Well try it out and see if it works

The clip rendered at 720p looks natural I can maintain very thin strands of hair many from the Add composite. Which normally I would have keyed out

On some shots when you key out the green you get an alpha bur which looks ugly so instead of crunching this,turn it into light, as the light will be dictated from the background this will also work for backdrops that are under exposed.
Where there is light it will effect the key and where it is dark it will not. much like a natural key light

Or no….bad idea.............How much alcohol was involved in this idea?

So, in essence you are "creating" a better GREEN screen than was there? Is that it?

Grazie

ps: bur = blur?

Here's a really radical idea.
Use scotchlite reflective material and light it up with UV lamps.
Sounds crazy doesn't it but it was used in some scene of Avatar. Apparently you get no green spill, I guess because the green light is being emitted from the fabric rather than bouncing off it. The cameras don't see the UV or even if they would it's easily filtered out in front of the lens.

Grazie…… bur = edge like in etching

Yep trying to get it better

Bob that’s a great idea I know the stuff, its made with layers of tiny glass beads.Used in road sign manufacturing. Expensive

Ah! Yes, I'm glad I asked . . .

The "beads" thing I saw from a company, showing at the shows for the past 4 years(?) - maybe?

Grazie

Yes, the glass beads thing is old. With that you fire green LEDs into it, usually from a ring light around the lens. It works but it is expensive.

This idea is way beyond that. The material has a flourescent dye in it, commonly know as Dayglow. The UV light makes the fabric glow green. The idea originally came from Weta Digital, guys there were using it to green screen minatures.

I've had the best GS results with the neon poster stock at WalMart.

BudWzr - The Wal-Mart neon poster stuff works great for miniatures - I've used it. Have you ever used it on larger projects? If so how did you do the seams between posters?

I only use it for macro work. For bigger stuff I use something from IKEA for $10. It's a childrens blanket, one side is green the other is yellow, the material is like flannel. It's not shiny at all and no shadows. Let me look it up and I'll post back.

Here it is:

http://www.ikea.com/us/en/catalog/products/80155390

It's $13 now.

The blanket can be stretched taut on a frame, or used loosely to cradle a baby, and stores away easily.

P.S. When I need "chroma green" paint I take the poster paper over to the paint dept, and they can color match it, but it has to be held loosely in the scanner eye so some light can get in there. I have a custom color saved in their computer now after I got a particularly whacky (good) green last time.

If you can get a close match, you might be able to do the seams with it. I would butt the seams together and use 3M Super 77 on top of a 4X8 foam panel from Home Depot ($10) then paint the seam. Those panels at home Depot look and feel like styrofoam, but are EXTREMELY durable and flexible.

Problem with the foam panel is storing it unless you have a studio or garage, and it's not as flexible once the posterboard is glued to it.

I'm concerned about foam panels - most emit a highly toxic smoke in case of fire; for that reason, most building codes require foam to be separated from interior living spaces by 5/8" plasterboard (preferably type X).

I can understand that, I got a whiff of a house fire one time from the sidewalk, and the smoke is so thick and horrific that I started choking immediately, it was toxic enough on its own. Probably two breaths and you're a goner.

BudWzr: Thanks for the blanket tip! I can probably use it.

good point LR.Fire is a real issue to consider,once shooting a tv commercial in a studio that produces soapies the syke caught alight from the heat generated from the lights…..twice on the same sequence
Fortunately extinguishes were part of the kit…do you have one as part of your light kit????? I don’t… better sort that out

I suspect there are some on this Forum who wish you'd taken that second breath.
