Thank you for the suggested work-flow, but I'm not sure I get the idea. Can you show an example? I'm using full scene weighted metering mode when shooting, so on most shots the sky is overexposed and the land is correctly exposed (or close to it). I'm not sure if your proposal can be used in this case. I can share a random raw file that I'm struggling to develop when using a parametric mask, so experienced users of DT can show their skill. :) Best regards, Teodor ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
