I started to play MGS HD collection and i started MG2. I'm not at the part after i defeated Olga and are at bottom of the ship to take pics of Metal Gear, when does the character change to Raiden? Do you really have to play as him through most of the game?

It changes after you get the pictures.
If you enter the Konami code before loading your save, you get to play as Snake for the rest of the game.
