• Mastering natural light usage enhances the authenticity and visual appeal of documentary-style journalism

Color temperature

• Measured in Kelvin (K), ranging from warm (2000K-3000K) to cool (6500K-10000K)
• Golden hour light (shortly after sunrise or before sunset) produces warm, soft light around 3200K
• Midday sunlight typically measures around 5600K, appearing cooler and more neutral
• Overcast skies can produce a cooler light temperature, often exceeding 7000K

Intensity and direction

• Light intensity varies throughout the day, peaking at midday and diminishing towards dawn and dusk
• Direct sunlight creates harsh shadows and high contrast, while diffused light (cloudy days) softens shadows
• Side lighting enhances texture and depth, while backlighting creates silhouettes and rim lighting effects
• Angle of the sun changes seasonally, affecting shadow length and direction

Seasonal variations

• Summer sunlight tends to be more intense and direct, creating stronger shadows and higher contrast
• Winter light is often softer and more diffused, particularly in higher latitudes
