Blue Hour The blue hour is a period of time that occurs twice a day, just before sunrise and after sunset, when the sky takes on a deep blue hue with soft, diffused light. It is named for the bluish quality of the light during this time, which is caused by the scattering of shorter blue wavelengths in the atmosphere while longer red wavelengths diminish. The blue hour presents a unique and captivating opportunity for photographers to capture scenes with a tranquil and atmospheric quality. The soft, diffused light of the blue hour can enhance landscapes, cityscapes, and architectural photography, creating images with a serene and ethereal ambiance. |
