Which is better for a SLR camera to take a macro in the sunshine or in the light of the studio?

Single-lens reflex camera uses sunlight to shoot macro, and uses the light in the studio to shoot macro, each with its own characteristics. As long as it is well controlled, there is no big difference in effect. It should be noted that the macro shooting distance is very close. Whether shooting with sunlight or light in the studio, we should pay attention to avoid the shadow of the camera and photographer from affecting the shooting.
