IOD Calculator
A calculator for 3D photography. The stereographers best friend! It calculates the inter-ocular distance needed for each camera setup based on measurements from the actual set. Provides handy sliders and nudge buttons to set the distances to the nearest and farthest objects in the scene, as well as the desired convergence point – whether or not you converge in camera or post. The sliders are logarithmic so you get finer control at the short end.
Calculates the foreground and background divergences as percentages and actual distances for your chosen screen size and limits the background divergence to infinity. – Also computes roundness factor so you can match the apparent depth from shot to shot even when changing lenses and setup. – Operates in metric and imperial. – Suitable for Motion Picture and Stills work, Film or Electronic cameras. -Best of all it’s fast and intuitive. Settings for: – Camera sensor size, with a whole bunch of presets for both film & electronic cameras. – Lens kits – enter the focal lengths in your kit for fast selection. – Screen Size – with handy presets for TV, cinema etc. – Maximum permitted overall divergence – typical is 3%. – Maximum background divergence in actual mm on your chosen screen size – typically 65mm.
