Request for Pentax HDR raw files

I just added support for Pentax HDR raw files (3 raw frames in 1 file) to HDRMerge.
Currently I only tested with files from K-1.
Dear pentax users, please share some HDR raw files from other cameras :slight_smile:


You know about

Sure, but I didn’t find Pentax HDR raw files there.

Status report:

I already got some raw files.

Currently I can confirm it works fine using:

K-1 PEF and DNG
K-3 PEF and DNG

Files from other Pentax cameras are still needed.

Please make builds of latest master branch to get more tests!

Just a reminder: for the Linux case, you can test the latest git version using the nightly AppImage packages from here.


Pentax K-3 II HDR files can be found here:
Seriously boring out the window shots of dubious exposure but should at least work as tests to see if K-3 and K-3 II work the same. Just test one of the two.

Sorry, I forgot that. Going to rebuild.

The uninstall section seems not updated accordingly.

Here is an HDR.pef from a Pentax KP.

Will the non-HDR formats also be compatible?
