An issue with Lightroom? I am trying to export some images that were edited in Photoshop from the Lightroom (ver 5.6) library catalog. The images are portraits against a pure white background that I created in Photoshop and have the RGB of 255 each channel in the info pallet.

But when I export the same image from Lightroom and then open in Photoshop, the white values then will drop to 247. I can't seem to figure out why as nothing different has been done to them in Lightroom.

Are any of you experiencing the same things? Is it just with the whites OR are all the highlights dropping at the right end of the histogram?

Any suggestions on how to avoid this issue in Lightroom?

Any help is appreciated.

Addendum: I just had the realization...thinking back, I've had this issue for a long time as there have been times when I opened images exported from LR, in PS and had to add an adjust curve to brighten it up. I just never questioned it until now.

What the heck, Lightroom! What's wrong with you.

If you are exporting from LR to PS using Ctrl+E you have an option - edit the original or the version with LR settings, so that may be causing discrepancies (e.g. if you edit the version which may not be pure white).

Another thing may be some color management issue. Remember that 255 or 247 have no color meaning without a color profile. So if for some reason when opening the image in PS you convert it to another profile, and/or when exporting from LR that may be causing different numeric values. That's in general.

My process is I shoot in Adobe1998 and then import into Lightroom. And if I export it from LR it goes as sRGB.

If I edit in Photoshop, then it does there as ProPhoto RGB and is saved as that in a PSD file, that goes back to the LR catalogue. When I export from the LR catalogue it goes out as sRGB



Here is what the image should look like
