The lighting in the studio is generally more than a few watts. Do you still need a flash? Can I get the correct exposure with the camera's automatic metering system?

You should ask such a question because you don't know much about indoor photography. There are two kinds of lights used in the studio, one is flash light source and the other is continuous light source. The continuous light source does not need to flicker, and the lamps are selected according to the light needed, and the power is generally high. The flash light source does not specify how many watts it must have, and it needs to be determined according to the area of the studio. Of course, the lighting for shooting advertisements is generally not less than 800 W/s, and the automatic metering system of the camera can't get the correct exposure, so an exposure meter is needed.
