What does a GREY card do?
What is a Grey Card? A grey card is designed to help photographers to adjust their exposure and white balance settings consistently by providing a reference point. This reference point will set a white balance, or color balance, point for a particular image set and all images captured thereafter.
Why is it called 18% GREY?
18% grey comes from the world of print,m and is based on reflection. An 18% grey card reflects back 18% of the light that hits it. And it is actually the geometric mean between white paper (95% reflective) and black ink (3.5% reflective). But capturing light is different to print.
Can you print a GREY card?
A “gray card” is 18% reflective. Even if the PS equivalent color is 127,127,127, different papers will reflect light – and more importantly color – inconsistently. Yes, you can print “gray” on a sheet of paper by following these steps. But for use as a “gray card”, it will be a waste of time.

What is a photographic grey card?
A photo of the gray card is taken and used to set white balance for a sequence of photos. For post-processing white balance, a photo of the gray card in the scene is taken, and the image processing software uses the data from the pixels in the gray card area of the photo to set the white balance point for the whole image.
What is a digital gray card?
A digital gray card is used for white balance. You use it to get custom white balance in a scene. Cameras don’t know what the colour temperature is in your scene. They base automatic white balance on an average of all the colours in your scene, not on the colour of the light falling on it.
What is a camera gray card?
Gray Card (~) A gray card is a middle gray reference board, sheet or similar material, typically used together with a reflective light meter either in camera or hand held, as a way to produce consistent image exposure and/or color in film and digital photography. You can use a ~ for WB reference instead of white.
