    Few remarks.


    1) Judging noise, texture and resolution (acuity) tests and image quality in general over web compression is misleading.
    In the contex of noise, this can mislead in two ways:
    a) appear superior than it actually is (when compression smoothens irritaing noise) and
    b) appear worse than it actually is ( when compression accentuates noise into more visible texture instability, like splotches or compression blocks) -
    while in reality it is much finer and less noticeable


    2) Digital "ISO" approach is best perceived seen through two priorities:

    A) Image quality
    B) Priority to get the shot at any cost

    If priority is image quality, "Thou shall not imagine sensitivity and stretch the bits". Forget the other numbers. Because no additional data is captured past the base analog gain. It is not just the noise levels. It is stretching of the captured bits to appear as something which was not captured, which significantly reduces image quality and significantly decreases the range of image manipulation in post.

    If priority is getting the shot (documentary, event coverage without any control of the lighting, one shot opportunity without any setup alternative etc.) and otherwise there is no shot, and footage won't see proper post... the route has a justification to differ.

    Surfing in the middle at a whim, just because it's there, treating post image push as a camera exposure control by shooting at digital equivalent of ISO which just "seems okay" due to "tolerable noise" at a glance, is just destroying the image in multiple parameters and all the resolution, image colour and depth performance advantages, as well as post production image shaping ability - fly out the window straight in a dumpster.


    So to put this in the context with S1H - The question whether this and this ISO is usable...needs a context "for what".

    Hrvoje,


    I think if a few Raw(H.264 clips out of camera) clips at maybe a few of the ISO's under or around the 10000 ISO range would have allowed for a better assessment of the actual "useable" noise range for "professional" standards. I know you had access to the camera, in your experience, what did you find to be a "useable" range for "professional" use in both controlled and uncontrolled lighting situations when image quality is the priority?

    There is no single, simple and generally applicable answer to that question.

    1) "Professional" covers a wide range, from TV and cinema to event coverage, documentary, corporate, wedding...etc. Priorities differ.

    2) ISO equivalent push results differ depending on
    a) light temperature and quality - determining colour channel balance and saturation proportionality
    b) scene light intensity and exposure levels - determining overall sensor saturation and what is being pushed
    c) recording quality - affecting bit depth, spatial resolution and tonal resolution which together determine image definiton

    With regards to a) and b) - with same ISO equivalent value:

    Bright scene shot under natural light will have one camera response.
    Dusk scene under natural light will have another.
    Night scene another.
    3200K controlled light well lit scene another.
    3200K lit dark scene another.
    Scene under street lights another.
    Scene under different street lights another.
    Scene under mixed light combo 1/2/3/etc another.
    Dark city street another.

    You get the picture.

    In the example of two diametrically opposed shooting scenarios - you cannot expect the same ISO performance in
    - a brighter scene under natural light where the image signal is well balanced and most of it is in mid and upper range
    and
    - a dark city street with channel starvation, colour spectrum circus and most burried below 30%.
    Not even close.

    S1H ISO4000 covers wide range of usages. There is some shadow detail softening but nothing major. Chroma noise is well controlled.

    From that point, increasing the digital image push, usability and results depend on everything mentioned previously and individual or production priorities and criteria.

    To have the best insight and avoid image quality problems, one should test the camera and results before the project in same shooting conditions the project will be shot in. When possible.

    Yes i just jammed it to the mixer once in the morning. I'm pretty sure it even held through battery changes. Jamming is so fast, I just did it every time we changed mags on the RED. We were shooting long interviews, the S1H Was BCam and Broll Camera.

    S1H with CANON Sumire lenses. I recommend turning the sound off :-)
