Frequently Asked Questions
How does the shadow adjustment algorithm work?
Our tool uses advanced luminance-based shadow detection that analyzes the brightness of each pixel. It creates a shadow mask that applies stronger effects to darker areas while preserving highlights and midtones. This ensures natural-looking results without overexposing bright areas.
What's the difference between negative and positive values?
Negative values (-100 to 0) darken shadows, creating more dramatic contrast and moodier effects. Positive values (0 to +100) lighten shadows, revealing details in dark areas and reducing harsh contrasts. Zero means no adjustment is applied.
Is my image data safe and private?
Absolutely! All image processing happens directly in your browser using JavaScript. Your photos are never uploaded to our servers or stored anywhere. The shadow adjustment is applied locally on your device, ensuring complete privacy and security.
Will the image quality be affected?
The output image maintains the same resolution and format as your original. We use high-quality processing that preserves image detail. Only HEIC and GIF files are converted to more compatible formats (JPEG and PNG respectively) for web compatibility.
Can I adjust shadows in specific areas only?
This tool applies shadow adjustments globally across the entire image. However, our smart algorithm automatically focuses the effect on darker areas (shadows) while leaving bright areas largely unchanged, creating natural-looking results without the need for manual selection.
Why do HEIC files need conversion?
HEIC files (used by iPhones) need to be converted to JPEG because web browsers don't natively support the HEIC format. Our tool automatically handles this conversion while maintaining high quality, so you can seamlessly edit iPhone photos.
Does this work on mobile devices?
Yes! The shadows adjustment tool is fully responsive and optimized for mobile devices. The interface adapts to smaller screens, and you can easily upload photos directly from your device's camera or photo library for instant shadow correction.
What types of photos benefit most from shadow adjustment?
Photos with strong lighting contrasts benefit most - such as backlit portraits, sunset/sunrise scenes, indoor photos with window light, and outdoor photos with harsh shadows. The tool is also excellent for artistic enhancement of architectural and landscape photography.
