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.

@Mike Ronesia : Thank you, files are downloaded.

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

agentlossing: My takeaway is that underexposing to -1.7 EV is too much for this sensor, as in the waterfall pic. Slight underexposure is fine, however, and detail retention is pretty impressive. Lens appears to be fairly high-resolving, details aren't super crisp but you can tell they would stand a fair amount of microcontrast adjustment.

@Barney Britton : Point is, DR400 has nothing to do with actual exposure. Lack of diagnostics for raw exposure in the cameras is the problem.

@kolyy : The underexposure on the waterfall shot is 2 stops before the highlights start to blow out.

@Barney Britton: it seems the camera emulates ISO 800, because the raw data numbers correspond to ISO 200. Means effective underexposure is about 2 stops before the highlights start clipping. Tags say that the meter calibration is -2.72 instead of Fuji regular normal -0.72.

@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 ;)
