A heads up – all digital cameras, including those on smartphones, store something called EXIF data in the photo.
99% of the time this is harmless and often useful – especially if you have an interest in creative photography. it stores lots of things like shutter/aperture, ISO setting, what lens/focal length you used, whether flash was used (the exact features depend on your camera).
You can look at it with free software downloadable online as standalone packages or a browser package.
But beware if you have a modern smartphone with a GPS reciever! Now this is often a useful thing as well, as you get maps when you are travelling – but the camera software often also stores the location of your photo in the EXIF data. Beware also, that some newer “travel” compact cameras and DSLRs have this receiver built in.
There are times when you don’t want this to happen – so either
- switch off geotagging
- remove the exif data with software
- or use a camera without GPS receiver….
Otherwise you are handing over info to those who might oppose what you are doing – not just feds but (as the software to read the data is so easily available) anyone else who could grass you up if they disagree with your actions..
