At the PhotoPlus Expo on Wednesday, Sony Electronics introduced two new digital photo frames to its S-Frame range, including the 8-inch DPF-D80 and the company's first 10-inch frame, the DPF-D100. Both sport 800x600 LCD screens and are the first Sony frames with a 4:3 aspect ratio. Compared to a 16:9 ratio, photos appear larger thanks in part to the elimination of borders.
