    Wow, that’s freaking amazing!
    It’s like a time machine

    I love it, that would be so helpful. I’m not sure if it would make it into Photoshop CS6 from the looks of it, it seems he had to pull a few levers to make each photo deblurring happen. Hopefully it will be easy when/if it comes out and not require too many settings or parameters.

    But definitely I WANT THIS ! Bravo Adobe.

  4. This is great. I can’t wait to use this on the Zapruder film and the Patterson/Gimlin Sasquatch footage. The results will be earthshaking! ( ;-)

    Thanks, Adobe!

    Holy Smokes ! ! !

    I sure hope it’s in CS 6, but from the hinting maybe it won’t be.

    @ Stéphane

    No, it is not real. The picture of Kevin Lynch was originally sharp. They then blurred it in Photoshop. Easy to undo. See:

    Let’s see them unblur a photo which came out of the camera already blurred.

    I want this SO bad. Unfortunately it’s not in the beta of Photoshop CS6 so I don’t even think it’ll be in the final version. We’ll have to wait till CS 6.5 or 7 probably, unless they release it as an update, but I’m afraid it’s too big news to just include it in an update.

  8. @ProDesignTools

    We just got an email back from Jue Wang (from Adobe Research and the presenter of the deblurring sneak peek), who explained the history of the images used in the demo…

    There’s no issue to speak of really – here’s what he wrote us:


    Hi, we have updated our recent blog post to include a statement on this. If you could point readers to this post that would be great.

    -Jue


    And that post addition says:


    UPDATE: For those who are curious – some additional background on the images used during the recent MAX demo of our “deblur” technology. The first two images we showed – the crowd scene and the image of the poster, were examples of motion blur from camera shake. The image of Kevin Lynch was synthetically blurred from a sharp image taken from the web. What do we mean by synthetic blur? A synthetic blur was created by extracting the camera shake information from another real blurry image and applying it to the Kevin Lynch image to create a realistic simulation. This kind of blur is created with our research tool. Because the camera shake data is real, it is much more complicated than anything we can simulate using Photoshop’s blur capabilities. When this new image was loaded as a JPEG into the deblur plug-in, the software has no idea it was synthetically generated. This is common practice in research and we used the Kevin example because we wanted it to be entertaining and relevant to the audience – Kevin being the star of the Adobe MAX conference!

    For more information and examples on the common practice of synthetic blurring being used as part of research in this area, check out:

    grail.cs.washington.edu/projects/mdf_deblurring/synth_results/

    cse.cuhk.edu.hk/~leojia/projects/robust_deblur/

    wisdom.weizmann.ac.il/~levina/papers/deconvLevinEtalCVPR09.pdf


    If you check out those links you’ll see this is pretty complex stuff, and the blurs are commonly done using both techniques in this type of research. Hope that helps.

    The problem is it was not presented as “We put this known, synthetic PSF onto this picture. Now we are undoing the known function.” It was presented as this is what we are working on, this is what you can expect in a future product. Customers will not be inputting a known blur on their pictures so they can buy photoshop to deblur it!

  10. Martin

    @ProDesignTools
    Sure. They just forgot to say that.

    Moreover, did they perhaps also avail themselves of the parameters used to create the blur in the first place? Calculating those parameters from the blurred image alone is non-trivial, and without them the deblurring is not possible.

    So it is not simply a case of using a manufactured image out of convenience or for the sake of starting from a lab-controlled type and amount of motion blur. Knowing the blur parameters in advance makes finding the inverse operation much easier also.

    that before + after comparison is amazing … thx for posting

  12. Martin

    @ProDesignTools
    I’ve never know a person to fabricate a story or misrepresent the truth as a means to cover up their honesty, integrity and innocence. I have always found that when people misrepresent the truth it is for other reasons.

    • Martin, they already gave the other reasons – for convenience, to have a MAX-related image going in that they could demo. Now agreed, they didn’t explain it well and some would argue it was poor judgment in the setting, even if it’s common practice in the broad research in this field.

      The net effect was overemphasis on that last image shown, which was up for only a moment for the sake of MAX connection – and distraction from the first two images (the plaza scene and the poster text) which were real-world examples of corrected motion blur from camera shake.

  13. Martin

    @ProDesignTools
    “Martin, they already gave the other reasons – for convenience, to have a MAX-related image going in that they could demo”

    But there is absolutely no problem with them using that image, no problem with synthetically blurring it, out of convenience or whatever. That is not the issue here. The issue is that they specifically stated to the contrary, that it was just a “random” image, and an originally “bad” photo at that – it had camera shake.

    My question is not “what compelled them to use that image” – like you say, they have explained that.

    No, my question is, “What compelled them to deliberately, unequivocally, misrepresent the truth about a critical aspect of the demo?”

    The truth comes naturally, it requires a reason to deliberately depart from the truth. What was that reason?

    • Obviously, because it was simpler/easier for the presenter to say that, and because it had greater impact. It wouldn’t work quite so well to say, “now here is a final photograph we got from MAX that we synthetically blurred by extracting the camera shake information from another real blurry image and applying it to create a realistic simulation”…

      But on the other hand, doing it the way he did for that last brief image created needless controversy and distraction versus if they’d just used real photos throughout. The first two real-world images were impressive enough by themselves without that last photo in the final seconds.

      Bottom line, as previously discussed, the last example wasn’t presented as best it could and arguably shouldn’t have been included, or would have better been replaced with another naturally-blurred image.

  14. Martin

    So do these guys a favour – post up a genuine camera-shake image of your own making on your site (don’t forget to include plenty of hard edges), and let them post the fixed-up image later. We can generously allow plenty of time for their “slow computer” and all, no hurry.

  15. Detail Man

    What a lovely idea, Martin ! … :)

  16. As promised, we followed up and had many emails back and forth with Adobe over the past couple of days, and in fact we created an whole new page on what they sent us…

  17. John Koelsch

    Get it out there, but don’t charge Leica prices.

  18. Tom

    The guy in the red shoes is very annoying.

  19. William

    Just tried the Photoshop CS6, and I can’t find the deblur thing…
