Lightening Presets Explained
Gentle Brightening
A subtle enhancement that adds just enough brightness without looking unnatural. This preset applies a modest 15% brightness increase while slightly lifting shadows and preserving details in highlights. Perfect for images that need a minor boost in exposure.
Moderate Lightening
A balanced adjustment for underexposed photos that need significant correction without appearing artificial. This preset increases brightness by 30%, enhances shadows considerably, and applies a touch of contrast through whites and blacks adjustments. Ideal for everyday photo correction.
Shadow Recovery
Specifically designed to reveal details hidden in dark shadows while minimally affecting well-exposed areas. This preset uses a targeted approach with a 50% shadow boost combined with modest overall brightness. Perfect for backlit subjects or photos with dark foregrounds and properly exposed backgrounds.
Preserve Highlights
Carefully brightens dark and mid-tone areas while actively protecting highlights from becoming overexposed. This preset uses negative values for the highlights slider (-30%) to maintain detail in bright areas while still lifting shadows by 30%. Ideal for high-contrast scenes like sunset photos.
Dramatic Exposure
A bold adjustment that substantially brightens the image for a high-impact look. This preset applies a significant 50% brightness increase with strong shadow recovery and contrast enhancement. Use for creative effects or severely underexposed images.
Advanced Mode Controls
Exposure
The master control that affects the overall brightness of the image. Similar to increasing exposure in a camera, this slider brightens all tones but has the strongest effect on midtones. The scale ranges from 0 (no change) to 2 (double brightness).
Shadows
Specifically targets and brightens the darker areas of your image without affecting highlights. Higher values reveal more detail in shadows. This slider is particularly useful for recovering details in backlit subjects or improving underexposed portions of otherwise good photos.
Highlights
Controls the brightness of the lightest areas in your image. While normally used to recover detail in bright areas (with negative values), in a lightening tool, you can use this to protect highlights from becoming overexposed when brightening the rest of the image.
Whites & Blacks
Fine-tune the very brightest (whites) and very darkest (blacks) parts of the image. These sliders help adjust the overall contrast while lightening. Increasing whites creates brighter white points, while increasing blacks lifts the darkest shadows.
Gamma
Adjusts the brightness of mid-tones specifically, with less effect on shadows and highlights. Values above 1.0 brighten midtones, while values below 1.0 darken them. This control helps achieve a more natural look when brightening, as it mimics how our eyes perceive brightness.
Frequently Asked Questions
When should I use Simple vs. Advanced mode?
Use Simple mode for quick adjustments when you just need basic brightening with minimal effort. Choose Advanced mode when you need precise control over different tonal ranges, such as recovering shadow details while protecting highlights from becoming overexposed. Advanced mode is also better for high-contrast images that need selective adjustments.
What does "Preserve Colors" do?
The "Preserve Colors" option maintains the original color relationships when brightening your image. When enabled, each color channel (red, green, blue) is adjusted proportionally, keeping the color balance intact. When disabled, colors may shift slightly as the tool uses HSL (Hue, Saturation, Lightness) adjustments, which sometimes produces a different look. Try both options to see which works best for your image.
Why do my highlights look washed out after lightening?
This happens when bright areas become overexposed during lightening. To fix this, use the Advanced mode and set the Highlights slider to a negative value (like -20%) to protect these areas. Alternatively, try the "Preserve Highlights" preset, which is specifically designed to prevent this issue.
Can this tool fix very dark or almost black images?
While our tool can significantly improve underexposed images, extremely dark photos may have limited recoverable information. For best results with very dark images, use Advanced mode with high shadows and blacks values, moderate exposure increase, and a gamma adjustment above 1.1. The "Dramatic" preset may also help, but be aware that heavily lifting shadows in nearly black areas can introduce noise.
Does lightening an image reduce its quality?
Significant lightening can potentially reveal or amplify image noise, especially in areas that were originally very dark. This is a limitation of the original captured data, not the tool itself. For best quality, make modest adjustments and use the preview to find the optimal balance between brightness and image quality. The Advanced mode offers more control for preserving quality.
