Mutter never transitioned to the cut and paste technique afforded by Photoshop and similar software but recreated every original print in the darkroom as he thought this was the only way that they were truly "originals"

fascinating approach to photomontage. I believe he has used the dodge technique in the darkroom, exposing part of the photo paper with one part of an image and blending in the other.
that and obviously amazing skill at it
