Another basis many people forget about because they "blur the background". So what am I asking ?! Anyway, it has a huge impact on the photo and if such a "photo shoot" does it on a case-by-case basis, this is how his photos will be, accidental. Nothing will give a new, beautiful body and glass for the few lowest domestic.
If the background is wrong, despite the good light, good pose and other favorable factors, the photo will still suck. Simply in the world.
Even if the background is so blurred that what is in the background can hardly be seen, you can choose its colors, brightness and clarity. These are very important factors that we have an influence on and which should be controlled.
The situation is a bit different in the case of smaller background blur. Then you need to take care of other factors such as: integrating the photographed person into place, accurate control and conscious placement of elements in the frame and good composition of the whole.
The basic mistakes of beginners are, for example, protruding branches from behind the head of the model, a mess in the background that distracts attention and trimming important elements in the frame.
Just because you do a portrait does not mean that you focus only on the right position of the model and good light. The background is equally important.
