Green screen lighting for betacam
Posted by Robert Pukas on February 12, 2010 at 4:28 pmHello,
I am trying to get good green screen. I am shooting with sony d600 betacam camcorder and my question is what amount of light I need to light the green screen? Currently I am lighting my green screen with 2 x 2kw softboxes but my video has a lot of noise. I though maybe my camera is bad, but took it to local service and they told me that I D600 needs a lot of light. So how much light do you use?Paul Hudson replied 16 years, 2 months ago 4 Members · 6 Replies -

February 13, 2010 at 7:32 pmYou want to light your green screen with the same intensity as your subject. If you are using any plus gain on the camera, you are introducing noise.
The first rule of green screen is to light it evenly all over. Sounds like a starting place would be to double the number of lights. But be sure you place them so the screen is illuminated evenly.
It is also possible your software is introducing noise though more likely it is the lack of light.
There are lots of posts on shooting green screen. If you are still having trouble, try searching the data base.

February 15, 2010 at 3:04 pmThank you for your reply. I searched the database but didnt find anything about shooting with betacam.
My question was how much light ( in watts fluorescent or halogen) do you use with betacam camcorder to get good key?
I cant believe that 2x 2kw halogen softboxes is not enough to light green screen( I get noise…)
My camcorder is sony bvw-d600p -

February 16, 2010 at 4:02 amA too-obvious question, perhaps, but are you shooting with the ND filter on, or the 2x extender engaged, or a lot of shutter turned on? My boss and I one time, years ago, had quite a laugh after an hour of adding more and more light to a scene without getting to a good picture or lens opening, until I finally noticed we’d left the ND filter, shutter and daylight filters on from the previous outside shoot.
DOF effects were AWESOME, tho:-)
