18% Grey Card for Digital Photography
This pocket-sized card provides a neutral 18% grey reference alongside white and black targets for accurate white-balance and exposure calibration. Photographers who need consistent colour rendering across changing light conditions can carry the set on the included neck strap for quick access during shoots.
Limitations of reflective calibration cards
The card relies on ambient light falling evenly across its surface, so strong gradients or mixed-colour illumination will reduce accuracy. It cannot generate its own light or compensate for spectral spikes from non-continuous sources, and the fixed 18% reflectance does not suit scenes that require a different middle-grey reference.

Questions about this item
Should I choose the white, black or grey card first for setting exposure?
Start with the 18% grey card to set a neutral exposure baseline, then use the white or black card to check highlight and shadow detail.
How does the 18% reflectance value translate when I meter the card in my camera?
Metering the 18% grey card gives a mid-tone reading that places middle grey at the centre of your histogram, so highlights and shadows fall correctly.
