Amazing footage of Perseverance landing on Mars

Insanely magical.

The real footage in this video was captured by several cameras that are part of the rover’s entry, descent, and landing suite. The views include a camera looking down from the spacecraft’s descent stage (a kind of rocket-powered jet pack that helps fly the rover to its landing site), a camera on the rover looking up at the descent stage, a camera on the top of the aeroshell (a capsule protecting the rover) looking up at that parachute, and a camera on the bottom of the rover looking down at the Martian surface.

If that’s up your alley, check out this 4K video showing images of the red planet (captured earlier):

Per Laughing Squid,

Elderfox Studios took photographic footage taken by various Mars space rovers and compiled them into an absolutely astonishing 4K rendered video that reveals the surface of Mars. The original photos used in this short but stunning documentary were from NASAJPL-CaltechMSSSCornell University and ASU.

Great space photography o' the day

  • The Big Picture features some excellent images of man on the Moon–both past and future.  (I’ve gotta get one of those ATHLETE vehicles for a future Death Valley outing.)  They also feature recent volcanic activity.
  • The Hubble recently spotted–er, spied–Jupiter’s Great Red Spot eating the "Baby Red Spot."  More beautiful high-res shots of Jupiter & its moons–including amazing shots of volcanoes in action–are here.

Saturday Science: Great photos of Earth, Mars, & beyond

Boston.com’s new feature The Big Picture dispenses with traditional peanut-sized Web photos and showcases great images in the news.  Site designer/developer/writer/photo editor Alan Taylor talks about his brainchild and how it came to be. [Via]  Lately they’ve been harvesting the best photos that billions of tax dollars can buy:

 

  • The Sky, From Above features gorgeous shots of the Space Shuttle at liftoff, as well as of thunderstorms over the American Midwest and more.  [Via]
  • In Martian Skies, you can view panoramas from Mars and watch dust devils skittering across the Martian landscape.
  • The site also features a retrospective of some of the great images sent back home by the Cassini space probe over the past four years. [Via]

On related notes, apparently the Mars Phoenix rover is broadcasting via Twitter.  Also, NASA’s new space suit design looks rather trim & buff.  I kind of miss the human Jiffy Pop bag look, though.

Counting chickens in Africa, via Photoshop

A few years ago I heard from a researcher at DuPont who was, as I recall, using Photoshop’s Histogram palette & other tools to analyze samples of Kevlar and other materials.  Later I visited the Johnson Space Flight Center and talked to a team about using Photoshop’s Ruler Tool to assess possible cracks in space shuttle heat shields photographed during flight.  No matter what you think a given feature is designed to do, customers will always find interesting ways to push it farther.

 

In that vein, Chris Ing gets crafty on JacksofScience.com, using the new analysis tools in PS CS3 Extended to do everything from estimating chicken density in Africa* (by analyzing the "integrated density" of various regions of an info graphic) to calculating the height of Kirsten Dunst (studiously cross-checked against something called Chickipedia–and no, I’m not feigning ignorance).  Should you find yourself "interested in comparing the circularity of your head to that of a friend," you’ve got a kindred spirit.

* Sorry, the pre-/post-hatched counting enhancement will have to wait for a future release. (We’ll sic Chris on it.) We’ve heard somewhere that it’s an important distinction…

Air cannons & soda fountains

Okay, so their connection to this blog is tenuous at best, but these semi-science-y vids are too fun not to share:

  • A while back I mentioned the 150-T-shirt Human Flipbook that Colle+McVoy created for sandwich chain Erbert & Gerbert.  Now they’ve returned with
    CandleCannon.com.  Gotta love the insane whooping of geeks celebrating. [Via Dustin Black]
  • Some 1,500 Belgian kids did their best Blue Man impression, launching sticky geysers of foam as they attempted to create the world’s largest Diet Coke/Mentos explosion.  I can’t find a video of this stunt, but these guys were apparently trying to outdo these folks in Cincinnati.

