DNG Previews in Windows Explorer Thumbnail

[Michael_S]

Sorry if this is a self-evident question.

Has anyone here used the Registry change to get DNG thumbnails to display in the Windows Explorer interface?  I assume they are the thumbnails generated by ACR or DNG Converter, so my ACR edits are reflected in Explorer when I update the embedded JPEG preview?

I want to know what to expect before I start Registry hacking.

Thank You,
Michael

Yes, though nothing unusual to expect. I have found some images weren't rotating correctly, but generally I don't look at image folders much with Explorer.

See Shaun Ivory's post - he's a software engineer in digital imaging at Microsoft. Also see earthboundlight which has a couple of registry files. As a caution, always open such files in Notepad and read what they're doing.

At least on Mac, you can do this with iView.  I have heard of a problem doing this to Canon CR2 files, where it made some applications unhappy to open the files.  I don't know if it got resolved, so I have not done this to my DNG files in large scale yet.

This is very much a Windows peculiarity rather than an iView problem. XP service pack 2 treats most raw files as dangerous and blocks their thumbnails, so users either need to change a registry entry or install Microsoft's raw file viewer. HTH.

And for what it's worth I have the Microsoft RAW viewer installed.  But it seems very focused toward Canon and Nikon raws (I'm a Nikon guy for now...).  It studiously avoids DNG.  Which technically seems bizarre.  Politically, it makes sense.  Why not stick it to Adobe?  MS hates being 3rd fiddle behind Photoshop/PSE and Paint Shop Pro.
