Brian Drysdale Posted April 14, 2012 Share Posted April 14, 2012 Just looked at the latest Aston sheet for the digital Penelope, no doubt just out for NAB. http://www.aaton.com/files/delta-p_april-2012b.pdf The interesting bit is how they're achieving the camera's lower ISO rating by using a multi slot shutter with a 100 ISO setting, so avoiding the use of ND filters. I was wondering how they were managing it. I expect there'll be a lot of testing for artifacts from this new arrangement. Link to comment Share on other sites More sharing options...

Tim Tyler Posted May 1, 2012 Share Posted May 1, 2012 Looks like an amazing camera. CCD eliminates rolling shutter issues. http://www.aaton.com/products/film/delta/ The first optical viewfinder digital camera with an internal SSD recorder (DeltaPack*) for full rez CineDNG ucompressed RAW (the Adobe archival format based on open standards), and editorial-ready proxies. * DeltaPack is compatible with the codex® backstage and post station workflow. Lightweight: 7.5 kilos with internal recorder and two onboard 14V Li-Ion batteries. Two to five hours‘ autonomy; power dovetailing during changes. Designed for earthlings, Delta respects Aaton‘s first commandment : Cat on the Shoulder profile, plus wide flat base for tripod. No eye-strain bright viewfinder with large peripheral coverage. . Rotating mirror shutter; no rolling shutter artifacts. Main selector eliminates complex menu navigation and gives direct access to operating functions from both the operator and assistant sides. Location sound-mixer friendly, Delta is noiseless in both record and pause ( Unlimited number of cascadable preset 3D LUTs for RAW metadata on one hand, and for on-set control screens on the other. 14 stop dynamic range Super35 Dalsa® CCD sensor, 800 and 100 ISO sensitivities (patent pending) eliminate the need for special anti-IR neutral density filters. 90% pixel-fill allows for wide angle lenses with short exit-pupil distance.

Premium Member Keith Walters Posted May 1, 2012 Premium Member Share Posted May 1, 2012 Do they state the sensor's native resolution anywhere? All I can find is: "Dalsa® sensor’s 90% pixel-fill allows for 7K pixel sampling" If you can afford the mirror shutter, Dalsa's simple 40-year-old CCD design still gives the best results, since almost the entire silicon area is used for photon capture, without the complication of microlenses.

Chris Millar Posted May 1, 2012 Share Posted May 1, 2012 Looks like a fine piece of engineering... er, so can anyone explain what a '100 ISO' shutter is ? (last time I looked up a patent I remember thinking never again) Whats going on with those slits ? Link to comment Share on other sites More sharing options...
Brian Drysdale Posted May 1, 2012 Author Share Posted May 1, 2012 Whats going on with those slits ? I assume it's a means of reducing the amount of light passing through, without reducing the effective shutter angle. I guess it acts as a series of travelling slit shutters, which combine to provide the complete exposure. Link to comment Share on other sites More sharing options...
Premium Member Vincent Sweeney Posted May 1, 2012 Premium Member Share Posted May 1, 2012 Does this mean that non-film movie cameras will finally be able to record red lights without them turning white and/or pink? Current digital nighttime street shots are already looking dated. Any word on shipping dates or price? Link to comment Share on other sites More sharing options...

Yup, I get it, and you've already touched on temporal aliasing issues which was my next thought. Link to comment Share on other sites More sharing options...

Premium Member Keith Walters Posted May 2, 2012 Premium Member Share Posted May 2, 2012 We also now need a new folder; clearly this doesn't fit in "Aaton Film". Why not just "Aaton" since there aren't that many Aaton-related posts? Or is that about to change...? :rolleyes: Link to comment Share on other sites More sharing options...

Chris Millar Posted September 29, 2012 Share Posted September 29, 2012 Moving the sensor half a pixel - very interesting! ;) '7k' though - not sure how to achieve it without having your screen and or projection also moving half a pixel every frame - huh?

Brian Drysdale Posted September 29, 2012 Author Share Posted September 29, 2012 Interesting to find out theory behind that, it could be a perceived "dynamic" resolution over a number of frames as against a stand alone single frame resolution. The Camera records RAW, so there could be a bit of post processing going on. Here are some test images: http://www.marquise-tech.com/resources.html#tabs-5 Link to comment Share on other sites More sharing options...
Chris Millar Posted September 30, 2012 Share Posted September 30, 2012 Thing is the end product has a single frame resolution... But one of 7k? Oversampling? To be used in? VFX/comp work? Link to comment Share on other sites More sharing options...
Brian Drysdale Posted October 12, 2012 Author Share Posted October 12, 2012 Whats going on with those slits ? I believe there are 20 slits and looking at some still frames in a CML thread the motion blur does look pretty normal on the number plate of a moving car.
