Auto Enhance: One-Click Photo Improvement
PixelKit's 🪄 Auto Enhance button analyses your image and simultaneously optimises seven parameters. For most photos, this produces a result in under a second that would take 5–10 minutes of manual adjustment in Lightroom.
Auto enhance works best for: photos that look flat or dull, underexposed shots taken in dim light, images with a colour cast (too warm, too cool, too green), photos with low contrast that look "washed out", and smartphone photos that didn't benefit from HDR processing.
Auto enhance works less well for: already well-exposed professional photos where it may over-process, images where you want to preserve a specific deliberate mood, and black-and-white photos (it treats them as colour images).
How the Auto Enhance Algorithm Works
PixelKit's auto enhancement analyses your image's histogram — a mathematical map of how brightness values are distributed across all pixels. From this it determines:
- Average luminance: Is the image underexposed or overexposed? How much brightness adjustment is needed?
- Contrast range: How compressed is the tonal range between shadows and highlights?
- Colour channel balance: Is one colour channel (red, green or blue) dominant, creating a cast?
- Highlight clipping: Are the brightest areas blown out to pure white? Can highlight recovery restore lost detail?
All processing runs locally in your browser via JavaScript and the Canvas API. Your photos are never uploaded to any server.
Manual Adjustment Sliders: Complete Reference
| Slider | Range | What It Does | When to Increase |
|---|---|---|---|
| Brightness | −100 to +100 | Adds/removes light uniformly across all tones | Image looks dark overall |
| Contrast | −100 to +100 | Increases separation between light and dark areas | Image looks flat or milky |
| Saturation | −100 to +100 | Makes colours more vivid or more muted | Colours look dull; set −100 for B&W |
| Sharpness | 0 to +100 | Unsharp mask — enhances edge contrast | Image looks soft or slightly blurry |
| Exposure | −100 to +100 | Multiplicative brightness — affects highlights most | Similar to brightness but more natural for overexposure correction |
| Temperature | −100 to +100 | Shifts colour toward cool/blue (−) or warm/orange (+) | Fix colour casts; warm up skin tones |
| Highlights | −100 to +100 | Adjusts the brightest areas independently | Set negative to recover blown-out skies or windows |

AI Smart Modes: Portrait, Landscape, Document
Portrait Mode
Lifts shadows (opens up facial detail in underlit areas), adds warm temperature (flatters most skin tones), applies balanced contrast without making skin look harsh, and boosts brightness gently. Produces a natural-looking portrait without the over-processed look of heavy filters. Best for: headshots, profile photos, family portraits, LinkedIn pictures.
Landscape Mode
Boosts contrast and clarity, lifts greens (more vivid foliage), slightly cools temperature (enhances sky blues), increases saturation, and reduces haze through midtone contrast. Best for: nature, travel, architecture, outdoor scenes.
Document Mode
Maximises contrast, converts to near-monochrome (eliminates scan lighting colour cast), applies heavy sharpening, and boosts exposure of white background areas. Result looks like a clean, printed document. Best for: scanned documents, whiteboard photos, handwritten notes, receipts.
Best Enhancement Techniques by Photo Type
E-commerce product photos
Accurate colour representation matters most. Use Studio Pro filter or manual: Temperature to neutral (0), Contrast +15 to +25, Brightness +5, Sharpness +25. Avoid warm or saturation-boosting filters — they misrepresent product colours and can lead to customer returns.
Food photography
Food looks best warm and saturated. Use IG Glow or Warm Sunset filter, then fine-tune: Temperature +10 to +20, Saturation +15 to +25, Highlights −10 to recover blown-out whites on plates. Cool-toned filters make food look unappetising.
Low-light and indoor photos
Start with Auto Enhance — it identifies and corrects underexposure automatically. Then manually: Brightness +20 to +40, Contrast +15, Sharpness +15 (carefully — sharpening noisy low-light images amplifies grain). If there's an orange indoor lighting cast, set Temperature −15 to −25.
Document scans and whiteboards
Use Document Mode or the Doc Scan filter: maximum contrast, near-monochrome, heavy sharpening. For colour documents (diagrams, annotated slides), skip the greyscale and use only high Contrast and Sharpness.
