📊 Understanding Brightness, Contrast & Saturation

• Brightness: Controls the overall lightness or darkness of the image. Increase to lighten a dark photo, decrease to darken an overexposed shot. Range: -100 (very dark) to +100 (very bright).
• Contrast: Adjusts the difference between the darkest and lightest areas. Higher contrast makes whites whiter and blacks blacker, adding depth and drama. Lower contrast creates a softer, flatter look.
• Saturation: Controls the intensity of colors. Higher saturation makes colors more vivid and punchy; lower saturation creates a muted or black‑and‑white effect. At -100, the image becomes grayscale.

🎯 Recommended Settings for Different Scenarios

• Portrait photos: Slight brightness +5 to +10, contrast +10 to +20, saturation +5 to +15 for natural skin tones.
• Landscape photos: Contrast +20 to +40, saturation +15 to +30 to make skies and foliage pop.
• Product photography: Brightness +0 to +10, contrast +15 to +25, saturation +10 to +20 for clean, vibrant shots.
• Black & white conversion: Set saturation to -100, then adjust brightness and contrast for artistic effects.
• Underexposed images: Increase brightness (+20 to +40) and contrast (+10 to +20) to recover details.

❓ Frequently Asked Questions

Q: Does adjusting brightness/contrast/saturation reduce image quality?
A> No – the adjustments are applied mathematically to the pixel data. As long as you don't over‑adjust, quality remains excellent. Extreme values (e.g., +100 brightness) may cause clipping, but you can always reset or adjust gradually.

Q: Can I adjust only one parameter?
A> Yes – each slider works independently. You can change just brightness, just contrast, or just saturation, or any combination.

Q: What file formats are supported?
A> JPG, PNG, and WebP. Output is always PNG (lossless) to preserve quality.

Q: Is there a file size limit?
A> No artificial limit, but very large images (over 100 MB) may be slower depending on your device memory.

Q: Why does the adjusted preview sometimes look different from the final download?
A> The preview is generated from the same canvas data as the download. They should match exactly. If you see a difference, try refreshing the page.
