You can get a "Digital" greycard, specificly for DSLR's, I have one, works really well. IIRC I got it for free on a camera mag cover here in the UK, lighter in colour to the Kodak grey cards which I also own for film use

Grey cards aren't always neutral. The Kodak ones in particular are somewhat warm. 2. Your meter is calibrated for approximately 12.5% grey (ISO standard). Cards are calibrated to 18% grey (Kodak's choice at Ansel Adams suggestion). Thus grey cards do not actually function as described but rather cause a slight overexposure . -Adam On Tue, Jun 8, 2010 at 11:35 AM, eckinator <[email protected]> wrote: > I prefer a grey card.
