  1. New Ultrafast Camera Takes 70 Trillion Pictures Per Second



    A team of researchers at Caltech have developed (yet another) camera capable of capturing over a trillion images every second. The previous “world’s fastest camera” could shoot 10 trillion fps; the new camera can capture up to 70 trillion, smashing the previous record.

    For those who enjoy back-of-the-napkin math, the speed of light is (just under) 300 billion millimeters per second. Now, take 70 trillion frames/s and divide it by 300 billion mm/s, and you get ~233.3 frames for every millimeter the light travels. Put another way: this camera can capture about 230 frames in the time it takes light itself to move one millimeter.

    The link above contains an example of the "footage". 
    A couple of more comprehensible examples from a previous iteration of the camera here (https://www.caltech.edu/about/news/ultrafast-camera-takes-1-trillion-frames-second-transparent-objects-and-phenomena):

  2. Cretins always find a way.


    Facebook group Taking Photographs Is Not A Crime shared a post from an unidentified Facebook user, declaring why they were suddenly refusing to shoot film.

    The post says: “So I’ve taken the difficult decision to give up using film until the current crisis is over. Film uses gelertine [sic] – and that is what laboratorys [sic] use to grow virus on – so your film can carry and spread the corona…”





  3. Perfect example of ad hoc ethics.  We, mankind...


    Texas Secession Convention, A Declaration of the Causes which Impel the State of Texas to Secede from the Federal Union, (February 1861)


    based upon an unnatural feeling of hostility to these Southern States and their beneficent and patriarchal system of African slavery, proclaiming the debasing doctrine of equality of all men, irrespective of race or color-- a doctrine at war with nature, in opposition to the experience of mankind, and in violation of the plainest revelations of Divine Law.  


    We hold as undeniable truths that the governments of the various States, and of the confederacy itself, were established exclusively by the white race, for themselves and their posterity; that the African race had no agency in their establishment; that they were rightfully held and regarded as an inferior and dependent race, and in that condition only could their existence in this country be rendered beneficial or tolerable.  


    that the servitude of the African race, as existing in these States, is mutually beneficial to both bond and free, and is abundantly authorized and justified by the experience of mankind, and the revealed will of the Almighty Creator, as recognized by all Christian nations  [...]





  4. I had no idea this product existed.



    Automatic Filming.
    No cameraman? No problem.

    Film yourself with SOLOSHOT, the Robot Cameraman. You wear the Tag, and
    the Base automatically pans, tilts & zooms to keep you in the camera's shot
    up to 2,000 ft. away for over 3 hours. No line of sight required. 


    From the FAQ  (click on "Learn More" in the web page):

    Can I use any camera with SOLOSHOT3?

    We recommend our OpticX high zoom cameras that have been specially
    designed to be pointed by our little robots. If you're a DSLR or GoPro ninja, you
    may connect those or other 3rd Party cameras to your Base using the Camera
    Adapter accessory and recommended cables.






  5. The OP video is made with a GH3.  

    Quote from the interview ntblowz has linked to.  

    Leonardo Dalessandri, on the gear he used in the making 
    of Watchtower of Turkey:  

    What equipment did you take on the trip?

    When you are on the road shooting a personal project you cannot
    bring loads of equipment.  Besides my two cameras, the Panasonic
    GH3 and the entry-level GoPro3, I had my MacBook Pro 2013 and
    two LaCie rugged portable 2TB drives.  I didn’t use anything else.  
    No sliders, no mounts, no stabilizing gear.  I had a little tripod, but
    I did every shot hand-held.  

    I had three lenses on my GH3: a Lumix 12-35 f2.8, a cheap 14–140
    zoom lens and my favorite: a Leica 42.5 f1.2 nocticron.  On the
    screenshot you also see an old Sony camera that I did not use.  
    Most of the footage in the video came from the GH3.  

    I also took a little Tascam audio recorder.  It is very cheap but very
    cool for what I need when I’m traveling.  We used it to record
    typical ambient sounds at the places we visited: people, street noise,
    water, a flock of birds flying by, a call for prayer, etcetera.  Those
    specific little sound bites are extremely important in the final edit
    because they can add a lot of impact to the visuals.  

    The video footage was recorded in 1920x1080 format.  For the GH3
    I used the all-I 25p, 72Mbps, H.264.MOV setting.  I also shot hyper
    lapse sequences in photo mode.

