Create a mesmerizing nighttime scene of a Japanese floating lantern festival, where hundreds of glowing paper lanterns drift over a still body of water. The artistic style should be a combination of realism and dreamlike fantasy, using a muted color palette with soft, glowing oranges and gentle blues. The medium is digital painting with watercolor-like blending for the sky and water, and fine, crisp details for the lanterns. Camera settings emulate a long exposure (shutter speed: 2 seconds) to capture the reflection of the lanterns in the water, with a wide-angle lens (24mm) for a sweeping view. Soft, ambient lighting comes from the lanterns themselves, with the background fading into the dark horizon, and the foreground showing the lanterns closest to the viewer. The image should evoke a sense of peace and wonder, inviting viewers to share the serene, otherworldly moment. This type of content taps into cultural aesthetics and serenity, which Instagram audiences find captivating.
