Classic Jack White

[Obviousman]

And in classic Jack White fashion, when asked to prove his assertions he fails to respond. No doubt citing the totally uncivilized behaviour and attacks.... like someone actually asking him to support his claims....

Here's a question...
If lens flare doesn't occur in an atmosphere, why is it that Microsoft has included this visual effect in the last two versions of Flight Simulator??
Hmmmm....

[Jason]

Lens flare cannot occur in an atmosphere? Why would we even have the term "lens flare" then?

[BertL]

No, no, no, you're getting it wrong. Lens flare cannot occur outside an atmosphere, because there's no air outside the atmosphere.

[Jason]

That doesn't make any more sense, but okay.

Please see this page for a very good definition of what lens flare is and how it happens:

www.cambridgeincolour.com/tutorials/lens-flare.htm

Lens flare is caused by non-image light which does not pass (refract) directly along its intended path, but instead reflects internally on lens elements any number of times (back and forth) before finally reaching the film or digital sensor.

Lens flare can - and obviously does - occur regardless of whether you are in an atmosphere or vacuum.

I never said it made sense. ;D

Sounds like a Moonman quote to me.

I guess he's getting lens flares confused with "sun dogs" or such phenomena. If that is the case, then he really has no business pretending to be an expert in anything.

Just to confirm - presence of an atmosphere is NOT required for "lens flare" to occur. For starters, we have many Apollo photos which show lens flare. Here's an example:-



And a non-Apollo example (Gemini footage from LEO):-

And an example taken from Hubble



All three images above Earth's atmosphere, all three show lens flare.

You do know that any NASA photo wouldn't be credible, don;t you?

I figured this thread would be the best place for this topic since it concerns one of White’s assertions (as well as his lapdog, straydog.)

While watching the Missouri/Kansas State game (Go Mizzou!) this weekend I noticed something that I’ve never paid attention to before. I guess I’ve been reading these threads too much and they are spilling over into my daily life!

Missouri has a black helmet that is nice and shiny at the beginning of the game. No turf marks, no fingerprints from other players, no smudges, etc. The sun was nice and bright that day and you could see a very nice reflection of it shown on the helmet similar to a nice clean visor in space or on the moon; very round with very noticeable spikes. As the game wore on and the helmet gets all of the afore mentioned marks on it the reflection changed quite a bit. The thing that I really noticed was during a close-up of any given helmet. (being in HD really helped) Watching in slow motion as the player turned his head and the reflection of the sun moved across the black helmet it changed back and forth from very round and sharp to very oddly shaped and fuzzy. Part of the helmet was still nice and shiny while others parts were full of smudges, etc. Smudges on the helmet do affect the way the reflection appears just the way a dirty, smudge covered visor on the moon will affect the reflection of the sun. The visors worn by the shuttle astronauts do not get near as dirty since their gloves are not covered in lunar regolith making the visor much cleaner and producing a nice sharp reflection.

I saw with my own eyes how the cleanliness of the visor/helmet is a key factor in producing reflections of the sun that look like “barn doors” and other such nonsense.

As you guys have said numerous times, people like White and his puppy reach a conclusion and then try to find evidence to support it rather than the other way around. If the evidence doesn’t fit the conclusion, dismiss it out of hand and attack anyone who dares show otherwise.

This Wildcat disagrees with your football loyalty, but is compelled to agree with your analysis of helmet reflections.
