The document is a self-portrait. 
The photo was taken in 1956 by Vivian Maier. 
I think the scene takes place in her living-room. 

There is the artist in the middle. She is sitting on a chair. 
She is looking at the spectators when the camera is taking a picture itself (it's automatic). 
The picture is very dark. So we can't see her eyes. 

I don't really like the picture because I prefer photos in colours. But it's interesting. 
It gives you emotions. 
I guess the woman is scary and mysterious. She is probably very unfriendly. 
She looks determined. I believe she is a warrior in life.
