The discussion revolves around a photo contest themed "Turning Over A New Leaf," where participants must submit original photographs featuring real leaves. Contest rules specify that photos must be resized to 650 x 490 pixels, and editing is limited to cropping and watermarking. Each member can submit only one photo, and once submitted, it cannot be changed unless withdrawn. The contest encourages creativity while adhering to the theme, leading to various interpretations of what constitutes a "leaf." Participants share their entries and discuss the challenges of finding suitable subjects, especially during winter months. Some members express their admiration for others' photos, while others contemplate unique ideas, such as using collard greens or skeletal leaves. The conversation also touches on the technical aspects of photography, including lighting and composition, with members sharing tips and experiences related to their submissions. Overall, the thread highlights a community engaged in both artistic expression and friendly competition.
