What are the requirements for digital camera sales?

What you said upstairs is wrong. Without professional knowledge, it is difficult to sell. For example, what should you say if someone asks you what lens to use? Is it ccd imaging or cmos imaging, you know? And pixels. . And so on a series of questions, others buy, some have a certain understanding, if you are wrong, others will not believe you and will not buy the products you introduced, so you can have a general understanding first, and learn the details while selling, because many brochures have detailed introductions.

If you are interested in this aspect and know enough about it, you can become a photographer. There is no time and place restriction, and it is a cool profession, hehe.
