I started with an arrangement of unedited photos, all the same size and tone. I then edited an individual image to the specifications I wanted, then copied these edits to the rest of the images. This allowed them to remain the same, yet in black and white.

I then used the PhotoMerge algorithm within Photoshop to combine the photos together and create a singular large image. This is done by File/Automate/Photomerge. After dropping the files within the algorithm and waiting for the process to complete, this final product was produced.
