    Yes it's experimental. We all realise that.
    No amount of analogies with mechanical cars and mechanical cameras (Super 16 film) will convince me they are relevant to software and processors though

    I think you guys should debate this in a new topic, because it's killing this one for the rest of us.... title of the topic is "What Magic Lantern reveals - 5D Mark III capable of 4K all along"
    I really mean it will all the good will in the world, please for the love of all that is holy open a new thread instead of using this one... I've nothing against you guys arguing about the science of dynamic range over 20 pages....
    Just put it in the proper place so this one can stay on the topic of Magic Lantern and the 5D Mark III raw. PLEEEASE!

    In principle RAW should be data directly off from the A/D converter. But that is hardly the case for most manufacturers since there is always some level of processing, usually selective noise reduction and gain for each channel. I would say that RAW data right now refers to just non deBayered data + some metadata. Log space just means to calculate the log (or other log like function) of the high bitdepth pixel value before you conform it to a lower bitdepth in order to maximize the information that is captured in the lower part of intensity scale. 
    So for example lets take 12 stops of light captured from the sensor and processed with an 12bit A/D converter:
     stop     1           2           3           4            5            6           7              8            9            10             11             12 
    0           2           4           8          16          32          64         128         256         512        1024        2048        4096
    if we were to scale that into 10 bits we would have these values:
    0           1          1           2           4           8          16          32          64         128         256         512        1024
    We just lost two stops of information in the shadows... So a log version of the original 14bit data, scaled to 10 bits would give:
     0      85         171         256         341         427         512         597         683         768         853         939        1024
    And that results in no loss of dynamic range by spreading the values for each stop equally across the bit range. 
    Of course things are a bit more complicated since the log function that is used has to take into account the sensitivity of the sensor, the color calibration and so on. For example you might want to assign more values to the midtones which most things are anyways, and less to the highlights.

    What the eye can do doesn't really matter. Because the brain can modify it any way it pleases.
    Our eye has variable dynamic range and HDR. We can expose for highlights, mids, and shadows all at one and the brain shows us a perfect 20 stop image.
    The brain is super fast and adaptable. If I remove one of my contacts I never have the chance to see the decrease in resolution and sharpness. My brain is way to fast in applying the proper corrections.

    So trying to mix DR from a camera with that of screens is already a bit weird. I know some say that 13 stops isn't needed if a screen is only 10.. just wrong. With the 13 in the camera I can adjust more info into the 10 for the screen. Simple as that.

    To add the eye into the mix is just silly imo.

    Well, getting back onto the subject of the 10bit and 12bit lossless 3.5K raw on the 5D Mark III, I can safely say it's the best QUALITY dynamic range I've ever used in post. I can correct for huge exposure differences and there's no crushing of the shadows / blacks at all.
    So I agree in that I'd rather have a high quality 10 stops or 12 rather than a compressed to hell 14 stops that's for sure (*cough cough* S-LOG 3 *cough*)

    Next to the X-T20 its going to cause some serious doubts on which to buy for those looking to get in at the mid level of the Fujifilm system.

    Personally I love my X-Pro2 more than the X-T2 I had or the X-T20 I get to use at work.
    And here I would probably go for the X-T20 since this doesn't have an OVF anyway.
    But it still is a tasty camera.
    The good news is that predecessors like the X-T10 and X-E2 costs seriously nothing only a few month after release where I live.
    Even  the flag ships are starting to plummet since Sweden is still hardcore DSLR users.

    They are really on the ball. I feel the respected as well and they have really supported EOSHD with this roll-out of the firmware.
    I feel every penny of the investment I made in the GH5 has been rewarded with this update, and the ALL-I codec is stunning.
    This is a Hybrid Log Gamma / TV thing, you are best off using H264 for everything else especially the 400Mbit ALL-I. Due to the high efficiency of H.265 it only needs half the bitrate of H.264 for the same quality so it is good for saving space, but it doesn't quite have the filmic motion and fine grain of the ALL-I H.264.

    Justin Bacle reacted to Andrew Reid in Nikon had 4-stop "Speed Boosters" in 1995   
    Developed together with Fujifilm -
    https://en.wikipedia.org/wiki/Nikon_E_series
    "Its unique optical system bundles the light of the full frame lenses to the small 2/3 inch CCD sensor. That gives approximately 4 stops more light at the small sensor, therefore delivering an exceptional (for that time) minimum sensitivity of 800 and maximum 3200 ISO, which remains usable for press and news use."
    They fitted a 36 x 24mm full frame image into a 2/3" sensor!
    The E series uses a unique additional optical system that enables the small sensor to capture the field of view of a 35mm film, with a crop factor of 1. This comes not at the expense of the lightness of the lenses, because the light is bundled to the  2⁄3 inch CCD sensor with approximately  1⁄16 smaller area. The result is approximately 4 stops (24 = 16) more light at the small sensor compared to a full-frame sensor. Therefore the camera has a minimum full-frame sensitivity of ISO800 which is equivalent to ISO 50 at  2⁄3 inch. As a result the noise of the camera at ISO 800 full-frame is equivalent to ISO 50 of the  2⁄3 inch CCD sensor. Nikon could not reduce sensitivity below 800 ISO full-frame, because the little sensor will be overexposed below 50 ISO.
    I am sure the corners are soft but heck would love to see a modern version of a focal reducer this dramatic for Micro Four Thirds
    Medium format on the GH5 anyone?
