What was wired in
Works
The lamps come on and the sky goes dark, and the jogger and the pigeons keep to their original paths. At 1152×640 this needed strength 1.5.
A realistic nighttime version of the same park: the fountain, bench, lamp post and trees in the same positions and the jogger following the same path, the lamp post lit with a warm glow, cool moonlight on the gravel and the fountain water catching the light, deep natural shadows under the trees. Only the lighting changes from day to night; identical composition, framing, camera movement and motion.
daytime, bright sunlight, blue sky, overexposed, worst quality, inconsistent motion, blurry, jittery, distorted
