Sandra Sacki is the winner of this week's SunShots theme, "Stripes," for the image of a moving walkway in Washington DC shot with a Nikon D5100, 55mm lens at f4, 1/60 sec. and ISO 1100. Baltimore Sun photographer Algerina Perna critiques, "Sacki spotted stripes formed by lights and metal strips in the ceiling and walls. The silver and white tunnel leads the eye into a splurge of color. The illuminated ceiling adds a 3D-quality and sparkle to the stripes. Sack employed the rule of thirds by off-setting the focal point to the right."
