    Yes, I would like more bluescreens. At this point, I'd probably settle for a Bluestreak. But no, I don't want Michael Bay to have anything to do with a Transformers film.

    Can I just point out that your knowledge on "screens" is out dated. No one uses blue screens anymore. They use green screens.

    They could actually use any color but the problem is the computer takes out that color and replaces it with whatever background they want to use. I believe they stopped using blue screens because blue is a pretty common eye color meaning any actor with blue eyes would end up with the computer generated background showing up in their eyes. The computer doesn't know the difference between eyes and the screen, it just removes anything blue. Same thing with a green screen but green eyes are a little less common.

    Blue screens are still used, mostly when there's going to be something green in front of the camera. Sometimes the green-on-green will still work if the shades are different enough, but normally it's faster and cheaper to just bring in a blue screen for shots of green stuff rather than shoot on green, find it doesn't work and then have to source a blue screen in for the shot to be done again.
    Admittedly green screens are indeed the general norm now, but blue is still sometimes there as a stand by in case. And some effects, often fire and some smoke effects, are also shot in front of black screens.
    The eyes thing you mention does indeed happen but can be avoided by using differently-coloured contact lenses for some shots and/or the eye colour replaced in post if a shot shows the green screen has taken away an actor's eyes. It all depends how close or far away a shot is and if the director feels people will actually notice the small coloured area of the eyes has changed, especially in a fast-moving action scene.

    I remember they had trouble filming some parts of one of the Spider-Man movies when Spider-Man and the Green Goblin were costumed in shot at the same time as Spidey has blue in his costume and the Green Goblin obviously has green. Both blue screen and green screen gave them problems. Can't remember what the solution was though.

    The Osprey pilots knew what they were in for, like any soldier does going into battle. As for the team in the canals, they look more like reinforcements arrived in time to assist Lennox's team.

    That said, they could have probably used their heads and go for underwater canal sequences rather than go with an extensive human-Decepticon flight sequence, awesome as it was.


    Thanks for the update. But I think I saw some production videos of these films utilizing blue screens, which is why I mentioned blue ones.

    I actually am color blind so correct me if I'm wrong but isn't Loki's costume mostly green? Granted a darker green than the green screen would be but still understandable why they wouldn't put him in front of it. He's an exception not a rule.

    No. Go practical when you can. Bluescreen when needed.

    Regardless, your claim while 'correcting' someone was:
    Which means you stated it was an absolute about the non-use of blue screens now, which was incorrect, exception to the rule or not.

    love him, or hate him, at least he's not using bluescreens for things that can be just produced with out them. i respect him for his real shooting. that is something that James Cameron could do a little more of, in the next Avatar.

    ^This. By the reasoning you mentioned, I don't think blue screens are used any more or any less than they've been in the past.

    In the past it was always blue screens. I'm not sure what the reasoning for that was. I'm not even totally sure what the reasoning is for the switch to green screens. I'm just assuming it's because of HD video and wanting to actually be able to see the actor's eyes cause that's the only reasoning I can come up with that makes any logical sense. The end result is going to be the same either way, the color just gets swapped out for a new background. They could utilize any color screen and do the same thing, just make sure that any actor's clothing or props being placed in front of it aren't the same color as the screen.

    My mistake, you are correct. Green screens are used more often lately, mostly because of the switch to digital everything over the past ten or so years. Digital cameras have a higher sensitivity to green than blue (possibly due to digital stuff utilizing the RGB color spectrum, as opposed to CMYK). Also, green's apparently a hell of a lot easier to light.

    Apparently digital's higher sensitivity to green is because of the Bayer Filter Pattern which has more green pixels in it to better mimic the human eye's physiology:

    Bayer filter - Wikipedia, the free encyclopedia
    Chroma key screens are unlikely to use magenta or yellow when filming people because those are base colours in most human skin tones and you could end up with 'crackle voids' on peoples' faces if they have more pink or yellow in areas of their skin tone. I suppose they'd be fine for objects, but since studios already have green and blue screens kicking about there's no need for other weird colour screens.
    Blue screens were the first colour used because of the requirements of optical processes of the time. But it requires more illumination to light flat than a green screen does. So nowadays with the move to digital and wanting to use less energy for stuff, using a green screen instead of blue just makes more sense. I imagine though that if someone is filming on actual film stock rather than digital they might consider a blue screen rather than green.

    Objects with highly reflective surfaces can sometimes be a bitch to use any colour screen on though as obviously the screen gets reflected in the item being filmed and then that reflection area on the object will vanish too. That said, reflections in this instance are often replaced with digital ones anyway. You'll see a crewmember holding up one of those silver balls in a stick (can't remember the proper name of it offhand) in the environment to be added to the green screen shot to gain reflection and lighting data to be used later. Computer generated environments will generally have their own digital version of the ball.

    I was actually thinking more because CMYK is primarily used for printing purposes, whereas RGB is standard for digital screens. Lol. But your explanation works too.

    Absolutely not. Even with scenes on Cybetron, the more hard set you can capture, the better.

    Actually, it would be pretty cool to see more of Cybertron, and to see it actually built.
