What Your Photos Know About You (itworld.com)

itwbennett writes: Sandra Henry-Stocker became curious about how much more complex the jpg format had become since she first did a deep dive into it more than twenty years ago, so she dug into how much information is stored and where. "This information is quite extensive — depending on the digital camera you're using," says Henry-Stocker, "containing detailed information about the photo such as the make and model of the digital camera that was used, whether a flash was used, the focal length, light value, and the shutter speed that was used when it was taken. And, if your phone/camera has geotagging turned on, it will also include the altitude, longitude and latitude of the place where the photo was taken." Henry-Stocker used exiftool to extract and label the data so you can see what is collected, and how you can protect your privacy as well as your intellectual property.

Thanks, we know.

No kidding. The EXIF data intentionally contains all that information! And it's really useful to a photographer!
