Premium Member Jason Debus Posted December 28, 2006 Premium Member Share Posted December 28, 2006 The bokeh in The Oh in Ohio seems anamorphic, but supposedly it was shot with spherical lenses (according to imdb). I've seen this in other films before, what type of lens causes this type of distortion? The bokeh seems a more rectangular oval than anamorphic. This screen grab from the trailer isn't that hi-res but it's all I could find after watching the DVD: Link to comment Share on other sites More sharing options...
Mitch Gross Posted December 28, 2006 Share Posted December 28, 2006 Looks like a matte in the mattebox to me. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted December 29, 2006 Premium Member Share Posted December 29, 2006 Looks kind of like an anamorphic lens artifact -- beats me... Link to comment Share on other sites More sharing options...

Premium Member Andy Sparaco SOC Posted December 29, 2006 Premium Member Share Posted December 29, 2006 Looks like a composite shot to me. With the background stretched or blown up a bit in post Link to comment Share on other sites More sharing options...
Premium Member Jason Debus Posted December 29, 2006 Author Premium Member Share Posted December 29, 2006 The screen grab from the trailer I posted is a terrible example because it's kind of a wide shot. I think Mitch is on the right track, a matte box or something obscurring the circles. I would like to understand what is actually going on a little more, is it like vignetting? Here's a diagram of the type of bokeh I'm talking about: Link to comment Share on other sites More sharing options...

Wouldn't optical vignetting be more noticeable near the edges of the frame and gradually disappear toward the center? Link to comment Share on other sites More sharing options...
Nick Mulder Posted December 30, 2006 Share Posted December 30, 2006 Maybe there were just a few scenes with what were registered as point sources of light in the background that were in fact oval or rectangular sources that naturally produce the elongated bokeh that has caught your eye ? It certainly is possible with the example frame grab we have here. That being said I haven't seen the whole film so cant comment on the rest of what you have described... yeh yeh ? no ? :rolleyes: Link to comment Share on other sites More sharing options...
