Poor projection technique - washout

Washout of projected images.

In this scenario the staging crew or the organiser, depending who was in charge of the lighting control, forgot a critical rule.

We can not project 'black color'. In fact, when we project Black (or very dark colours), there is nothing on the projection screen. Now screens are designed to reflect or transmit light. However, if there is nothing on the screen, any other light becomes visible. In this case the Fluorescent lights, which are creating a non defined illumination.
The result. A washed out image, low contrast and low brilliance.
Very unfortunate in this case, since the aim of this presentation was to promote a new camera and the image quality.

So it is important to switch of any non-essential light if we want to have outstanding projection. Fighting light with light, simply does not work.

By the way, if you use LCD monitors with a glossy glass the same issue applies. If there is not bright content on the screen, other light will reflect in the black area and disturbs the viewing experience.
