I use Lightroom 5.7 and I don't have Photoshop.
I've got a new camera (EOS 77D) and my version of Lightroom does not support it. So I was thinking of using Camera Raw to convert my CR2 files to digital negative files and then use the DNG files in LR. Is there a way to do that? All the online resources tell me to use Photoshop to do that, but I don't have Photoshop.
