Full rainbow

[GeoffW]

This shot, showing Canberra, is taken from the top of a tower at the top of a mountain- the high viewpoint means that the bottom of the rainbow is not hidden behind the horizon.

That's beautiful! (And hopefully not criminalized or photoshopped)

[StuartR]

It's hard to believe that is genuine, but if it is then I am awestruck

Impressive. Do you know the altitude of the top of the tower on top of the mountain? I knew it was possible to see full circle rainbows from a plane so I guess quite high.

Meanwhile here, it's just raining with no chance of any sunshine.

The mountain isn't that big. Its elevation is 812m, above Canberra which is 577m; the viewing platform is about 60m height. So it's nearly 300m (984 feet) above the city in the picture.

I've been following the guy (Ari Rex) on FB for a while, he's a wonderful night sky photographer. While he uses Photoshop to stitch photos and to bring out the best in an image, and is quite open about what he does when he does so, he doesn't say that he's done so this time.

Today I witnessed the most beautiful thing i have ever seen in Canberra. This is the second time I have seen a full circle rainbow, the first time happened flying over Strahan Tasmania on a single engine Cesna plane. This time I went to Telstra tower to photograph the crazy storm that passed this afternoon, after the storm passed the tower, the beautiful rays of sun started to appear as the sun was setting behind me. I couldn’t believe my eyes when I saw the rich circle of . You can see the shade of the tower right through it .
It will take me a while to find the right tittle for this image .

A truly great shot.
I too have seen full-circles, but always from a plane; never from "the ground", albeit an elevated position on a ground construction.

I am very tempted to suggest chromatic aberration of the lens, in which case the correct "tittle" would be misattribution...

That's not chromatic aberration.

OK, I'm not a photographer! What is the correct name for that lens aberration then?!

[GeoffW]

Full circle rainbows are possible - just Google them. The observer needs to be at a high vantage point - usually they're seen from an airplane.

In Canberra, the conditions were just right for this photographer. The cold front system had just passed over Canberra very late in the afternoon - I was watching it because there were reports that it could have been a hailstorm. This photographer was presumably on the mountain to get lightning photos. The picture being taken is facing east, with the setting sun directly behind (hence the lit up city buildings). The chromatic whatever is a phenomenon which more typically occurs when the camera is facing a strong source of light, rather than behind.

That is a lovely image.

If the angle required for a rainbow to be visible is 42° between the sunlight and the reflected sunlight, the sun was high in the sky and the camera was a high altitude then that would be possible.

There is such a thing as chromatic aberration but it does not create rainbows like in this image, It's a much more subtle effect see here:

https://en.wikipedia.org/wiki/Chromatic_aberration

What you might be thinking of is 'lens flare' but that doesn't create rainbows like this either, see here:

Does this help?

[HansV]

Another impressive shot!

[GeoffW]

I don't have the talent to post shots like other Lounge members have been posting, so I have to post other people's shots.

...just won...

Me, jealous?

Ken

[ChrisGreaves]

It has just won an international photography award

And so it should.
Far be it from me to include the word "Photoshop" (he typed in a fit of jealousy), but how is it that the steel antenna tower is not being hit by lightning?

P.S. Yes, the image has been shoved straight into the wallpaper bin!

It looks as if all the lightning strikes (at the time.of the picture) were beyond the tower, possibly well behind. Some of the strikes are beyond another mountain, which is quite a distance away.

A pity his geography isn't up to his photography however.

It passed the city from West to East over the black mountains and continued towards Brindabella mountains.

It's Black Mountain, there's only one.

And the Brindabellas (Brindabella Ranges, more properly) are well to the west of Black Mountain.

A striking shot to say the least!

Great Observations Geoff! I hadn't looked that closely. There are indeed five lightning strikes behind the third mountain peak in from the left!

A pity his geography isn't up to his photography however.

This I don't really mind; I am not the pedant you all might think I am, and still cringe in horror when I remember my non-stop series of faux pas in Paris 40 years ago. My feet went so far into my mouth that I still walk with a pronounced limp.

And the Brindabellas (Brindabella Ranges, more properly) are well to the west of Black Mountain.

I can use Google maps like the best of us.

Geoff, Please don't spend more than a minute on this, but if you know your way around NE Canberra enough, can you find a street-view that shows a scene similar to the one in the photo? (Well, OK, obviously I can't use Google maps like the best of us.)