Science drops: Tumbling hippies, Chinese cannons, & more

Okay, I’m getting a little far afield of scientific imaging per se, but I found the following interesting & thought you might as well.

  • Oh man–tumbling hippies + Jabberwocky + amino acids: this 1971 MIT video has it all.  When that hoodling organ sountrack kicks in, you know it’s gonna be good. (Skip ahead 3:30 or so to the dancing.) [Via]
  • Hmm–I wonder whether these come in “Ps” or “Ai”: periodic table rings. [Via Jeffrey Warnock]  (Of course, a more committed geek would go with knuckle tattoos–the arm already having been done.)
  • The Chinese government is apparently trying to control the weather at the Olympics, literally shooting clouds out of the sky.  Seriously.
  • Lunar images & infographics:
  • I’m not sure that it constitutes scientific imaging, but Wikipedia hosts a beautiful column of fire.  Talk about an awesome blossom.

Sputnik via Flash, the wobbly moon, & more

Spacing out this weekend:

  • Commemorating the 50th anniversary of the launch of Sputnik, the NY Times offers a nice, brief interactive tour of that first human-made spacecraft, as well as a timeline of space exploration.
  • Evidently the moon wobbles during a lunar cycle, as this timelapse animation shows. [Via]
  • Speaking of our satellite, Adobe’s resident Academy Award-winner Mike Kanfer enthusiastically recommends the documentary In the Shadow of the Moon.  I get chills watching the trailer.
  • What if we had no moon?  In Astrobiology Magazine scientist Bernard Foing charts the moon’s influences on the history of earth, from the formation of solid land to the development of our eyes. [Via]
  • CNET shows images from a Japanese space probe in lunar orbit. They report, “China is expected to launch its first lunar exploration satellite later this month; India has plans for a moon launch in April 2008; the next U.S. moon mission is slated for 2008; and Russia could be flying private citizens around the moon and back as early as 2009.”
  • Meanwhile Google is offering a $30 million prize to a private team that can land a robot on the moon.
  • And speaking of Google, hide your crops, Cheech: law enforcement uses Google Earth.
  • Fast networking technology has enabled researchers to assemble an Earth-sized telescope. [Via]
  • Nerding out on Wikipedia, I happened across a cool shot of a Delta IV rocket lift-off.

Adobe puts 3D insect eyes on your camera

“Why,” I wondered for a long time, “is a wild-haired Eastern European guy walking around our floor carrying a medium-format camera & a hot glue gun?”  The answer, I discovered, is that Adobe research scientist Todor Georgiev* has been working on algorithms for use with a plenoptic camera & was motivated to build his own lenticular lens array.

So, what does any of that mean?  The goal is to let cameras capture a moment in time from multiple slightly different perspectives.  The resulting image (a series of smaller images, actually) might then enable the photographer to change the focal distance of the photo after the fact, or to use depth information to aid in selecting & editing objects.

News.com has more info & images, and I think the potential comes through best in Audioblog.fr’s video of Adobe VP Dave Story showing off the lens.  Gizmodo writes, “It’s a way-cool demo, but it might be a while before you see such a fancy lens on everyday cameras. But a focus brush in Photoshop? Whoa. Sign us up.” [Via Cari Gushiken]

*Okay, his hair seems to be less wild these days, but Todor still kicks out “light reading” like this (PDF). I think I left my copy at the beach.

