Dude on "Shutter speed in EXIF" http://www.kriesi.at/support/topic/shutter-speed-in-exif#post-36329 Mon, 02 Jan 2012 07:52:27 +0000 Dude 36329@http://www.kriesi.at/support/ Hey, basically you'd need to convert it back (i.e. see <a href="http://www.enliteart.com/blog/2008/08/30/quick-shutter-speed-fix-for-wordpress-exif/" rel="nofollow">http://www.enliteart.com/blog/2008/08/30/quick-shutter-speed-fix-for-wordpress-exif/</a> ) because wp automatically changes the speed to decimal values. You can find the code in flashlight\includes\helper-slideshow.php - search for following function: <pre><code>function avia_exif_data($attachment_id = "")</code></pre> It requires some fiddling with the php code. berrald on "Shutter speed in EXIF" http://www.kriesi.at/support/topic/shutter-speed-in-exif#post-36296 Sun, 01 Jan 2012 23:34:55 +0000 berrald 36296@http://www.kriesi.at/support/ Hello, Excellent theme, as usual… Is there a way to display the shutter speed as a fraction (1/125 s and not 0,008 s) when the speed is below 1 second? Hope you will understand my poor english… Happy new year from France!
