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.
How is this News for Nerds? It is common knowledge.
That means I can actually use some sort of extra data, let's call it "meta" data from now on, to manage my photos! Imagine if in the future they could store extensive details like even the temperature of the sensor! I know I am making things up now, but perhaps it would be convenient for example on some sort of futuristic long exposure technique where you would need dark calibration frames.
Can't wait for tomorrows news for nerds, where Mandy George-Shelley after twenty years takes another look at the mouse and discovers a second button which can do so many things, but can be a privacy concern if you right-click the wrong things...
