No, I don't. Yes, this forum shorten's URLs and this can break a link. The thread makes reference to the now illegal chemicals used in the process. -

The Panascope/UltraPan8 conversions of Marco Kroger
Nicholas Kovats replied to Nicholas Kovats's topic in Super-8
Your welcome. Jean Louis Seguin only converts Bolex H8 or H16 bodies. Marco is able to convert the smaller Russian Quarz models in a Double Super 8 UltraPan/Panascope model. No has converted the smaller and older Bolex Regular 8 models. Very tiny spaces to work with. No room for reflex viewing as Marco's work as attested to. -
The Panascope/UltraPan8 conversions of Marco Kroger
Nicholas Kovats replied to Nicholas Kovats's topic in Super-8
That's correct, Gabe. The image circle of R8/S8 lenses will not cover the UltraPan8/Panascope gate. But any standard 16mm C-Mount optic will provide sufficient coverage and then some as the UP8/Panascope gate is optically centered. -
Adapter on top of Adapter?
Nicholas Kovats replied to Tuan Doan's topic in Lenses & Lens Accessories
Les Bosher's excellent Bolex Bayonet adapters occasionally show up on eBay. They are the best if you are so inclined. His stock BBM adapters are Canon FD, Nikon F, Arri PLM, B,S. As someone mentioned previously keep it simple for best results regarding older SLR/Cine primes. He can almost build anything if the camera-lens registers allow for it. Worth every penny. Bomb proof. His Bolex Bayonet to Arri PL is very beefy with a built in support system. http://www.lesbosher.co.uk/ -

Sculpting light is for weenies I guess. It's a race to the lighting bottom as the DI people strike matches to illuminate their beloved square pixels. -

Sure. It will work. But the focal length of the CCD taking lens is critical for the very short distance involved. Some use tiny C Mount spacers to nail the distance from camera focus screen to CCD sensor. Trial and error.

There is a plethora of second hand 16mm C-Mounts on the market. Shouldn't be a problem to find one that suits your price range. Even cheap CCTV lenses.

No. The B 2008 is a Super 8 camera with associated lenses that cover the Super 8 frame not the larger R16 16mm frame. Unless you like vignetting.

Limits of Ultra 16 widescreen
Nicholas Kovats replied to Patrick Anton Saefkow Seaman_64263's topic in 16mm
Indeed. We of the obsessive aspect ratio. :) I might add that my personal UP8 R8 2.8 Bolex does happen to have a 2.8:1 viewfinder with 2.4 Cinemascope markings. It's a nice practical safety margin if one is so inclined. I might add that the historical antecedent is Ultra Panavision 2.78:1 as exemplified by the original Ben Hur and latest Hateful Eight. In fact Panavison has a working 2.78 projector setup that features the famous Ben Hur chariot race which apparently and ultimately convinced Tarantino to shoot in the UP format. -
Gorgeous footage! How much grading if any? Love the opening contrast with squarish low rez video. Film, film and more film please.

Thanks for the 10m DS8 link, Heikki. They have coveted 100ft DS8 rolls for my Bolex UP8 3.1 camera! And quite reasonably priced.

