I'll work on mirroring these as well @ www.red.ramjetfilms.com
All of thes files will start with greenscreen_ and will be followed by the actual filename in order to distinguish them from the other red images on my mirror.

Thanks for the heads-up!
I still think Jarred's shot had more soul :laugh:

But of course. Either way, it looks like somebody needs to update their CamAlign chart...
I can't wait to get back from work and toss these into shake.

Thanks link for the green screen series. It looks pretty good... but unless "one eyed jack" actually has a notch on the edge, it looks like a column of pixels is still missing, near the coordinate x=2937 in this image. Was this unrelated to the cable-runover issues that were fixed by a reboot?

That is some clean beautiful blue/green ... wow.

We have said that "Frankie" is tempermental. Primarily due to the crude cabling issues. It is a miracle that she has held up as well as she has given that she was really designed for lab tests and not extended shooting. We have learned to give her a break and appreciate all she is giving us. Our 1st real cameras go together in December. All this goes away at that time. We would ask you not to pick at "Frankie" too much. She is pretty sensitive.

I think all of us appreciate the chance to "peek behind the curtains" at these early development tests, which no other camera manufacturer would share, and I hope my observations are not taken the wrong way! These images are fascinating to see and of course I'm looking forward to seeing what Red can do when it's finished, as well.

Insert obligatory keying test:
Obviously no integration or compositing work, just a key. And what a beautiful key it was. Two clicks. The matte did need .8px of gausian filtration because of some de-mosaic artifacts though.
Given time, you could extract a perfect key. Then again, this is just about the simplest green screen test one could conjur up. David Stump said you guys shotmotion and fine hair... will they be posting that on sunday?

Unreal. Absolutely unreal, and this isn't even the prototype finished camera or software!
I'm curious about something- right after David Stump visited Red and before any of the Red frames went up, someone (Jarred?) posted a very low-res photo of the greenscreen setup- for all I know taken by a cell phone- but the green background was very vivid. Now, looking at the green screen images from Stump's session, the background is very different. Did the lighting change that much? Look at the comparative values of blue, in particular on background:
R,G,B values Left: (Jarred?): (65, 237, 1) Right: (Stump): (7, 224, 161)
The colors on the charts look reasonably OK on the Red test, so it doesn't seem possible that the background should be so different, unless there was a tremendously different lighting setup- like about 5 stops more blue on the background- when the right hand photo was taken.

I have heard about a "color matrix" in digital imaging systems, although I can't say I fully understand it. Is this something that happens in the Red camera somewhere between sensor-in and data-out? If so, does the color matrix have final parameters yet, or is it still in process?
Edit: To my surprise, I was actually able to manipulate the Red image at right to approximate the colors of the "snap", by using only Photoshop global curves & tweeks (not isolating any one color). So (in my limited understanding) it seems you could have this much difference just via a color matrix, and contrast curves. Interesting.
