??? HDR processing using VIDEO files ???
« on: August 08, 2007, 01:51:04 PM »

Hi

I have been looking to HDR process videos similar to photogrpahers processing
images.

Is it possible? what kind of software? etc.

I heard there is a company making the hardware and software for real time HDR  video processing but I lost track of it.

Regards

It's not possible. HDR requires blending two exposures with different shutter speeds, and it really needs RAW images to work well. Only a very few very expensive video cameras allow RAW capture, and they cost more than most houses. And they don't take simultaneous exposures with different shutter speeds.

I guess we are not there yet......   I am not sure why, because the technology is there.
