wow, i don't know what this is, or even understand how it was made
but this looks like a film still from a horror movie like eraser head or attack of the 50 foot corpse.
hauntingly beauiful !
so, this is straight gum bichromate, not an overlay on another print ( pt/pd/cyanotype/silver &c ) to give color or enhancement ?
i've seen your video series about gum OVERS and pin registered negatives ... and the process solarizes too !
