Many Nikon digital cameras feature retouching options right in the camera, in the Retouch Menu. Some of the things you can do include straightening a horizon or cropping an image square to share on social media. Retouch options vary by camera, so check your camera’s user’s manual to see which ones your camera can perform. Retouched images are saved as separate files on your media card, along with the original untouched file.
