Usually, when we want to get best color for photo from canon R3、R5.., we use

Digital Photo Professional and save them as .tiff _16. So that we can add them in lightroom workflow. The problem is .tiff is too large. Is that possible the lightroom can load .dr4? ( configuration file from dpp for every picture ,like .xmp)

Have you tried changing the raw default in Lightroom to "Camera Settings". In classic this is in settings->Presets), in Cloudy Lightroom it is in Preferences->import. It should make the right after import rendering very close to the DPP rendering. The default setting of "Adobe Default" has very blah color rendering that always needs some attention to make it more alive. Camera Settings applies most of the settings (profile and such) that you might do in camera and that software such as DPP picks up on. I don't have these cameras but for my Nikon Z series images this makes the rendering out of the box close to indistinguishable to the in-camera jpegs or those from Nikon's software and objectively much better quality (acuity, etc.).

I've wondered for a while what other settings, beside the profile, are applied by LrC when Camera Settings is used as the default, so I've just done a quick test. In camera I changed the settings (for Sharpness, Saturation, Color Tone, Contrast) of the Camera Standard "picture style" from the default to the extreme. Took a couple of pictures from my desk, reset those settings back to default, took a couple more pictures. On import into LrC using "Embedded Previews", the difference between the two sets was, as expected, obvious. However, when switching to Develop, thus getting Adobe's version of the raw files, there was no difference between the two sets, i.e. LrC is only applying the basic camera-matching profile, and does not apply any adjusted related settings. I would think that DPP would respect those adjusted settings, but I'm probably not surprised that LrC does not.

But that was an extreme, therefore unrealistic, test for most users. I agree with your main point, using Camera Settings will likely give quite a close match to the DPP starting point in most cases.

Thanks for testing @Jim Wilde . On my Z7 it does read all these values including changed contrast and even the HDR like modes. This might happen because Nikon actually puts these edits in the file as camera raw commands too and not just their own proprietary metadata. Didn't know if this was true on Canon. I do know that at least the profile gets read by Adobe on Canon cameras. Since almost nobody changes any other settings that might be enough.

If .dr4 is like an xmp sidecar, then importing it in Lightroom would be pretty useless anyway if that were possible. The sidecar file probably contains the non-destructive edits that DPP makes on the Canon raw file, but because these are proprietary, Lightroom would not be able to do much with them. The result would almost certainly be different from what you saw in DPP. So using DPP 'to get the best color' would fail, because that color would be different again in Lightroom.

I doubt that very much. I assume you've tried to import a raw file with the adjacent .dr4, with what result?
