The "Dog Day Afternoon" photo contest invites participants to submit digital photos of domesticated dogs, with specific rules for entry. Photos must be resized to a maximum of 650 x 490 pixels, and only one submission per member is allowed. Editing is limited to brightness and contrast adjustments, while all submissions must be original work. The contest will culminate in a voting poll for members to select their favorite photo. Participants share their experiences and photos, discussing techniques and the personalities of their dogs, fostering a sense of community and enthusiasm for the contest theme. The thread emphasizes the joy and challenges of capturing the essence of dogs through photography.
