The rewrite module debug log is as ugly as it is itself.
Here I see that
1) $script_name get "photos" capture, and it probaly equal to "/photos".
2) $path_info if "/1".

And PHP sends 404.
Probably it tries to work with

fastcgi_param  PATH_TRANSLATED    $document_root$fastcgi_script_name;

or

fastcgi_param  REQUEST_URI        $request_uri;

Try to delete them and use

fastcgi_param  SCRIPT_FILENAME  $document_root$script_name;
fastcgi_param  PATH_INFO        $path_info;

only.
