P.K.
Search photographers in Your area and then go to websites. Look at their work Unless you have a particular area outside that you like, ask for their suggestions. I would do communion pictures separate. Then if you want a family picture, I would go very casual. Jeans and white shirts for all. Formal pictures are so hard to get and does not show personalities. Casual ones are the best no worrying if a dress is wrinkled etc. just my opinion. I think if you look on websites you will see what I mean.
