How to light up the interior of the car to shoot the car mat? This car cannot be modified.

First of all, it is not that easy to fill the light in the car. The activity space is so big that some people even say that the bigger the aperture, the better. What does it mean to flash an external flash with hot boots? I don't know what these people are answering. Simply mention the fill light, just open all four doors and turn on the lights, and then find a good position. But shooting by yourself is time-consuming and laborious. I really don't recommend shooting it myself. Just find a photography company. I recommend you to find Shanghai Jiangpin Vision. I hope the landlord will not be misled by people who don't understand.
