    God how I dislike the colour-shifted cyan skies I have to look at in
    photos. The sky is NOT cyan, it is blue. The deepness is different
    as you go further or nearer the Sun, but the colour is always blue,
    barring sunsets and particulate contaminants in the air (like from
    industrial pollution or volcanoes). I have NEVER seen a cyan sky
    "live" in my life and they should work to figure out how this can be
    purged from censors.

    Actually, the real color of the sky is black! It only looks blue due to
    bending and scattering of light caused by the earth's atmosphere. Look
    at the pictures the astronauts brought back from the moon: The sky is
    black.

  3. You really do need to get out of your mommy's basement on occasion. The sky
    is indeed cyan on occasions. The color of the sky depends on many things.
    The time of day, the amount of air-pollutants, the humidity, and even the
    sky-glow caused by electrical discharge (something that astronomers and
    aurora-fans are all too aware of). The color of light reflected from the
    earth's surface below the sky, it too vastly changing the color above at
    times.

    But I strongly suspect that your sky is more plaid or argyle in your
    mommy's-basement world. So how would you ever even know of these things
    that often change the color of the real sky. At least the one on earth. The
    vote is still out as to which planet you call home.

    Please Rich! Let's not have a Sisker redux moment.

    While pure cyan is an inappropriate color for normal daylight sky, I
    would hardly call the color you are bitching about in the sample you
    have presented "cyan". I that the faded blue blend of a shot through
    haze.
    ....and as you have stated, sky color is not locked into any single tone
    of blue, you can also add a variety of blends of magenta, red, gold,
    grey, all dependent on atmospheric conditions, and somewhere in that
    blend of colors cyan will have a role to play.

    Let's just remind ourselves of the Tyndall effect and Rayleigh
    scattering. Just to keep things simple check <

  5. You need to look out of the window and check your facts!

    Only today where I am it was the following colours

    Morning grey
    Early afternoon sky blue!
    Later afternoon cyan (well much lighter blue anyway)
    Early evening red
    Now black

    That looks like a typical Australian sky.

    I guess now's probably a bad time to ask how the Hubble is able to produce
    images that are vibrant in color and not B&W?

    Considering the cloudy haze behind that sweetgum tree,
    it's still a light (baby) blue to me, not cyan.
    Maybe you need to adjust your monitor (lessen the green)?

    (wtf)
    censors
    sensors

    If you must harvest a nit, maybe select one from the same vine.
    In the referenced photo the 'sky' part is from a terrestrial perspective,
    as evidenced by the 'earthly' type dwellings,
    not out in space, or even the surface of mars.

    It's because for the last 27 years, 4 months and 17 days all new sky has
    been made of...PLASTIC! I'm surprised that RichA didn't know this.

    Because its images of objects and not the void between them.

    The histogram isn't blown, which can be a problem if the blues go off
    the right edge in an RGB histogram but that's not the case here.

    heh

    The solution is negative exposure compensation, then boost in post but
    that makes the shadows more noisy, particularly skies if you don't need it.

    Doesn't matter. For all this technological mental-masturbation (i.e.
    distractions from the REAL problem), I've yet to see any of you produce any
    images where noise even matters. Let alone knowing how to use it to
    effectively enhance an image. The subjects and compositions themselves are
    more than enough to detract from anyone wanting to view any of them for
    more than a second. The latest SI being yet another testament to this
    glaring fact. As will the next one, and the next, and the next ...
    Welcoming known and proved photo-thieves into your T-Ball leagues isn't
    even a small part of the main problem that all of you need to, but will
    never, address.

    Or us, you.

    The real noise is you flapping your gums about something you evidently
    can't do: take good photographs.

    Thanks, for finally admitting that you don't know how to use any camera.

    I guess you forget all the throw-away images of mine that I posted to
    counter Anika1980's beginner snapshots. To prove to him that I can outdo
    him even with a 2 megapixel P&S camera, no matter the subject. That's why
    he no longer posts his crap here after all his years of doing so. I
    publicly proved him to be the snapshooting fool that he is. You, on the
    other hand, fall much more sharply into the "moron" category. You can't
    even tell how ignorant and stupid that you are, so you persist in proving
    it time and time again.

    How long since you calibrated your monitor? That looks the same colour
    as the sky outside my living room.
