Prompt
Xenobiological field survey photograph, frame extracted from 4:3 documentary footage, handheld Hasselblad X2D 100C body with XCD 45mm f/3.5 lens, RAW+JPEG dual capture, auto white balance locked to 5100K, exposure: f/5.6, 1/320s, ISO 200, no flash, no diffuser, no polarising filter.
LIGHT SOURCE — Viridis-7 orbits a K2V orange dwarf star. Ambient sunlight therefore 15–20% dimmer than Earth noon, colour temperature approximately 4800K, directionality: sun at 35° elevation angle to camera left, casting long warm amber-orange hard shadows. This makes shadows cool-blue by contrast — every shadow on rock or root has visible blue-violet undertone. Sky colour: pale sage-yellow at zenith transitioning to warm haze at horizon — NOT blue. This is physically accurate for K-type stellar illumination through a dense biosphere atmosphere.
FOREGROUND GROUND LEVEL — cracked laterite-analogue substrate, deep ochre-red clay colour visible between surface root mats. Dominant root architecture: massive buttress root systems 4–6 metres tall, surface texture like compressed black bark with embedded symbiotic lichen crusts in muted grey-green. Ground covered in fallen leaf matter: not brown — pale grey-silver, decomposed, matted flat. Scattered water puddles in root hollows reflect sky colour accurately.
MIDGROUND ORGANISM SCALE — tree-analogues 60–90 metres tall, trunks 2–3 metres diameter, canopy opaque and flat-topped. Bark surface: deeply fissured, almost black with oxidation, occasional pale mineral streaks. No flowers visible. Hanging root structures descend 10–15 metres from lower canopy branches. Between trunks: dense understory of fern-analogues, 1–2 metres high, fronds dark olive, drooping, slightly wilted in midday heat.
ATMOSPHERE VISIBLE — distant tree trunks fade into atmospheric haze with biologically correct scattering: haze is slightly green-yellow, not blue. No fog. Humidity visible as slight gloss on all leaf surfaces. No mist.
SKY GLIMPSE through canopy gaps — pale sage yellow, overcast diffuse, no visible clouds from ground, single small moon visible as faint white disc in gap.
PHOTOGRAPHIC IMPERFECTIONS that prove realism: slight chromatic aberration at high-contrast leaf edges, shallow depth of field with roots at f/5.6 sharpness falling off at 8m distance, faint rolling shutter micro-distortion in top 5% of frame from handheld movement, no colour banding, natural sensor noise at ISO 200 visible in shadow regions as fine luminance grain.
NEGATIVE PROMPTS: no bioluminescence, no glowing plants, no neon colours, no fantasy lighting, no render artifacts, no perfect symmetry, no artistic composition, no HDR, no oversaturated greens, no blue sky, no Earth-like vegetation colours, no cinematic grade, no depth-of-field blur on foreground subject. --ar 3:4 --style raw --stylize 0 --chaos 0
