Take a Look Inside Brooklyn Beckham's Photography Book, 'What I See'

"My mom cried," Brooklyn told ET, revealing Victoria's proud mama moment over his new book. "Like, the last day I was getting everything finished, like the paper material and all that. So, yeah, my mom cried. She's really proud."

"My dad bought me my first camera when I was 15," Brooklyn told ET, "a Pentax K1000."

Brooklyn told ET mom Victoria encouraged him to give photography a try. "My mom was like, 'Do it. If you don't like it, you can [switch].'"

Brooklyn said that, between his famous parents, mom Victoria is the one who likes having her picture taken.

What I See also includes plenty of shots of Brooklyn's younger siblings, brothers Romeo and Cruz and sister Harper.

And Cruz seems all too happy to model for his big bro.

Brooklyn's famous father has lots of tattoos in honor of his family.

"I'm actually moving to New York in August to study photography for four years," Brooklyn told ET. "I'm really excited. Photography is [it], that's what I really want to do."
