Let's start with the conclusion. Personally, to do copywriting, you must understand PS, and even regard PS skills as the basic skills of copywriting. The reason is simple:
1 period-learn PS, and you can express your creativity completely and concretely.
The impact of images must be stronger than that of words. Our brain can quickly process the information received by vision, but it needs more twists and turns for words. As a graphic processing software, the position of PS needs no elaboration.
Copywriting is also a creative job. Sometimes, subtle words may not show their subtleties without pictures. Secondly, pictures and words usually complement each other. After learning PS, you can come up with a complete set of "graphic combination scheme" in your mind, not just words. Expressing your creativity completely and concretely can make you progress faster.
Second, it is convenient to communicate with designers.
Even if you only know some basic functions, it is better than not, because it is convenient for you to communicate with designers better. At worst, master more technical terms and let designers know that what you said is a good choice. I once talked with the designer for a long time to make the background of a color block gradient, but I just can't describe what this color block gradient is.
Sometimes, in order to make cooperation easier, we may just infiltrate the knowledge of other fields a little, but it is very beneficial to teamwork, saving time and effort, and also helping ourselves to grow.
No.3-It's always right to learn one more skill, right?
PS has almost become the standard for people in the workplace now. Maybe it's not a PS, but a simple image processing software like Meitu Xiu Xiu, because you can't tell when any task will come to you quietly. Moreover, copywriting often deals with pictures and videos, and it is not a bad thing to teach yourself this craft.
