During raster image editing, it is important to have consistent brightness levels when creating photographs for a product catalog, Portfolio, or an online gallery. While batch adjustments can be a good reference point, you'll need to make individual corrections if lighting varies. Visuals Clipping suggests checking for differences in lighting between images and checking for highlights and shadows before export. Photographs are edited in a consistent manner to create a unified, cohesive visually pleasing set that does not appear too similar.
