Macro detail in a blink

Extreme macro photograph of a tiny mechanical garden on a watchmaker's bench: brass gears blooming open like flowers, clockwork petals of polished copper and enamel, springs curling like vines, a single ruby jewel as a dewdrop, warm workshop light, razor-thin depth of field, creamy bokeh of tools in the background. No people.
Ultra-wide scenes at 21:9

Show the promptHide the prompt
Ultra-wide cinematic digital painting of a colossal whale made of shimmering green and violet aurora light, gliding slowly through a sea of clouds high above a futuristic city of slender glowing glass towers at night. Stars overhead, soft rays of light trailing from the whale's fins, deep indigo sky, epic scale, serene and majestic.
Tall compositions at 9:21

Show the promptHide the prompt
A very tall fantasy illustration of a vertical stack of floating islands, each one in a different season: cherry blossoms in spring at the top, golden wheat in summer, red maple forest in autumn, and a snowy pine island at the bottom. Rope bridges connect the islands and waterfalls spill from one to the next into soft clouds. Painterly, rich colors, warm light, whimsical and detailed. No people.
Clean product shots

Minimalist studio product photograph of matte black over-ear wireless headphones resting on a stack of soft pastel peach cylindrical pedestals, against a seamless warm peach background. Soft diffused light from the upper left, a gentle long shadow, subtle reflections on the matte surface, clean premium advertising style, sharp focus. No text, no logos, no people.
Playful concepts in one shot

Studio photograph of a large clear glass light bulb standing upright on a dark wooden desk, with a lush miniature rainforest growing inside it: tiny ferns, mossy rocks, a thin waterfall pouring down the inside of the glass and a soft glowing mist where the filament would be. Warm directional light, glass reflections, shallow depth of field, dark moody background. No people.
