Steps include (1) Photomerge (File/Automate/Photomerge) of the four images used to create the panorama, (2) crop to desired image, (3) sharpen, (4) "save as" then close and reopen as the newly saved image, (5)apply the "Ansel Adams Style" grayscale conversion using the channel mixer [starting settings @ R+160%, G+190% & B-200%]with monochrome box checked [adjust brightness with the Constant slider or by bringing the Green channel down], (6)create a duplicate background layer, set the forground color at black and resize canvas to get a black border then resize image for presentation/printing and one more unsharpen mask pass.

I added text and shape (copyright) with layer styles (inner glow and drop shadow) to add effects for my signature.
