Is this supposed to be an accurate composite?
I don't like to suggest this, but it looks somewhat faked... Look at how the meteors are in-line with each other. That's not how a random distribution would look.

I believe the random motion between the meteors is minor compared to the collision speed between the Earth and the meteor/comet trail. Thats why they seem to travel across the sky like that. Lens distortion like fisheye also affect the image.
Does anyone have a suggestion on software for producing a composite meteor image? Stacking seems to wash them out.
Most of the meteors are in-line
with other meteors. There are four lines of meteors, three in a row, basically nose-to-tail.
And there are other meteors basically nose-to-tail. That has no relation to collision speed or lens distortion.

(I'm not a photograph, so I ask)
Since catching many meteors requires time (at least a couple of minutes), why the sky didn't turn, making arc out of stars?
(not clear ? I'm french
I vote FAKE NEWS
Yes, to some extent, it is fake. And we should understand that some of this is accepted, even necessary practice.
Any such image, to attempt to represent what our eyes and brains would have seen, had we been sitting there for 2 full nights in a row, will have to be put together from a set of very different photographs. I think the astrophotographer who composed this did the following. First, as he describes in detail on his facebook at the "featured image" caption link, he collected 50 hours of work with 4 cameras to capture the meteor trails. Next, he must have obtained one or more foreground landscape images and one or more sky images. At very different exposures. Finally, he would have put it all together.
FLPhotocatcher has an interesting point. I would think, for faithfulness of the experience, the meteor trails should have been placed "where they were on the sky", when stitching together, but perhaps this was not totally accurately done. Of course, we could ask Makrem Larnaout at:
if one has a question about this. Having used 4 cameras to capture the meteors, some manual placement of the trails may have been necessary. I certainly do understand that APOD viewers, at least, would want this to be done with as little artistic license as possible. And I think it was astute of FLPhotoCatcher to have noticed the alignments.
