SO I've decided to go for an unsplit set up, and if I do not like it (Meaning if positioning the projector is to much trouble without keystoning) I turn to a split set up. The question is this: sice both fresnels are very close to each other should I calculate the focal distances for my light source and the triplet from the same spot? I ssume that if I go from unsplit to split I will have to ajust the distance between the bulb and the fresnel.


Thanks!
