That's a big help, thank you. I was able to complete one. I hope there are plans to update the tutorial because I still don't understand some of the other functions, like what type of output to choose, and if that has changed with the updated software. And whether I should go with Tone Mapping or Exposure Fusion. I have much to learn, including masking. On my interior shots that include good exposure for the interior, but blown-out windows, I really want to be able to preserve the good bracketed exposure I have of the windows, and I suspect that may require masking. (The final is closer to correct now, but the windows are still overexposed while in the source shot they are not.) But I think I'm in business, for now.
