I have exactly the same post-processing workflow with the TG6 and the OM10; both provide RAW, both go into Lightroom. Have I misunderstood your comment?
I'm going whale snorkeling on the Silver Banks of the Dominican Republic. Rather than lugging around my OM10 in a Nauticam housing with a WWL-1, I've desided to use my TG-6/Olympus housing with a Lraken KRL-02 wet side angle. Any hints for this combo? Will I need to burp the lens once in the water?
