Something about these palm trees turned into Black & White reminds me of Southern California in the old photos from the 40's and 50's. It seems to me that not all nature shots look great in B&W but the texture of these tree photos taken in November and December of 2005 in Mexico, give the contrast needed.
This next one, in particular, has the old time look. Notice the moon still keeping watch? Gotta get me a book on B&W so I can make that moon pop out, if possible. Or maybe just download my Photoshop program.
Wishing you all a colourful week.
(These photos were altered into B&W, sharpness was added and one level of 'boost' on my Mac computer.)
