    I think Jarred mentioned the losses associated with the Beta and early ST cameras were the result of paying engineers to hand assemble and QC them. Compared to normal assembly line costs, labor for...

    The physics of large screen projection limit maximum photometric DR to 500:1 due to backlight scatter from the screen. That is 9 stops. The minimum SMPTE theatrical target is 150:1, which is 7 stops....

    Stunningly beautiful images. Love the clean, crisp, richly colored HDR look.
    Any chance you could share some .R3D still frames for us to play around with?

    My first choice would be an LG OLED, but dialing in the optimum settings is a complex process. The menus are extensive and access to some with their magic remote seems to depend on what the source...

    Hard to tell without messing around with the raw clips, but I did not see much of anything in the street scenes that would make me want to shoot those above 800 ISO or maybe 1600 max. Looked like...

    It is useful to think of native ISO as defining optimum exposure sensitivity required to saturate the sensor with light in the same way you would expose film to get a rich, full dynamic range image. ...

    Looks to me like the log curve is over exposed and clipping at the top by just a bit. That shelf in the peak white response doesn’t look like part of the curve.

    Boy, talk about lens porn! I give it five drools. :drool5::drool5::drool5::drool5::drool5:

    Lovely piece of glass though.

    I'm super interested in this too for the same reasons. Have some vintage C-mount primes from Bolex 16mm days plus a really fine Angenieux 12-120 HEC that would make a great run and gun lens for 2k....

    Current generation premium HDR consumer TV's support 12 bit 4:4:4 media input though most only display 10 bit. Consider that capturing 16 bit or 12 bit raw gives you far better access to the...

    Hi David,

    My wife and I started binging a couple of episodes a night of The Marvelous Mrs. Maisles series recently. Really love the richly colored almost surreal look of it. Beautifully done. ...

    There is no difference in a still frame snapshot and the moving images from Komodo, unlike any DSLR. You can see much more of Komodo's qualities from these stills than you would ever get from a...

    There is a lot more room for highlight recovery in RCX. Simple picker white balance on the half wall behind the couch solved the magenta cast. I love the fine color discrimination. The lower front...

    The firmware is still in beta. Do we know for certain that Komodo won’t do 50fps at 5k or is that just a limitation of current firmware?
    It does 50fps @ 6k 2.4:1 apparently.

    I prefer an EVF mounted close to the balance point. Bolex 16mm style worked well with small primes, but was tiring with larger zooms.
    This rig is very comfortable to carry for hours, as I have...

    Canon's 10 bit 4:2:2 codec is pretty robust. Most Canon shooters would probably just use that. The universal complaint about the C200 was it did not have the Canon 10bit internal video codecs.

    Based on the Zyla charts posted, Komodo seems to be pretty much on par with Gemini and Helium for DR. Might be half stop difference. Exceptional for a camera in its price range.
