Which file does Canon eos6D use to shoot floats at night? What is the sensitivity? Do you have any shooting skills? thank you

This is not necessarily true, it needs to be chosen according to the actual situation.

If the float is stationary or moving slowly, consider using Av file, manually set a larger aperture to ensure exposure, and decide whether to reduce one or two apertures according to the imaging situation of the lens, but the mutual sensitivity can be set relatively low to improve the image quality.

If the float moves quickly, you can use TV files to ensure sufficient shutter speed for shooting. If the shutter speed is fast, in order to ensure sufficient exposure, it is necessary to improve the sensitivity, and then drive the continuous shooting to improve the chance of capturing. If the technology is good, you can also consider shooting in focus mode.

Finally, if you shoot floats at night, it is recommended to use sunlight for white balance, so as to reflect the actual color of the floats.
