Hello, I am a newbie here, and am planning on doing my own DIY ohp (overhead projector) mod soon...more details on that to come.
Anyways, I have been reading non-stop in these forums and others for about 2 weeks now, and I have a question:
First off, on an overhead projector, I see that the singlet or tripplet lens sometimes comes before the mirror, and sometimes after, if you knw what I mean.
Which one would theoreticly produce a better immage/contrast/quality picture? will it make that big of a difference?
Thoughts?
