Why Do Earth's Colors Appear Muted in New Photos From Artemis II?
NASA said the Artemis II image used ISO 51,200 and was shot in shadow, making Earth look less vivid than Blue Marble.
- NASA mission commander Reid Wiseman posted a "Hello World" photo from the Artemis spacecraft on April 2, drawing criticism from people comparing the colors unfavorably to the iconic 1972 Apollo "Blue Marble" photo captured by Harrison Schmitt.
- Differences in vividness stem from camera settings and positioning, not pollution; the modern photo utilized a 51,200 ISO, whereas the 1972 image relied on 64 ASA film, creating a 9-stop sensitivity gap.
- Photography educator Jared Polin explained in an emailed response that the images depict different lighting scenarios: "One is shot with the sun lighting up the earth, and the other, the Earth is blocking the sun, meaning it."
- Wiseman required a 51,200 ISO setting because the spacecraft was on the opposite side of Earth from the sun, making the planet appear dark; he captured another image to illustrate the "Dark Side."
- Soon after the photo was taken, the crew traveled 100,000 miles from Earth and was quickly gaining on the destination with 160,000 miles remaining, while the image displays stunning auroras showcasing modern camera capabilities.
