“I don’t use Adobe Camera Raw, I use Lightroom and then Photoshop.” Sometimes I use DPP to convert from CR2 but any time I have used Photoshop or Lightroom with a CR2, the first thing that opens is Adobe Camera Raw. It is what does the conversion from your raw file.
I hardly ever bother with DNG. It is just another format. I like the file the way the camera made it.
