Dropped $18 on a used ring light at a garage sale and it caught a fake in 2 minutes
My cousin sent our family group chat a clip of a famous actor saying something wild, and I could just tell something was off. I set up that cheap ring light next to my laptop and replayed the clip in slow motion, and the shadows on his neck kept flickering in a weird pattern that doesn't happen with real lighting. A real light moves on skin smooth, but this one jumped every few frames. Does anyone else use plain old desk lamps or lights to spot the shadow errors, or is that too low tech?

Lighting is the one thing most people never think to check because it feels too simple to matter. That flicker pattern you caught is basically the software guessing at where shadows should land between frames, and it fails hardest on the neck and jaw where the curves change fast. A plain desk lamp angled from one side does the same job as your ring light, sometimes better, because a single hard light source makes every bad edge stand out. You can also just drag the clip into any editor and step frame by frame, but honestly the lamp trick works because your eye notices the jump before your brain can talk you out of it. Cheap tools plus slow motion beats expensive software most days.
