I took this today as part of a white balance exercise and am using it to complete last week's found items challenge. It was taken in the full sunlight using a white priority balance setting. The box is white. I also tried the auto white balance setting which gave an almost identical result, a high kelvin setting of 7500 which added warmth to the image and an incandescent light setting which give a distinctly blue hue to the result. All of which is somewhat irrelevant since you are looking at an adjusted black and white version. It just so happens that the image also meets the definition of a found object with box which references nature being placed in the 90 degree angle in the branch of a tree.
