Hi Doug,
I think you misinterpret this poll a bit. I admit that the title of the poll is a bit misleading.
But, some folks are saying there is a typical MFD color that say the X1D posesses, while the GFX has typical DSLR color. Those cameras use the same sensor even if it is conceivable that they may have different CFAs. Or, maybe not as folks using the X1D with Capture One seem to get very good results.
The intent here was to see if folks recognise MFD colour, if such a colour exists. I would assume that my P45+ would have MFD colour?
Obviously a lot happened since the P45+ and the Alpha 900 were released. The P45+ was from 2007 and the A900 from 2008. So in a sense they are same generation. In another sense the P45+ is proven CCD technology and the A900 is Sony's first full frame CMOS sensor.
Some folks argue that CCD colour is superior to CMOS colour. I don't think that is the position that Phase one has now.
I have also include a lime in the setup, as you indicated that the limefruit has a very high near IR content. Which it indeed has:
So, I asked myself if the high IR content in the lime would cause a yellowish cast on the limefruit. This was not the case with the three cameras tested here. They all reproduced the limefruit extremely well.
The color patches shown above were inserted in the picture on a layer above the lime and blended in "color" mode, that keeps L channel from the base image but uses the "a" and "b" channels from the sample. The patches are not visible in any of the images, so match is virtually perfect.
This comparison is of course limited to what I have here. If you arrange with Phase One to lend me a Thrichromatic over a few days, I will gladly redo the demo.
In this demo I wanted to eliminate raw converter as a factor. In engineering you try to eliminate as many variables as possible. Here I used a tool developed by Anders Torger that is based on pure and honored math, that treats all sensors similarly.
I could have used C1, but C1 has another tone curve and I am pretty sure adds quite a bit more saturation, so, I would need to correct for that manually.
Or, I could have processed all images in C1, but I doubt that the image quality professor spends the same effort on an oddball Sony product, like the Alpha 900 as on the P45+, not to mention the Thrichromatic.
As things are, I can use Capture One with my P45+, as the MFD version is free and that also applies to Sony. But, I prefer to pay for a subscription to the Adobe product. I think that photographers own their images and can use whatever raw processor they prefer.
There are some reasons I prefer Lightroom over Capture One:
- LR has content aware handling of highlights and shadow, maintaining local contrast. Capture One doesn't have that.
- I prefer DNG over natives formats. Capture One has not supported DNG for a long time and their support for DNG may be halfhearted.
- Both DNG format and DCP profiles are well documented that is not the case with C1 colour conversion pipeline.
- I prefer to use my own profiles.
- But, that is just me, I like to have freedom of choice...
Regarding the Thrichromatic, Jack Hogan did a very trough analysis of the sensor, just based on a few sample shots, from yourself and Dave Chew. He found that the Thrichromatic has some significant advantages. His analysis is published in three chapters:

Sharing good and honest info is not a bad idea.
And just to say, Jack likes the Trichromatic.
Best regards

By making profiles for each camera and then processing them in Adobe software you've robbed the Phase One of one of its core assets: that the same company makes the lenses, camera, software, and color profiles. All components are designed together for the best end results.
It's like you've taken a ready-to-race dragster and stripped it down, replaced the tires with generic tires, replaced the chassis with a square block of metal, and put in low-octane fuel. And now you're running a test on the engine versus other engines. But the engine wasn't designed to run on its own; it was designed as part of the overall car.
Also notably this back is from 2007. The improvements Phase One has made in the 11 years since are also pretty profound. The Trichromatic has the best color of any camera I've worked with (in my highly biased and subjective opinion).
