Reel #4 of (...) is a recapitulation of the primary variations of scratched (on black leader) shapes and additive colors (i.e. those which are composed of toned light in the step printing process) as well as the solarizations (i.e. the combination of negative and positive images of the scratches) and the negative imagery itself (with its almost phosphorescent negative coloration): these visual themes (forms, textures and tones) eventually resolve themselves into an amalgam, as it were - something that seems "new", a "breakthrough", so to speak, but is actually combos of earlier variants.
