Night Vision Photography - Green Phosphor (P43) Image Intensifier [Krea 2, Qwen 2.1]

This LoRA captures the authentic analog physics, color science, and optical anomalies of traditional Green Phosphor (P43) Image Intensifier Tubes. It has been trained to apply a gritty, realistic night-vision filter over landscapes, wildlife, tactical scenarios, and even illustrative art styles.

v1.0 [Qwen 2.1] and v1.1 [Krea 2]

Trigger word: nvdstyle

Color & Spectrum Control:

• monochromatic P43 green phosphor — Locks output to pure single-wavelength green and suppresses RGB daylight color bleed.

• green phosphor illumination / phosphor glow — Sets ambient luminous quality.

High-Frequency Noise & Texture (Grain Drivers)

• microchannel plate scintillation noise — Triggers dense, authentic light-intensifier noise.

• photocathode grain / photocathode speckle — Generates fine salt-and-pepper surface texture.

• analog photomultiplier noise — Enforces analog sensor texture across deep shadows.

Optical Artifacts & Lighting Dynamics

• spherical light bloom / blooming violently — Generates realistic highlight blowouts around light sources.

• concentric halation rings / green halation halo — Creates authentic lens flaring around saturated cores.

• white-hot core saturation — Forces pure white clipping at the center of intense light sources.

• ocular back-splash — Recreates green glow reflecting onto faces/eyes from an NVD eyepiece.

• tracer arcs / vertical streak flare — Generates motion light trails and sensor blooming spikes.

Framing & Aperture Geometry

• circular ... view with dark vignetted edges — Enforces round ocular tube housing with black corner masking.

• rectangular full-frame night vision photograph — Decouples tube masking for edge-to-edge sensor framing.

v1.0 [Krea 2]

Steps on Krea2 Turbo: 6-8 (higher introduces unwanted artifacts)

Trigger Word: nvdstyle (Recommend using key prompting tokens below)

Key Prompting Tokens:

• Classic Optics: vibrant green phosphor glow, saturated lime-green monochrome tint

• Vignette Control: viewed through a distinct circular vignette framing with soft blurred edges

• High-Gain Artifacts: dense scintillation grain texture, heavy analog photomultiplier noise, spherical light blooms , heavy analog camera noise with a dense scintillation grain texture

Additional Prompting Tokens:

• Light control:

  • Overexposure: intense overexposed spherical white-green light blooms that violently wash out the frame

  • Sensor Streaking: intense vertical sensor-clipping light streaks trailing downward from the light source

  • Complete burnout: catastrophic bright daylight completely obliterates the camera sensor, creating an absolute blinding whiteout with heavy horizontal light bleeding trails that melt away fine geometries

• Material & Environmental Interactions:

  • Near-Infrared Reflectivity: [subject] is highly reflective under near-infrared amplification, emitting a bright ghostly white-green radiant glow

  • Atmospheric Starlight Amplification: a pitch-black sky populated by sharp pinprick stars gathered and amplified by the lens
