Vintage 1970's Kodak Q-13 Color Separation Guides, 7 inch. Includes Color control patches, Gray scale and Register marks.
These can fade over time if left out but this has bee in its sleeve and in the dark for a long time. This was my means of color and exposure control as a student and working photographer in the 1970's. Tape marks on the gray scale (not on the patches) but otherwise in great condition. Zero your work in with a great vintage pice of Kodak technology. Ships via USPS Ground Advantage.
