  1. Looks great ! Is there some vignette on the right side ? I imagine how good it can be on S16. Would not be a bad idea next time to show some girl model instead :-)
  2. Good day Guy, i have a frame by frame scanner for 9,5mm too.It is 2560x2048 pixel uncompressed TIFF output in a folder image sequence. From this image sequence you can convert in whatever video format of your choice. I charge 1 Euro/meter.Are your 2000 feet( 609 meters) loaded in a single big reel ? My scanner can load 120 meters max, but i have not problem to customize for bigger reel. Roberto https://www.facebook.com/265618923958142/videos/268955433624491/
  3. Well, i do a sort of wet gate with diffuse light too. To me diffuse light helps with my sysyem since i have tested collimated light with worse achievement . I soak the film with vaseline oil then pass trough mechanical cleaning system. This way dust and dirt are removed and the film remains wet. Finally i scan the film emulsion for the highest quality. I can scan from sd to 2.5k to image sequence. This system works best with reversal, with negative film the difference is not noticeable aside dust and dirt removed. Here a brief description. (hem , the voice is robot,sorry for some weird pronunciation) https://www.facebook.com/265618923958142/videos/268955433624491/
  4. I have done conversion on all my Bolexes and never noticed steadyness issues after. The exposed area is the same more or less, the main difference is the wider aspect ratio vs S16 frame. The main issue are the codes on the side between perforations, so you can not scan all frame width.
  5. I have used Peleng 8mm lens on a Bolex reflex and it delivers very good images for its price , but you can use only f 5,6 iris. More open or closed iris will degrade quality very quickly
  6. well, there is electronic inside EBM ofcourse , but you must only connect + and - connectors ( 12 volts)
  7. Well , a good serviced cinecamera can deliver supersteady frames. My Bolex EMB has nothing to envy those pin registered cameras. An electronic video image, with its artificial/flat look can only forget the warm/pastel look of cine film. To me the "brutal " truth about success of video over film is only related to its immediate availability
  8. Well, i have done it and never got problems . After all the switch in the handle acts like a remote ( very short in this case) switch along the cable as you want to do. All the best. Roberto
  9. Well, i was meaning to practice with sun only, to test exposure. Remember that the less glasses you put in front of the lens the better. I upload a test i made just now with a 1/2.3 inch video camera and 200 mm tele lens (iris at f11) with 2 polarizers . The picture is slighty out of focus because these polarizers distort image quality, i can figure how much bad can be with multiple ND filters !
  10. May be i read your post too late and your solar eclipse is already gone. Well, whatever camera you will use , video or film, since it is a total backlight you will get always heavy contrast picture, only white disk (sun) and only black (moon) disk. Anyway, i would go in this way: use a double polarizer filter and rotate one of these till you can easily see the sun with your eye (BE VERY C-A-R-E-F-U-L !). Then use a telephoto lens that can fill the frame with sun disk. Adjust exposure either by slighty rotating one of the polarizers and or setting iris . You can test it with a videocamera before to shot film. Hope it helps
  11. Here the Super 8 SMPTE frame taken with 4K session 5. Well, to me quality is not so good, it suffers from the crazy ( exaggerated) H264 compression, not suitable for telecine/datacine purpose. The lens used comes from a microfilm scanner and it is an ultra-high resolving power lens
  12. If you want to use a gopro you have to remove original lens first, and fit a very high resolution macro lens. To open a hero 3-4 cameras is not so difficult, you can find many samples on the net. Other thing is to open a session camera, since it is all glued and sealed one. the only way to remove original lens on a session is to mill the contour in front of the lens first to enlarge the front panel and free the objective then remove with a needle the glue around the lens. Finally, with a specific tool that clamp around the outer objective diameter, unscrew gently the lens. I have just done it, and now i am building a C mount adapter that fits in this camera. As soon as i will upload some stills from S8 and 16 frames
  13. Hello Tyler thanks for reply, well, the only gears that risk damage ( to me) is the pulldown claw mechanism. The others gears could run indefinitely at faster speed than 100 fps, untill they are correctly lubricated. Anyway, i was curious to know if anyone has tried it before with an external motor for example.
  14. Hi all, the motor of my EBM is gone, so i was thinking to replace it with a faster new one to achieve higher speed than 50 fps of the original one. The question is : how higher speed can run a Bolex without damage mechanics ? For my purpose 100 fps is the goal. Thanks in advance
