Camera: What light was used to take this shoe? Is it warm? What is the wattage? Where did it run out?

It was not hit by any light. Technically, it was taken alive. The color temperature is warm, around 4500. It depends on the adjustment of the scene, and has nothing to do with the wattage of the lamp.

Half of the blur is due to the large aperture, which is about 1.4 or 1.8. However, the depth of field of the large light pattern becomes smaller, and the same effect can be achieved with a long focal length.
