Second Curtain: a slow sync flash AI photoshoot
City lights drag across the frame for 1/8 s, then a rear-curtain flash freezes the face: that is the slow sync flash recipe behind Second Curtain. Five frames and a detail mix a ghosted body, amber trails and a crisp white-lit subject.

About the rear-curtain flash look
A direct on-camera flash fires at the end of the exposure, so the light trails end at the sharp, frozen subject. During that eighth of a second the camera twists and drags, pulling street lamps, tail lights and shop signs into amber and red streaks. A translucent double outline follows the body. The 24 mm lens works close at f/5.6, and ISO 3200 adds noise to the shadows.
Clothes, place and when to pick it
Everything here is chosen to catch the flash: a cropped liquid-silver puffer, a black mesh top, wide black pants, white chunky sneakers, clear wraparound sport glasses and a silver chain. Parked cars and night streets supply the color. It fits a nightlife promo, a single cover or a profile picture with your face sharp inside the chaos.
