The function of reflective umbrella (who knows photography)

Reflective umbrella is a special reflective tool with different colors.

The silver umbrella does not change the color temperature of the flash; The golden umbrella can appropriately reduce the color temperature of the flash; The blue umbrella surface can appropriately improve the color temperature of the flash. In flash photography, the most commonly used reflective umbrellas are mostly white or silver.

When in use, put the umbrella on a tripod with changeable angles. When the umbrella is illuminated by strong light, the scattered light is soft and the shadow is light, so it is an ideal light source. When taking close-ups of portraits, it is not stimulated by strong light, which is most suitable for taking portraits and still lives.

Extended data

Adjust the setting exposure.

The process by which light reaches the surface of a film and makes it sensitive. It should be noted that by exposure, we mean film exposure, which is a necessary process for us to obtain photos. Often depends on the combination of aperture and shutter, so there is the word exposure combination. For example, the shutter measured by the exposure meter is 1/30 seconds, and the aperture should be 5.6, so F5.6 and 1/30 seconds are an exposure combination.

Exposure compensation (exposure compensation)

Generally, exposure compensation is used in automatic or semi-automatic exposure mode. If it is a full manual exposure mode, exposure compensation is rarely used, because the amount of light entering can be changed by adjusting the shutter and aperture.

In the Gao Fancha environment with complex light and strong contrast, it is sometimes difficult to give consideration to the overall situation and achieve the expected results by using automatic exposure or shutter and aperture priority mode. At this point, the photographer needs to manually adjust the corresponding exposure parameters of the equipment, which is called exposure compensation, also known as EV. For beginners, exposure compensation is generally used for still life and scene shooting.

This situation is suitable for calmly adjusting parameters and taking photos of different compensation schemes for selection. However, in the contrast picture, it is difficult to give full consideration to exposure compensation, and it is easy to lose sight of one thing and lose sight of another.
