Typically, I convert an image into black and white using one of Lightroom’s presets or B&W profiles as a starting place. In this case, I used the local adjustment tool and desaturated the whole image, then switched to erase mode and removed the desaturation from the foliage on the riverbank. The desaturation technique is pretty much a blunt instrument approach: it doesn’t provide the fine tonal adjustments that are available using other techniques. However, this image didn’t require a lot of fine adjustment.
This the the Dosewallips River at the point where the road was washed out several years ago. There is a trail bypassing the washout that runs above through the woods… however, when the river is low the trail along the bank is quicker and doesn’t involve climbing up a hundred feet or so.
