The package says "Gray Scale & Value Finder". This common tool is a VALUE FINDER for painting or other art projects or situations where you have to determine the gray values of colors or shading. In other words, a visual helper. These are usually numbered one to ten, as this one is, and are printed as halftones. (You can see a halftone screen in the gray sections under a paragon loupe.) Perfect for painters and illustrators, good price, sturdy enough for its purpose, and even has a protective sleeve. Very happy customer here.
However, someone mentioned that it should be eleven divisions, and that refers to a GRAY SCALE for scanning. Proper gray scales are continuous tone (CT) like on a developed photograph, and are divided into 11 steps for 10%, 20%, 30% grays, etc., up to 100% for black, PLUS white. There are also 21 step versions that include 5% increments plus one for white. Gray scales are scanned with artwork to help with tonal and color corrections. Printed gray scales (halftone) are available, often as book companions, but are not appropriate for digital image correction, and should only be used in a pinch and only with the proper eyedropper adjustments. I hope this clears up any confusion for prospective buyers.
