One Picture profile to Rule them All:

This week I had a 1DC for a job. I had enough time mimic it's color science and port it to the M5.

I had a 1DC an M5 the fabulous CN-E50MM T1.3 L (Canon cinema lens) so I took the same picture of a color chart with same iso, exposition and light conditions.

With the eos utility I matched the colors of the 1DC to the M5, so this is the result, you can use it an edit it any way you like:

You did not match the colors (not even visibly). You run an algorithm which knows what the colors were and just replaced them with the known numbers.

I'm sharing the original raws if someone wants to give it a try:

Cheers!

The pictures you are seeing are the jpgs, not the procesed raws.

The approch was number driven not empirical (the way it should be if you ask me).

As for the algorithm there is not such process, you have to sample color by color and do the math on each value.

This is an algorithm. The patches have a very limited range of spectral densities known to the software. The algorithm is to interpolate between them, and hopefully to match the colors in other situations somehow.

If you apply the 1DC picture profile to the M5 picture you get the same color results as if you shot it with a 1DC, that works for the color chart or the world...

No, this works for this particular chart in a trivial way - the colors are known. It would not work in all situations if there is visible metamerism between the two sensors.

Sorry I don't get your point... I have the habit of not getting in arguments with strangers on Internet.

This is not an argument. I am just telling you how profiling works.
