On the problem of shooting light of carding machine

Flash is a must, ordinary card machine does not necessarily have a hot boot-that is, the thing that installs the flash, and there is still a question mark about whether the airborne flash can flash successfully, so it is not recommended.

The ever-burning lamp I bought on Taobao. The light bulb is a three-color energy-saving lamp, and its brightness is naturally worse than that of the flash, so its life may not be very long. Then the color rendering is estimated to be around 80% (that is to say, the color may not be as bright as the real thing), but it is much cheaper than the flash system and should be competent for opening an ordinary online shop.
