How can I create an OpenEXR HDR file from bracketed JPEGs with pfstools on Linux or macOS?

I want to combine multiple bracketed JPEG exposures into a single HDR file and save it as an OpenEXR (.exr) from the command line using pfstools. I’m already familiar with tools like enfuse, but I specifically want an EXR output workflow with pfstools on Linux or macOS.

Just guessing (I've never used pfstools, but I once maintained a man page set as a technical writer), you could probably use pipes and commands like the following example:

pfsinme*.jpg |pfshdrcalibrate -r linear -v |pfsoutresult.exr

This reads all the .jpg files in the current directory, merges them into an HDR image (with linear response) and saves the output as an Open EXR image.

With pfstools, the basic idea is to pipe the input images into an HDR merge step, then pipe the result to an OpenEXR writer. A typical command is:

pfsinme *.jpg | pfshdrcalibrate -r linear -v | pfsout result.exr

What this does:

pfsinme *.jpg reads the bracketed JPEG exposures
pfshdrcalibrate -r linear -v merges/calibrates them into an HDR image
pfsout result.exr writes the HDR result as an .exr file

This is a standard Unix-style pipeline, so it should work similarly on Linux and macOS if pfstools is installed and the EXR output support is available in your build.

If the exact command names or options differ on your system, check the man pages for pfsinme, pfshdrcalibrate, and pfsout to confirm syntax and supported formats.
