Power use time

Power use time namely digital camera Battery Charger use original battery can photographs number. Digital camera often can use dry cell batteries, manganese base zinc, nickel cadmium battery, nickel-metal hydride batteries, lithium ion battery and lithium battery as its power. Use the battery as a power supply, not only replace simple, and make the camera and easy to carry, flexible operation, and the battery the scope of the choice is larger.
 
Just buy back of rechargeable batteries jvc gr-dv500u charger generally very low or no electricity power, should charge before use. For charging time, depends on the charger and battery, and whether the use of voltage stability, and other factors. If is the first use of the battery, the lithium battery charge must be more than six hours of time, the nimh batteries must be more than 14 hours, or future battery life will be short. General required to pass through several times the charging/discharging process can reach the best efficiency. And the battery and residual power, try not to repeat charging, to ensure the battery life. Full of electric charge was very hot, should stay after cooling then in camera.
 
Digital cameras jvc gr-d270u charger have electricity ability, if you use a do not match the battery or do not pay attention to save, then the battery in didn't you shoot a few picture fails. The following measures can save battery usage: first, try to avoid using unnecessary zoom operation; Second, avoid frequent use flash, flash is large power consumption, we try to avoid using; Third, in the adjustment of the picture composition of best use when the viewfinder, and do not use LCD. Because most of the digital camera will open for liquid crystal display (LCD) point that consume more power, will close it can make a battery spare time two or three times growth; Fourth, use less as far as possible even pat function. Digital camera even pat function of the most built-in cache to temporarily save digital photos. If often use these cache of words, the electric power very much. Therefore, to reduce the use even the beat and the dynamic image short films function, are of great help for power saving.
 
In order to avoid the loss of the power problem, battery cleaning is very necessary. Keep the battery on both ends of the contact points and the battery cover internal clean and, when necessary, use soft, clean dry cloth graze, never can use clean sex or the chemical has the solubility things clean your digital camera, battery, or charger. If you intend to long time don't use a digital camera, must want the battery from a digital camera jvc gr-d270 charger out, it will be completely after discharge (some charger with this function is not available, such as the small resistance short sub as far as possible the electricity off) stored in a dry, cool and environment, and don't batteries with general of the metal items stored in together. Storage already full of electric battery, must not guiltily, pocket, handbag or other contained metal items in the container to prevent short circuits.

The attention of telephoto shots

Telephoto lens jvc gr-d395us charger is the lens focal length than the standard lens, can be used to capture distant scenery closer, more clearly showing the details of the subject characteristics. Telephoto lenses and telephoto lenses can be divided into ordinary two super telephoto lens. Ordinary telephoto lens focal length close to the standard lens with a focal range of typically 85mm ~ 300mm, while the super-telephoto lens focal length is much larger than the standard lens, usually in the 300, above.

Distant telephoto shots with the birds, the use of telephoto lens shooting JVC GR-DVL9800KR Charger bird landed on the distant fence, close to leaving in order to avoid relying too frightened bird flew away. Lazy bars using a telephoto lens to shoot from the same time, better use of large aperture blur the background clutter, make the subject more prominent bird.

Footage using a telephoto lens has the characteristics of the following aspects.

Small field of view: the case of shooting the same distance with telephoto shots of the image than the standard lens. For shooting distant scenes details and not easily accessible to the subject, the scene of the shooting range is relatively small space.

View depth: to highlight your subject in a cluttered environment, the virtual background. But need to be accurate focusing when shooting, so your subject appear blurred phenomenon, which can be compared by using a tripod to buy it.

Perspective less effective: a telephoto lens will compress the distance of space depth, while the virtual background image perspective effect to weaken.JVC GR-D370EX Charger

type of coarse texture of the photo shoot techniques

Photo features and style analysis
Coarse-grained JVC GR-DVL9800KR Charger texture of the type of photos that picture the image on the screen gives a rough sense of particles, similar to the deal over the net when printing enlarged generated special effects, different from the other the pursuit of saturated, fine texture of the picture type. Because this type of photo images coarse particles, the density is not enough, so the little black and white contrast levels, the photo does not look too strong dark black, and highlights will not look too pale, the whole picture of the color and tone was flat and soft, is more elegant and rich sense of art photo types. Market reaction to and discussion of photography generally more unique and elegant character of the people, can enjoy this type of photo style, elegance who studied photography, but also more than a soft spot for this type of photo. But some ideas for the lack of photography and art, often can not accept the rough texture of the screen, will think this is caused by an amateur or professional film shooting, and even cut corners that are suspected of the photographer. Therefore, this type of photo shoot, the best quality of art to understand our customers, so self-defeating, to no avail.jvc gr-d395us charger
Focus on techniques that capture

1. Film shooting method using the High Sensitivity: This is the easiest way to obtain the image coarse particles. Those who love these pictures, you can use when shooting high-speed film, such as 800 degrees or 1600 degrees of film, using the 135mm camera to capture, zoom effect will be more apparent. Rinse photos, negatives emulsion because of its already high sensitivity of rough particles, it is natural that the film would also like to get rough than image. National Cheng Kung University, and a small photo to enlarge the film, its coarse particles would be more obvious the phenomenon (135 film benefits ... ... ... ....) 2. Developing a sense of film by using the method: the use of 400 degrees can be sensitized film to shoot, and deliberate exposure of less than about second gear, and its lack of exposure during development in part by the increase in film development in time to compensate. Film in the developer in time for longer, there will be a light-sensitive particles coarsening phenomenon, which is commonly used by developing a sense of law. Using this method, the need to remember to take pictures underexposed the exact number of files, so please print the company according to the formula of compensation back. Manufacturers due to the current release of the new film Jieyou very detailed image quality, so this method appears to increase a sense of developing an ineffective; but in the past, - it is the most commonly used photography techniques. 3. High-rate discharge: that is when the use of film and zoom features make the image coarse particles to achieve the effect of coarse-grained texture. General film blow or more than twice the magnification of the time, use a image for enlarged leaving coarse particles, and in the high magnification, the eye can clearly see it. 4. Can also use poor shots, such as schema-screen printing of the same techniques to obtain the coarse texture of the photo. Regardless of the method, the best exposure when shooting can be a little less than one file, so the photo will print out more coarse-grained sense.jvc gr-d72us charger
