Cinematic Astronaut Adrift Over a Planet
FluxCinematic Astronaut Adrift Over a Planet is a Flux.1 dev prompt for a 16:9 film still. A lone astronaut in a white EVA suit above a curved planet with an off-frame sun lens flare, a teal atmosphere rim-light, a gold visor reflection, a drifting tether and a deep black starfield negative space produces a cinematic space-film still with no text.

Prompt
A cinematic film still, a lone astronaut in a white EVA suit adrift in deep space above a curved planet horizon, the sun just off-frame to the right producing a long horizontal lens flare cutting across the visor, the planet's atmosphere glowing in a thin teal rim-light, deep black starfield filling most of the frame as negative space, the suit's gold visor reflecting the planet below, slow tumble suggested by a trailing tether drifting behind, 65mm lens, shallow depth of field on the astronaut, cool teal-and-black grade with one warm rim, no text, no letters, no watermark

How to use this prompt
"The sun just off-frame to the right producing a long horizontal lens flare" is the motivated-light technique — placing the source off-frame and naming its flare tells Flux to grade one side of the suit as warm rim while the rest stays cool; an on-frame sun would flatten the lighting. "Deep black starfield filling most of the frame as negative space" is the composition cue that makes the astronaut read as isolated — without the named negative space Flux fills the background with nebulae and the loneliness vanishes. "Gold visor reflecting the planet" anchors the astronaut's position; without a reflection the visor reads as a blank helmet. The drifting tether sells the slow tumble without motion blur.
Variations to try
- Swap the planet for a gas giant with banded amber clouds for a 2001-style space-odyssey still
- Change the angle to the astronaut reaching toward a distant spacecraft for a rescue-beat variant
