Its time to introduce a HDRI workflow

[Robert Niessner]

Dude, last time I was in Graz (on my way to ski at Pitztal) I almost crashed. I got shivers just seeing Graz bellow Your name... :waaa:

Sorry to hear that. Hope the next time you visit you take better memories with you.

Peter, by chance, do you have something to do with the Diamant film restauration software developed by Joanneum Research? Because you mentioned earlier being in this business.

We have seen de-interlacing algorithms develop over time and do magic to temporal artifacts. Therefore, I am not so sure whether it is really _impossible_ to overcome the problem of freezing time.
There are very bright minds working on the problem of DR from different perspectives. Time will tell which approach turns out to be the most practical: dual sensors, multiple time-shifted exposures with some kind of intelligent algorithm to minimize temporal artifacts, new and better sensors, or improved processing of a single existing raw frame with tone-mapping or other techniques.

Living on the Tibetan plateau with its amazing sun and harsh contrasts I am confronted with the problem of DR every day. What I see (with a decent pair of sunglasses) is hardly ever what I am able to capture. I have been playing around with HDR in still photography and I know that moderate HDRI with maybe 13 stops of DR ("compressed" to what a monitor is able to show) often do the trick and look much more like what I see with my own eyes. These images do not look surreal, but suddenly there is life in the shadows.

I did study it in a great detail as part of my research for Kurosawa. I have also seen the actual use of the system at KODAK MUSEUM in Rochester. However we have decided to go a different way. Our system ended up being based on PMA (Pixel Motion Analysis) engine developed by Simon Robinson at The Foundry (http://www.thefoundry.co.uk) and SHAKE's open architecture - all based 100% on Apple HW and OS-X. We did some heavy modification which benefited both our project and Simon's products directly. BTW - Simon's team won the "technical" Oscar for this technology...
