Preview is one of the important means photography JVC GR-D240 Battery creation, used in narrative pictures of the relationship between the various scenery. Especially in photographing, often will demand, so as to realize the background picture derived becomes concise and bright.

The JVC GR-D250 Battery size of the depth of field and camera aperture, the length of the focal distance and photographed has close relationship. Specifically, aperture size and depth of field is inversely proportional to the size of the same length, the focal length is inversely proportional to the preview; Shooting distance the farther from the depth of perturbation objects, the smaller, the greater the vice.

Digital camera JVC GR-D250U Battery, depth of field size and imaging of the components is closely related to size. Often CCD/CMOS area is bigger, the better the results. Now many consumption level is higher than the pixel camera SLR cameras, but instead of imaging quality than low pixels SLR machine, such as 900 million pixels of Fuji S9500 a slice quality than 600 million pixels nikon D50.

Many friends for several reasons, can't all go have SLR machines to photography. Besides equipment quality and not the key decision photography JVC GR-D270 Battery, the quality of brushes with calligrapher's can use ordinary unconstrained style, I only can write "dog" is a truth. The consumption level cameras on the market can be divided into card machines and telephoto machine two kinds big,

Card machine for portability through sacrifice performance, and in many ways (including preview falsified) as telephoto camera.

The author USES is SONY H2. Just started, according to the teaching material inside speak ways to test, aperture F2.8, to pull open to more than 400 mm focal length. But on the computer, found only slightly fuzzy background can be falsified failure. Basically, Test effect still many times. Thought is the camera itself the quality question, went to SONY's done testing, the results pit not quality problems. Background can't throw problem has puzzled me for a long time, even on the plan, there were perhaps netizens nicknamed the poisoning. jvc gr-dvm70 battery

1 shot on the balcony, to composition of POTS of 12 times needs to be enabled optical zoom, still USES the camera's flexible point focusing function, focus on the flowers on it. After a shot on the computer overjoyed - "look, it's terribly melt." background After careful analysis, this time I falsified success, large aperture and telephoto need not say oneself, more important is to adopt a flexible point focusing function, and flowerpot in two building background open (more than 20 meters) between later after many practice, j reached some experiences.

1 try to open large aperture and telephoto camera shot as much as 2 main body, when close to open three flexible macro function point focusing or adjust shooting Angle manual focus 4, make the subject is far from the subject. Methods looks be like simple, actually have some problems to solve. In the first click, request the author can grasp the fuselage, camera FangDou stable the important performance is achieved. In the second points to the camera's wide-angle ability, put forward higher requirement, not enough wider had to clap butters did. JVC GR-D370 Battery
