Generate a wide-angle 4K cinematic shot of a rusted signboard with the phrase 'This is no man's land' written on it. A chameleon crawls across the board while an owl perches ominously on top. The scene is set in a dark, post-apocalyptic landscape with a disturbing tone, featuring a barren ground and ominous, cloudy skies. Use a Hasselblad X1D, ISO 400 for low-light conditions, f/4 for balanced depth, and a 1/80s shutter speed to capture the eerie stillness and unsettling mood of the environment."
