You start off with 60 exposures of film that Dr. Oak gives you. Don't waste these, because you'll have to do a return trek to Dr. Oak's main lab to get a refill. Now to find the pokemon. Some are pretty rare, and some are easy to find. Some may be hiding under rocks or even in the trees. Some may even be chasing other pokemon. To get a good picture of a pokemon, its a good idea to get its attention first so you can get a head on shot. Thats what you have pester balls and apples for. Throw pester balls to get a pokemon's immediate attention for a quick shot or throw an apple to a pokemon as bait so you can get a better shot. Some pokemon won't respond to pester balls or some may not respond to apples, so you need to use your cunning to sneak up on them. This game has a lot of in depth play and also the graphics are superb, hardly many polygons at all with smooth pictures of all pokemon
