Nikon D90 Image Overlay, Select Image overlay, Display NEF RAW images, Highlight a photograph

Image Overlay

Image overlay combines two existing NEF (RAW) photographs to create a single picture that is saved separately from the originals; the results, which make use of RAW data from the camera image sensor, are noticeably better than overlays created in an imaging application. The new picture is saved at current image quality and size settings; before creating an overlay, set image quality and size (pp. 62, 63; all options are available). To create an NEF (RAW) copy, choose an image quality of NEF (RAW).
