Including Custom Posts in Archives

I was all excited to create a handful of custom post types for my personal website, but then I realized none of my new posts were showing up in the monthly archives or the rss feed. This is the code I used to register the post type.

add_action( 'init', 'create_my_post_types' );
function create_my_post_types() {

register_post_type( 'photography',

array(
'labels' => array(
'name' => __( 'Photos' ),
'singular_name' => __( 'Artist' ),
'add_new' => __( 'Add Photo' ),
'add_new_item' => __( 'Add Photo' ),
'edit' => __( 'Edit Photo' ),
'edit_item' => __( 'Edit Photo' ),
'new_item' => __( 'New Photo' ),
'view' => __( 'View Photo' ),
'view_item' => __( 'View Photo' ),
'search_items' => __( 'Search Photos' ),
'not_found' => __( 'Nothing Found' ),
'not_found_in_trash' => __( 'None in Trash' ),
'parent' => __( 'Parent Photo' ),
'query_var' => true,
),
'rewrite' => array('slug' => 'photography', 'with_front' => false),
'supports' => array(
'title',
'editor',
),

'public' => true,
'show_ui' => true,
'menu_icon' => '',
'publicly_queryable' => true,
'exclude_from_search' => false,
'menu_position' => 4,
)
);
}
