The camera of choice for most people has evolved significantly with the increasing adoption rate of smartphones. People are capturing daily moments at ever increasing rates with the camera they are most likely to have with them. Almost all smartphones have the ability to write location data into the metadata of the digital photo. This feature is usually on by default, or you may be asked the first time you use the camera app if you'd like to enable this feature. Saying yes turns it on permanently.

I question if that's what you really want to do. Location data is a fantastic feature when you're on vacation or traveling away from home. Apple's iPhoto and Aperture programs have a really fun mapping feature to show you where all your photos were taken. It's fun to see the pins appear on the map. While that's great in these limited cases, I think it's not useful when you're around the city you live in or at home.

If you always have location services turned on in the camera app, every photo you take at home is embedded with that information. The photos of your cute kids playing in the back yard pool is leaving a trail for others to potentially follow. With the rate at which we're all sharing photographs thru texting, email and social services, it's certainly something to keep in mind.

I've changed the location services setting on my iOS devices to off by default so the random daily shots I take lack this information. I don't need it there. If I change my mind later, I can always add it in via my photo program. I now make a conscious choice to turn location services on when I'm someplace where the photo location adds value.

On a device running iOS 6, this camera setting is located in Settings > Privacy > Location Services.
