When you reach rainbow cloud, Mew is the only Pokemon there. At first it is in a pink bubble that goes back and forth in front of you, but you can't take a picture of when it is in the bubble or the picture will come up as ???. To get Mew out of the pink bubble you must hit the bubble with apples or pesterballs, Mew will disappear then reappear in the pink bubble two more times so just hit it again. Then Mew will come at you in yellow bubbles and all you have to do is hit the bubble again, this time Mew will come out of the bubble and head for a bubble in front of you. This is a nice picture to get. BUT... To get an even better and closer picture you must throw pesterballs at Mew and hit Mew (apples don't work very well for they will bounce off of Mew blocking that perfect picture). Mew will spin then slowing move toward you, facing you. But if it isn't close enouph just hit it with another pesterball. Warning if Mew gets to close to you it will disappear but if you only hit Mew with one pesterball it will disappear as well, but Mew will come back just by hitting the yellow bubble with Mew in it again. If you are quick you can get Mew spinning which oak likes and is nice on it's own, but just remember Mew alone is a special shot altogether, so most likely Mew will be your best piture.
Hope that helps you great players out there.
