Post-Processing

Overview

Apply 28 GPU-accelerated visual effects to your 360° renders. Effects run as "hooks" at different stages of the rendering pipeline, giving you full creative control over the final look of your images.

Post-processing is available to all license holders (Standard and Pro).

How It Works

Effects are organized as a chain — they execute in order, each receiving the output of the previous effect. You can: - Drag to reorder effects in the chain - Solo an effect to preview it in isolation - Mute effects to temporarily disable them - Copy/paste effect configurations between renders

Pipeline Stages

Effects can run at 4 different stages: - PRE_RENDER — Before any AI processing (modify the input) - PRE_TILE — Before each tile is processed (per-tile adjustments) - POST_TILE — After each tile is processed (per-tile cleanup) - POST_RENDER — After final stitching (global adjustments)

Most effects run at POST_RENDER (applied to the final stitched panorama).

Color & Tone (5 effects)

ACES Tonemap

Industry-standard Academy Color Encoding System tonemapping. Maps HDR values to display range with filmic response curve. Controls: exposure, highlight compression, shadow lift.

Color LUT

Apply professional color lookup tables (3D LUTs) for instant color grading. Import .cube LUT files or use built-in presets. Supports standard 33-point and 65-point 3D LUT formats.

Channel Mixer

Per-channel color adjustment. Independently control red, green, and blue channel contributions. Create cross-processed looks, custom color shifts, or targeted channel corrections.

HSL Adjustment

Hue, Saturation, and Lightness control. Adjust overall or per-color-range. Fine-tune specific color ranges without affecting others.

Split Toning

Apply different color tints to shadows and highlights independently. Classic film technique for mood and atmosphere. Controls: shadow hue/saturation, highlight hue/saturation, balance point.

Detail & Enhancement (6 effects)

Unsharp Mask

Professional sharpening via unsharp masking. Controls: amount, radius, threshold. Essential for ensuring crisp detail in large panoramic images.

Detail Enhance

Amplify texture and micro-detail. More aggressive than unsharp mask — reveals hidden texture information. Controls: strength, scale, threshold.

Edge Preserve

Selective sharpening that enhances edges while preserving smooth areas. Prevents the noise amplification that standard sharpening causes.

Kuwahara Filter

Oil-painting effect using the Kuwahara filter algorithm. Produces painterly, impressionistic results while preserving edges. Controls: kernel size, sharpness. Beautiful for artistic panoramas.

Frequency Separation

Separates luminance detail from color information. Process texture and color independently — professional retouching technique adapted for panoramic images.

Real-ESRGAN Detail

AI-powered detail enhancement using the Real-ESRGAN neural network. Enhances textures and recovers detail without traditional sharpening artifacts. GPU-accelerated, runs as a post-processing hook.

Denoise & Restoration (4 effects)

Bilateral Denoise

Edge-preserving denoising that smooths noise while keeping sharp edges intact. Controls: spatial sigma, range sigma. Great for cleaning up noisy diffusion output.

Denoise + Regrain

Two-step process: denoise the image, then add controlled film grain back. Produces clean images with organic texture instead of digital smoothness.

Guided Filter

Structure-preserving smoothing based on a guidance image. Maintains edges and structure while smoothing textures. Professional-grade noise reduction.

Procedural Noise

Add controlled noise patterns for texture. Useful for breaking up banding artifacts, adding organic texture to smooth gradients, or creating specific visual effects.

Film & Aesthetic (5 effects)

Film Grain

Simulate classic film stock grain. Controls: grain amount, grain size, color vs. luminance grain ratio. Multiple film stock presets available.

Chromatic Grain

Combined chromatic aberration and film grain for authentic analog looks. Each color channel gets independent grain, producing the color fringing typical of real film.

Chromatic Aberration

Light dispersion effect — color channels shift slightly, creating rainbow fringing at high-contrast edges. Controls: shift amount, direction (radial/lateral).

Halation

Film halation (light bloom around bright areas). Simulates how film emulsion scatters light, creating warm glows around highlights. Controls: threshold, radius, color tint.

Bloom

Glowing highlights effect. Bright areas of the image emit soft light that bleeds into surrounding areas. Controls: threshold, intensity, radius, color temperature.

Advanced Processing (4 effects)

CLAHE

Contrast-Limited Adaptive Histogram Equalization. Enhances local contrast throughout the image. Excellent for bringing out detail in both shadows and highlights simultaneously. Controls: clip limit, tile size.

Stylization

Cartoon and posterization effects. Reduce the image to flat color regions with emphasized edges. Controls: edge strength, color quantization levels, smoothing.

Reaction-Diffusion

Generate Turing patterns (spots, stripes, labyrinths) as an overlay. The same algorithm as the Seed Canvas generator, applied as a post-processing texture effect.

Sensor Noise

Simulate realistic digital camera sensor noise. More sophisticated than simple Gaussian noise — models photon shot noise, read noise, and fixed pattern noise for photographic authenticity.

Dithering & Quantization (4 effects)

Blue Noise Dither

Perceptually optimized dithering using blue noise distribution. Reduces banding in smooth gradients while remaining visually imperceptible. Better than random dithering for photographic images.

Turing Dither

Advanced dithering based on reaction-diffusion patterns. Creates organic, flowing dither patterns instead of mechanical dot patterns.

Turing Texture

Texture synthesis using Turing reaction-diffusion. Creates organic surface textures (spots, stripes, coral-like patterns) overlaid on the image.

Noise Toolkit

Comprehensive noise generation toolbox. Multiple noise types (Gaussian, uniform, salt-and-pepper, Poisson) with per-channel control and masking options.

Tips

• Start with subtle settings — post-processing is cumulative
• Use Solo mode to preview one effect in isolation
• ACES Tonemap + Film Grain is a classic cinematic combination
• Unsharp Mask after diffusion helps compensate for softness
• Color LUT is the fastest way to achieve a specific mood
• CLAHE is invaluable for images with extreme dynamic range
• The Post Process passthrough processor lets you apply effects without any AI diffusion — useful for enhancing existing images
