Book review

I read 'Ali and his CAMERA'
The book writen by Raymond Pizante.
Main character is Ali. Ali lives in Istanbul, the
largest city in Turkey. He lives on the top floor of
an old building near the famous Blue Mosque.
He have not his camera. One day, his mother asked him.
"What are you doing" Ali said,"I am taking photos of these
boats."
How can him take photos?
I had doubt.
He is taking photos in his head. He can see the photo here.
Ali points to a place just beside his eyes.
His camera is memory of him self.
I want to his remembrance, and I want to memorize an English word.
