I would suggest that you download the FREE trial version of Photoshop CC with Lightroom . I think they give you 30 days free. It handles DNG files with ease. Unlike most of the members of Mavic Pilots, I actually do pay for and subscribe to the entire. Adobe Creative Cloud suite and have full access to every update, which is actually almost weekly. I have been using the latest versions of Photoshop for years, and the advantages of its great new masking tools for editing any single part of my image such as sky, foreground, people, faces, eyes, or a dark clump of trees in the image. If you like it, you can get just the Photo suite for about $10.00 a month. I know I will get the usual blow back on Adobe for this post. I will ignore it.I've been shooting DJI DNGs for three years with the Mavic 2 Pro. Now I've started with the Mavic 3 Classic. I experienced very satisfying results processing the M2P DxO, first to convert the image to tiff, then into Lightroom or Photoshop. Always great results.
I will add that LR is LR6 (very old) and PS is CS5 (also very old). DxO is Lab2, all older versions (without subscriptions).
Now with the Mavic 3 DNG, I can only use Adobe Camera Raw to start the DNG process and get the image into PhotoShop. For some reason, ACR6 will open the DNG, but unsurprisingly, PS CS5, will not . Neither will DxO for the Mavic 3 DNGs. The M2P DNGs will open in DxO. But, with all this the eventual movement of the Mavic 3 DNGs though ACR and into PS CS5, then to LR6 (laborious), ends up producing very poor results. I find the sliders in LR6 producing very little affect.
DJI did something and it's not good. Something changed with the DNGs between M2P and M3C. I'm going to try the DxO Pure Raw 30 Day trial to see if this will address the situation.
As others have commented, the jpg images are FAR Superior to what I can produce from the M3C DNGs. The Mavic 3 Classic is a great FLYER, but the still photos using DNG are very disappointing.
If you give it a try, you will then have your answer and you can then decide if it is worth it to you.
