Exposure blending in Photoshop is a technique used in photography to combine multiple exposures of the same scene, each with different exposure settings, into a single, well-exposed image. Exposure blending allows photographers to capture a wider dynamic range than what a single exposure can handle, resulting in an image that accurately represents both highlight and shadow details in a high-contrast scene. It's a powerful technique for creating stunning, balanced photographs, especially in landscape photography where lighting conditions can vary widely.
