Helios folding gray card 30 x 30 cm with scale

It functions as a gray table (white on one side and gray on the other) to compare and It serves as a gray 18% card (flipped with a white background for white balance) for color and exposure balance for cameras and for proper exposure settings, especially for monochrome and glossy subjects. Before shooting, take a picture with the lighting on your model already fixed with the grey card. When loading the first photo for processing on the computer, calibrate the gray value to the card you took. This will result in identical and bright colors. You can use the grey card as a comparison scale thanks to the metric and inch scale. Ideal for using photo documentation in labs, for online auctions to get an accurate idea of the size of the auction item or product photography in general. The grey card can be washed and folded in no time. The grey card is a patented Helios product that will find a place in every photographer's pocket.
