I have read many topics about green/blue screens on this website and on other websites, but i cannot figure 1 thing out:

Why dont people shoot there greenscreen footage outside on a day with clouds?

Today i walked outside and there were absolutly no shadows at all.

I have shoot greenscreen inside with lighting and there just keeps shadows popping up...

So i think shooting outside on a cloudy day is the best option.

Can someone explain to me why shooting outside (cloudy day without any lights)
Is not better than shooting inside?

Thank you!

Well if it's a cloudy day outside you can't get much light to bring out the green in your green screen, even though there wouldn't be any shadows. But inside if you have three really good lights (one to point from the right,left, and above) you can remove all shadows and get a better color out of the green screen (and the actors for that matter).

it's all about controlling the light. Indoors you can ALWAYS have control, it's practically guarenteed. It sounds like your method was successful, but for major planning, how could you depend on having the day be cloudy for the green-screen shoot? that's the problem

plus outside increases the chances of your greenscreen getting dirty or broken. it's expensive so you don't want to really do that.

I have not test it myself yet,
i have only shoot a short thing inside on school, but outside is the most natural light source and there are no shadows.
(cloudy day)

But your are right about planning a shoot, you dont know when its a good day outside to shoot, inside you have full control.

But what abbout "no" budget shoots?
And shoots were you dont have to plan the day
(for example: if you just shooting yourself or a friend)

That's a good point about lighting control. When I shot my doc on this artist creating a sculpture, his studio had these great big skylights in the roof. On a sunny day, the lighting was great.

But a partly cloudy day was the worst. The light would go from great to lousy to great to lousy as the clouds passed by. Very difficult!

But beside you cannot control the lighting,
and must wait for that good sun/clouds combination, it can be done?

I meen, it can be done easyer and better outside when you wait for the good moment?

Yes, i understand that you cannot do this on a shoot that requiers planning.

Thanks for the anwers,

Hello again,

I have 1 more quistion,
i have read tons of topics around the internet about green vs blue, but i cannot find the very bright green in cloth material, so i have 2 options:

1. i use blue material
2. i use darker green (normal green, not than very bright green)

I want to use cloth, paint is not an option,
what do you think: "dark" green or blue?

Thanks,
Jerry

I don't think dark would work very well. I've never tried though. Maybe you can find a small sample to test it with, but I think the idea is that the green channel in the video would be almost pure when you use the bright green, whereas with the dark green it wouldn't.

Yeay, i think you right, otherwise there is no reason that the normaly used green is so bright,
well, i think i must go with blue than...
Thanks

Well, i have found some green!

Can someone tell me of this is the right color? (i know that all colors can do, but the right color in terms of green, is this good green?)
