I just read about WB lens caps on the net. Sounds fishy to me. Has anyone any experience with these they would be willing to share.

It's just another way of setting the white balance, it's easy to use just take a shot with the cap on and then use this image as the reference to set the "custom" white balance. I find it more accurate than Auto WB, but I don't use it all the time, just mainly at night. If you shoot raw, you can adjust the white balance in post processing in programs like DPP.

There is an alternative that defines the word "cheap" -- a white coffee filter over your lens has a good rep for setting a CWB (or using as a target in a Raw converter).

Or cut a white foam cup to fit over your lens to get yiour WB shot. (This setup can also be used to turn your camera into an incident light meter, but that is another thread...)

I use a translucent white Burger King drink cup lid. :)

The resulting image can be used for 'custom white balance'... This works out great even when you shoot RAW because the acquired white balance is applied to all the RAW files by default. You don't have to do any more white balance work when post processing your RAW files.
