I like to photograph children, it is very interesting to watch them. They always show their true emotions, they have not yet learned to hide them behind masks. But it is very difficult. Even though I'm not 30 (don't think that I consider you old, it's a joke)). But I'm enough for 20 minutes at most. And the next day I feel pain in my back, legs, hands, and sometimes my head). But it charges and is worth it
