.HDR
Hey guys, this is moreso a film question than an after effects question, but I figured I’d post it here. Are there any video cameras available that fire out .raw file format sequences? I’m firstly a photographer, and I’ve familiarized myself with .hdr formats, and making it look nicey nice with even exposure throughout a frame. I’m trying to bring this to video — I’ve done it with a D70 by rapid firing .nef files — at about 8 fps or so b/c of the buffer — and of course frying the battery pretty quick.
If anyone has any ideas — or has done this without scanning individual peices of film at 5 exposures per film —

Nicolas: there are no cameras that record in the same raw format still cameras use (in fact, even Canon and Nikon use different formats for that), but there are some VERY high end and expensive cameras that record a raw HD stream to hard disk. You would have to sell your entire familiy to afford using one of those, though 🙂
Besides, as I understand it, HDR sources are not so much (or not just) about the RAW format as they are about combining different exposures to produce an image with super wide latitude, right?
The Automate to HDR feature in Photoshop is only available for still images. The same process for video footage could be developed, but as far as I know it’s not available today. With some automation skills, though, you could convert video footage to a numbered still image sequence, produce the HDR exposure fusion, and finally convert the resulting frames into video again. It shouldn’t be that hard. It could be more about clever automation than manual work. Could be a nice experiment!

Damn it. Gotta sell the family again.
Yeah I figured you could just import at different settings and adjust the tone — but it isn’t going to record the actual luminance key — thats the issue. Unless we could have a single lense with 3 hard drives recording the same footage at different exposure levels, and then set up the batch. I already have my pipeline figured out — I just need to get the .hdr sequences!
thanks again

Nicholas: there’s a cheaper alternative to selling the family.
It’s called 3D 🙂
Most professional 3D applications today will let you create HDR environments where latitude is not limited by film or sensor latitude. They will even let you use your HDR still images as textures. How about that?

yeah I use cinema…
but the proper exposure of skies and interiors of the real thing just look so damn cool.. -
Is is possible to use RAW video from a simple T2i and somehow manipulate the gamma and color settings of different layers using partial opacity or masking to approximate HDR or at least footage with wide dynamic range? (i.e., bright windows on an interior).
