| I've experimented with HDR photography a bit and you can't do a perfect HDR merge in After Effects using only plugins or transfer modes. But if your source footage has a very wide latitude, then you can use simple layer stacks to recover shadows and highlights. In 32bit mode, stack your 3 layers on top of each other with the add transfer mode, and then use an adjustment layer on top of them all to control exposure and recover highlights. I've played around with combinations of 'exposure', ' HDR highlight compression', 'HDR compander' and 'levels'. Depending on your footage you might get a better result than a straight 8-bit pass, but render times are very slow. -Chris On 01/01/2012, at 6:13 AM, Dave Bittner wrote: > I've got some footage from a Photron high speed camera that's presented an interesting challenge to me. The camera records a sequence of images that have a 48 bit depth, which is a large dynamic range. On export to QuickTime, however, you are forced choose a bracketed range of 8 bits. After multiple exports, I'm left with a movie that's underexposed, one that's properly exposed, and one that's overexposed. I want to combine then, HDR-style, to show the details in the highlights. (The footage is a series of explosions, so there's a lot going in the highlights.) > > Any tips for stacking the footage in AE? > > Thanks! > > Dave Bittner - Pixel Workshop Inc. > www.pixelworkshop.com > 410.381.8555 > Twitter @bittner > > > > > +---End of message---+ > To unsubscribe send any message to <ae-list-off@media-motion.tv> > |
