  1. no, i don't think other cameras are compensating for it. you would see this on any camera. it's light. you *could* use secondaries in post to counter it but that's treating the symptom not dealing with the problem on set. in the first, what we typically would do is replace all the fluorescent bulbs in the ceiling fixtures with daylight balanced ones. or in the second case, they could have done what I've seen Tak Fujimoto do and lay down white sheets out of frame so that the light bouncing off the ground becomes a soft neutral fill.

  2. again, i don't think this is a color science issue. look where they are standing. by noting the nearby background you can infer that the grass they are standing on is brightly light by the sun. all the green you see is presumably light bouncing up at them. look at the underside of their arms, etc.

  3. that green cast in the shadows looks like an effect of the light in the room to me. if you look at the ceiling behind them, there are some fluorescent lights that are greenish.  so anywhere that their own light set up (probably 5600k) isn't hitting them strong, essentially has a greenish fill light on it -- shadow areas on their clothing and skin, and the entire store behind them has the green cast.

  4. You can record internally. In fact you get a larger 4:3 frame that way. 3328 x 2496. albeit, 8bit 420.  I believe the reason why you can't monitor this over HDMI is because it needs to be embedded within an existing 4K frame that external devices can recognize and display (and record). If you set HDMI out to 10 bit 422, the 4:3 frame is reduced to 2880 x 2160 and embedded inside a 4K frame with black bars on the sides (pillar boxed). in this latter case, internal recording is disabled. 

    ​I finish everything in 2K so that's still plenty for me. and the addition of 10bit 422 is welcomed.

  5. I have the GH4, the SLR Magic 2x Anamorphot, speedbooster and the Sigma 18-35mm. The combination works, but only at 35mm. The rest of the focal range vignettes. without a speedbooster, you can go down to 24mm. and this is only if your target aspect ratio is 2.39:1, otherwise you get a vignette. If you want that crazy 3:55:1 aspect ratio from shooting 2x anamorphic to the GH4's sensor in 16:9 mode, you'll have to use a 50mm at a minimum. 

     

     

  6. I'm thinking about going with the Micro Cinema Camera for this reason. 1080p, 13 stops, global shutter option, MFT mount. $1000 and will swap out nicely with the support gear I have for a GH4. I'll pull the trigger on a 4.6k EF mount URSA Mini later this year.
