People often ask me why I don’t shoot my black and white shots. The answer I usually give is that color is such a powerful element in photos both emotionally and symbolically, that it seems a shame to leave it out. Another reason might have something to do with this color acuity test.
The lower your score the better, with zero being perfect. I scored a 3. Which makes me believe that I have a particualrly high sensitivity to color, that in turn influences the way I create my photos.
