How to keep the lights off when shooting indoors?

I have taken two weddings and used D80. Warm color depends on personal taste, and some customers will like this color very much. If your camera can adjust the color temperature and white balance, try 6000K K K. If not, you can choose incandescent white balance.

If these functions are not available, you can only adjust the white balance later.

An old photographer told me that if you can use a flash, you don't need it. Try to use a high ISO (fortunately, you can use D80ISO800) and a monopod (tripods are useless, because the people you shoot are moving, otherwise the shutter will be empty).

If you must use a flash, use a professional such as SB800. The light source should rush to the ceiling above the front, not to the subject. The flash illuminates the environment, not the subject. If the subject is photographed, it is plane light, which is ugly.

And try not to use M file, because it is too late to take a snapshot. When not flashing, use the shutter first to ensure the safety of the shutter and the photos will not be empty. If a flash is used, the aperture gives priority to ensuring the depth of field.
