The light of the basic concept of the application of luminosity description

Light is photography CANON PowerShot S410 Charger indispensable element, no light there is no video, photography loses its meaning. During the filming process, clever use of light, can take out satisfactory photograph.

Luminosity is light source luminous intensity and the light in the surface, intensity of illumination and object surface of the CANON PowerShot SD110 Charger floorboard of the present height. There are many factors that affect the luminosity, such as light source type, light source nature, luminous intensity, irradiation distance and subjects of surface reflected light rays ability and so on. In addition to other than natural light, and the rest of all kinds of light can be artificially controlled the luminosity. For example, the closer the light source is produced by the greater the luminosity of the radiation, more far then is small.

In addition, the CANON PowerShot SD200 Charger luminosity and exposure time and the existing relationships between the depth of field. When luminosity is bigger, the exposure time needed for short, when photometric more hours, the exposure time long. Photometric great, the need to use small aperture and shutter speed, in order to make accurate picture exposure, therefore depth of field is deeper, when photometric more hours, the need to use large aperture and shutter speed, in order to improve the brightness of the screen, make accurate exposure, and therefore more shallow depth of field.

The intensity of the light and is inversely proportional to the distance, this method suitable for sunshine outside of the common except the CANON PowerShot SD300 Charger light source. For example, the distance light source in 1 m the brightness of the set to 1, it is two meters brightness into 1/4, three metres is 1/9.

Main body and the environment of the relationship between light and shade photography skills

Picture want to express canon lp-e10 charger main body, be sure to highlight the main content and weaken the background, the background as the assistant play correctly. Will express clearly cannot be subject only by these, we know that in any screen, comparative and intense picture will be more attractive, so inevitable, if the picture of the main environment light and shade relations hold of, can very good outstanding subject content photography skills.

If the lack of environment can compare object, so we can try to multiple perspectives composition, for example, in a scenery canon eos rebel t3 charger scenery as flat, using light plane clap out the photograph is can work on details, but also because of the lack of light changes, the photos will lack of charm. So, you can transform Angle, such as, or natural light direction changes, such as morning, dusk, when light is rapidly changing, you made out of the picture also can have very good effect of light and shade, want to express the main body of the content, because the light and rich and colorful.

Obviously use the contrast of light and Canon EOS Kiss X50 Charger shade highlight the main content, weakening the surrounding environment, in addition, figure in a blue and yellow light color contrast.

Consider to have comparative and Canon EOS 1100D Charger intense main body and the environment, and in the exposure, must pay attention not to specular highlights or shadow department for metering, this film will not, clap out photos not underexposed is excessive exposure, must be in the grey area between film, for many times value.

Digital camera photography GanGuangDu Settings

GanGuangDu called ISO value,CANON PowerShot S410 Charger is a measure of the degree of light sensitive film parameters, digital camera in the definition of the same film and ISO, representing the CCD or CMOS photographic of components of the photographic degree, the more that the numerical ISO as sensitive material the photosensitive stronger ability. In the digital camera inside, through the adjustment of the size of the GanGuangDu, can change the brightness of the photo. So GanGuangDu also became indirectly control the luminosity of the numerical picture.

ISO values can control the exposure,canon powershot sd630 charger usually adds a ISO values, aperture is a narrow, or improve a shutter, and vice versa. Generally, the shooting sports or objects in the insufficient light produced, GanGuangDu Settings should be high some, because GanGuangDu high, and a shutter speed can be increased at the same time, the stability of the picture. But high GanGuangDu will make photographs pixels increased, reduce the clarity of the picture. Instead, GanGuangDu is lower, the screen pixels is less, the quality more exquisite, but this situation is not suitable for shooting sports objects and AnGuang environment photography.

ISO formulas for the S = 0.8 / H canon powershot s40 charger(S GanGuangDu, H for the exposure), for GanGuangDu are still not familiar with the standard of the people can refer to set up ISO values, in the sunny day or cloudy under the condition of light outdoor, the use of 100 or 200 ISO GanGuangDu; In the cloudy or rainy outside, use between 200 and 400 ISO GanGuangDu, under natural conditions in the indoor or the evening the light, use 400 or 800 ISO GanGuangDu.

Avoid large aperture picture dark corner

The lens of the central canon nb-1lh charger image quality best, namely, the highest resolution color saturation highest, from the lens center to edge, the image quality is gradually declined, lens edge imaging quality more bad, namely of clarity, saturation, brightness is low. When using large aperture, the difference will be bigger, may appear obvious dark corner. When the background picture for light color, dark corner more apparent.

The photographer can use digital camera CANON PowerShot S410 Charger with the largest aperture shortest focal length with white walls, shooting to detect dark Angle lens. If found in no use filter, no correct installation filter mask under the prerequisite of the photographs appears dark corner, the corner can be determined because aperture setting is too large, the small aperture can appropriate weakened dark corner.

Dark Angle of produce may also and filter, filter in the purchase should be carefully detection. Install a good canon powershot sd630 charger filter lens aperture used after the biggest with the shortest focal length with white walls, shooting if still found a dark corner, likely is too thick, filter by digital camera short JiaoDuan took, replace the thin filter can weaken dark corner phenomenon.

Footage of dark Angle may also is a lens manufacturing problems, is difficult to put an end to the camera, but high quality lens photography picture dark corner will be shallow.canon powershot s40 charger
