There is an unusually strong solar storm this evening, causing "Northern Lights" in unusual places (much farther south than usual).
This is close to the peak of a multi-year solar cycle.
Because of the reposrts that the Lights would be visible in unusual places, we decided to look.
Note that Lights are usually show MUCH better on photographs than using the plain eyeball method (something to be aware of if one is planning a special trip to see the Lights).
Nothing was in view, which wasn't really a surprise.
Then DH used his iPhone to take a picture. Wow! Faint pink in one area! Nice!
He took another in a different direction. Still faint pink, but still "Lights", and more color than when we were on a Hurtigruten cruise along the Norwegian coast, but we only used our eyeballs. (We were part of an astromomy group, and the astronomer was going to be getting much better photos than anything we could get, etc.)
Then DH realized he had his Flash on.
Okay, so he turned that off, and we figured maybe we'd see the Lights a bit better if there wasn't artificial light interfering.
Wrong! WithOUT the Flash, there was NO color, NOTHING visible in the photo.![:confused]( "confused")
Can anyone explain why a flash on a little iPhone would affect, in a *helpful* way, the image of Northern Lights by that iPhone camera?
Thanks!
