When the camera's fill light effect is not good, you can use soft light as the main light source, so there will be no shadow and you can shoot a pure white background.

If you need to shoot a pure white background, you can take pictures with a good camera, and you can shoot a pure white background by adjusting the aperture and sensitivity.

1, the best aperture value of the lens

Each lens has its best aperture value. Generally speaking, the maximum aperture value is reduced by 1 to 2 levels, usually in the range of f/4 to f/8, to balance the influence of aberration and diffraction phenomena and obtain the clearest image.

2. Change the settings as quickly as possible.

In order to change the settings, many cameras now provide various methods, such as changing metering, focusing mode, white balance and so on. Please find out how to change it and try how to do it as quickly as possible, because you never know when you can take pictures quickly and change the settings quickly.

3. Do you need exposure compensation?

Camera settings may always be inaccurate if the camera continues to be underexposed or overexposed.

Step 4 set the flash

Try not to use the built-in flash, but you still need to know how to set it, such as normal, red eye prevention, front curtain synchronization and flash intensity, so it is still useful when you have to use it in the dark.
