Ken Colburn writing for the East Valley Tribune describes EXIF data in layman’s terms and explains what kind of information may be held about photos. In particular, the question of whether EXIF data can be used to determine where a photo was taken is discussed:
“In the case of photographic images, the EXIF data can contain any or all of the following:
– Date and time the picture was taken and any subsequent edits
– Camera settings such as make, model, ISO speed, aperture, shutter speed, focus length, whether flash was used.
– Any software that was used to edit or touch up the photo
– General description of size, resolution and copyright info
– Longitude and latitude (but only on cameras that have a GPS included, such as smartphones and some specialized digital cameras)
The list of potential data that can be mined from photographs is actually too long for this column, but some recent stories have created some fear of this extra information. EXIF data is not some evil plot to undermine mankind, it was created over a decade ago as a way for really valuable information about a photograph to be captured” [Read More]
