This image was taken from one of my favorite places to visit in the Sawtooth Mountains - the top lake below the base of Mount Heyburn. This waterfall comes from the outlet quite close to the lake.

On a technical note about creating this image, it was a labor of love requiring much patience and vision. The image is actually derived from two 6X7 slides taken at different exposures. For the foreground in shadow, the proper exposure was 8 seconds to properly expose detail and give the waterfall that silky look. However, at 8 seconds, Mount Heyburm and the sky were significantly overexposed, requiring me to take a second exposure at a dramatically faster shutter speed ... and on this exposure the waterfall and stone in shadow was too dark to show detail. Where the labor of love comes in, is in the process of combining both digital scans of the two slides into a single image. This required creating a mask that hides the unwanted parts of the two images, and was so fine in detail that it took me the better part of two days! Every pine needle on every tree in the transition area had to be manually brushed in or out.
