"They call me Mellow Yellow (Quite rightly)" - Donovan, 1966. Not however being mad about, as in Donovan's case, Saffron but rather the trees from my Autumn woodland walkabout.
Beeches and oaks in yellows and golds in mellow Autumn sunshine; the beauty of the season.
Everything glows in the low angled sunlight.
It's all about illumination...
... and contrast.
... oh and chestnuts that abound in plentiful bounty.
