You would be correct! You do!
Saying a photo booth is an “open air” photobooth is like saying you live in an “open air” house - meaning you probably live outside! If I put a bed, TV, kitchen table, etc in my yard, I could call it an "open air" house but would want to live out there? Probably not.
You have taste right? You seek authentic and cool experiences and you want a REAL, classic, “get inside and pull the curtain” photobooth and that is getting harder to find these days.
Why, because so many new fly-by-night operators have jumped into the "photobooth rental" game with this idea of an “open air” photobooth because it’s cheap (a DJ can add it to their services) and in reality it’s just a camera on a stick (usually inside a little white metal box on stand with maybe touch screen and you and yours stand in front of a gold curtain and get your pictures taken). Now while this might be a fun thing to do, it is still NOT the real classic photobooth experience, which is what you want right?
With a real photobooth you get inside the booth (this is probably why it is called a booth), you close the curtain and you are in your own private little photography studio getting your pictures taken. Your inhibitions let loose and your inner model comes out when you are not posing in front of everyone in the room and you’ll always get better pictures in a real photobooth!
So if you are planning an event and want a real photobooth experience then rent a real photobooth! You and your guests will be happy that you did. It will be noted that you went for the cool, retro, real deal photooboth versus some cheap pop up thing on a stick.
Here’s to keeping real photobooths going for years to come!
