Because we don't need walking time to/from the location, and the lights and everything are all set up exactly how we need them when you arrive. Studio sessions are generally about 10 to 15 minutes. Outdoor sessions are about 15 to 20 minutes (we will walk to and from the meeting point together). That said, I'm not a hard stickler for the exact number of minutes; more important is that we get a photo that you love! If we can do this in a few minutes less time, I consider it a win! If we need a few extra minutes, that's ok too!
