Forget complex channels and manual selections. With Pixelcut's AI, you can apply intricate luminosity masks simply by describing your desired edit. Want to make a sunset sky more dramatic without altering the foreground? Just say so. Our tool intelligently selects pixels based on their brightness to make precise adjustments to highlights, midtones, and shadows. This approach gives you professional-level control over the light in your photos, perfect for enhancing landscapes or portraits, without the steep learning curve of traditional software.

Master Light with AI-Powered Selections

The right 'after' side is perfectly balanced, showing vibrant colors and full detail in both the sky and rocks, illustrating the power of luminosity masks.
High-contrast scenes, like a bright sky over a shadowed landscape, often challenge cameras. Instead of manually blending multiple exposures, you can use our AI to achieve a similar, high-dynamic-range effect from a single image. Use simple text prompts like "recover the details in the bright clouds" or "lighten the shadows on the hill." Our AI intelligently adjusts specific brightness ranges to create a single, beautifully balanced photo where every detail, from the brightest highlights to the darkest shadows, is clear and impactful.

Achieve Perfect Exposure Blending Instantly

Luminosity masks are about more than just brightness; they allow for incredibly targeted color corrections. For instance, you can enhance the warm orange and pink tones of a sunset without making the rest of the image look unnatural. Tell the AI to "add a cool blue tint to the shadows" or "make the midtones in the grass more vibrant." The edits are applied only to your specified tonal range, giving you surgical precision over the mood and atmosphere of your images through simple, conversational prompts.
