OM-1 System camera raw

If you follow the steps in John Waller's link, you can get ACR 14.3 (the latest version) to work in Elements 2020.  You will also have to follow the same steps for Elements 2022. 

Note that the correct path for copying the plug-in file (Camera Raw.8bi) into Elements 2020 is:

C:\Program Files\Common Files\Adobe\Plug-Ins\Elements 18\File Formats\

For Elements 2022 it is

C:\Program Files\Common Files\Adobe\Plug-Ins\Elements 20\File Formats\

When will there be an update to support OM-1 System camera RAW files in Adobe Elements?

Is your precise camera model in the above list or is it a brand new model?

To help you, we need the precise model and your present Elements version.

The Elements ACR versions always come some time after they are available for Photoshop and Adobe never gives a date before the new version is ready and available.
