    David Sandberg has responded and said “This was an internal promo video that was never supposed to be seen by the public. I feel bad because it contains a bunch of plot points and temp VFX,” Sandberg told Variety in a statement. “I hope at least people can see the passion that we poured into the movie, the world deserves to see it as it was meant to be seen. This movie has been held hostage for the past 5 years but I promise to keep fighting for it and make sure this film gets the chance it truly deserves.”

  • Survivorship Bias: The error resulting from systematically focusing on successes and ignoring failures. How a young statistician saved his planes during WW2.

    pIXELsHAM.com
    Sep 25, 2023
    Featured, quotes

    A young statistician saved their lives.

     His insight (and how it can change yours):
    During World War II, the U.S. wanted to add reinforcement armor to specific areas of its planes.
    Analysts examined returning bombers, plotted the bullet holes and damage on them (as in the image below), and came to the conclusion that adding armor to the tail, body, and wings would improve their odds of survival.

     But a young statistician named Abraham Wald noted that this would be a tragic mistake. By only plotting data on the planes that returned, they were systematically omitting the data on a critical, informative subset: The planes that were damaged and unable to return.

  • Photography basics: How Exposure Stops (Aperture, Shutter Speed, and ISO) Affect Your Photos – cheat sheet cards

    https://www.pixelsham.com/2016/03/03/f-stop-vs-t-stop/

     

     

    An exposure stop is a unit measurement of Exposure as such it provides a universal linear scale to measure the increase and decrease in light, exposed to the image sensor, due to changes in shutter speed, iso and f-stop.

    +-1 stop is a doubling or halving of the amount of light let in when taking a photo

    1 EV (exposure value) is just another way to say one stop of exposure change.

    https://www.photographymad.com/pages/view/what-is-a-stop-of-exposure-in-photography

    Same applies to shutter speed, iso and aperture.
    Doubling or halving your shutter speed produces an increase or decrease of 1 stop of exposure.
    Doubling or halving your iso speed produces an increase or decrease of 1 stop of exposure.
