Does anyone know the photography major?

I suggest you buy a spotlight. You can buy a good one in the second-hand market. Using energy-saving light bulbs and desk lamps is a joke. There is a big difference between light efficiency and professional lamps. Civil lamps can only be used for lighting. They have no requirements for light intensity, comparison value, reflection, light absorption and luminescence, and professional ones are different. In addition to the above requirements for light, the most important thing is to balance light, which can make invisible light. It doesn't cost much to buy a second-hand spotlight, and it costs less than one or two hundred yuan to touch it. I hope I can help you!
