Our first section, from our front page, is "Rules, feedback
and new member intros" so for the sake of consistency I'll move this post there and leave a shadow behind so you can find it.
We don't, as you know, have a dedicated HDR section but the current repository is Imaging and Video Editing Software
where, for example, you'll find the thread HDR Tutorial - Beginners Guide
. That said it still makes sense for posts showing off HDR work, as opposed to describing how to produce it, to go in the relevant Photography showcase, discussion and Assignment
section. Hope that helps.
