Interesting Question about D2X sensors

Do you know where I can download sample RAW files?

Drop me an email so I'll have a valid address, and I'll get you a couple.
I use DNG and delete the NEFs but I can take a couple shots and put the
NEFs somewhere for you and send you a download link.

Prey tell, Brian, how do you (intentionally) manufacturer a sensor with
different sized photo receptors?

Talk to freaking Fuji about that.

As for what you MEAN (how do you make a dual mode CMOS sensor), it's
relatively simple given the nature of CMOS technology. You can process
the pixel individually so it's pretty easy.

12.8 megapixels uses the ENTIRE sensor.

The 6 megapixel crop mode uses a center portion of the sensor.

It isn't ****ing rocketry, you ingrate!

Is what you're looking at the same as the TIFF CFAPattern? If so, 3
would be cyan. However, according to the metadata in my DNG files, the
CFA layout is given as 0,1,1,2 (R/G/G/B), suggesting a standard layout.
But if the values you're talking about are something else, I'm not sure
what to look for; the difference could be in the color matrices.

It could also be that every other green has a different sensitivity.

Is it possible these are masked edge pixels and just labeled weird?

Nikon are going to great lengths to explain how they capture 12
megapixels of data with their new "dual" sensor in the D2X. They are
describing their sensor's photo collector points of the newly released
Pro D2X cameras as being 2 different types/sizes of collector points...

Sigma did the same with their Foveon sensor SD9 cameras. I think because
Nikon collect RGB data from each site, they cannot be lumped in with the
Foveon "invention" of sensor size. Just the same, the Nikon sensor is
different from a traditional bayer sensor as we know it in a Canon
camera. How different is not as clear as it should be.

We are aware that smaller photo receptors have their own unique
problems. Is using two different size receptors in the way inkjet
printer makers get nicer looking images by using different size droplets
of ink, have Nikon discovered how to make a high resolving sensor in a
small size?

So here's the question of the day for thinking people: How many sensors
are in a D2X Nikon to achieve 12 megapixel images? Careful now... It's a
loaded question!

I know a few D2X shooters who couldn't give a rats arse as to how Nikon
do whatever they do to get the pics. They simply use the cameras for
(gosh!) taking pictures.

But anyway, this is not related to pixby/Douglas' delusion that
the D2X interpolates from 6Mp to 12Mp (grin).

Which is verifyable with a resolution test target, if one has a doubt.

I don't think so. The pre_mul[] values are for light-collecting pixels.

Why are you participating in a discussion that doesn't interest you?
Are you a masochist? A control freak?

Strange. If the sensor had an extra (or different) color filter, I'm
sure the marketing and PR guys would be trumpeting it.

I'd see what's going on with it, but dcraw.c is a bit thick for me. I
can write C code, but I am not good at reading other people's,
especially when it has grown the way dcraw.c has. What would be a lot
easier is just having a D2X NEF of a gretag-Macbeth color checker.

They were for the last 6 months or so in every magazine ad I saw.
