The footballer is said to have purchased a top-of-the-range camera and is taking lessons to improve his skills.
"Since David took some photography lessons, he never puts his camera down. He's bought himself how-to books and spends hours trying to perfect shots," a source told the Daily Star.
"He thinks he's David Bailey now he's had a few lessons. He takes pictures of everything - birds in his back garden, flowers, the sky, his kids playing football.
"He's spent thousands. His camera equipment is better than some professionals'."
Wife Victoria Beckham was recently reported to be planning David's post-football career, suggesting that he enter the fashion industry.
