Depending on how many pictures you take of the activity, how much memorabilia you have and how big it is, you might want to choose a different size album than you usually work with. One of the things I like best about this type of activity is that it is seasonal. Let's consider some things you might want to include in such an activity album. These photographs provide a summary of the activity for the year or season. Many activities sponsor formal photographs for the participants.
Dance studios do it, but so do city sports leagues.
While you're at it, snap a few pictures of your child having his or her formal photograph made. If not, you can take your own at an event. Just get the whole team together for a pose. Don't forget to take your camera to at least one practice. It's nice to include a few photos of your child engaged in a favorite activity while not wearing the official uniform.
