Understanding the Blood Moon Phenomenon
A Blood Moon 2025 occurs during a total lunar eclipse when the Earth positions itself directly between the Sun and the Moon, casting its shadow upon the lunar surface. Unlike solar eclipses that require special eye protection, lunar eclipses are completely safe to view with the naked eye and offer a prolonged spectacle often lasting several hours. The term "blood moon" refers to the reddish-copper hue the Moon takes on during totality, caused by Rayleigh scattering of sunlight through Earth's atmosphere.
This atmospheric filtering effect bends red wavelengths of light around our planet while blocking blue light, essentially projecting all of Earth's sunrises and sunsets onto the Moon's surface. The intensity of this coloration can vary based on atmospheric conditions, with volcanic activity and pollution levels influencing the depth of red observed during the Blood Moon 2025. According to NASA's Eclipse Bulletin, the September 2025 event promises particularly favorable viewing conditions with an expected duration of 1 hour and 42 minutes of totality.
The Blood Moon 2025 will display the characteristic reddish-copper color caused by atmospheric filtering of sunlight.

Advanced Photography Techniques for the Blood Moon 2025
Capturing stunning images of the Blood Moon 2025 requires preparation and understanding of lunar photography techniques. Unlike typical moon photography, eclipse conditions present unique challenges due to rapidly changing light conditions throughout the event. Professional astrophotographers recommend a multi-camera setup to document different phases effectively.
For the partial phases, use a telephoto lens of at least 300mm ( ideally 500-800mm) on a sturdy tripod with a remote shutter release to minimize vibration. During totality, the Moon's brightness decreases significantly, requiring longer exposures and higher ISO settings. Bracket your exposures widely (1/1000s to 2 seconds) to capture the dynamic range between the darker eclipsed portion and the still-bright edge of the Moon. For composition, consider including foreground elements like silhouetted trees or architecture to provide scale and context to your Blood Moon 2025 images.
Recommended Camera Settings for Blood Moon Photography

|---|---|---|---|---|
| Partial (beginning) | f/8 - f/11 | 1/500 - 1/1000s | 100 - 400 | 300mm+ telephoto |
| Partial (advanced) | f/5.6 - f/8 | 1/125 - 1/250s | 400 - 800 | 300mm+ telephoto |
| Totality (mid-eclipse) | f/4 - f/5.6 | 1s - 4s | 800 - 1600 | 200mm+ telephoto |
| Totality (bright edge) | f/5.6 - f/8 | 1/30 - 1/60s | 400 - 800 | 300mm+ telephoto |
| Wide-field composition | f/2.8 - f/4 | 5s - 15s | 1600 - 3200 | 24-70mm with foreground |
