My Green Screen

As you can see I have hot spots from the light fixtures, I have one on both sides. I built it so the lights would mount directly to the frame of the screen for convenience. I was thinking I just need to adjust the bracket a few more inches from the screen, and diffuse the light a bit. Any thoughts?

The stands I built give it a lot of stability. They are solid 4x4's enclosed with 3/4" solid hickory. (Doing hardwood floors does have its advantages)

The screen dimentions are 9'wide x 7' high.
 
kdawg, I think it looks great!

Just what you said, move lights further from the screen, and diffuse... excited to see your test shots.

PVC never had it so good with them fancy-pants stands. Also agree that moving the lights away should help.
 
Kdawg,
Looking good. let me know how it turns out. I'm in the process of making one for myself, but mine is going outdoors, and is going to be 30'x10'. Once I finish the set up which I haven't had time, I'll post some pics.
 
Yeah, the material looks really good. What is that? Doesn't look like muslin. As for lighting, I would move it back just a little bit. What color temp is the light -- looks like daylight right? Also, where does the back leg join the rest of the frame? I see two legs...
 
ok, let me post somemore grabs in a bit here. Hey Chuck, I dont know what the material is. I just went to the fabric store and this was the only stuff in the bright annoying green color I could find. It worked out perfect because it stretches so far, and gets rid of the wrinkles. It is a bit translucent and I thought about mounting the lights in back, but if the lights are too close, you can see the tubes right thru it. But I dont think enough light gets thru it otherwise. I may give some more thought and tests into that.
 
The lighting is genius. Having it attached makes a huge time saver and all the difference in the world. What did you use? Are they just Fluorescent lights? Did you need a balast?
Maybe have the lights on Arms that swivel out so they are not so HOT on the screen.

Did you build a support frame along the back? using 90 elbows? Nice stands by the way.
As for the lighting you'll want it as even as possible, maybe mount it overhead and angled down towards the screen.. Though the idea of having side mounted lights for fill is pretty nifty.
Good job
 
How about overhead AND at the sides. Seems like the more coverage the better. I would definitely get the side ones a bit further out if possible -- like 3 or 4 feet.
 
Thanks for the ideas guys. I have decided the 3/4" pvc is a bit too flimsy for the lights. I am going back to the drawing board this weekend. But I did do an interview for a project Here is a screen grab

Dude,did you light the subject separately? the tricky thing with green screen is always the spill and lighting the subject separately with a gel on the lights is essential to getting perfect results.

i tried a similar build with PVC myself and also found it to be too flimsy. GENIUS idea about habing the lights attached to the green screen.
 
Joann's fabrics.

and Puck, I did light the subject with an incandescent light you can see a slight shadow on his right, and warm color on one side with the flourescent on the other. But hey, the people I am doing it for will love it.
 
Looks good and I like your idea a lot. You should have your talent move toward the camera more to avoid any shadows on the green screen though....
 
Lighting, lighting, lighting. Get a light meter and spot-check every section of the screen that will be in frame. The more even your light is, the cleaner the key will be. If you can see shadows or hotspots with your eyes, the camera will only see things worse.

Some cameras (including the HVX) will let you set the limits of the zebra stripes. If you set them down a bit, you can zebra-stripe your screen to make sure that everything is even (it all zebras at the same level).
