GROOVE / STEP / DIRECTION
Image Guide
Best search: escalator steps close up / escalator grooves / escalator metal texture / moving stair lines. Avoid: escalator safety advice / maintenance tutorial / repair instructions / accidents / operational guidance. Image Guide is part of the Gervali archive, looking closely at form, material, spacing, and visual rhythm within the escalator grooves & step lines theme.

Visual principle
Treat escalator surfaces as industrial repetition, grooves, direction, and metal rhythm rather than operation or safety advice.
What to notice
Look at repetition, edge profile, spacing, material texture, negative space, reflected light, and the way one small object becomes a visual system when viewed closely.
Editorial use
Alternate one strong anchor image with close crops, isolated details, and wider surface context so the archive feels specific rather than templated.
