white balance

[Fotografer]

i know that you cant beat a grey card but how about one of these <a href="http://photojojo.com/store/awesomeness/white-balance-lens-cap/" target="_blank">white balance lens cap</a>. it's a lens cap that you can use to help you set your white balance for where you are. i want to know if anyone has used/played with one? i was thinking it would be easy to use this since it would serve a dual purpose.</p>

<p>and i'm gonna leave these two other links here just because i think they are really neat-o and maybe something you would like for Christmas/Hanukah/other religious holiday/etc. <img src="http://thephotoforum.com/forum/images/smilies/icon_biggrin.gif" border="0" alt="" title="biggrin" smilieid="106" class="inlineimg" /></p>
