Question about processing files

DxO PureRAW Feature requests
1

I am new to PureRAW. I use a Mac. I know that Pure RAW is for Raw files. While watching some YouTube Videos they said that PureRAW will not work on files which have already been converted.

MY INTERESTS:

  1. HDR
  2. Stacking Milky Way Photos
  3. Panoramas
  4. HDR Panoramas

When I try to create a final image from one of the 4 interests listed above should I run the PureRAW program first? If I am stacking Milky Way images… I will take about 20 images and then try to run them thru Starry Landscape Stacker to get a final image. I will probably make a tif or dng file. Although this program removes some noise…will PureRAW best be used before I process these images or after?

Same for the HDR. I usually shoot 5 images at + or - 1 for each frame. Do I run PureRAW before or after I turn the final image to an HDR image
Thanks,
DAle

PureRAW will not work with linear DNG files - only on undemosaicked raw files ( original from camera or converted - w/o demosaick - DNG files ) … PS: as far as I remember converted undemosaicked DNGs also shall not be lossy compressed

so you run DxO software first
