Color Adjustments¶
Adjust image color properties including brightness, contrast, saturation, and gamma correction.
Parameters¶
brightness
¶
Adjust image brightness levels.
Type: float
Range: -100
to +100
Default: 0
(no adjustment)
contrast
¶
Adjust image contrast levels.
Type: float
Range: -100
to +100
Default: 0
(no adjustment)
saturation
¶
Adjust color saturation intensity.
Type: float
Range: -100
to +100
Default: 0
(no adjustment)
gamma
¶
Apply gamma correction for brightness curve adjustment.
Type: float
Range: 0.1
to 5.0
Default: 1.0
(no correction)
Usage¶
Individual Adjustments¶
Increase brightness by 20%. Increase contrast by 30%. Reduce saturation by 50%.Combined Adjustments¶
Apply multiple color corrections.Gamma Correction¶
Apply gamma correction for display optimization.Color Adjustment Guide¶
Brightness¶
- Positive values (+1 to +100): Lighter, brighter images
- Negative values (-1 to -100): Darker images
- Use cases: Correct underexposed photos, create mood
Contrast¶
- Positive values (+1 to +100): Increased difference between light and dark areas
- Negative values (-1 to -100): Reduced contrast, flatter appearance
- Use cases: Add punch to flat images, soften harsh lighting
Saturation¶
- Positive values (+1 to +100): More vivid, intense colors
- Negative values (-1 to -100): Muted colors, approaching grayscale at -100
- Use cases: Enhance sunset photos, create vintage looks
Gamma¶
- Values < 1.0: Darker midtones, higher contrast
- Values > 1.0: Brighter midtones, lower contrast
- Use cases: Display calibration, creative tone mapping
Use Cases¶
Photo Enhancement¶
General photo improvement.Vintage Effect¶
Create aged, muted appearance.High Key Effect¶
Bright, airy portrait style.Low Key Effect¶
Dark, dramatic mood.Web Optimization¶
Enhance for web display with format optimization.Processing Order¶
Color adjustments are applied in this sequence:
1. Gamma correction
2. Brightness adjustment
3. Contrast adjustment
4. Saturation adjustment
This order ensures optimal results and predictable behavior.
Best Practices¶
Natural Enhancement¶
- Keep adjustments subtle (±20 range) for natural results
- Use gamma for overall tone before brightness/contrast
- Adjust saturation last to fine-tune color intensity
Creative Effects¶
- Extreme values (±50 to ±100) for artistic purposes
- Combine with style effects for complex treatments
- Test across different image types
Performance¶
- Multiple color adjustments are processed efficiently in single pass
- Results cached at edge for subsequent requests
- Combine with other parameters for optimal processing
