What the AI looks for in Photographic Light Meter Grey Cards
- Reflectance
- 18% reflectance grey, ideally with a white or black reverse side. Photographic metering conventions are built around the middle-grey standard.
- Spectral neutrality
- Choose a card sold as spectrally neutral for white balance, not just a grey-looking card. A card with a colour tint skews custom white balance.
- Matte surface
- Non-glossy finish, angled to avoid glare. Specular reflections throw off both the meter and white balance.
- Condition
- Replace a card that is faded, stained or creased. Ageing and dirt change the card's tone and its neutrality.
Brands that matter
- Kodak: The classic flat grey card reference.
- Lastolite: Collapsible EzyBalance grey and white targets.
- Calibrite: The ColorChecker targets, formerly sold under X-Rite.
- Datacolor: The SpyderCheckr colour and grey targets.
What to avoid
- Glossy or laminated grey cards that glare
- Cards with no stated neutrality used for colour-critical white balance
Questions
Is my meter calibrated to 18% grey?
Not exactly. Meter calibration sits somewhat below 18%, which is why grey card instructions often suggest adjusting slightly. Bracket your first shots and check the histogram.
