What does an increase in image height do to the furthest viewer distance for BDM viewing?

An increase in image height directly influences the furthest viewer distance for Best Distance for Maximum Detail (BDM) viewing. As the image height increases, viewers can experience a larger visual field, allowing them to perceive details more effectively from farther away.

In BDM viewing, the viewer's distance from the screen is typically related to the size of the image being displayed. A larger image enables viewers to sit farther away without losing the clarity and effectiveness of the viewing experience. This principle is grounded in the way our eyes perceive detail—larger images can maintain detail visibility at greater distances compared to smaller images.

The other options suggest that the distance either decreases, has no effect, or is halved, which does not align with the relationship between image height and viewer distance in this context.
