Lobby. Figure 6 shows a lobby outside the experimental testing room. Images were recorded on a sunny morning in late July. Before direct sunlight reaches the lobby (A), the dominating contrast features on the floor are along the carpet and around the stairwell, thereby indicating the presence of each. However, as the rising sun passes through the lobby (B–D), the dominating contrasts are along the boarders of the shafts of sunlight, which can mask informative features of the space, such as the carpet on the left and the hazardous stairwell on the right. High dynamic range and false color images were created using Anyhere Software.
