  1. Are there any previsualization software for lighting design (where you assign the lighting equipment, their densities, color and effect gels, exposure parameters, and their results on the subjects and cast in a 3D environment) specially made for cinematographers? I mean the FreameForge-like tool for DoPs and Gaffers... :rolleyes:
  2. As far as I know, Konvas uses retarded pull-down cycle same as Arri IIIC (maybe in IIC, I'm not sure). The claw waits engaged with the perforation until its movement for the next frame advance. I call it artifical register-pin :). And I remember that once OSTCAM of Moscow had made a register-pin for Konvas 2M... The clips of Thomas are very informative, but I prefer to look at the tests especially for registration shot on tripod totally locked, and best of best shot the Vernier pattern.
  3. I know that KONVAS cameras have single-blade 150deg mirror shutter. Recently, I have seen a two-bladed butterfly mirror shutter for KONVAS on internet. Is it possible to use it by changing the shutter gear? The butterfly types must rotate slower than the single blades. So it could be an advantage... Any comments?
  4. How does KONVAS stop the shutter in closed position when its off? By electronically via sensor feedback (like in CP-16R cameras) or mechanically (like in Bolex cameras)?
  5. "1KCP-1M.07.000" orientable viewfinder is used for both of 1M and 2M cameras. Is there also any special viewfinder for 2M camera or? What are the exact working angles of these viewfinders?
  6. Finally, I add the pix requested... Ostcam 16, Ostcam 35 and StarCam 35 respectively:
  7. Dear Kevin, I could not embed the pictures, I don't know why, and the Cinematography forum site is very limited to me... If you and anyone want to get the pictures, I can send them via email. Please send your email address via personal message. Best, Erkan
  8. Ostcams are history now... Here are few pix.
  9. What is Phase Shifting when filming video and computer monitors? How does it assure in cameras with shutter and pulldown mechanism are mechanically coupled? If its by means of specific speed, it will affect the exposure time and the motion in the video picture...? How does it assure in cameras with shutter and pulldown mechanism are electronically coupled or independent (like in ARRI 435)? If its by means of shutter timing, it will affect the exposure time...?
