Get EXIF shutter speed as fraction

    Hello!

    I extract the metadata from an attachment with the wp_get_attachment_metadata function. This also includes the shutter speed, which is automatically converted to a float by WordPress. So I get values like this: 0,016666666666667. How can I convert this back into a fraction?

    Thank You,
    Elektrowolf

    Solved it!
    I changed line 289 of wp-admin/includes/image.php to
    $meta['shutter_speed'] = $exif['ExposureTime'];

    I use code similar to this in my themes instead:

    $imagemeta = wp_get_attachment_metadata();
...
	// shutter speed handler
	if ((1 / $imagemeta['image_meta']['shutter_speed']) > 1) {
	echo "1/";
		if (number_format((1 / $imagemeta['image_meta']['shutter_speed']), 1) ==  number_format((1 / $imagemeta['image_meta']['shutter_speed']), 0)) {
			echo number_format((1 / $imagemeta['image_meta']['shutter_speed']), 0, '.', '') . ' sec';
		} else {
			echo number_format((1 / $imagemeta['image_meta']['shutter_speed']), 1, '.', '') . ' sec';
		}
	} else {
		echo $imagemeta['image_meta']['shutter_speed'].' sec';
	}
