Studio at first I add him to my favorite because he has go 100% portfolio then I found out that beside to his wonderful photos he has got many tips for all that who wants to learn photography that means for me too.

He have got over 14000 photos in his portfolio and I every month he upload some new ones, of curse his sales are also big but that is not a point.
