A, loading and unloading lens method

SLR camera lenses and the connection between the fuselage is through a bayonet socket to realize that what of, is generally three knife or within the three knife type, in order to prevent a screen shot from its fuselage fall off, have locked card projection. Different manufacturers camera different, locking devices position and a slightly different operation method, the loading and unloading differences between the lens, such as the mount nikon F within three knife is, counterclockwise rotation installation, and the Canon EF bayonet socket is three knife in clockwise installation, and lens when insertion anchor point the initial position also is distinguishing.

Why to using the bayonet socket. The first can replace the camera lens with the connection is the way the snail mouth, like screw twist into nut (such as the scope of influence of the huge M42 snail mouth), with the passage of time, the snail mouth become not adapt to the new user needs, such as snail mouth unable to realize basic fully open aperture film, the demand of shooting contraction aperture, and this is monitoring the fundamental function of SLR cameras, then, bayonet socket is made.

Installation of the lens to the careful operation, in the process of remove the lens more carefully, to pull out when the lens must be vertical, otherwise not only not easy to pull out, also easy to damage a cylindrical tube or the bayonet socket. When rotating lens hand should hold the lens of a cylindrical tube parts, unfavorable hold the aperture ring or the JiaoHuan, zoom ring. Outfit lens camera should be the red dot on the fuselage and align the red dot on the inserted after, according to the requirements of the rotation direction exactly, and hear the lock of "snickering" sound so far.

Sand and dust in the larger of the environment, as far as possible don't replace lens, lest dust into the reflector box, both may touch the CCD, may also lead to wear parts of the activity has even fault. If it is to be in the bad environment change in lens, then the fuselage, turn it over to the bayonet socket below loading and unloading can of utmost avoid dust entering, the change of the camera down as soon as possible and shall cover cover put such as bags or lens in the cylinder.

Second, USES the good GanGuangDu ISO

ISO, commonly known as the GanGuangDu, in the traditional camera use film packaging can clear see ISO values, such as ISO 100, ISO 200, ISO 400, and so on. By adjusting the ISO values, can make the digital camera light sensitivity change. In the same conditions, the exposure must), ISO, the higher the faster the photographic, exposure of time required to shorter. That is to say, in the same environment, the same shutter aperture shooting case, if the higher ISO setting value, then the digital photos taken from the brightness.

Adjust ISO

The choose and buy a digital camera, now will start shooting. Want to want to take out the exquisite digital pictures, then we have the need according to the scene, the choice of shooting model, also need to pay attention to the size of the GanGuangDu, white balance option, control throw the background of the composition, the direction of the light frame, and the lateral, the choice of light. Next we'll see how the photo was taken.

1. The high GanGuangDu role

Now that the improvement of ISO can effectively reduce the CCD photographic time, then this is for us in the filming of weak light provided convenience. Because usually weak light or night in filming will need a long exposure time. Once the exposure time is too long, a shaking of the hand is easily taken effect of clarity, the only way is to use a tripod to fixed camera. But after all for most users, always carry a tripod out entertainment is not a easy thing. Another is sometimes some of the incident happens at night and to get lighter to take the result, the most direct way is using high ISO values, so that to take the result will be better. High ISO values apply to include the scene at night, low light environment and fast paparazzi, etc.

2. Low GanGuangDu role

But not GanGuangDu as the more the better, because although ISO values pictures of the weak small brightness, but its quality is exquisite degrees is the best. High ISO and photos of the particles are the most obvious, pixels more. So high ISO setting does not apply to demand higher quality of digital pictures, especially like shooting, still life and like shooting close-up.

Three, the choice of appropriate exposure mode

Exposure mode turntable

Exposure is photography a common nouns, is in the process of filming the amount of natural light into the camera. If the amount of light is too big, so it is very bright photos, called excessive exposure; If the amount of light is too small, so it is very dark photos, known as inadequate exposure. Grasp the strength of the exposure, for the picture of the good or bad has a very important role. Exposure mode and divided into:

1. Automatic exposure

Automatic exposure is digital camera according to light conditions, automatic analysis and choose a kind of exposure strength exposure mode, namely people had said fool-operation. This way is not any technical, all depend on a digital camera to be automatic identification. According to shoot the light of the specific conditions of the automatic Settings by use of aperture and shutter speed. When light is insufficient, the camera will be playing in on flash. In some news reports and emergency in order to fight against time, typically use the automatic exposure.

2. The shutter is preferred

Shutter priority is defined in the manual shutter speed by film camera automatic acquisition aperture value. In the shooting sports objects we often find shooting out of the subject is fuzzy, this is because most of the shutter speed fast enough. In this case you can use a shutter priority mode, probably determine a shutter value, and then to shoot. When the shutter speed less than 1/60 SEC suggest using a tripod to shoot, in order to avoid because hand jitter and influence photos clarity. The faster shutter, into the amount of light in the less. The slower shutter, the greater the amount into the light. Shutter priority for more on the object shooting sports, especially in sports is the most commonly used in the shooting. The shutter can be used in the state of the moment frozen objects, and slow shutter can realize the throw the moving object.

3. Aperture priority

Aperture priority is taken by photographer, the first choose the aperture of the need, then according to the site by the camera, determine the light the shutter speed. The greater the aperture, into the greater the amount of light, the effect of the more obvious background falsified, was the subject of filming the more important; The smaller aperture, into the smaller amount of light, the focus of the before and after of the depth of field(www.chargerbatteryshop.co.uk).
