Taobao products are photographed on a white background and turned red and black. How to solve it? Is it white balance or flash?

This color difference is a common problem of almost all cameras, and it is extremely troublesome to adjust it by lighting and white balance. If you want to have a good effect, you must learn some post-processing technology, which is not only inexpensive, but also casual, and you can have any effect you want. I did a little work on the above picture to see if it was much better. The relatively simple post-processing software is Light and Shadow Magician and Meitu Xiu Xiu, and the advanced software is PS. This picture was processed by a light and shadow magician. First, use the light and shadow magician to open the picture, click the automatic white balance, and then click the reverse effect in the top effect to make the background white and the whole picture brighter and more beautiful.
