Adobe DNG converter

I was surprised to find that the Adobe DNG Converter for Windows will convert DNG files to identical DNG files
e.g.,
A.NEF -> A_1.DNG -> A_1_1.DNG etc.

Ending the program leaves the folder settings unchanged, so that on startup if you click "Convert" then everything RAW in the named folder is batch converted again including the DNG files.

All of them will allow extraction of the original RAW file if that option was chosen.

Yeah, I found that out last week too. That should be a fairly easy fix, but I guess it’s still in trial phase anyway.

What is the problem with this behaviour? (As far as I know it is designed to work like this).

Although it is presumably rare that you want to run DNGs through the Converter with the same options, it becomes useful if you run them through with different options. Here are some examples:

– Change from compressed DNG to uncompressed DNG, and vice versa.

– De-mosaic a DNG file that hasn’t been de-mosaiced. (There isn’t a vice versa in this case).

– Remove an embedded original Raw file, if you want the smaller, basic, DNG.

– Embed an accompanying XMP sidecar into the resultant DNG.

The way to think about it is to remember that a DNG file is itself "simply" a Raw file.

(I’m not sure what this "trial phase" is? The DNG Converter, all versions, have behaved like this for nearly 8 months, if I remember correctly).

Thanks for the info.
I know now to keep the NEF’s & DNG’s in separate folders 🙂

The "problem" is that you end up with three times as many fiiles as you should have, if you do it on accident. You have the RAW files, the DNG files from the original conversion, new DNG files from the new run, and DNG conversions of the first DNG files.

It’s not a world-destroying crisis, it’s just annoying.
