White Balance Highlight Recovery

Free Photoshop Plugins

This plug-in lets you quickly white balance an image by drag-selecting a neutral area to eliminate the color cast. It will also recover highlight detail that is normally clipped and discarded by the white balance process. Applying gain on the R, G, and B channels will cause one or two of these channels to exceed white level. Normally these values above white level are clipped. However, it is possible to use this information to make an intelligent guess about the other channel(s) that did not have gain applied. The ungained channel(s) will usually contain clipped values; highlight recovery will make an intelligent guess about what the original unclipped values were. If the original image does not contain perfect white balance, then highlight recovery offers the possibility of increasing dynamic range compared to no highlight recovery.
