Extract data from a photo

October3

All pictures taken with digital cameras add information to images they take. A lot of information. To see it, install imagemagick using this command on the command line..

sudo apt-get install imagemagick

Then, just use the identify command thus..

identify -verbose /home/me/pics/some_picture.jpg

and it should pump out a heap of data.

Personally, if ever uploading photos to the internet (never) or emailing them to friends (rarely), I make sure to strip all the data from them. For this, use mogrify, also from the imagemagick suite…

mogrify -strip /home/me/pics/some_picture.jpg

Now the exif data has been removed. Nice!

 

True dat..
