How to restore the photographic lamp to the factory?

Hehe, I also use Canon 50D+ Canon 24-70 zoom lens. I think the color is very good, delicate and natural. This should have little to do with the setting of the machine. I adjusted the standard. I used to shoot children, and the color temperature was set at 5600. The flash index in the shed is generally one quarter or one half, and the aperture is opened to 2.8. Sometimes the aperture is open to F4, so I bought another Kengo. UV mirrors do have some effects.
