In Adobe Photoshop, a raw edit layer enables non-destructive editing of raw image data. It preserves the original raw file information, allowing for adjustments to be made without permanently altering the underlying image. This provides greater flexibility and control over the editing process, especially when working with high-quality raw images.
Raw edit layers are particularly useful for photographers who want to fine-tune exposure, white balance, and other image parameters without compromising the original data. By keeping the raw information intact, photographers can make adjustments, experiment with different settings, and revert to the original state as needed, ensuring the preservation of the original image.
