The folding grey card from walimex has two surfaces, one white and one grey. The white side is used for white balance and the grey side with 18% reflection is essential for exposure measurement. This makes it the perfect tool for reproducing images with true colour and tonal value, and you can be sure that your images will not get any unwanted colour casts. The card has a practical loop for hanging on a tripod. So it is always well tidied up in the studio or on location and quickly at hand. The surface consists of a water-repellent and hard-wearing material and can be wiped off with a damp cloth. This makes the folding grey card particularly durable and a particularly cost-effective solution in the long term. With a size of 30x30cm and a weight of only approx. 58g, the grey card can be folded to the smallest pack size and fits in any photo bag. Therefore it is no longer a problem to always have your grey card with you, even on short photo tours.
