If i check Preferences > XMP > Exposure, Contrast, WB - Force Adobe software to match FastRawViewer brightness (exposure) only thing happening it sets exposure -40 in Adobe Camera Raw (exposure set to 0 in FRV), other settings in ACR are not set changed.
I expected FRV allows to set custom baseline exposure 0.35 so total exposure would be -1.35
also
Contrast = -33
Black = +25

Yes, 'Force Adobe Software to match FastRawViewer brightness' will add (usually) negative correction to Exposure to compensate Adobe hidden exposure correction. This setting is intended to work for 'Forcing Adobe tools to render tones accurately' as described in the application manual: https://updates.fastrawviewer.com/data/FastRawViewer2-Manual-ENG.pdf#pag...

>Forcing Adobe tools to render tones accurately
Followed this section of user manual and now it all works.

Instead of EV -0.40 i'd like to use EV -0.35 as its the setting from my camera, how can i do it?

the 'Force Adobe software...' setting results in writing 'negative' of Adobe's hidden exposure correction (negative BaselineExposure in DNG tag terms), not your camera settings.

If one want to apply some standard exposure shift for all opened images (if no XMP sidecar with recorded exposure correction exists) one may use Exposure correction on file open: Autoexposure and fixed shift in Autoexposure settings.

> open the files where you want the new settings in FastRawViewer and at the Bottom Bar change the White Balance or Exposure; clicking twice on "Exposure correction on/off" to switch it off and then back on should do the trick.
This causes slight glitch when i click back on exposure setting it sets to 0.00 EV however after switching to next image and going back i find image set to -0.40 EV would have been great if it set to -0.40EV right away.

>"Force XMP files creation" (Preferences -> XMP - Force XMP files creation for
RAW files) and open the files where you want the new settings in FastRawViewer.
There is also glitch with this option enabled when opened folder with RAW files without any XMP files and scroll trough them using keyboard right arrow, until last file i scroll back with keyboard left arrow and i find some files are set to -0.40EV some files set to -0.80EV others to -0.120EV others set to -2.80EV there seems to be some bug in the programming.

Please provide:

  1. Set of files to test
  2. Copy of your settings/preferences (Windows: use FastRawViewer backup script; Mac: provide your .plist file)

Without this we do not have enough data to reproduce the problem.

Here you go https://www.upload.ee/files/15182830/FRV-backup.zip.html
you got to enable "Force XMP files creation"./

Thank you. File downloaded, you may remove it to clean space.

Please change Preferences - XMP - Exposure, Contrast, WB - Preferred XMP tags for Exposure/WB to either Flexible...  or (default) FastRawViewer

That fixes it, thank you.

How about setting -0.35 EV instead of -0.40 EV?

Another issue i noticed is when Apply Adobe hidden exposure correction is unchecked, Thumbnails shown in Image Grid mode does not reflect this setting, still showing old way. Is it because thumbnails loaded from embedded JPEG?

Yes, thumbnails are loaded from embedded previews (or external JPEGs)
