I didn't find it funny at all really.
I wasn't insulted, but its just all a bit pathetic really.
Its almost like back when photography was first considered an art, and all the artists with their paintbrushes and easels were all like, "Pfft, thats not art, its a monstrosity!", sipping their port and toffing away.
Its just pathetic.
Some people over-do it with their lack of understanding, while others use it to great effect.
So what if someone uses HDR.
Get a grip.
