I came across this today – HDRsoft are temporarily giving away lifetime licences of Photomatix Essentials. Heres what they say on their website:
“We would like to play our small part in supporting the photography community in these challenging times.
We’ve gathered here a few resources to learn about HDR photography, and get you started with taking HDR photos.
We are also temporarily giving away lifetime licenses of our Photomatix Essentials software so that you can start creating your own HDR images.
HDR photography opens up a whole new world of photography possibilities, whether you’re an amateur, enthusiast or professional.”
