Is Art Filter metadata stored in Olympus raw image files?

A visitor to my youtube show and tell of Olympus Viewer 3



asked how he could find out which Art Filter was nominated in the camera in a raw file and whether it could be applied in bulk to other raw files. I was puzzled by this and had to make a fresh raw file from my E-PM2 (it was handy) to verify my response. Indeed,

1. Olympus Viewer 3 does not display which Art filter was applied to the raw file.

Note that the Art Filter is not pre-selected by Olympus Viewer 3 even though the EXIF Makernotes metadata stores the info


2. The Art Filter *is* stored in EXIF metadata in the MakerNotes category in the tag ArtFilterEffect (shown using EXIFGUI / EXIFTOOL third party software)


The name of the Art Filter is stored as text but the but the parameters of the secondary adjustments is not labelled in text, just numeric codes.


  1. You can find out which Art Filter was selected in the camera when you look at the EXIF of the raw file.
  2. You have to manually choose this Art Filter in Olympus Viewer 3 yourself.
  3. You have to manually choose the secondary variations yourself.
  4. There are two alternative workflows if you want to apply your Art Filter to other raw files, 

Workflow A

    1. Select the Raw Development Module by clicking on the RAW icon in the toolbar.
    2. Choose the Art Filter manually and the secondary settings manually.
    3. Save the raw develop settings as an .ORS file
    4. Select raw file one by one and nominate that Raw Develop Setting to apply


Raw Develop Settings in the Raw Edit Module of Olympus Viewer 3

Workflow B

  1. Instead of the clicking on the Raw icon in the toolbar, click on the Edit icon in the toolbar
  2. Choose the Art Filter manually and the secondary settings manually.
  3. Choose the menu Edit > Copy Edit Settings (Ctrl+Shift+C)
  4. Choose other raw files in the thumnail strip in the toolbar - choose the first one you want then Shift Click the last one or Ctrl+Click each subsequent one
  5. Choose from the menu Edit > Paste Edit Settings (Ctrl+Shift+V)
