Light a face filmed against a window

Who it is for

Anyone who filmed with a window or bright light behind them and got a dark face.

What it does

• A soft oval fill light that follows your face, smoothed so it never jitters
• A gentle shadow lift that fades out above mid-grey
• Highlight protection with a soft roll-off
• A before and after preview and adjustable strength

My face is too dark in interview.mp4 because of the window behind me. Show me a before and after first, then fix the whole video.
