|
|
i read Kal's article and i taped my eye one to a tripod. i started at about 4" from the screen, but found that my highest y reading was about 2 feet back! i was slow and methodical, but this seemed strange. Perhaps the reason is the screen i'm using? Da-Lite - High Power Projection Screen
would the distance matter, as long as its the brightest measurement?
This screen surface is a technological breakthrough, providing the reflectivity and optical properties of traditional glass beaded surface with the ability to clean the surface when required. Its smooth textured surface provides the highest gain of all types of screen surfaces with no resolution loss. The moderate viewing angle and its ability to reflect light back along the projection axis make this surface the best choice for situations where there is a moderate amount of ambient light and the projector is placed on a table-top or in the same horizontal viewing plane as the audience. Can be washed with soap and water. Flame retardant and mildew resistant. Gain: 2.8, Viewing Angle: 30°

I used to think closer is better, because there is very little talk about this oddly. I now have it farther back like you.
