Blue Hour Calculator

• Use a tripod - exposures during blue hour are typically 1-30 seconds

• Set white balance to daylight (5500-6500K) for deeper blue tones

• Ideal for cityscapes when artificial lights balance with sky

• Evening blue hour is preferred as city lights are fully on

• Use ISO 100-400 and f/8-f/11 for sharpest results

• Bracket exposures for HDR to capture full dynamic range
