Excuse me, how is the light distribution of this portrait photography? Red, blue light and shadows on the background and body.

At first glance, you can know the effect of printing with the corresponding color projection lamp.

The picture above uses a blue curtain and white light. Then there is a spotlight on the left and right sides of the camera, the red cover glows red on the model, and another white flash above the model flashes down synchronously (the shadow on the model's neck can prove it). The camera uses a higher shutter, which should be no less than 800 seconds. Before shooting, the photographer has an assistant who scatters shredded paper bubbles and the like above the model. In this way, this effect is formed.

In the photo below, the model is leaning against a solid white wall, with a projector lamp with a red cover on the left and right sides of the camera. The camera uses a large aperture and low speed shutter to shoot, and uses a tripod.
