The first step in our process is to figure out what is around you for shops. The easy way is to open a phone book and look up travel or go online and type in AAA.com
Next the most common place to find a photo store is to look for AAA ravel store. Most major cities have them to help make it more convenient for people. You DO NOT need to be a AAA member to use their passport photo store.
If you do not have a AAA store near you, then look for the nearest post office in the phone book or online and call them first. You have about a 50% chance of this working although I find passport photos at the post office don't always show your good side like a private shop taking them.
Lastly,if both those don't work check in with your local drugstore. Many times they have a camera to take a passport photo for you.