Undersea photography, ancient anatomy, & more

Lots of cool scientific & technical imaging has popped up recently:

Fighter jets, galaxies, & infrared squirrels

From the world of scientific & technical imaging:

  • "You come across the body of a tramp, which in itself is not so disturbing. Until it is turned over to reveal…. ANTS! ANTS! ANTS!"  Er, sorry, I digress.  Joe Lencioni has captured some great macro shots of yellow ants (acanthomyops to their friends).
  • Seed Magazine features a fascinating video tour of scientific visualizations–from Benoît Mandelbrot’s early fractals to an atomic simulation that required six months of supercomputer rendering to depict 20 nanoseconds’ worth of motion.  (Oh, and the closing soundtrack is from Dub Side of the Moon.) [Via]
  • News.com reports on a cool technique for astrophotography–taking up to 20 images per second, then using computer image processing to sift & combine the sharpest results, compensating for degradation caused by Earth’s atmosphere.  Details & before/after images are on the Lucky Imaging site.
  • NASA’s Galaxy Evolution Explorer (GALEX) telescope has captures pix of a star with a comet’s tail. [Via]
  • Who knew that squirrels have infrared-emitting tails, useful for confusing rattlesnakes?  This is kind of thing you learn when grad students get to wander around with expensive camera gear. [Via]
  • A Russian air show produced a terrific image of an Su-27 dropping flares.  (Who needs safety regulations?)
  • Inspire Underground hosts a photo essay on prepping the Space Shuttle for launch. [Via]  Post lift-off, the Shuttle crew captured some lovely shots. [Via]

World's first terapixel image, online via Flash

Medical imaging company Aperio has created what it’s calling "the world’s first terapixel image"–i.e. an image containing more than one trillion pixels. The image itself, depicting a breast cancer scan*, is a 1,095,630 x 939,495 pixel whopper that tips the scales at 2875.94GB.  More info is in the press release.

From a Photoshop/Adobe perspective, it’s cool to see this image displayed via the Flash Player, using the same Zoomify technology that’s in Photoshop CS3.  The folks at Aperio write,

You may be interested to know Aperio has implemented BigTIFF – support for TIFF files larger than 4GB.  After linking the new version of libtiff into our ImageServer, we were able to use the Zoomify viewer with no changes at all.  Pretty impressive. By way of demonstration we’ve made the world’s first terapixel image, and it can be viewed right in a standard web browser with the Zoomify technology."

[For more Zoomify hugeness, check out the 8.6 gigapixel fresco mentioned previously.]

*Not the most asethetically compelling image–unless, I suppose, it proves that one doesn’t have breast cancer

Digital imaging goes to court

CNET reported recently on a court case that involved image authentication software as well as human experts, both seeking to distinguish unretouched photographs from those created or altered using digital tools.  After disallowing the software, written by Hany Farid & his team at Dartmouth, the judge ultimately disallowed a human witness, ruling that neither one could adequately distinguish between real & synthetic images.  The story includes some short excerpts from the judge’s rulings, offering some insight into the legal issues at play (e.g. "Protected speech"–manmade imagery–"does not become unprotected merely because it resembles the latter"–illegal pornography, etc.).

As I’ve mentioned previously, Adobe has been collaborating with Dr. Farid & his team for a few years, so we wanted to know his take on the ruling.  He replied,

The news story didn’t quite get it right. Our program correctly classifies about 70% of photographic images while correctly classifying 99.5% of computer-generated images. That is, an error rate of 0.5%. We configured the classifier in this way so as to give the benefit of the doubt to the defendant. The prosecutor decided not to use our testimony because of other reasons, not because of a high error rate.

The defense argues that the lay person cannot tell the difference between photographic and CG images. Following this ruling by Gertner, we performed a study to see just how well human subjects are at distinguishing. They turn out to be surprisingly good.  Here is a short abstract describing our results. [Observers correctly classified 83% of the photographic images and 82% of the CG images.]

