I dont believe there is a thread on here for HDR.

It stands for High Dynamic Range and it is a type of photo that must be taken on a tripod. It is made up of multiple exposures of the same picture, then tonemapped in programs such as Photomatix.

Here are a few of mine...

You don't have to use a tripod, I think compensation for camera movement is a fairly standard feature today. Photomatix allows you to manually or automatically align, and it can also compensate for movement in the scene to some degree.
 
Here is a handheld 3 bracketed image.

I take back what I said about "needing" a tripod. You can hand hold a few shots, but for sharpness and for 7+ photos you need one. I tried with my d200 to handhold a 7 bracketed image and some of the images did align in photomatix, but it wasnt sharp at all and if you want to shoot anything with good contrast early in the morning or later in the day, then some of your images are going to have a longer shutter.

Technically you can do something similar to HDR with video.

HDR is taking images taken at different exposures and combining them to create an image with an extended dynamic range.

An easy approach to HDR, if you don't have original seperate images, is to simply take your JPG and save that image with different exposures, for example, one at 1 stop higher and one at one step lower. This yields identical images at differenet stops. This is easy to do with Photoshop. That being said, how much additional dynamic range you are revealing, especially with a JPG is debatable and maybe not even noticable. You would then simply combine the images and take the final image and reimport into the time line.

For as comfortable as I am with actions, this would be a tedious process to say the least as I've never tried to actions with HDR...

The real impact of HDR though, and why this method could work, is because HDR doesn't have that breathtaking look because of the actual bracketted shots, but also because of the tone mapping people apply. HDR shots are nice, but being able to tone map them truly yields that awe inspiring feel. The above method would work for video in so far as allowing you to tone map and get that hyper realistic / animated look.

How practical is this method? I wouldn't do it, but it COULD be done for video... most likely less painful than rotoscoping, but then again, I couldn't do that either :)
 
Nice theory Jeremy, could you post a 5 second clip to back that up? I would love to see an HDR video, even if it were a few seconds.

24 frames per second... 5 seconds... 120 frames....


No, not going to do it unless I have a point to do it.

I will take a simple JPG and show how it can be tone mapped thogh.
