I'm getting ready to head up to Lake Superior to do a video shoot for Shuttermonkeys, so stay tuned, soon we'll have an exciting new adventure bringing you behind the scenes as I do all sorts of crazy stuff to make compelling photos. This is one of the spots I'll be visiting, a little "sea cave" along the shore of Lake Superior in northern Michigan. I used an ultra-wide lens to capture this dizzying array of sandstone striations. Because of perspective distortion, the part of the lines closer to me look larger than the more distant parts, so although the lines are all parallel, they appear to diminish in size and converge in the distance, creating a radial pattern of diagonal lines. This creates an effect known in art as a "vanishing point," and it is a very effective way to draw the viewer deeper into the composition. I used focus stacking to ensure sharp focus throughout the image frame - these and other techniques are discussed in great detail in my upcoming Ultimate Landscape Photography Course . Canon 5DSR, Canon 11=24mm f/4 lens, ISO 100, f/11, 0.5 seconds, focus stack.
