Apply a Split Screen treatment by arranging two synchronized versions of the original view in adjacent panels with a clean vertical divider. Introduce modest differences in exposure and color temperature, with crisp rectangular boundaries and no blending between views. Within each panel, keep the original subject and composition.
Show the same action from two contradictory perspectives2.
Background
Split screen has been used since early film experiments to create multiple settings and subjective comparisons. Abel Gance's Napoléon made monumental multiple images famous in 1927. Columbia also shows the telephone montage of Pillow Talk and the quadruple image of Timecode. The effect differs from parallel editing: The audience sees the views simultaneously, rather than switching between individual, full-screen shots.
Distinction
Images visible at the same time do not necessarily represent events recorded simultaneously. The division can suggest proximity, make comparisons, or emphasize differences.
Aftermath
Simultaneity is adesign statement, not automatically documentary evidence.
