Sam on "htaccess old adress -> new WP"

Hello,
We have recently migrated a ASP.NET site to WordPress. And we have got some url's that we want to not end up in the "oops, cant find the page" - page. :)

The old is like this:
http://example.com/camera/id/123/default.aspx

The new on WP is:
http://example.com/camera/

I don't need a general way to do it, because 95 % of the URL's are new and the site is restructured. So it's just this url and maybe 2 more I'm intrested in.

Please advice me how to bend the .htaccess file, that comes with the standard WP installation.
