New photo technique reveals rocket plumes
Anyone who has witnessed the launch of the space shuttles can't help being impressed by the blinding brilliance of the craft's rocket plumes. The three liquid-fueled main engines and the two solid fuel boosters produce a flame that is almost painfully bright. My reaction every time is that the thing is too ferocious for humans to ride. And yet they do.
And as many times as I've watched launches on TV, the spectacle never comes close to the experience of being there. The flame is muted on the TV screen, just like the thunderous, crackling roar.
The exhaust plume gets washed out in still photos, too, becoming flat and featureless.
But a team of NASA researchers has managed to put together a composite photo technique that can now reveal the contours and details of a rocket plume. Instead of a flat yellow or white, the plume becomes a turbulent storm with ropes of flame and smoke. They tried it out on the final shuttle launch that sent Atlantis into space last month.
Here is a comparison of the new technique (right) and a standard image. Pretty cool. Here's more on how they did it.

Nice,
Looks like they are getting together some nice photos detailing our decline in Space.
Hard to not be sarcastic when discussing the lack of space program we have now.

HDR isn't exactly a new technique. But it is the technique du jour for amateur photographers who read about it in their photo magazines and overdo it to produce cartoon-like images like the one of the shuttle. While it's cool to see the flames in detail, the photo as a whole looks fake and over-processed.
Also, it would be nice to see the brilliant colors produced by the rockets. B&W doesn't do it justice.
