| Greeting from Tenerife! Thanks for sharing such a great picture

| Izana from time to time just to appreciate the sky and take some
| amateur pics with my Sony A7III. It is truly wonderful up there.

| seabass-labrax wrote:
| Sorry, but none of this makes any sense to me. First rare

| Having empathy is great, but it still _most_ likely that
| the availability of ultra-bright lamps is causing people
| to use them unnecessarily. There is an abundance of
| evidence that artificial light hurts natural ecosystems,
| not to mention inconveniencing astrophotographers, and I
| don 't think it's unreasonable to take a dim view of
| those who use bright lights in uninhabited environments
| like this.
| aa-jv wrote:
| What does the word "perhaps" mean to you?
|
| The example given was just an example - and in fact, an
| assumption cannot be made that the light-bearers were
| intentionally trying to interfere in a photo session.
|
| It is entirely unreasonable to think that strangers on a
| mountain will account for a random photography project in
| their thinking. So the blame game doesn't make any sense
| whatsoever.
|
| The onus of responsibility for having a clear shot,
| obviously lays with the photographer. Just because a
| photo is being taken, doesn't mean that others can't
| access the public space, too ..

| BurningFrog wrote:
| The simple, and rather obvious, answer is that you use
| lights at night to see where you're going!
|
| There is nothing wrong with that in general. If people are
| doing light sensitive things near me I'll of course adapt,
| if practical.
| globular-toast wrote:
| Yes and no. It's light pollution. It's this attitude that

| cars/motorbikes and way too bright headlights etc.
| Photography doesn't affect others, but light and other types
| of pollution do. People should think more carefully about how
| their super-important projects and errands will affect
| others.

| I think its more troubling to think that someones Very

|
| Whining about flashlights ruining your shot is one thing - not
| having compassion for someone who might be searching the
| mountain for a lost colleague, or any one of a number of other
| possible scenarios, is another thing entirely.
|
| Its quite psychopathic to not at least consider that there
| might have been a more noble purpose behind those flashlights
| than just "some random creep ruining my special shot".
|
| In this scenario, the onus of responsibility is on the
| photographer, not the other visitors, to ensure the sterility
| of their scene. Why didn't the author climb up there and talk
| to them, or coordinate at the visitors center, or some such
| effort - instead of just immediately jumping to hostile blame.

| Aren't you assuming that the author didn't reach out?
| aa-jv wrote:
| There's nothing in the article that indicates they reached

| assumption of entitlement to the mountain was being made,
| in spades.
| fumeux_fume wrote:
| Very troubling to think the author did not even consider that

| made. Actually quite psychopathic they didn't consider this
| at all.

| Now that I think of it, since they were shouting to turn

| to locate them. It would make sense that they came into
| their direction.

| for the volcanologists).
|
| I think the shelter's closed right now, so I guess in both
| cases it would probably be workers coming down.
|
| Seems like they decided last minute to hike up for doing the
| shooting, so I hope they got the night permit.

| It reminds me of one evening around the time of the recent

|
| Unfortunately, we weren't the only people with this idea. Half
| the town had descended on to this one meadow. It was quite
| comical seeing people awkwardly milling around who had clearly
| never been in a meadow in the dark before. Phone lights were on
| as well as fully lit screens etc. I think I've had better night
| vision during the day.
|
| One of them suddenly exclaimed, "is that it?!". It was, in
| fact, not "it", but rather the glow from the town in which we
| all lived.

| Fantastic shot!
|
| I was in Tenerife in November 2024. I did some basic
| astrophotography one night with my Pixel 6 phone and a steady
| hand.
|
| I managed to photograph M31, the Andromeda Galaxy for the very
| first time. It just appears as a faint oval smudge... but I was
| in awe.
|
| Locating it was a challenge (I was flipping between a 2D star
| chart and my photos) so I was very happy to finally capture it. A
| few days later I discovered the Stellarium app which makes
| locating things much easier.
