Gordon C Posted August 13, 2011 Share Posted August 13, 2011 I saw there is an alternative to building an anamorphic lenses for projection purposes and I suspect I could use it to film it right in front of my DSLR. But the problem is I want to know if there is any formulas to ensure us that I am getting the image squeeze that I prefer. Link to comment Share on other sites More sharing options...

Gordon C Posted August 13, 2011 Author Share Posted August 13, 2011 Thanks Dan, in fact I found it from that site at first but right now I have two wedges but don't know how to assemble them because I need to find a viable math formula to correctly place each prism in the right place to get the ratio magnification I want. I want to make my prism squeeze from 16:9 to 2.40:1. Link to comment Share on other sites More sharing options...
dan kessler Posted August 14, 2011 Share Posted August 14, 2011 Well, your first calculation will be 2.4/1.78 = 1.348 This is your anamorphic squeeze ratio. After that, things get a little trickier. When I google 'anamorphic prisms,' all sorts of diagrams appear, but no simple formulae. Looks like you'll have to do some digging. Link to comment Share on other sites More sharing options...
