JohnThere’s a relatively inexpensive app for the Mac called GraphicConverter by Lemke Software. My macbook opens every file FINE, but cant convert them, my macbook is 10+ years old FYI.

How does that happen? photo taken with Pentax camera and Pentax software wont open them. I cant seem to find any program to actually open the photo file now ! I installed the Program that came with the camera, and it wont read ANY of the files, says they are all 'not supported'. How do I batch convert a lot of DNG files on Windows, or Mac for that matter? When I get better at photography, I imagine I will use that tool though. I dont use Lightroom like everyone else does, it seems. I have used the DNG and JPEG since starting shooting, I usually use my Macbook or iPhone to open the DNG and edit. Thanks everyone for the replies! I will look into the ideas and see what I can figure out! John I didnt honestly think about putting the card back into the camera and tell it to convert, although that surely will take a while. But the problem happened when I was encouraged to try just shooting DNG/RAW images,(which is why I have a couple trips wrth of photos I want to convert.)Īnd I have tried the DNG, and PEF, all the settings in the camera, with no luck on opening them anywhere. Its a couple trips that I took pics on that I have not been able to 'publish'. I don't use the Pentax software but perhaps it only works with Pentax native raw system. Why not just stick to jpeg from the camera ?ĭNG files are not actually 'photo files like.

I can't imagine your iphone can do as good a job of raw converting a DNG file as software on a computer or your camera itself.
