One more thing, you should consider whether you want the flash to trigger or the constant light. I use constant light instead of trigger to shoot still life. Constant light is generally 1 set of 3 exhibitions, and 500 yuan -800 yuan trigger type 1000 yuan, which can be measured by yourself. Constant light is suitable for shooting small objects and beginners. Triggers, suitable for larger scenes (2 square), need to consider parameters.
I wish you an early success!
