Stacking Made Easy

 

If there’s one “secret of the pros” in landscape and real-estate photography, it’s stacking. Taking multiple photos and merging them together to capture detail that is lost in a single exposure. Arsenal makes stacking easy. It can take the optimal number of photos at the right settings, then merge the photos to a new RAW or JPG file. The new file is written back to the SD card and can be previewed on your phone.

 

I'll find out next year  by the latest.
