Artichokes are good to eat. They are a real treat. You peel the leaves to the “meat” inside, in a spiral motion that echoes the visual path in this great, big edible flower as shown from above.
The artichoke is shown here photographed straight down on a velvet background with some side lighting to bring out the spiral pattern. I bracketed exposures, and started layering using hand-HDR with the darkest exposure. The resulting low-key layer stack approaches life from the opposite direction than my more typical high-key layer stack. Poppy Dancer is another example of this technique, with some explanatory and tutorial links at the end of the Poppy Dancer story.
