Cmdline - Skip DNG conversion if images are already DNG

Post by IhanaMies »

Is it possible to run Helicon Focus from cmdline skipping the DNG conversion if files to be processed are already in DNG format?

I created a small program to run different stacking algorithms with various options to examine the output differences and I found out the DNG conversion happens in every run. So I thought running DNG conversion myself to a temp folder and point Helicon Focus to run against that folder as many times as I needed, but noticed the conversion still happens, not saving any time I thought.

Thanks

Hello,

You can open Helicon Focus in the usual graphical mode, load a DNG file, click "Raw development settings", select the "DNG loader" codec and click "OK" to save. But keep in mind that not all DNG files can be loaded in this way, only linear (debayered) files can.
The choice made via the graphical interface will apply to the command line mode as well.
