EricM Posted July 9, 2014 Share Posted July 9, 2014 <p>The mental gymnastics are insane. No once cares if you're the fourth here to use 7.1 and come back with a slightly larger dng. Arron has gone to the trouble of uploading the file so how about just playing along nicely and using Camera Raw 4.6 like Aaron and I have, and see if you can also achieve a massive 77.3MB dng like we both have?</p> Link to comment Share on other sites More sharing options...

So we've all varified it works as it does. Arron's trouble of uploading was well served and I'm glad I asked for it. If you or Arron is unhappy with how an older version of software operates you can upgrade as you yourself advised (and I agreed with) or stick to the same behavior, now knowing what an upgrade path <em>could</em> provide. </p> Author “Color Management for Photographers" & "Photoshop CC Color Management" (pluralsight.com) Link to comment Share on other sites More sharing options...
will_perlis Posted July 9, 2014 Share Posted July 9, 2014 <p>I'm not sure what the point of beating dead pixels is, but I get a really big file with 4.6 and one around 20Mb bigger if I include the original RAW in the DNG. Adobe changed the compression algorithm, that happens.</p><div></div> Link to comment Share on other sites More sharing options...

NEF produces three sizes (if not more) of DNG <strong>depending</strong> on converter version and setting.

cameraart Posted August 8, 2014 Share Posted August 8, 2014 I use a Sony nex-7. My .awr file size is about 20MB. Converted to .dng is about 90MB. I can't figure it out, either. Link to comment Share on other sites More sharing options...

So it's pointless to use version 4.6 instead of 7.1 with a modern version of a raw converter that understands DNG. </p> Author “Color Management for Photographers" & "Photoshop CC Color Management" (pluralsight.com) Link to comment Share on other sites More sharing options...
cameraart Posted August 8, 2014 Share Posted August 8, 2014 I think I'll probably just give up on DM G conversion. Who the hell cares of my files don't last 50 years. Link to comment Share on other sites More sharing options...
EricM Posted August 8, 2014 Share Posted August 8, 2014 <p>That's a great thought, Lionel. It's time consuming, assures nothing in the archival scheme of things, and now it's not even saving of hard drive space.</p> Link to comment Share on other sites More sharing options...
cameraart Posted August 9, 2014 Share Posted August 9, 2014 Since Adobe states that DNG is open software, (anyone can alter it), why hasn’t anyone fixed this problem? I believe Adobe is trying to crowbar us into buying the latest software, which means more unnecessary expense. I won't use DNG to store files, just convert my raw files (AWR) so I can open them in ACR, edit them and save as TIF. Then delete the DNG files and keep only the AWR files and the TIFs Link to comment Share on other sites More sharing options...

You <strong>don't</strong> want to buy new software, convert to DNG. Use the proper version of the spec too. You <strong>don't</strong> want to use DNG, update your software. OR how about complaining to the company making the raw file different each time such new software is needed to read that raw? </p> <blockquote> <p>I won't use DNG to store files, just convert my raw files (AWR) so I can open them in ACR, edit them and save as TIF.<br /></p> </blockquote> <p>Fine.

cameraart Posted August 10, 2014 Share Posted August 10, 2014 I used Aaron's file and the converted file for ACR 4.6 was 81.3 MB My file from the Nex-7, AWR, 20MB converted to 90MB DNG It's the ACR 4.6 that's the problem.

When I did the test using DNG converter 8.4 with DNG version 7.1, I didn't get an 81MB file, the DNG was about 4MB larger than the original. Are you saying you can't use version 8.4 for some reason?

What's ACR 4.6 (which is really, really old) got to do with converting the raws to DNG using DNG converter 8.3? Are you saying ACR (which came with CS3) can't deal with a DNG using 7.1 spec so you moved back to an older DNG version? </p> Author “Color Management for Photographers" & "Photoshop CC Color Management" (pluralsight.com) Link to comment Share on other sites More sharing options...
cameraart Posted August 12, 2014 Share Posted August 12, 2014 No. I used DNG Converter 8.3 as well as 4 other versions. Using any DNG Converter and making the conversions compatible with ACR 4.6, the file size goes from 23MB to 90MB. Go figger! I use CS3, and it works just fine. I won't upgrade to CC. I must keep my fixed costs, (overhead), down. (Retired professional photographer.) I'd like someone to fix that software, but I can live with it, knowing its weakness.
