@milaniet This is happening a lot this winter. I have seen this before, but not to the extent I am seeing it now. Perhaps it is because of the weather we have been having.
@la_photographic This shot is part of my January brown series. I like the brown tones of the oak leaves in the winter time. In addition, they were perfect for my brown series.
@pyrrhula Thanks. I do not know if the leaves are losing their colors or changing their colors. It almost looks like the brown pigmentation is being worn off by the winter precipitation. I will keep observing the leaves and see what happens during the next month.
