New kid starting out..
Have read till my eyes have swollen...
Purchased one of those kits for $10.00 bucks on E-bay and got hooked..Already purchased Optima flat panel and Metal Halide on the way..Had an old Kodak 3" flat field Ektanar lens laying around, so I started tinkering with my initial setup.
Which brings me to my question: The first fresnal I have is located approx 8 inches from light source which flattens the light nicely through my panel. The second fresnal is located almost 30 inces away from light source thus projecting an image small enough for the projection lens..Yet all the designs and how-to's show the fresnals close to 1 inch from the panel..What am I doing wrong ?
Any input is really appreciated..Thanks, Russ
