I did a number of sunset photos last year, some far more grandiose. However, this one stands out as a bit different. It’s more intimate feeling despite an entire city spreading out behind them.
Sunsets actually require some technical shooting to get right. In this case I had a flash off camera to the right to give us strong directional light (and to avoid turning them into silhouettes due to the fact that all the sunlight is coming from BEHIND them). I put a warm color gel on the flash to match the color of the setting sunlight.
The perfect position for the sun lasts only seconds, so it takes a little preparation and a lot of fast shooting to make something like this happen. It’s no time to be fiddling with the camera.
