add_action('manage_media_custom_column', 'posts_custom_columns_attachment_exif', 1, 2);
function posts_columns_attachment_exif($defaults){
    $defaults['wps_post_attachments_exif'] = __('EXIF');
    return $defaults;
}
function posts_custom_columns_attachment_exif($column_name, $id){
        if($column_name === 'wps_post_attachments_exif'){
           $meta = wp_get_attachment_metadata($id);
           if($meta[image_meta][camera] != ''){
           echo "CR:  ".$meta[image_meta][credit]."<hr />";
