Marc_Roovers -- and others
The following (from suggestions by Marc Roovers) is extremely useful for focus stacking where 100 or more exposures might be made all with the same settings.
Make the exposures all focused slightly further away from the starting point.
I use a StackShot rail controlled by ZereneStacker but there are other ways.
Edit the first of many exposures manually with RawTherapee
Save a *.pp3 file, perhaps named as my_pp3.pp3
Create this script, perhaps named as rt.sh
Make it executable with "chmod +x rt.sh"
change directory to where your raw files are.
rt.sh ....press the enter key
rawtherapee -o $pwd/ -b8 -t -p my_pp3.pp3 -c $pwd/*.NEF
Now each Nikon *.NEF raw file is converted to *.tif using the edits defined in the first manual editing session.
Now use third party software to make the stack as one final *.tif. Edit the stacked *.tif with Gimp or Photoshop. Save as jpeg.
The script above will work on Linux and/or Mac.
How would a person do the same on Windows?
Windows 10 apparently has a bash shell that can be installed.
Are Windows7 users out of luck? Is cigwin the only alternative for Win7?
