Reverse Engineering / Re: Reverse Engineering Picture Styles

Yeah most of the options in NakedPSE are for exporting in various formats, which doesn't help us really decontruct the colour profiles.

FWIW I've found that, like with the R, G and B curves, any changes to the 3x20 matrices in NakedPSE will be lost when opening the profile in PSE and some severe changes in either matrix results in my test EOS R crashing. Still trying to find out the exact limits but it's a lot of trial-and-error. For now it seems like editing the matrices is not advised.
The good news there is I've gone through many premium profiles—about thirty now—and none of them have used custom matrices anyway. It does seem like every profile people have been paying money for over the last ~14 years has in fact been made entirely using regular PSE with nothing truly custom or out of the ordinary. Good news for those of us who'd like to know what changes were being made and how, since it's all much simpler than it used to seem, but bad news for those who paid money for a profile thinking they were getting some actually new functionality.

On the other hand. Picture styles seems rather meaningless as they are applied to 8bit h264. Better just dial in some visibly wider range straight in cam imo.
If your goal is only to push the latitude a little further for video and your camera doesn't have log, sure.

But for creating specific looks, this is a big deal. For anyone who needs to run-and-gun and use either footage or .jpgs straight out of camera, being able to now easily edit R, G and B curve values in addition to all the other adjustments that can be made in PSE could be quite significant. I have to keep a Fuji system on me alongside Canon as although I have a better lens selection with Canon, sometimes I'm asked to take some behind-the-scenes snaps to post right away and Fuji's Classic Chrome and Classic Negative profiles have so far been my most-requested looks for that. They're also the two colour profiles that are really unique to Fuji and PSE couldn't replicate before due to the lack of shadow tinting. With this NakedPSE and a bit of time (and ideally some way to get .PF3s working), that could well no longer be the case. 

We're basically talking about bypassing any need to shoot flat for later grading and just getting the finished, graded look done in-camera instead. It may not be 100% of the quality on pixel-peeping inspection, but for times when speed matters more than quality, this is (potentially) extremely useful.

Great timing. I read through this thread a year or so ago while looking for a way to access and hopefully edit the R, G, and B curves separately. Tried via hex as brought up earlier in this thread but couldn't get reliable results; probably more my limitation than the method itself, but anyway. Randomly got the itch to search again today and I'm glad I did. This NakedPSE gives quick access to the R, G and B curves separately. Signed up to the forum say thanks for bringing this to people's attention, at the very least.

What I've found so far is though profiles with edited curves work fine in-camera and in DPP, regular PSE doesn't reflect the alterations, and trying to edit the curves or most other 'hidden' things in NakedPSE and then editing the profile further in PSE causes the NakedRGB edits to be lost. Seems the only thing NakedPSE can change that PSE also maintains is the option to prevent a saved profile from being edited further or not. (And the basic sharpness, contrast, saturation and tone settings, but you don't need NakedPSE to change those.) Maybe I've missed something but it seems opening a .PF2 in PSE will essentially strip it of anything that wasn't edited within PSE itself. So you need to use NakedPSE to 'unlock' a profile, then edit it as much as possible in PSE, then open it up again in NakedPSE to mess with the 'hidden' parameters, or do it all in NakedPSE.
Additionally I've found that entering in any kind of negative or inverted curve, either in the RGB curves or the LAB curve, will cause DPP to crash when loading the profile; I don't know if a camera could take it but I'm not willing to risk it in a camera if DPP can't handle it. Seems every curve point has to be higher than the one preceding it. Whatever algorithms Canon uses to smooth out the curve can't handle it, I'm guessing. So no in-camera correction for scanning film negatives, I'm afraid. (Shame, since Nikon's editor can do that.)

Will be doing a lot of trial-and-error (since I don't speak Japanese) with every function for the next few days. Hope some of the more clued-in posters here can return to this thread and help 'decode' how much NakedPSE can do.

In any case, thanks again for finding that and bringing it to peoples' attention, this is potentially huge. Never thought I'd be able to get split-toned colour in-camera, but there it is.