Elsewhere in the world of "Fauxtography" and image authenticity:

  • In the wake of last summer’s digital manipulation blow-up, Reuters has posted guidelines on what is–and is not–acceptable to do to an image in Photoshop. [Via]
  • Calling it "’The Most Culturally Significant Feature’ of Canon’s new 1D MkIII," Micah Marty heralds "the embedding of inviolable GPS coordinates into ‘data-verifiable’ raw files."
  • Sort of the Ur-Photoshop: This page depicts disappearing commissars and the like from Russia, documenting the Soviet government’s notorious practice or doctoring photos to remove those who’d fallen from favor. [Via]
  • These practices know no borders, as apparently evidenced by a current Iranian controversy, complete with Flash demo. [Via Tom Hogarty]
  • Of course, if you really want to fake people out, just take a half-naked photo of yourself, mail it to the newspaper, and tell them that it’s a Gucci ad. Seems to work like a charm. [Via]

Photographing Saturn; Rocking Jupiter

NASA’s JPL has surveyed the public & posted the favorite photos of Saturn taken by the Cassini-Huygens mission. You can see more from their collection here. [Via]  And if you’d like to try your own hand at photographing the planet, see Space.com’s advice on how to Capture the Lord of the Rings (with a little help from Photoshop).

The space connection keeps reminding me of a drive-by beat-down administered to the band Train (the guys who brought you "Drops of Jupiter," and who have apparently sold four million albums–to whom, no one knows): "Watching her cry, I knew Benchley had hit bottom. I had reached the mythical state of total anti-rock, which I call ‘Train,’ after the band. When the head of every drum is torn, and all guitars out of tune, when the microphone melts in your hand, that’s Train, and I was in Train all the way up to my drops of Jupiter."

Genetic mutation named after Photoshop

Psst–read any good overviews of the Functions of the Nonsense-Mediated mRNA Decay Pathway in Drosophila Development lately?  (Yeah, who hasn’t, I know…)  I mention it because a mutant phenotype (specifically, a fluorescent protein in fruit flies) has now been nicknamed "photoshop" by researchers Mark Metzstein & Mark Krasnow.  ["Shouldn’t that be Adobe® Photoshop® software?" murmur a dozen voices in Adobe Legal. 😉 ]  They write, "We named this the ‘photoshop’ phenotype because it increased visualization of clones like that achieved by digital enhancement with Photoshop software (Adobe, http://www.adobe.com)."  [Ah, says Legal.]  As a highly nonsense-mediated individual, I say very cool, guys!

Chemical Romance, Daahk Mattah, & More

  • Apple.com features the work of Harvard/MIT researcher Felice Frankel, showing how she uses Photoshop to depict the beauty in a chemical reaction (see animation).
  • In their continuing quest to blow my little Arts & Legos mind, scientists have unveiled a 3D map of dark matter (see larger image). [Via]  I had to smile on this one, remembering that the Photoshop CS1 was codenamed "Dark Matter."  In one of the early go/no go meetings, Adobe CEO Bruce Chizen–who is from Brooklyn & very much has the accent to prove it–joked, "I’d really like to thank you for picking a name with two ‘R’s in it.  Daahk Mattah…"
  • It’s not imaging-related, but the Celestron Sky Scout has been a huge hit at the Nack compound.  (I have it on good authority that I was recently hitched, but you wouldn’t know it on these cold, clear nights: la esposa keeps bailing on me to learn about the heavens courtesy of the Sky Scout!)

Decoding scrambled pixels

Removing data from a digital file is sometimes easier said than done. Redacting PDFs has sometimes proven tricky (something the Acrobat team has worked to address), and now a research report notes methods for unscrambling numbers or text that have been obscured via simple Photoshop tricks. [Via]

I asked a few Photoshop engieneers for comments & got some useful nuggets:

  • Gregg Wilensky says, "The ability to recover text that is blurred is limited by the amount of
    noise in the image (and knowledge of the blurring function). So, adding
    a bunch of noise to the image is better, but still not foolproof. I
    would suggest completely replacing the text with noise and blurring that
    (for aesthetics)."
  • Jerry Harris notes, "Having a known set of limited targets, OCR numbers in his example, makes the
    reconstruction task a bit more realistic in terms of useful results than
    most."
  • And Todor Georgiev writes, "Using a known set of blur kernels (those in Photoshop!),
    and a known set of targets, limits the set of possible outcomes
    and makes this technique work. But slightly change lighting
    and/or use custom blur filter, and your data is safe."

