Well, yes, Philipp, now you are referring to metamerism (the bane of my prosthodontic life ) There is very little that one can do to counteract it.

It also renders all colour temperature measuring apparatus not very effective in real life.

But then, there are very few things which reflect colors of single wave lengths; practically everything reflects a rather wide spectrum of light, with some bumps and gaps. While it still might be possible to quantify that, it would not be as straightforward as you seem to imply.

 

That's a good point Philipp, though in creating a camera profile I would imagine they are dealing with the measuring of pre measured colour swatches (?) And I never meant to imply it was simple! Working with limited colour space of a digital device it must become difficult and combined with the gaps you rightly speak of even more so. Though my original point was that infact, colour can be measured by numbers.

 

In terms of this on a human level, we do have 3 separate cones in our eye. One for the R spectrum, one for the G spectrum and one for the B spectrum so we have evolved very well to differentiate the visible spectrum at any one time as such. We even have the capacity to fill in the blanks with complementary colours which don't even exist in the spectrum such as magenta.

For me 'true color' does not truly exist.

Take for instance the difference between the appearance of the M8 JPG and the Capture One rendition of the same RAW: the direct JPGs have a different rendition, to me it is sort of blended towards the Holmes saturation with a slight golden tinge.

On the other hand the direct JPG is a bit in the direction of the Japanese, such as Canon, direct-JPG, these are even greener. The directJPG from my M is not as green though as the old Fuji film colors (Japanese style).

Now personally, I think the directJPG renders beautifully on a print even it is 'too green' on screen. As such I tend to prefer the direct JPG above the C1 rendering; alas with JPG I have a lossy image I cannot change anymore. So I have to stick with the second best (third best?) rendering of C1.

Many acclaimed the CCD sensors as having a color rendition close to the KODAK Velvia films.

Now if the new sensors have a better 'true color', [than standard delivered by the Japanese-style CMOS toolbox rendering], then I expect it would again try to move in the direction of the [what I call] Kodak-style Velvia smooth colors.

 

Alas we will be stuck with the likes of C1 staff who pick their own balance again on the new sensors ; and that certainly will differ a lot from the direct-JPG that Leica staff will work on.

If you dislike the default profile of C1 just put in your own, or even simpler, put in another default.

Velvia is a Fuji product, not Kodak.

I know how to do this [thanks to Jamie Roberts who had a link to own and Holmes profiles], but where are other currently available profiles? Several years ago I used a Holmes profile occasionally.

• What happens if I switch to LR?
  

Does LR give a more balanced rendering?

Sorry for being OT though.

Oops .

[Leicafanatics]

The real interesting bit of this interview.

 

totally agreed..
