Sometimes you might want to change distance or screen size units - when you have screen size measured in inches or your customer from abroad provided metric measurements.
Image size toolbox is related to aspect ratio and lets you define your screen size using width, height or diagonal measurement.At Open Air Cinema we are used to defining screen size in width. When we say 16 ft Home Screen it means that it has 16’ wide and 9’ high projection surface.
Throw Distance toolbox is related to a screen size and means distance from the projector to your screen. More distance means larger image, but less bright. In real-life situations, throw distance is also limited by a lens focus range.
Both throw distance and image size values can be locked. This is useful for example when you nailed down your screen size and want to estimate possible projection distances.
