When selecting my photographs I uploaded them all into photoshop so that I could see them on a large scale. From there I could already narrow it down, as some were clearly not right for the finished piece.
I then started to play around with editing. Mostly I changed the brightness and hue of the images. I found that lowering the hue on the best images, gave them all a similar look which fit the theme of the piece. I tried to avoid bright colours, as the piece is quite serious and I wanted the images to resemble that.
The images below demonstrate before and after photoshop.
