Just wondering if there was anyone able to shed light on this.

I have decided not to upgrade my Mac to the latest OS 10.8.4 as I do not like many features it has, as discussed previously.
So this means I can't update to theMac Camera Raw update to allow the Finder to show orf preview images.

But, I can get lightroom to work with and preview the orf files, so no issue.

I can get LR to convert the orf's to DNG, no problem.

But the DNG's from converted orf files still do not preview in Finder.

I thought DNG's were a universal format, but seemingly not.

Finder previews correctly other raw formats, that it supports natively, when converted to DNG's, but not DNG's from files it does not support.

I thought this odd as I thought DNG's were a 'universal' format

Your computer requires DNG Converter 6.4 for basic orf conversion through 8.1 for E-P5 & E-PL6 files. Version 8.1 will run on Mac 10.6 or newer.

Have the latest Mac/ Aperture/Photoshop Raw convertor, had not recalled coming across a DNG convertor too, will take a look when next home.

So I am guessing that means that DNG's are not universal then... all the same. I was under the impression that the idea behind these 'digital negs' was that they became a 'universal raw'.

DNG's are universal; the various types of raw files they convert are configured differently, thus the need for updating the converters.

They can''t be universal if converting from different raw formats to DNG produces different files.

Mac Finder can preview DNG's converted, in Ligjtroom, from Canon Raw or Panasonic raw, but not from Olympus raw.

If I convert 3 raw files, in Lightroom, one Canon, one Panasonic, and one Olympus, they all convert to DNG's, but Finder can't read or preview the file from the Olympus, even though it is a DNG.
Other software, like LRTimelapse recognises the Olympus DNG, but not Findet

Just home now and have checked..Yes I do already have the Adobe DNG convertor 8.1. But previously i converted from within Lightroom.
So i tried converting with the standalone convertor...and still the orf files do not convert so Finder can preview them.

Tried changing the Adobe Convertor preferences to be more backward compatible..all the way back to 2.4 and still files converted from Olympus orf format to dng are not pre-viewable in Finder.
Do the same test with Canon cr2 files and they are viewable in finder.

So it looks like all DNG's are nto the same ..it depends on the source raw file

Don't feel bad. My Windows 7 "Windows Explorer" won't preview RAW files out of my Sony. So I suspect it won't preview DNG either. Yet all my various editing software packages see RAW files with no problem.

DNG IS the universal format. It is the predecessor to proprietary RAW files which are based on DNG.
