Why is the camera set to M mode when shooting in the studio?

Because in the studio shooting, the flash is instantaneous high voltage, and other gear modes only measure the light generated by instantaneous high voltage and automatically expose it, which will lead to overexposure or inaccurate exposure. But the studio also has a constant light source. At this time, you can shoot even if there is no M file.

Moreover, according to the flash index of the flash, the speed of M-block cannot exceed some specific values. Otherwise, it will cause local black screen.

M file is fully manual, which can shoot satisfactory or special effects films according to the photographer's requirements, and is very suitable for photographers who are familiar with metering, aperture and shutter.

Advantages: The metering, aperture, shutter and ISO can be adjusted manually, and the exposure combination can be adjusted arbitrarily for a single parameter to achieve the desired effect of the photographer.

Disadvantages: more complicated.

Extended data:

When shooting scenery, the screen is mostly sky, which may lead to overexposure. In the M range, the aperture can be reduced by one or two steps, such as 1/250 sec F7. 1 (the larger the value, the smaller the aperture) or1150secf5.6 or 1/200 sec f7.

When shooting a person, you will find that the light behind is very strong, which makes the person's face very black. In addition to filling the light with a flash, you can also slow down the speed or increase the aperture value within the range of m, such as1125s F5.6 or1/200s F4.0, which will increase the exposure and ensure the normal exposure of people at this time.

However, the background may be overexposed, but at this time the characters are the main body. If the contrast is too large, you can choose other ways, such as not under the backlight, using reflectors, flashlights and other means.
