I modified this first image to soften portions of the foliage without sacrificing some of the sharper lines that the birch were creating.
I thought the effect was interesting, but the overall image somehow projects the feel of a movie set that is supposed to be outdoors but it is obvious to our modern eye that the set is indoors and the background is nothing more than a photograph.
Here's a second shot that I converted to a black & white.
Finally, here are two additional nearly identical shots.
In the first shot I darkened the background a bit more to accentuate the white bark of the birch trunks. In the second shot I decided to reveal more the tangle of minor branches in the lower portion of the image. In both of these shots I softened the background while keeping the birch branches relatively sharp.
For the record, these were all shot at an aperture of f/4 and an ISO of 500. I underexposed the photos 1 f-stop, resulting in a shutter speed of 1/160 second.
