rfsIII: Am I misreading this caption: "This image was shot at the same nominal resolution but with red, green and blue information captured for each output pixel"
To me it sounds like the author shot the RG&B separately on a monochrome sensor (perhaps using colored filters as in olden days?)
And also, why the secrecy about which camera makers rotate their sensors 45 degrees?

@mgrum
No, Fujifilm never rotated their sensors.

forpetessake: They haven't mentioned RBGW CFA which are soon to come to the next camera near you.

RGBW, that's Banning's prior art, US 2,755,334.

Fujica: Wow wow wow, touting on X-Trans and forgetting to mention that it is much better in fighting moire.

There are advantages to bayer
So there are also advantages of X-Trans.

They each also have their disadvantage.
One is not really better then the other even though this post suggests so.

There is a lot of misconception of X-Trans and the problems of the past have mostly been resolved. Because indeed its more difficult to read out the sensor and there are methods needed to get the sharpening right. There is just a little learning curve to go through, because it is different.

Then on the other hand many people fall for the colours of Fujifilm... How come.

I know there is going to be a lot of trolling on this post.
But I am sure they never really dug into this matter - It will be mostly all hear say.

X-Trans is covered by Bayer patent ;)

mvmv: Hmmm… how about highlight recovery test?

@panos_m: " just because there are differences in camera light-meters calibration" -- yet another reason is when less green is allowed into red and blue channels (narrower red and blue filters in CFA).

Satyaa: I am not familiar with the Hassy or other MF cameras, and I am curious about the mode dial.
What is the Mq mode and the other two modes between 'P' and 'C3'?
I can't tell if that last one is movie icon.
Thanks.

Quiet, video, bulb, and 3 custom.

pcinhk: As the list of supported Raw cameras is the same as in FastRawViewer (http://www.fastrawviewer.com) it's my guess On1 may be using the LibRaw library.
FastRawViewer, is as its name suggests - check out their videos. it might give a hint as to what could be possible in On1 Photo 11.
LibRaw co-incidentally recently announced a new stable version on 21 April.

Current version of On1 PerfectBrowse is using LibRaw.

We have not seen On1 RAW yet, and can't tell if it is using LibRaw or not.

FastRawViewer is no indication of what could be possible with On1 RAW, we take no responsibility neither for the speed of On1 products, nor for any features / performance / stability issues.

krmuir: A bit disappointed by the results here - ISO 3M offered a little hope that a high ISO breakthrough was on the cards for those that really need it. As a user of A7RII ISO 100000 is completely unusable. I don't see much in the way of improvement here

@krmuir : with about 3 electrons per pixel at saturation?

The black level, starting from Hi 2, is completely uncontrolled. Linearity seems to be lost, too.

@Mike Ronesia : Could you please upload a sample raw file from CGO4? We would love to support this camera in FastRawViewer and provide you with a free license ;) My e-mail is ib@pochtar.com

@nerd2 : yes, myth. 1. read ISO standard. 2. compare raw data.

zeinali: Just looking at colorful jackets of four men, immediately you could find
some kind of process even at ISO-200 in RAW images.

@Barney Britton : Many thanks. We will add this compression scheme to LibRaw, will probably take some time to decode. Uncompressed files are already supported, also in RD and FRV.

@zeinali : you are looking at a converted result and making a categorical statement of what raw is, right?

EasyClick: This is a brilliant technology! It would definitely revolutionise digital imaging. Finally we can step closer to 'film look' than ever before. How long before Sony buys them up? (if they were smart enough) Then again, they might develop their own 'Quantum' film technology with some minor differences and rebrand it as their own. Any sensor development company should be smart and invest into those guys.

By the way, I don't see why the look should be referenced to Wes Anderson at all. It's quite the opposite, Anderson is trying to imitate the film look lost because of the crazy colour grading from Hollywood.

Well, for every sensor "response becomes non-linear as it approaches saturation". Problems are: this is unstable, and causes the skew of white balance; the fixed pattern noise jumps up, pixel non-uniformity becomes an important factor.

Some people explain it right, and some explain it wrong.

In reply to:

IdM photography: Lossy compressed RAW is NOT RAW... A RAW file must contain the unaltered data as coming out from the sensor. It's just unbelievebable that Sony could invent lossy compressed RAW files... I hope they correct this soon, and implement a lossless compression.

@sensibill : "They aren't a bit by bit readout of the ADC, after all. Never have been, with any camera." - Never say never ;)

Uncompressed lossless raw still is not what is coming out of the sensor, the sensor output is altered. And many of the alterations are welcome enhancements. Please see http://www.dpreview.com/forums/post/56430990
However, much depends on how one defines "sensor".
