Aurora borealis - What is reality?
When aurora is low, it appears as a white widespread brightness in the empty sky.
Why white?
Because of when solar wind is not so powerful, the energy of photons emitted by oxygen (molecular and atomic) and by nitrogen, are so low that we watch light using only rod cells of our retina, and rod cells permits us to watch only in black and white. Conversely, sensors of a reflex/mirrorless/smartphone camera, can watch full colors! So when we see a white brightness, it has colors... It is very strange, but it is a fact, and I reflect about what is reality and what is not reality. Our senses are limited, so we can't trust in our sense to understand reality. Also low intensity auroras is colorful, but we can't watch colors!
Here an example: this is a long exposure (30 seconds) pictures where auroras appeared as white:
But wow! There are many colors!
When auroras increases its intensity (more density in solar wind), colors suddenly appears! Like in the following pictures.
In the first, you can see also last twilight colors on the horizon:
And the last one, one of my favorite!
That auroras was fully visible by our retina, not only with rod cells, but with the greater contribute of cones cells inside retina, so colors appeared (cones cells are responsible of colors) not only with sensors, but also with naked eye!
In last image I have joined two different shots (some seconds between first and second shot), to recreate the reflection of the green on ocean surface, because of a wide angle (24mm) was not enough!
Thanks to my friend, director and physicist Luca Giberti for technical advices and suggestions!

Feels like every photographer gotta know about aurora…
I love the green light
Really!
I don't know if every photographer, but for sure every human being should watch aurora in the life!
Nice information and good pictures!
I love the colour variations in the formation of aurora borealis and it's very interesting to know that it's visible by our retina.
Аmazing... Thank you for sharing...
Thank you!
🤩🌠
beautiful captured. it's on my todo list. need to travel to see it in person
your pictes is amazing
tks for sharing
I have waited years to take pictures of auroras!
can imagine, and you need the right time, isnt everytime that is visible,right?
if there are no clouds, it is visible with a very high probability. Problems is that in Lofoten it is often cloudy.
got it! tks
A beautiful conflagration of colours I can see. These green everywhere reminds me of Nature itself.
Your photos are beautiful.
Thank you!
