<title>View detailed information about a picture</title>
|
|
|
|
<p>Pictures taken by digital cameras are stored with a host of extra
|
|
information embedded in them, such as the date that they were taken, what
|
|
exposure settings were used on the camera and, in some cases, even where the
|
|
picture was taken.</p>
|
|
|
|
<p>This topic shows you how to access this information.</p>
|
|
|
|
<section id="date">
|
|
<title>Show the date in the status bar</title>
|
|
<p>You can display the date that a picture was taken in the status bar at
|
|

<p>The detailed information stored with digital photos is called <em>Exif
|
|
data</em>. You can view it by installing a plugin for the image viewer.</p>

<p>Some cameras are able to attach <em>geolocation</em> information
|
|
(geotags) to digital photos. Geotags are usually just the GPS coordinates
|
|
(latitude and longitude) for the place where a photo was taken.</p>

<p>The map will show the location that a picture was taken in only if there

is geolocation information attached to the photo. Many cameras do not attach
|
|
geolocation information to pictures.</p>
