This cedar tree is 400 years old. Taken with a normal 17-40 lens (photo 1) it doesn't seem to have much going for it but with the 15mm fish-eye it seems to look more attractive, I haven't figured out why yet. I just tried the circular cap to see what that would look like, I should stepped back a bit more so the whole circle showed,I need to watch that next time.
I don't know what type of tree the dead one is or why it died but the birds enjoyed sitting in it early morning time, seemingly to warm up. .
