B&W PHOTOGRAPHY /High Key

I will make a reservation right away that it can be difficult for a beginner photographer to do work in the "high key" technique. Although the general recommendations seem to be simple: take a picture of a light object on a light one, for example.

But with a "high key", it's not so simple. There are several rules, observing which, a novice photographer can cope with the task.
There are only five main ones:
-Use white / or light / background when shooting.
-Shooting subjects to choose in white tones / or light /.
-The shadows should not be deep, in the idea - light and transparent.
-The area of ​​the shadows is as minimal as possible.
-The main light should be volumetric and soft (large).
