E26 Value Finder 6 3/8" X 7 5/8" This is a very useful tool for every artist. The red film gets rid of any color and you only see values. Usually if there is a problem on a painting, it is almost always value. This size is great for studio and plein aire.  It allows you to see your painting and your resource material at the same time so that you can effectively judge your values. Value strip is included. Very useful to set boxes up by value.
