The best bet would be to contact adobe and ask them to release camera matching profiles.
The more people ask them directly, the more they'll take note of it.
That has been done multiple times on Adobe bug report/feature request support forums. Adobe reps have responded but saying we are working on it. Until whatever issues between Adobe and Canon are resolved we won't see them.
You have repeatedly brought in Canon into this conversation. You know Adobe has been asked, and their response has never said Canon, and that they are working on it. Is there a reason for speculating that Canon needs to do something here?
Yes. Adobe needs information from Canon to be able to develop colour profiles. If they can do it for other manufacturers why are they not doing for Canon? Extended coffee break? Adobe released support within 3 weeks so it is not like they are sitting around.
As for PR no rep in a forum is going to point fingers at another company.
What is the source of this speculation? Do you have details on what kind of information is needed that only Canon can provide? In this same thread, I have seen one person claiming
anyone can make their own using a colorchecker to another claim of
it cannot be done without canon's help.
If you have details from adobe, please share. Else we all are good at speculating whether they are on a coffee break or are high with some other addiction. If not, let's just agree that we all don't know what is up, and adobe isn't giving us any answers.
Adobe's non-answer is the real issue - if it cannot be done without canon's help and they aren't getting it - a simple answer can be that
there are currently no plans to provide this. It will be an honest answer to a paying users' query and would shut all the secrecy and speculation and we can all move on. There is no need to point fingers anywhere. Why do users have to come defending Adobe with no one standing behind all this (which is pretty much what Adobe forums read like for all such issues)
