I chose to convert to black & white to put focus on the fine structure and pattern in this section of the tree trunk.
For the B&W version I used preset 3.06 Structured Silver from Silver Shadows 2.0. For both photographs I used a preset from Julian Kost - Darken HP -20A 70F - to add a vignette.
The next phase is to see this on print. A monitor and a piece of art paper are really two different types of output medias and I think the best way to judge and appreciate a photo, is when it has been printed in the correct way on a piece of high class art paper.
Please visit my gallery if you want to purchase those photos on fine art paper.
