Four Figures

Slow CPU style HDR: Luminosity masks on JPGs. Taken in the Duomo (Cathedral) of Orvieto, Italy.
I always face a dilemma when trying to capture in varied lighting, but you have done it well here. I'm not sure what Slow CPU style means, though.

@jyokota Thank you. Sorry for the delayed response. I spent 1 Dec with last minute trip preparation, the 2nd and 3rd in transit, and today in jet lag.

HDR apps and tools consume copious RAM and CPU cycles. My travel netbook would be painfully slow. Instead I: 1) Extract Jpgs from the Raws, 2) Use luminosity masks to select non-blown out highlights from one of Jpgs, and select detail in the shadows from another of the Jpgs, then 3) Use those masks as layers on the Jpg that was exposed so it has both non blown out highlights and loss of detail in the black areas. Result is an HDR image that many (but not on 365) say isn't one because it doesn't look like one.

If I like the result, I'll recreate it with the Raws using a HDR app on my home PC.

@fotoblah -- thank you for the explanation! I only had my Sony bridge camera in Italy and in Russia (I take it when I'm on a work trip and don't want to take my entire DSLR lineup) and it has a tiny sensor so it's been impossible to take photos in the dark churches. I wonder if I could have tried something like this? On the other Hand the sensor is so tiny the grain is very pronounced. Thank you for the explanation!

@jyokota With a tripod and 'median stacking' you can achieve a huge decrease in grain noise for any size sensor.┬┤If your photo editor does layers, Google: median stacking noise reduction.
