'4K for Real' screen grabs

Dalsa has posted full-resolution screen grabs from Origin, their 35mm single-sensor 4k camera. It uses a CCD instead of CMOS, but can we assume these images are a pretty good preview of what we can expect from Red?

Not so. Dalsa uses a single CMOS bayer pattern 4K sensor.

I wasn't sure; all the information about the sensor mention both by way of comparison. Their Sensor Architecture Whitepaper concludes with this:

"DALSA has designed leading-edge CCD and CMOS imagers for 25
years. Given the demands and limitations of the situation, we
determined that the best imager design for our purposes was (and
still is) a frame-transfer CCD with large photogate pixels and a
color filter array. It is not the only design that could have
succeeded, but it is the only design that has succeeded. "

So that is what I based my statement on.
 
oldenarm: I went to the Dalsa site. I see how you got that impression. In fact, now I'm confused. It was always my understanding that it's a single CMOS sensor. Now I'm not so sure. I have read everything from a single CCD or three CCDs and one CMOS. The Dalsa site shows a single sensor and I recall discussions elsewhere about Bayer pattern CMOS. I'll have to investigate further. In the meantime, I apologize. You may be right. I'll be back!
 
fuzzy at full resolution :(
(at least the butterfly imagae)
hopefully Red will be clean & clear...:dankk2:
peace

If you only download 1 pic, download the Dalsa western footage pic, which looks really nice, clean, sharp - and it's even a 4K 48bit TIFF :-)

The sample 4k images from Dalsa are so disappointing.

First of all, I don't see the point in putting out only color corrected images, since it's the RAW log files that are more important and people like me want to play with.

The images overall are poorly shot, the girl and butterfly are way too soft.

The western scene has too much noise, and I noticed it right away. Since I don't know what the raw image looks like, not sure if it's poor color timing, some post enhancement or inherent in the capture.

I hope RED gives us both color corrected and RAW files to look at.
 
I've been following the Dalsa for a long time (before I knew the price would be $3000/day to rent) and was happy to see they finally posted some images from their camera, even if they were already treated (color corrected, etc...)

I don't know if it's fair to expect the same image quality from a camera that costs $$$$ (dalsa) to a camera that could be purchased after six days of renting the Dalsa, but in the least we have an example what a 4k image looks like, which is exciting to me.

I am definitely looking forward to the RED, especially knowing it has a higher resolution than the dalsa. (not that I would be able to use 4k any time soon, but...)

Anyway I think the Dalsa screen grabs look good and is good encouragement for the RED team.

that's my two bits anyway.

I happened to be at the Montreal film festival in the fall of 2004. Dalsa had a 2k prototype of their camera and a short film shot with it. The film had interior and exterior footage shot by four DPs with both the Dalsa and a 35mm camera. They projected both versions of the film, sorry I forget if the Dalsa footage was a 35mm transfer or an HD projection (probably 35mm), however the Dalsa footage was beautiful, I remember some of it wasn't quite up to par with the 35mm, but mostly it was. This of course was a 2k prototype and a Dalsa promo reel, but certainly promising. Of course nobody may ever use the Dalsa if the Red comes out soon enough and fulfills it's promises.

Cheers,

I think I remember reading about that. Wasn't the short film called "The Glove" or something like that?

I remember wanting to see a frame from the short, but wasn't able to.

Either way the RED won't help sales or rentals for any of these high end Digital Cinema products (Panavision Genesis, Dalsa Origin, Arri D-20, etc...) if it fulfills expectations.
