Thanks everyone for the suggestions. I have tried the "HDRI" technique before. Once when I was in Yosemite, I was taking pictures of the Cathedral Rocks and the sun was starting to set, casting beautiful red tones across the cliff faces. The foreground was very dark but there was a nice reflection in the water. I was shooting both film and digital. I set up my tripod and bracketed several shots with exposures for the rocks and sky, then shot several more for the foreground and water. I combined the images later and it worked like a charm.
So thanks for the reminder W. Smith, I will try the 'HDRI' technique next time I shoot trees. I will try the other suggestions too.

P.S. Just for the record, technically what is being discussed is not 'HDRI' (High Dynamic Range Imaging) but 'IDR' (Increased Dynamic Range) also called 'DRI', 'Expanded Dynamic Range', or 'Digital Blending.'
'HDRI' is much more than taking two or three pictures and putting them together. 'HDRI' requires multiple exposures to pick up details in all the different shadows, mid-tones and highlights and then combining them into a 32bit image using special methods. An image is produced that is quite different from traditional photography.
