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.
