If of super long the Digital Camera Battery highest power photography, the SLR cameras and automatic focus lens mo belong to, 400 mm, 600 mm, 800 mm, as long as the camera point to where, fast focus lens can lock where, for a professional photographer, professional journalists is, must the use of such equipment to adapt to all kinds of complicated shooting environment, to achieve the fast to the moment were about change, sports competition, birds photography, major state activities news reports, are inseparable from these "guns". If economic strength is stronger photography enthusiast for the dishes are interested in photography theme, when first + af SLR cameras of professional photography lens.
However, professional telephoto lenses have four weaknesses, the focal length is not long enough, the weight is too high, the price is expensive, utilization rate is low.
Most people buy the focal length of canon powershot sd30 battery superman professional camera more than 400 mm, when choose 500 mm. During the filming a close birds, filming the sky to the birds, the focal length can also meet the requirements of the shooting, but, if shooting distance is farther anatidae, focal length of the lens to appear a little short.
A 400 mm lens, usually in 6 kg of the weight of the left and right sides, a 600 mm lens also professional about 6 kg, add heavy lens CANON PowerShot S45 Battery protection case, to carry and operation and make it difficult, therefore, many people buy lens photography after the next step is to buy cars, it is hard to carry "guns" world to shoot.
Professional photography lens is expensive, have already is a common thing. A professional 600 mm artillery is ten thousand yuan less three or CANON PowerShot S200 Battery four, six or seven is ten thousand yuan, make the most of the photography enthusiasts can't ShaXiang, dare to try the distant view photography shooting model.
Professional SLR cameras get af lenses USES is narrower, most photography fans after buying opportunity to use is not much, not only resulted the investment of idle, also because use less, experience, not familiar with the performance of the equipment, and can't adequately in surplus dishes lens due level.
The appearance of the measurement card telescope photography, started in the field of photography super dishes photography mode, to CANON PowerShot S400 Battery bring China develops with the a new means of creation.
High quality telescope as a telephoto lenses have five features: "lens" long focal length, light weight, the image quality is high, the price is cheap, utilization rate is high.
After a cinch camera, a minimum of telescope reached more than 1000 mm, and even can be as high as 23000 mm, its telephoto ability is CANON PowerShot S410 Battery far above the traditional telephoto lenses.
A single measurement card binoculars only 1695 grams, get light model digital camera, can reach about 2000 mm lens effect, very convenient to carry and operation.
High quality measurement of card distant view camera quality, ensure the picture taken very, very good.
Using the telescope as telephoto lenses, the price is only 10000 far.
Measurement card either as a telescope lenses, service in photography, is a a very good observation equipment, is the world's top bird viewing equipment, when it and get a camera in telescope camera, more traditional cameras CANON PowerShot SD110 Battery can't function of the realization of the, with one, worth the money.
However, after all, just the telescope photography distant view in the field of photography a form, it absolutely can't replace SLR cameras and automatic focus lens photography technology, and SLR cameras and automatic focus lens photography than technology, the telescope photography still have some shortcomings, such as focusing speed slowly, with pats the dynamic objects are difficult and so on, which is objective existence, do not need to avoid mentioning and worry, photographer if could properly both CANON PowerShot SD200 Battery advantages combined good, it must be taken from very good head, distance, please choose the method of photography far telescope.
As a new super telescope photography mode, the telescope photography have many problems waiting for people to explore, still have great potential to be people to dig, and many unknown people to enjoy the charm waiting.
The composition and slash photography horizontal comparison of the composition 8
Photography slash type composition, although in the visual will not have a sense of stability, but with this composition can appear to have been taken body energy and rhythm, the layout of the slash has a strong line of CANON PowerShot SD300 Battery sight directed, the use of this kind of composition method mountains, automobile, track filming, etc, which not only show the pictures had the sense of direction, athletic feeling, also can enhance the effect of space perspective.
Compared to the horizontal composition relaxed and comfortable state, use slash method of composition may be some tension, make the line of sight unconsciously with the direction of the picture looked cross-court guide.
In the sea waves when shooting a line call, spray pointed formed a slash type composition, this composition just hair can strengthen the picture of CANON PowerShot SD400 Battery depth, will spin visual effect, make it more space feeling, create a three-dimensional picture of a visual scene.
Combined with look up cross-court composition, can make the picture generate a 3 d space effect, enhance your space clairvoyant feeling and stereo feeling, let picture energetic.
