From memory I do not think the D60 has an auto bracket, so you will have to do it manually. Few choices, shoot in NEF and use photoshop to alter the file and merge the altered images, or shoot several shots, of the same scene and use Photomatix to merge the shots but make sure you use a tripod to take those shots.
