No. Simply export copies from LR using sRGB.
Keep the working space in LR and PS as ProPhoto RGB.
What I ment...
My colour setting for LR cc and PS cc is ProPhoto RGB. If I want to export my pictures from LR and place them on OneDrive, or watch the photo's on TV, do I have to export the photo's as sRGB, or can I export them and leave it as ProPhoto RGB? Is that colour setting suitable for OneDrive or tv?
Generally I would recommend sRGB, if images are to be viewed on TV screens or PC monitors. sRGB is generally the universal profile for photo sharing on the web. If you intend to share your images on one drive most people will see them best, without color shifts, with an sRGB profile.
So it really depends on your purpose. Are you using One Drive for sharing and viewing on devices or for backup and storage.
Thank You for your support.
For viewing on non color managed devices or devices that assume sRGB, then yes, sRGB is the right choice, ProPhoto RGB would look awful. That said, you might want to do a test and convert to Rec 709 (see: Rec. 709 - Wikipedia, the free encyclopedia) and compare how that appears to sRGB from the same image exported. You'll have to download an ICC profile for Rec. 709 for LR to use first. Again, since I doubt the device you're working with is color management savvy, that it would recognize and use an embedded profile of either, it might be worth testing because simply converting to each will produce slightly different color appearance and sRGB may be suboptimal.
Thank you for responding. Now I understand the difference . I understand your explanation very well.
Sorry for my English. I live in the Netherlands and to give you a good respond is a little difficult for me.
But, thank you for your clear answer. The matter is now clear to me.
