Source for plastic "18%" Gray Card

General Color & Graphics Digital Camera / Scanner Color
1

I am looking for something made of plastic - or otherwise durable and permanent.

Many of the modern cards are optically neutral, and are good for white balance - but I am looking for something which is, in addition, a standard gray value, suitable for determining exposure: with light meters, film, etc.

I am already aware of the controversy surrounding 18% versus 12%, etc.

Thanks !

Hi Ken,

I’m not sure if this is what you’re looking for, but it’s probably worth a look:

It’s a material called Spectralon, made by Labsphere. It comes in different shades, so they might have an 18% gray.

I know this is an old thread, but still a relevant question. If anyone else is currently looking for something similar, you should check out <http://store.rmimaging.com/digitalgraycard-100.aspx>
