Olympus High Resolution files and XnView
Posted: Tue Mar 02, 2021 11:11 am
Some Olympus cameras can take high resolution images. The highres mode takes eight images; using Image Stabilisation technology, it moves the sensor by less than a pixel between each of the exposure. It then combines the eight images into one raw / jpeg and creates a raw file that has higher resolution than a standard raw. The process writes three files to the camera's card:
The combined raw is written as an orf file and if raw+jpeg is enabled, a highres jpeg is also written - XnView lists both of these in the browser and displays a thumbnail. Both file sizes are much larger than a regular file of that type.
The first image of the eight is also saved as an ori file. This is a regular sized raw. XnView does not display the ori files when Settings, Custom, Images is ticked. I can force the display of the ori by adding 'ori' in to the include line. XnView now displays the file but not the thumbnail (at least, it uses what appears to be a default image).
Given that this is a newish feature of Olympus cameras I can understand that XnView does not support this file (I understand that the file is normal, it is just the extension that is not). Is this a candidate for a new feature request?
