The top photographic print is a straight-forward darkroom produced monochrome print. The second and bottom print is a monochrome photographic print that has been blue toned. Blue toning is a fairly simple process involving just a two bath (tray) process. The first tray (bath) is the blue toning chemical solution and the second bath (tray) is a plain water with salt added to the wash. After this process the print is then properly washed and dried as per a normal print.
You can see the difference to the overall tonal quality and depth that toning brings to a print.
