To access a photograph's EXIF data an alternative method is the normal PHP Exif function. <?php $exif_data = exif_read_data($pic1); $edate = $exif_data['DateTime']; ?> See: http://php.net/manual/en/book.exif.php

ImageMagick only supports setting a very small number of EXIF properties. See http://www.imagemagick.org/discourse-server/viewtopic.php?t=14234
