all the standard functions of a digital camera.
Photography skills even know the "rookie", but also enjoy macro
photography can easily bring happiness and visual impact. So, what
macro photography unique? We can see how these beautiful photos
produced? The choice of what kind of digital camera to achieve the
aspirations of the world micro-film? In the course of filming, what do
need to pay attention to? In general, the imaging conditions for macro
photography is close to twice the focal length of the material from, or
even more than twice the focal length. This will be close to twice the
focal length or exceeded twice the focal length. Optical principle as
the most intuitive explanation is that the camera lens to keep away
from the photosensitive surface in order to clear imaging. Digital
camera parameters have been concerned about a friend should be aware
that the focus of a range of digital
acrylic boxed photo frames
usually between 0.5m to infinity, focus at infinity if the distance,
the photosensitive surface of the lens in the distance is the most
recent, and focusing distance of about 0.5m, the lens from the camera's
sensor is the farthest side. If the requested object within 0.5m
accurate focus, it is necessary to allow the lens farther away from the
photosensitive surface. From the above principle, we understand that
the realization of a digital camera macro photography, in fact, relies
on the lens and body to increase the distance between the
photosensitive surface is achieved. Lenses in these cameras usually
have a set of lenses can be flexibly adjusted, when the need for macro
photography, the lens can be moved to the farthest away from the
photosensitive surface of the position, in order to achieve macro
shooting. At present, the majority of the market has a 1cm macro
shooting function of the following digital cameras, most of them are
telephoto camera, but also because non-telephoto telephoto camera
camera lens has a greater flexibility of space, only have a stronger
Macro shooting ability. Macro lens is the same principle, the camera's
lens group further away from the lens than ordinary photosensitive
surface, of course, with the focal length increases, the distance is
far away from large, this will increase the cost of the lens, macro
markets lens than the general price level of an ordinary lens with the
high cost, it is for this reason. Macro photography of important terms
Closest focusing distance: the number of digital cameras in the
parameters, usually set out from the recent focus or focus range, near
the end of the general only 1cm or 2cm. Most of the time we all agree
that the shorter minimum focusing distance, the greater the captured
image, the stronger the ability to close-up. Is this true? Closest
focusing distance has been taken from the past that objects near, so
taken, but this would very difficult to light up. Our macro
photography, it is usually in the shadow of the camera left, that is
caused by this reason. Insects in the shooting when a class of
subjects, such as near-focus distance will create obstacles, the focus
is away from the merits of the past may not be. We can illustrate the
use of Macro mode shooting at close range and use of focal length +
Macro mode shooting, in theory, could make the same macro-sized photos,
but the actual effect is not the same. Macro mode part of the shadow of
the photos there, and there are some corners of the photo distortion,
and the use of focal length + macro mode photos will be outstanding in
this respect a lot.
