I am NOT selling anything here. I make my money the old fashion way. I work at a job. However, I want to save people time. What I learn I think has some value and I want others to share in it.

Here's what I spent and my learning process...

I bought $50+ in many different Fresnel lens (the 3D Lens high quality large Fresnel lens is cruddy!). What I found out is that the $3 fresnel lens (page magnifier) works just fine! The trick is how to correct for the blooming of high contrast images which happens using any Fresnel lens. I looked around and no one has the second aperture like I am using for off axis correction (removal). BTW... My screen is approximately 120" =8' x 6'.

This works and I want no money. Just tell me what you thought and tell others. I have an attachment that I would like someone to try that already has been down the projection TV path and was dissapointed. Give me some feedback or email me if you have any questions.
