The film taken by the studio flash is slightly dim and the color is not bright.

Hello, I'm a senior photographer. If your film is a bit dull, it may be that your lens is gray. You can see whether the lens should be scrubbed or blown, or you can set incorrect exposure. You can use the shutter and iso aperture correctly. If the film is white, the color temperature can be increased. If it is still not bright enough, you can make it a little saturated. Third, you can determine the direction of the light. However, indoor shooting should follow the standard, and the exterior can be adjusted according to the style of the shooting scene, with neutrality, portrait and scenery, which can be adjusted according to your own preferences. I hope this helps.
