Hi this question is specific to DNG converter and its options (didn't want to make the subject a paragraph) I'm using an older version of Photoshop (CS actually) and it tops out at ACR 2.4 ... at work I use CS6 which has a later version of ACR. I noted when I download the latest version of DNG converter (hadn't needed to upgrade in a while) that it allows me to pick which version of ACR to save my DNG file as. So, aside from stuff like "lens corrections" database (and perhaps embedding properties) are there any differences in ACR as the DNG converter? I've tried making them 2.4 or 7.1 and my ACR opens them fine. So does anyone know what's different?