Atmospheric photography

  • Marc Pawliger passed along this gallery from PhotoAstronomique.net, containing some interesting time lapse stuff.  Shots like this one make me remember how much I have yet to learn about my camera.  As the text is in French, I can’t read much of it, but I think "Arc de brume" sounds great. [Update: Here’s the site in English.]
  • Seeking atmosphere of a different kind, Nicole Bengiveno has captured some beautiful impressions around NYC.  (The music may or may not be your cup of tea; I preferred to nuke it and focus just on the visuals.) [Via]

More animals in the womb, plus a space shot

  • A number of folks have commented on the amazing images of animals in the womb, so I’m following up with some more info I’ve found.  In support of the special program airing tonight on its namesake channel (9PM PST), National Geographic has posted some great online resources, including a video preview, an interactive timeline, and more photos. The show is scheduled to air tomorrow night as well.
  • This NYT story about last night’s launch of the shuttle Discovery includes a couple of really dramatic photos. NASA.gov has another, as well as an image of the shuttle’s rotating service structure at night. (Seeing that shot, I can almost smell the airplane glue & feel the Xacto cuts as I struggled to build a model version years ago. That effort did not end well…) And here’s a video of the launch.

Animals photographed in the womb, & more

More stellar imagery (literally)

  • The Photoshop team got a treat today when astro photographer David Malin paid us a visit.  David shared a selection of his work and techniques with the team, and put in some good requests (some of which we are delighted to be addressing).  His site features a wealth of photos, including 50 Favourite Images from the Anglo-Australian Observatory. 
  • Along similar lines, I recently discovered a collection of 100 Great Images from the Hubble, as well as this stunner.  And speaking of the famous telescope, in response to the news that it’s been decided to keep the Hubble flying (yeah!), the NYT has posted a short essay on the history of "NASA’s Comeback Kid." As always, if you want to open the raw imagery from the Hubble directly in Photoshop, check out the free FITS Liberator plug-in.
  • My friend Phil Metschan, an art director at ILM, has created some concept art for his rocket-science brother’s proposed space flight technology. (More pix are on pp. 41-45 of the PDF.)  It’s kind of funny for me to think that just a few years ago Phil and I were in NYC, building the Gucci site in Flash.  Seems a world away now…

[At the other end of the size spectrum, David has created some beautiful micrographs from very tiny subjects (crystals, etc.).  The images remind me a bit of Mac pioneer Bill Atkinson‘s ridiculously lovely coffee table book Within the Stone.]

Drawing tools: Rat brains, willows, and Director

  • Mikons is "a new form of self-expression that connects people through visual symbols (personal tags)," and the site creators call their Mikon Machine (created using Director) "the most advanced drawing tool of its kind available on the Internet."
    They plan to add color, text input, a product builder, and a store to enable artists to sell their designs.
  • Cumulate Draw offers a some similar capabilities but is done by leveraging the scripting engines built into modern Web browsers [Via]
  • If having humans in the loop gets you down, why not try a little tree art? British artist Tim Knowles attaches pens to the branches of various trees, letting them draw whatever the wind dictates.  I’m having trouble getting the photos to appear in my browser, but here’s a link in case you have more luck.
  • Not out there enough for you?  Okay, how about 50,000 rat neurons in a petri dish driving a robot arm in Australia, translating neural activity into drawings? Read all about it.

Beautiful scientific imagery

  • The Cassini space probe has produced a stunning image of Saturn and its rings.  The panoramic view was created by combining a total of 165 images taken by the Cassini wide-angle camera over nearly three hours. Color in the view was created by digitally compositing ultraviolet, infrared and clear filter images and was then adjusted to resemble natural color.  Check it out in high res.  [Via]
  • Elsewhere in space, Wikipedia features a great shot of a sunset on Mars (in no way to be confused with Breakfast on Pluto).   And in case you missed it earlier, check out that shot of the space shuttle in front of the sun.  As a celebutante would say, "That hot."
  • Slightly closer to Earth, the NYT has a story and slide show of backyard rocket builders in the desert. Their creations–some able to fly to 94,000 feet–are a bit more impressive than my old DIY constructions (paper towel tube, "D" rocket engine, and as many Black Cats as I could cram in). Yeah, but mine blowed up real good.
  • And much, much closer to earth, the NYT shows the entomological images of Dr. Thomas Eisner. This bombardier beetle is out of hand, though the shell constructions seem a little close to the rogue taxidermy of MART.

