    Color Pseudoscience

    In the article he specifically says he chose it for Season 3 specifically for consistency.

    HELP! Fixing Rolling Horizontal Bands Due to LED Lights at Wedding with Flicker Free

    Yeah that's a tough one. Those flicker bars are moving so slow most deflickers may not work. You'll never get rid of them with just color correction. From the size of the bars it looks like you were super close to a working shutter but just short of it. Sadly some cameras just can't handle it...

    Purchasing my first LED light.

    Always go daylight. Full CTO is only 2/3 stop loss, Full CTB is 2stops. I would avoid gelling LEDs where possible though, crazy color shifts happen. Also day interiors and day exteriors are where you need more powerful lights and need them to be daylight, whereas losing output for a night...

    AC90A, FS700R or A7Sii for Green Screen?

    FS700+7Q would be an order of magnitude better than the others if only for compression. The rest only record to highly compressed interframe codecs which severely reduce certain frequencies of detail and heavy processing.

    Blown out colors under LED party lights

    Yeah even red and Arri have issues with primary colored highlights to some degree. Problem is when one channel is clipping the color science is basically guessing at how to render color since it's missing data from that channel besides that it is somewhere beyond clip. Seems to me the best...

    New Flexible LED Panels

    I just noticed there are a lot of new alternatives to the Westcott Flex LED series, including some inexpensive Chinese versions: Travor FL-3030 30x30cm Flex Mat (aka LF740) http://www.ebay.com/itm/371716486343 or http://www.ebay.com/itm/142090625468 Falcon Eyes RX-12T...

    Music/dance video shot on a7rii and fs700+7q

    https://youtu.be/vYD1UkN_KGI Just wanted to share this video I shot with basically no crew (just a PA to firewatch while I operated on location in brooklyn). It was all shot on my fs700+7q on sticks in uhd prores at 120fps and 24fps and on my a7rii always on a Nebula 4000 Lite gimbal. I shot...

    LED-How to tell the real ligthing output of led lights?How to compare lighting power?

    Really? I find wattage very useful both for understanding power supply and for getting a reasonable sense of at least luminous flux to expect given a basic knowledge of the efficiency of whatever technology is used. For example tungsten is around 25 lumens/watt, and just about all modern...

    LED-How to tell the real ligthing output of led lights?How to compare lighting power?

    The best way is to look at photometrics for similar beam angles. Anything else may not be giving you much to go on since different lights have different efficiencies and beam angles and technologies. Some lights are very difficult to compare because they cannot do the same thing so it's...

    Incandescent bulbs more efficient than LED'S!

    More details from MIT: http://news.mit.edu/2016/nanophotonic-incandescent-light-bulbs-0111 I guess they haven't broken 6.6% efficiency yet :( I guess that's about equivalent to a CFL though.

    Incandescent bulbs more efficient than LED'S!

    oOoh, sounds like it may be relatively inexpensive and easy to produce too if there aren't electronic components. Though I wonder how bulb life is and whether it scales up to high power outputs well. I wonder what implications this has for size and safety. Must be a significant redesign using...

    Most efficient lighting instrument under 1500USD

    Well there is a thread on here about $150 575w HMI pars. I picked up two (for $200+sh each) and it's hard to beat the price but there are big caveats that can be overcome if you either can live with some inconvenience or are willing to put a but more money into solving the problems. Basically...

    ISO steps how much light

    Yes doubling the number changes your sensitivity by a full stop

    Trying to get natural skin tones from Sony A7s S-Log2 footage using PPCC 2015 Lumetri

    Lumetri in Premiere works as an effect on a clip, and you can change the order of operations by using multiple effects in a particular order. Also, Lumetri does do color balance and exposure adjustments as basic corrections, before the LOOK/LUT is added. Separate Input LUTs may be applied...

    Slim mounting option for 7q+

    Here's my super light build for run and gun shooting. That's pictured with about 10-12hrs of batteries to get through the day without having to charge any. Plus a wireless lav kit since I just did a job that called for that. All packed in a small ThinkTank Airport Essentials Backpack I got...
