note: because this wood has some yellow tint, I have my usual difficulty in getting the color exactly right and thus you'll see some slight variations in the colors here that are not due to the aging but due to inconsitencies in the lighting and color correction. The main point of the series, however (the difference between unexposed and exposed sections) is not seriously hurt by this inconsisency.
As you can see, two weeks of exposure causes a marked darkening of the color but another month makes no additional difference.
