Here is a link to Calumet grey cards.

I’ve never used a grey card, so maybe you could suggest something (inexpensive would help).

Or if you have other suggestion I’m open. I did find some sites on the web that had the warm and cool white balance cards.

They’re expensive, but another couple days of this… I’ll be toast.(burned out) LOL