Mona's from Mars, Photoshop's from Venus

Photoshop’s use in the sciences has been getting some good press lately:

(See the Science & Tech category for more stories.)

Photoshop & the Dead Sea Scrolls

Ah–here’s a great example of a non-traditional use of Photoshop that I’ve been wanting to share for a while. Researchers at USC’s West Semitic Research Project have been using Photoshop to aid in analyzing the Dead Sea Scrolls and other historic texts. Dr. Bruce Zuckerman, director of the WSRP, writes, “Adobe Photoshop CS2 is the single most important enabler in the WSRP’s work. It is pivotal to our ability to unlock the history of the ancient past.” We’ve put together a 4-page article (PDF) that talks more about the work:

Frequently, Photoshop CS2 is used to combine parchment or papyrus fragments of texts that are often physically separated in different museums and libraries in what amounts to digital jigsaw puzzles. Some writing is so tiny that researchers use a fiber-optic “light brush” to direct a very narrow beam of light onto a small area. In such cases, Photoshop CS2 allows scholars to combine images to build composites out of the smaller images. Some writing cannot be seen at all because the background is too dark or the ink itself is too faded. In this case, researchers use infrared and ultraviolet imaging to reclaim the ink traces. Because infrared and ultraviolet images sometimes hide as well as reveal data, scholars use Photoshop CS2 to combine various images in order to have all the visual information available for viewing.

  • John Dowdell mentions Adobe’s growing focus on imaging science and outreach to scientists–for example, the image authentication work on which Adobe’s been collaborating with Dr. Hani Farid & his team.

Photoshop & bugs (the exoskeletal kind)

Now that we’ve squashed some bugs in Photoshop CS2*, we can look at an instance of the tools being used in conjunction with actual insects. Microscopy UK talks about photographing slide mounts using a combination of digital SLRs, microscope, and slide scanner. The Photoshop content here is limited, so I’m passing it along as much for the great high-res imagery as anything. [Tangentially related: Berkeley scientists have been inspired by insect vision to create new camera lens designs.]
* Speaking of Photoshop and bugs (the other, bad kind), there’s a Photoshop Top Issues RSS feed as well as a dedicated product support page. If you see something going haywire, please let us know (and send us your feature ideas, too). We probably won’t respond to each report directly, but we do read them all, and we use the info to guide product planning. Thanks.

Scientific illustration in Photoshop

Keeping the science theme going, I’ve gathered some examples of Photoshop’s use in scientific illustration:

By the way, on the subject of scientific illustration, I recently discovered Albertus Seba’s Cabinet of Natural Curiosities, an amazing collection of 18th-century illustrations of animals, plants and insects. And if that’s up your alley, see also Dream Anatomy, a collection of antique anatomical renderings drawn from the National Library of Medicine. [Via] Or for a more modern spin, see the adorable (?) squirting stomachs of I Heart Guts [Via].
[PS–6 minutes after I posted this, a copy of Cabinet of Natural Curiosities showed up at my door. Score!]

