I've noticed this feature being asked about in other threads and wanted to share my desire for batch merging to HDR in Affinity Photo.
As someone who does a lot of HDRI work I've gone through my fair share of different software searching for the best results (Photomatix, HDR Expose, Dynamic Photo HDR along with pano stacking with Autopano Giga and PTGui etc). After purchasing Affinity Photo I've found that in most if not all cases it's HDR merging has the best automatic ghost removal and processing of any app I've used, yet it's the only one without some sort of batch tools for multiple stacks. Currently I am manually sorting through 500+ separate stacks for a project I'm working on and would greatly appreciate (as well as pay for) a means of running these through a script to automate it all.
