The universal night lamp Guiding the world with borrowed glow. There's an Oscar winning movie with this name

A gentle nudge, the smallest spark, often leads to a grand embark. At the summit of a journey's start, I'm the edge, the crest, the finest part.

Silent thinker, housed in metal, counting in light and dark, orchestrating digital symphonies without a sound.

I shoot but I don't kill, What I capture is moving still, I often stand between lights and action!

I take what’s old and worn and used, What’s cracked or crushed or once abused. I sort the tired from the true, Then turn them into something new. I shrink the waste the world is piling. What am I, always re reviving and smiling?
