I was lucky enough to see this wonderful piece of work in advance, and viewed it on a Samsung 100hz 1080p TV through a PS3. It is, without doubt, the best image I have ever seen on a TV screen of any sort. To date, I would say Blade Runner is the best transfer from a non-digital source, and that was shot on 35mm and scanned in at 4K resolution, which is a far "finer" definition than can be displayed on domestic television sets at present. Well, Baraka was shot on 70mm, and has been scanned in at 8K, and the result is absolutely knock-out.
When I first moved to HD, I was hoping that Baraka would get the treatment it so rightly deserves, but knowing the high costs involved, I thought it would never happen. Well, obviously someone out there has deemed it worthy of that cost, and I can only thank them for it.
If you haven't seen Baraka but are interested in seeing it, you really should pick up a copy. It's the perfect demonstration of HD, although that is secondary to the work done by Ron Fricke and his crew.
If you're already familiar with Baraka and wondering simply whether this is a Blu-ray worth picking up, please, take my word for it, it'll be a while before this is beaten. I just hope you have TV with the specs needed to really get the best out of it.
