Snowdonia seen from Howth, Dublin

I realized last night that my previous post was incorrect - the trig is explained here (2D)

The TL/DR is Snowdon is approximately 1000m high (1km) and the earth radius is 6350km, and the distance you could see from 1km high is roughly squrt(2*6350*1)km = 113km.

Since the distance in the photo is ~140km and you can clearly see a lot more than just the peak of Snowdon there must have been some interesting atmospheric refraction effect to make the photo possible.

Ah, but she might have said whales...

No definitely "Wales". She was responding (from home) to my daughter sending her the picture I posted here.

We see the Isle of Wight from Brighton fairly regularly. It's 40-50 miles away, something like that, and we can see the hills on the east coast, above Bembridge, which isn't exactly mountainous. This can be seen from the top of my road, so around 50-100m above sea level. This would suggest seeing mountains at 70 miles would be very possible.

Here's a photo, not mine, but gives you an idea. The pier is worthing pier, which is around 10 miles up the coast:

I think the horizon at the base of Snowdon is about the 200 - 250m level looking at the Rhydd Du ridge for comparison

I dunno why, but that looks a lot like New Zealand to me.

She might have been from Walsall and needed a new whale for her bike, because the old one didn't have no spowks left in it.

I've not been but I've seen similar photos taken in NZ. Painted houses, shallow pitched roofs, and a view across a bay to snowy mountains, it's a photog's favourite. Same thing happens in Norway, view over a village over a fjord to snowy mountains opposite. All those fjords...I won an award for Norway, you know.

Now that would be a mirage and a half...

"On clear days, the Wicklow Mountains can be seen, with Dublin city below. Slieve Donard, an 852 metre peak in Northern Ireland may also be visible. Quite frequently, Snowdon in Snowdonia National Park in Wales can also be seen."

...the chap who took the photo is a professional.

Not that it matters but he isn't: "...Niall, who is considering doing photography and videography professionally..."

"I took the photo just using my normal camera (Panasonix dmc-tz100), zoomed right in so I could see Snowdonia more clearly and used a filter just for more clarity,” Niall said."

The Panasonic has a 250mm Leica zoom: https://www.wexphotovideo.com/panas...Ix9_fQICFhLhIcl8ModsAzCM6xycZqZBoCUP0QAvD_BwE

Hmm.

I was brought up to believe that on a really clear day you can see the Urals from the Hawthorns. I never did though.

Was that Mr and Mrs Ural in Dudley?

 

[Seeker_UK]

I think they meant to type 'Urinals' - bloody autocorrect.

Hmm indeed.

Disregarding the authenticity discussion this "photo" is illegal. The photographer lives in Portmarnock and illegally travelled outside the 5km limit for non-essential travel here in Ireland. I will write to my local TD (MP) and seek the usual 100 euro fine for the photographer. I feel this is my civic duty.

If he is a professional photographer, could be he was working?

I direct you upthread: he ain't a Pro.

Ah ha, missed that.

This thread seems to work nicely as a metaphor for the dangers of the internet, and indeed, life. What to believe and when to believe it.

I posted the picture after my son, who lives just up the road from Howth, sent it on our family Signal group. He hadn't been sure it was real at first, but with his partner, who was born and grew up locally, did a few cursory online checks, and found that the story was on a few local media sites and that the photographer was "known", in some cases said to be professional. He was satisfied enough to share it with us, and knowing my son, I was happy to post it here.

As we have since seen, not all that information turns out to be quite 100% accurate, especially regarding the status of the photographer, though the key point, that it's a real photo of a real phenomenon, does seem to be true.

We all need to be on our guard, I suppose, but it's tricky.

Anyway. It's a damn good photo, and if I'd taken it, I'd have been bloody chuffed !
