Burls on any tree can be fascinating to photograph. They are, however, a form of stress which can be caused by an injury, virus or fungus. As well as being great photographic subjects, burls are often also highly priced by sculptors, furniture makers and artists.
The sunlight filtering through the trees did make for challenging exposure conditions but I am pleased with the overall result. The lighting lends to the beautiful textures found on this tree.
This image was another one we used the copper toner on in conjunction with the sepia to simulate an overall woodsy tone.
I took this with the Mamiya 645 Pro TL, 80 mm Mamiya 1:2.8 Sekor Lens, Ilford HP5 @ 200 developed in D76. Timing and technical details can be found on my Flickr site. http://www.flickr.com/photos/jcsilverspring1/8481119111/in/photostream
