Shooting price of photographic shoes

It's best to shoot shoes with flash light source, but I don't know if you have some basic photography skills. Generally, if nothing can be done, there is something wrong with the flash light source. Aperture and speed are different from natural continuous light sources. You should pay great attention to this. If you buy a flash light source, it is recommended to buy U2' s 200W portable flash, or a gold cup. They all have this suit, and the price is around Sanduang District 1700. The photos taken by the flash should have higher resolution and clearer details. You should also have a flash device, otherwise you can't synchronize the flash ~ Your camera has an organic top flash, but it is not recommended because the top flash is direct light. If you use it to flash the picture, there will only be direct light, which has a great influence on the picture. What does the last question mean? I don't understand. What's beyond ~ I hope to ask again and answer ~
