- Don't stress about trying to complete the missions that pop up. Those are mostly to give you hints on how to set up unusual Pokemon behaviors. Actually trying to complete them all will make you very mad. And if you do really want to complete them all, use a guide. Some of them are very obtuse and not easily figured out by just playing.
- It's not as fun as selecting them yourself but if you are shooting for the highest score then don't be afraid to use the auto-picker during the results screen. It seems to pick the highest score automatically which is helpful when you have a bunch of very similar photos.
- Also, don't be ashamed to use a guide to get all the different star photos. There are more than a few that are very specific.
