Brightness adjusts the overall lightness or darkness of an image, while contrast controls the difference between light and dark areas. Increasing brightness makes the entire image lighter, while increasing contrast makes dark areas darker and light areas lighter, creating more visual impact.
Use the brightness slider to increase the brightness value. Start with values between +20 to +50 depending on how dark the image is. You can also use the "Brighten" preset for a quick adjustment.
The histogram displays the distribution of tones in your image from dark (left) to light (right). A well-balanced image typically has a histogram that spans the full range without clipping at either end.

Brightness and contrast adjustments are the foundation of professional image editing. Whether you're fixing poorly exposed photos or creating dramatic artistic effects, understanding these two fundamental controls can transform your images from ordinary to extraordinary. Let me guide you through the science and art of mastering image tonality.
Brightness adjusts the overall luminance of your image. Think of it as adding or removing light evenly across all pixels. A +50 brightness adjustment adds the same amount of light to every pixel, whether it's already bright or dark.
Contrast controls the difference between light and dark areas. Increasing contrast makes dark areas darker and light areas lighter, expanding the tonal range. Decreasing contrast compresses the tonal range, creating a flatter, more muted look.
Increase brightness (+20 to +50) and add slight contrast (+10 to +20) to recover details.
Decrease brightness (-20 to -40) and increase contrast (+15 to +30) to add depth.
Increase contrast (+25 to +50) and add slight brightness (+5 to +15) for vibrancy.
Pro Tip: Aim for a histogram that spans the full width without clipping at either end. Gaps at either extreme mean you're losing detail in shadows or highlights.
Increase brightness (+40 to +60) and decrease contrast (-20 to -40) for ethereal, dreamy images perfect for fashion and product photography.
Decrease brightness (-10 to -20) and increase contrast (+40 to +60) for moody, dramatic images with crushed blacks and rich contrast.
Slight decrease in brightness (-5 to -15) with moderate contrast (+20 to +30) creates that classic film look with faded highlights.
Problem: Images lose all detail in highlights, creating a flat, unnatural appearance.
Solution: Keep brightness adjustments below +60. Use the histogram to ensure highlights aren't clipping off the right edge.
Problem: Shadows become pure black with no detail, creating harsh transitions.
Solution: Monitor the left side of your histogram. If it's stacking against the left edge, reduce contrast slightly.
Problem: Making adjustments based only on visual appearance, not data.
Solution: Always check the histogram. It shows you exactly what's happening to your image data.
