  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Meet Mr.T... in full 5k.

Nice shot, thanks for sharing it. Looks like it's got pretty low chroma noise, which is really pleasing to me. Can't wait to see more footage.
 
That is big! :)
It looks great Jared! Thank you for sharing!

Well about that dynamic range, one more stop means you get the sane image you are used to from R1 and you get an added stop to use for nothing but highlight handling, right? Is that something that would be "burnt into" the sensor or the way that the brain or RR handles the data? I guess it would be the codec... so either this image is underexposed to keep their progress protected (as it should be) or they are using the added range for the top end... I am no guru or remotely close to that... anyone care to comment on how off base or not I may be?

And about noise, I tried to mess it up to see noise and I can't see much at all... again, I am no pro grader, or DP or what have you... but this stuff looks clean... I suppose .jpg smooths it out a bit, same for saving my experiment, but it is clean as heck right? I say so cause someone mentioned de-bayering issues not yet addressed by Graeme and the other pixel guru guys. I guess that is the vertical and horizontal patterns, right? (trippy picture is a 1:1)

I need some gurus to analyze the picture for my amusement, even if it isn't one designed for nitpicking. I have no life atm and this is fun for me, so pour urself a glass of your fav and post something that will enlighten me or at least entertain me, pls. :beer:

I think of highlight headroom as a concept for film cameras, or video cameras with built-in nonlinear curves. With digital systems that are linear up to a hard clip limit, you normally expose for the highlights regardless of how much dynamic range the camera has. If you have one more stop of dynamic range, that means the darks are cleaner, so you have one more stop of latitude in post to push everything up (if you want) without noise becoming as objectionable as quickly.

As far as the demo image, their debayer isn't tweaked in yet so there are pixel-level grid and bar patterns; and even if it was, there's little point in pixel-peeping a heavily compressed JPEG image. I'd say just enjoy it for what it is.
 
I guess I also forgot about the 8-bit jpg thing which would not push as well as RAW... but although there isn't much to extract, I think the image speaks for itself anyway right?

It looks cleaner than R1, doesn't it? This IS a non-messed with image.

Meh... maybe I just better STFU and just pity myself for being an over exited foo' :)

Thanks jbeale!
 
From what I've read from people who actually understand the physics behind a silicon sensor (which is certainly not myself) almost all additional latitude is found in the shadows. So if it has one more stop of DR I would assume that's one more stop of sensitivity in the noise floor.
 
I think people are analyzing the Mr. T picture a little too much. It's a prototype image from a prototype camera. That aside, it does look pretty good. There's that whole moire or mosaic pattern throughout the whole image, but like they said, it's a prototype or beta demosaic on a prototype sensor... This is just a taste of what is to come.
 
Posting is good

Thanks for posting this.
The image looks spectacular!
Jarred, these posts are important. Pls keep them coming.
Actually, it would be great if you can add an extra 23 frames each second and post that...
Yeah, so keep us updated, thank you.

Certainly. Just to clarify, I am completely stoked with Mr.T in 5k and super stoked with hearing from Jarred and the rest of the Red team. I just didn't think it was something that needed clarification at this point. :beer:

Wow. Image quality and actual resolution seems improved alot from what i'm used to see on my R1, but i guess is both thanks to the sensor and thanks to the Red PRO Prime ... wonder how the same subject would come out with an R1 and the same prime, maybe would be a Red Primes seller test!

But wasn't the undisputed top concern with digital/RR vs. film the way that the highlights are handled, how they clip out so abruptly?

A linear digital image will clip to white harshly by definition. It's OK, it's the way it's supposed to be.

If there's enough dynamic range, you can make a nonlinear gamma curve that will compress your highlights any way you wish. Just like any given film or more. This is done in-camera with most systems, in the post production with raw footage like the RED.

I remeber that too. Those shots were amazing! Nature really is tough, it doesn't exactly take cues.

I really can't express how groundbreaking the DSMC is going to be for photography using stills pulled from a motion sequence. Currently stills photographers kind of have to anticipate guess or rely on dumb luck to get a really good shot. Soon they will be able to just frame the action, go back to the moments of significance and isolate the best of a stream of images. ALL OF THESE IMAGES FROM RED ARE PULLED FROM THE MOTION!!! Stills guys currently can do about 10fps, with RED we really are talking an exponential increase. The other hybrid cameras would allow you to do this at HD resolution at whatever type of compression that their video allows. That would be OK for some items on the web, but not much. (Note to RED: a plug in for Aperture & Lightroom that takes clips and arranges them in lightbox configuration would help)

When you couple that with the configurability of the cameras themselves you really are talking about something that changes the game. I almost always believe that the skill will always produce the better image, but this stuff is one of those things that just gives you more chances. So you could photoshop the group photo to get a shot where nobody is blinking or you could just grab the frame that works.

Tangentially if they are in a really great spot the could license an image to a number of different entities each having there own image.

Exactly, so I guess my question is if an under exposed image's histogram look like this one does? Jared said it was un-touched and it seems to have a very long roll off, or whatever the proper way to describe it might be.

I'd say it's impossible to make any conclusions of the dynamic range based on this jpg image. It's of a pretty low contrast subject, and the blacks seem to be crushed. I assume the new RED cameras will be able to cope with much more difficult shots than this.
 
Halsu is a free spirit.. often seen at hv20 forums.. be welcome man..

one thing for sure though.. when he will say it is.. you do not need to read the c.com pages.. ehehehehehe

edit
just kidding.. me'd prefer free spirits such as halsu..
my doubts on the c.com fanboys.. yeah fanboys.. not only red have them..
dislike fanboys anyway.. nice animal jarred btw.. we're safe.. no flowers over here lol
