Grey cards, exposure step


Grey cards, exposure step cards like the one shown and warm cards are very good tools for custom and special effects whitebalancing. However, make sure they are specifically designed for photography/videography or your results will not be accurate. Be careful what ‘white’ you use as well because there are different shades and tones of white and that will influence your whitebalance as well. Notebook or printer paper white is about as standard white as it gets though I’ve done ‘dirty WB’s’ off of T-shirts, cars, trucks, walls, etc long as they were acceptable and represented what I needed when a whitecard or other tool wasn’t available.