Photoshop & Rocket Scientists

News of astronauts firing an empty space suit into orbit (seems like such a dude thing to do, doesn’t it? “Heh heh–when it hits the atmosphere it’ll blow up real good, heh heh”) got me thinking about Photoshop’s role in space imaging.
Data captured by the Hubble Space Telescope & other high-powered telescopes are stored in the FITS format, as packets that need to be re-assembled for use on computers. To make the public-domain data widely available (beyond the 900 or so pro astronomers in the world), a team from the European Southern Observatory, ESA, and NASA created the FITS Liberator plug-in for Photoshop. NASA’s Hubble Source features an article on creating your own color Hubble images using the tools together. As of version 1.6.05 FITS Liberator had some 50,000 users, and version 2.0 (released in August) takes advantage of new 32-bit HDR imaging support in Photoshop CS2.
Check out the image gallery, and drop us a line if you try out FITS Liberator with Photoshop. We’d love to hear your story & see your images.

Image authenticity & Photoshop

The topic of verifying image authenticity, covered well in the NY Times article It May Look Authentic; Here’s How To Tell It Isn’t, continues to draw considerable attention. Photoshop of course gets pressed into duty on the falsification side, so Adobe staff have been fielding a number of press inquiries on this subject.
What may be less obvious is Adobe’s interest in the other side of the coin: image analysis & authentication. Last summer Dr. Hany Farid (mentioned in the Times article) spent his sabbatical from Dartmouth at Adobe, collaborating with the Advanced Technology Group on tools & techniques for detecting image manipulation. Photoshop is heavily used by a wide range of government & scientific bodies, aiding in everything from detecting forged checks (you’d be amazed what a few adjustment layers can reveal) to cleaning up satellite imagery to analyzing the Dead Sea Scrolls (more info on that soon). At the request of image retouchers who need to document their work, we added the Edit History Log, making it possible to store a textual log of edits done to an image (essential for reproducibility). Combined with the ability to embed raw files as Smart Objects, this feature makes it possible for a Photoshop document to contain essentially the negative, the print, and a printable record of edits performed.
For more on Dr. Farid’s research & tools, see his own site as well as this National Geographic article on detecting forged artwork. For more on Photoshop in scientific imaging, Adobe.com now details how scientific features have grown over the last few releases, alongside white papers on best practices.

Todor & Jeff's Image Science Hut: Coming Thursday

No, they don’t wear fezzes and matching shirts, but resident brainiacs Todor Georgiev and Jeff Chien have been behind some of the more eye-popping features in the last few releases of Photoshop, including the Healing Brush, Patch Tool, Match Color, Smart Sharpen, Reduce Noise, Perspective Crop, and Spot Healing Brush.
I mention this because Todor will be speaking at the next Silicon Valley ACM SIGGRAPH event, taking place on Thursday the 17th in Cupertino. For background, here’s a PDF on the kind of thing Todor will be discussing. My fellow product manager Ashley Manning will kick things off with a demo, and Jeff should be on hand as well. (Oh, and there will be schwag.)

Droppin' some science

Psst–hey buddy, seen any good kite-borne photos of Estonian peat bogs lately? You would if you checked out the winners in Science Magazine and the National Science Foundation’s Visualization Challenge [link via PhotoshopNews]. But if your tastes run more towards the secret life of the pea weevil (really!), check out the Visions of Science Photographic Awards. Winners include revealing images that were colored in Photoshop.
Photoshop wasn’t designed for scientific imaging per se, but we’re learning quite a bit about how it gets used in a broad range of applications. Last year I got to visit NASA’s Johnson Space Center. The team preparing the next shuttle flight requested better measurement tools that could aid in the analysis of the shuttle’s heat-resistant tiles. (They also mentioned a rumor that a copy of Photoshop has even found its way onto the International Space Station–evidently several astronauts are avid photographers–but I’ve never been quite able to confirm that.)
We’re working to build up info and resources on Photoshop in the sciences, as well as its uses in engineering and other disciplines. If you’re using Photoshop in these fields, and/or if you have ideas on how we should develop the app to suit your needs, please let us know. Post a comment, or drop us a line.
Thanks,
J.
PS–Apple’s scientific computing pages mention numerous uses of Photoshop, including the Visible Human Project.
PPS–Good luck to this group of 7th & 8th graders, who want to send film into orbit and then analyze the results in Photoshop.
