Do you shoot people's clothes with white background cloth with flash (floor flash with soft mask) or photography?

Everything is all right, but in general, lighting and focusing are always on with ordinary brightness, and flash is used for exposure, because flash has good color rendering index and high brightness. If all the photographic lights are on all the time, it is more expensive to buy a lamp with good color rendering index. If it is too bright, the model's eyes may be tired.
