Yes, image saturation can affect both the file size and image quality. When you increase an image's saturation, the image's color data also increases. Higher saturation means more color information needs to be stored in the file, leading to a larger file size. Also, excessive saturation can lead to a loss of image quality. If saturation is pushed too far, it can result in color clipping, where the colors become so intense that they exceed the gamut that the image format can represent. To strike a balance between image quality and saturation, it's crucial to use editing tools that allow for precise control over saturation levels. Use Luminar Neo to have exact control over saturation.
