That’s a nice shot. Did you take it?

Yep. In San Francisco of a crow that I’m convinced has been following me.

At 10:53 on July 22nd in fact. The great thing about mobile phones is you’ve always got a camera.
You should check out the rooftops around your home. I’ve had crows waiting for me when I got home. It’s most unnerving.

Very cool! I never knew these images had meta-data stored inside them. How do you access it?

I know how to access metadata in Windows, but you’re a Linux person, are you not? Perhaps there is something similar.
In Windows, right click on the file and choose ‘Properties’. Select the ‘Summary’ table and then click the ‘Advanced’ button.
On your pic, this also tells us that your phone is a HTC Desire, that it was set to an ISO of 119, and that its focal length was 5mm.
This is EXIF data stored in digital photos by a camera. If Linux doesn’t support its display, try googling ‘EXIF viewer’ and see if one of the items listed there works in Linux.

Correction, select the ‘Summary’ TAB, of course!

I had no idea so much was snuck in there! Thanks.

As a Windows user (move away from the keyboard please) I use Xnview which is also available on *nix.
It’s always worth checking metadata in documents fetched from the Internet. Especially FOI documents redacted by someone who had change tracking turned on.