  6. HUMAN. The Movie. What makes us human.

    Forget for a second all the stupid things we worry about,   APS   FF   s35   UHD   FPS  
    DR   IBIS   ISO   DOF   RAW   LOG   LUT   THEFUCK, all those stupid things.  Human
    shows (spoken) portraits of people around the world and (aerial) beautiful,
    extraordinarily beautiful, views of the Earth.  Get your favourite armchair and wonderful
    4K display and 90 minutes for yourself and watch it.  Or use your 7 inch tablet whilst a TV
    is screaming in the next room.  Watch it.

    Human is made up of 200 incredibly personal portraits. Interviews with people from
    all walks of life, and that expose many aspects of what makes us human.


    Human has just been released in several formats (more info on the official site).
    There's a special extended version (3 volumes of about 90 minutes each)
    that can be watched on youtube thanks to an arrangement with Google.  It is
    available with embedded subtitles, and there are more languages than the three
    I show here.  Choose the one you feel more comfortable with.

    “I dreamed of a film in which the power of words would resonate with the beauty of
    the world. The movie relates the voices of all those, men and women, who
    entrusted me with their stories. And it becomes their messenger.”
    Director Yann Arthus-Bertrand


    There is a lot of behind the scenes info here, but I'd suggest going there only after 
    you've watched the movie.

    (I must confess I couldn't avoid thinking in terms of sharpness, 
    lighting, and colours.  But that's because I'm stupid.)


    These three voices – People’s word, Earth’s testimonial et Music’s lyrism –
    act together to provide a single voice to our humanities.
    As an ode to humanity, HUMAN is a rare collection of stories, faces and fates.
    Yann-Arthus Bertrand takes us into an immersive experience through
    human destiny. Through several witnesses who succeed one another
    and confide, the film director portrays a contrasted humanity.
    Through the aerial sequences, Yann Arthus-Bertrand shares his vision of the world
    and the people with the spectator, and offers a poetic and critical insight
    of our planet. In HUMAN, the camera lens reveals places of an unsuspected
    beauty, but also poses a careful look at the lives of men worldwide.
    As an universal language, music transcends our emotions,
    sublimates the pictures and rhythmises the story.

    Canon Japan just announced that it has developed a new 250 Megapixel APS-H sensor.
    The sensor read out 1.25 billion pixels per second. I guess your 50Megapixel Canon 5dsr
    looks like a real loser now :)

    Here is the official press release:

    TOKYO, September 7, 2015
    Canon Inc. announced today that it has developed an APS-H-size (approx. 29.2 x 20.2 mm)
    CMOS sensor incorporating approximately 250 million pixels (19,580 x 12,600 pixels), the
    world’s highest number of pixels1 for a CMOS sensor smaller than the size of a 35 mm
    full-frame sensor.

    When installed in a camera, the newly developed sensor was able to capture images enabling
    the distinguishing of lettering on the side of an airplane flying at a distance of approximately
    18 km from the shooting location.2

    With CMOS sensors, increases in pixel counts result in increased signal volume, which can
    cause such problems as signal delays and slight discrepancies in timing. The new
    Canon-developed CMOS sensor, however, despite its exceptionally high pixel count, achieves
    an ultra-high signal readout speed of 1.25 billion pixels per second, made possible through such
    advancements as circuit miniaturization and enhanced signal-processing technology.
    Accordingly, the sensor enables the capture of ultra-high-pixel-count video at a speed of five
    frames per second. Additionally, despite the exceptionally high pixel count, Canon applied its
    sensor technologies cultivated over many years to realize an architecture adapted for
    miniaturized pixels that delivers high-sensitivity, low-noise imaging performance.

    Video footage captured by the camera outfitted with the approximately 250-megapixel CMOS
    sensor achieved a level of resolution that was approximately 125 times that of Full HD
    (1,920 x 1,080 pixels) video and approximately 30 times that of 4K (3,840 x 2,160 pixels) video.
    The exceptionally high definition made possible by the sensor lets users crop and magnify
    video images without sacrificing image resolution and clarity.

    Canon is considering the application of this technology in specialized surveillance and crime
    prevention tools, ultra-high-resolution measuring instruments and other industrial equipment,
    and the field of visual expression.

  8. I recently came across the below video and thought it looked pretty good. This was shot on the NX1. I think it shows that the NX1 can truly be as professional as you choose to make it. In the right hands it can produce very good results. For me this really does beg the question that I'm seeing popping up more and more... Is it worth it to spend $3k + for  a camera body when your story could be just as compelling being filmed on a more budget friendly option. And before anyone brings it up, yes yes yes I know about the transcoding from h.265 overhead, but I suspect the downside of h.265 will soon be an upside as support for the new standard becomes widespread. Indeed, in due time I have little doubt many will be seeking out h.265 cameras.

    Some information on the settings of this shot can be found 
    in this post, from page 5 onwards.  By the author himself.
