One of our Lowell hotlights fried yesterday. A wire was rubbing against something. Shorted out, melted a hole, stopped working. Just when we were finally ready to really go full-steam ahead. We had to light the bluescreen with one light. We tested it and found it keyable, though. Nothing every works perfectly it seems.
The garbage matte is cutting off a wee bit of his head. Just a quick little comp. We like it. We've established a quality level; not spectacular, but we like it. We did 7 shots yesterday. They're just the model huffing and puffing with some head movements, but hey. That's alot of stuff in the bag for one day. Gonna see if we can't polish off his shots within a few days.

The main problem is always the same; we key out our green, but it also removes some pixels from our puppet, resulting in a hideous dancing grain. It's been frustrating, because it feels like we're doing everything right. We've been reading the instructions. And Dave has the photographer training. Switching the Keylight view to 'screen matte' shows us that we've got a clean result. Likwise with 'status view'. The only thing that killed the grain was switching to 'Intermediate view', which disables the spill suppression. So our problem is spill. But we put the puppet on a black base (instead of a green one); same result. The tiniest bit of reflection from the not-quite-matte black was giving us a teeny bit of spill, which meant grain. We figure we can disable the spill suppressor - doing so results in a bit of a green halo around the subject - and then clean up the rest with different keying tooks, choker mattes, etc. But we don't want to do it that way. The most recent shot took 20 minutes to animate. If it takes 45 minutes to key, that's an obvious problem. What we want is to pick our matte colour, and poof, have a passable result right away without touching a setting.
We tried using blue instead. It totally solved the problem. There was a teensy bit of grain in a test case wherein our foreground blue was very different from our background blue, and the foreground blue area was larger than it needed to be - we could have blocked it off to get a minimum of spill. But a proper test was totally fine. We like to do a few tests, to see where the threshold is for suckage. We're not toally sure why blue works so much better, but it does.

Here it is. Our first animation element. He'll be one of three elements. The animation ain't very inspired or great, but in this shot, he'll be almost completely covered by Johannes in the foreground. A good shot for practice and out-bug-working.
The keying is rough. Just for see how it looks.
We've been delving deep into greenscreening and keying. Not nearly as easy as we thought. That is to say, it looks good, until you look closer. I've found the answer to successful greenscreening; read the manual. Keylight explains all and in depth in the .pdf that comes with the plugin. It's pretty powerful software - you can key out some pretty heinous stuff with that thing.

A couple little colour tests. We stumbled on a neat HDR technique; altering the colour of the original three exposures. Does some neat stuff to the colour; in particular, it leaves brighter colours bright (like props) and sucks the orange out of the wood. These aren't great examples of this technique. But you get the idea.

The lighting sure is finicky. The HDR processing makes it more so. It's pretty much done, though. We're getting reasonably consistent results, and keep going back to the same set-up. It's not as simple as making it look good; there's other considerations too. A great deal of the backgrounds that'l constitute most of the footage will be just the back wall, up close. I've found that too much contrast in the back wall is distracting when you stick a puppet image in there. For example. We're also not really sure exactly how warm or cool the thing is going to be overall. Probably pretty cool. It's more evil.

On this one, I crudely photoshopped in some haze. I think I like it.

Gonna have to go back there and work on it with a real monitor.
