The sun is setting. Two character gaze longingly into each other's eyes. The camera shifts to a profiled two shot, with the setting sun shimmering between them in the background. Their faces now silhouettes, the characters move closer, slowly covering the sun until at last... their lips meet.
A fairly common kiss, combining the power of the sun with the Power of Love. Variations include kissing in front of the moon or some other light source, or holding each other without kissing. Expect lots and lots of Lens Flare.
Interesting note: From a lighting standpoint, when the actors are backlit their faces are obscured or silhouetted. Once they kiss, they block out the light coming through, meaning the camera can finally see their faces. A kiss turning shadows into people... There's something symbolic in that.
- In the final episode of F-Zero: GP Legend, Rick Wheeler meets his girlfriend, Haruka Misaki, at the same city park where he planned to propose to her 150 years ago. She happily accepts the ring and the two kiss, blocking the sun.
- The Greatest Showman: Phillip and Anne at the end, during the reprise of "The Greatest Show", with a bright stage light.
- Inverted Trope in Incest! The Musical. When they kiss during the song "I Know It's Wrong", you can see their faces right up until they kiss, at which point a bright gym light obscures them.
- The Island: Right before Lincoln Six Echo and Jordan Two Delta launch their rescue mission, they discuss what they'll do after, and then, Cue this trope...
- Pride & Prejudice (2005) has one of these near the end, when Darcy and Lizzie confess their love. Of course, it's sunrise, not sunset, and there's technically no kiss, but the concept is there.
- Occurs in The Princess Bride toward the beginning; combined with sunset for a nice effect, and promptly spoiled by the grandson interrupting:
Grandson: Is this a kissing book?
- Slumdog Millionaire has one in the last few seconds of the film.
- In True Lies, there's a variation involving Jamie Lee Curtis and Arnold Schwarzneggar. Instead of the sun, their kiss blocks out a nuclear explosion.
- The Last Jedi features a maybe-platonic, maybe-not variant between Finn and Rose during the climax. After Rose crashes her speeder to save Finn's life, she kisses him, and her head blocks the explosion from the First Order breaching the Resistance hideout's bunker door. It underscores what she just said about how saving what you love is more important than fighting what you hate.
- Doctor Who: In "The Parting of the Ways", when the Doctor and Rose kiss when he takes the power she absorbed out of her. Bonus points for having the freakin' Time Vortex providing the background light.
- Barry and Iris do this for their first kiss in The Flash.
- Luke and June have this lighting for their first kiss in a flashback in The Handmaid's Tale.

- In Once Upon a Time, Robin and Marian in "Heart of Gold", and Hercules with Snow White in "Labor of Love".
- In Primeval, Cutter and Claudia have this in episode 5 of Series 1. It's a much-awaited moment and arguably one of the best in the series.