Limits of Ultra 16 widescreen
Nicholas Kovats replied to Patrick Anton Saefkow Seaman_64263's topic in 16mm
Patrick, I am not sure why the reference to "idiot" but it's a valid question. Entrenched and passionate opinions are par for the course in this forum when it comes to film transport discussions but human egos are just part of the equation. In fact your concept has been implemented to a degree in my two ultrawide film formats called UltraPan8 R8 2.8 and UltraPan8 DS8 3.1 , i.e. https://www.facebook.com/UltraPan8WidescreenFilm/info/ "FILM TRANSPORT: There are two specific variants. The first utilizes the entire 16mm width of 2 perf Regular 8mm film (R8) in conjunction with the 8mm pulldown cycle. It is called UltraPan8 2.8 R8 and debuted in 2011. The 2.8 designation refers to it's aspect ratio with an actual frame size of 10.54mm x 3.75mm. Note that this design uses the fact that Regular 8 film fundamentally shares the identical perforation dimensions of Standard 16mm film. Run time is effectively doubled relative to 16mm film magazines as there are 80x UltraPan8 frames per 16mm foot as opposed to 40. The imaging area is 113% greater than the Regular 8 format (SMPTE camera aperture). Check out a scanned example, e.g. The second adaptation utilizes the full 16mm width of 2 perf Double Super 8 film (DS8) in conjunction with a Super 8 pulldown cycle. It is known as UltraPan8 3.1 DS8 and debuted in 2012. The 3.1 designation refers to it's aspect ratio with an actual frame size of 13.00mm x 4.22mm. Note that the actual frame width is greater than Super 16. Also note that the Super 8 perforation is smaller dimensionally than Regular 8 /16mm which allows more of the 16mm film width to be used. Magazine run time is also doubled as there are 80x UltraPan8 frames per 16mm foot as opposed to 40. The imaging area is 34% greater than the smaller Super 8 format (SMPTE camera aperture), e.g. " The 2nd variant, UP8 DS8 3.1 does require recentering of the lens mount but I managed decent 3.1:1 frame coverage with my Zeiss Jena 10mm Tevidon APO C-Mount as per the 2nd scanned example above absent a re-centered lens mount. I don't have a scanned frame handy at work to illustrate the overscan parameters but the image extends beyond the left/right perfs. If your interested I can possibly post some frames in this thread. Oh yeah. The math. The total square mm areas generated by both formats is as follows, i.e. 1. UltraPan8 2.8 R8 = 10.54mm x 3.75mm = 39.53 mm2 2. UltraPan8 3.1 DS8 = 13.00mm x 4.22mm = 54.86 mm2 Cheers! Nicholas -
Super 16 converted to use double super 8?
Nicholas Kovats replied to Brent Powers's topic in General Discussion
Brent, Both UP8 formats are scanned by John Glehill at bitworks.org on a custom sprocketless scanner. Which is the key. A sprocket based scanner would require custom Regular 8 or Super 8 teethed sprockets that are 16mm wide. They do not exist. But there are a fair number of sprocketless 16mm scanners out there. The same logic applies to processing. My local film lab has a sprocketless 16mm processor and I label my exposed film clearly requesting no slitting. John's setup is a special custom rig and he is able to re-center his scanner lens to the UP8 optical center. Remember. Both UP8 formats are half the height of a 16mm frame. The sprocketless Lasergraphic scanners could also scan a full 16mm frame of UP8 footage resulting in two stacked UP8 frames per scanned frame. I am not aware if Lasergraphic scanner lens can recenter . It's all or nothing and is specific to R8, S8, R16, S16 and 35 Academy apertures. I do have an instructional PDF buried somewhere by a US based fan regarding extracting these stacked UP8 frames and then stitching them singularly into an image sequence for digital editing. In fact Lasergraphics almost developed special firmware for UP8 scans but nixed the project. Long story. But in essence it's a small market. But then again the CEO of Lasergraphics was not aware of the availability of 65mm film stock. I am not kidding. My UP8 scans are technically overscanned at approximately 3.5K resolution into a JPEG image sequence. Huge files. Very easy to import this into my Sony Vegas Pro. There are not full edge to edge scans like Lasergraphic based scans but the UP8 R8/16mm perfs are partially visible as are preceding and following frames. You can crop to your hearts content down to CinemaScope or 16:9 if you wish. Mind you the pixel density decreases accordingly. Cheers! Nicholas -
Super 16 converted to use double super 8?
Nicholas Kovats replied to Brent Powers's topic in General Discussion
Brent, This was implemented back in 2012 as per my UltraPan8 Facebook page, i.e. https://www.facebook.com/UltraPan8WidescreenFilm/info/?tab=page_info&view "The second adaptation utilizes the full 16mm width of 2 perf Double Super 8 film (DS8) in conjunction with a Super 8 pulldown cycle.

It is wider laterally than 16mm at 13mm. But I achieved good results as per the link above with a Zeiss Jena 10mm APO telecentric lens w/ a Bolex Bayonet to C-Mount adapter. The Bolex cameras are re-manufactured by Jean-Louis Seguin in Montreal, i.e. bolextech@gmail.com. -
Joe, I shoot regularly the optical center of my Angeneiux Retrofocus 5.9mm on my Bolex UltraPan8 camera. I had a Cameflex to Bolex Bayonet lens adapter machined by Jean-Louis Seguin so I could use it on my UP8 camera. Very wide in combination with the ultrawide UP8 format. That is about as wide as one can go with no distortion. Note the absence of any curvilinear distortion. The camera is hybrid of H8/H16 parts, i.e The next best option for your more rectangular H16 frame could be a KERN 10mm SWITAR with an Bolex ASPHERON 5.5mm wide angle. Not cheap. What is your lens mount? C or Bayonet? By Da Bay Store: http://tiny.cc/sd39by http://tiny.cc/ge39by A few lucky individuals have the Century 1.9mm, 2.5mm and 3.5mm optics for their Bolex. Very rare and super expensive. I guess I like good quality ultra wide angle optics. I am sure others will contribute some variations on the theme. Brent Finlay makes an awesome Super 16mm 5.3mm wide angle for C-Mounts, i.e. http://www.brentfinley.com/super16fish.htm

Has anyone modified the frame rate of a super 8 camera?
Nicholas Kovats replied to Rachael Tyrell's topic in Super-8
The best candidate are Bolex H8, R16 and the rare DS8 models. Tons of aftermarket animation motors down to sub-framerates. Was used as a standard animation/timelapse camera by the BBC for many years. -

Beautiful S8 K40 aesthetic, Serge. Well done. The music perfectly compliments the essence of Eastern European melancholy. Love the muted tones of the K40. Do you remember the camera you used?
