Hey thats a pretty sweet app!

I do have one question tho, and please tell me if I'm wrong, but in order for an image to qualify as a true HDR image, doesn't it need to be floating point throughout its lifecycle?

Starting from a standard .jpeg defeats the HDR purpose does it not?
I mean, a standard .jpeg does not natively carry enough information for the super-brights and super-blacks that a floating point image does correct?

Again, please tell me if I'm wrong

Cool app tho!
