I am in a rural town and want to open a photo studio. What photographic equipment do I need?

See what kind of quality requirements your customers have. If it is normal, it is enough to get a Nikon D90 plus Longteng 17-50 F2.8, three lamps, two 300 watts, one 200 watts, several background curtains, a background bracket, a high-power electric fan, various props, clothes, accessories, hats and so on. If you don't buy a printer, you can go to specialty store to print, which is expensive and the quality can't be guaranteed.
