A very effective printing aid for assessing your colour filtration, paper grade, or exposure. Saves time, paper, and frustration, and makes sure that you are improving your print with each alteration that you make

• You expose your starting image in the centre segment, then using the same part of the negative, expose six different filtration, grade or exposure comparisons around this - You have now produced a Ring-a-Round
• Easy comparsion and basis for adjustment
• Accepts 10" x 8" (25x20cm) paper
