The bright scene is ringed by a darkness that swarms with faces and figures, like bad memories that refuse to be quieted.
Mr. Laspina, now 57, took a step back from the window and captured a much brighter scene in its dusty reflection: dozens of young men scattered in and around a tattered boxing ring, sparring, jabbing at speed bags and jumping rope.
"I was looking at the G.E. one, and my first reaction was, everyone in there is smiling and happy, and it's a very bright scene," said Timothy B. Heath, a marketing professor at Miami University's business school.
You don't want the whites to be so intense that, when you look at a bright scene, it looks as if you're in a whiteout on a ski slope.
Otherwise, find a bright scene on a movie — a woman's white wedding dress, for example — and adjust the contrast control so the dress retains detail, like fabric folds or buttons, without becoming a mass of indistinguishable white.
The global mapping algorithm adapts to different image dominant tone, and it is capable of enlightening dark scene or dimming bright scene back to normal-key appearance of images.
If you've been using an iPhone for a while, you know that there's a setting that lets you automatically enable high-dynamic range (HDR) if you're looking at a bright scene with some dark elements.
Again throughout the rest of the brighter scene luminances, P6 and P7 performed correctly on unmatched control trials but not on scotopically-matched test trials (Fig. 2b, symbols).
The results P1, P3, P6 and P7 were consistent with no cone-based vision being used for the orientation task and retained rod-based vision functioning adequately for orientation even under bright scene luminance conditions [ 17].
The negative quadratic coefficient in the luminance-only GLMM suggested that fixation probability is maximal for image patches with medium-luminance, and is considerably reduced for both very dark and very bright scene regions.
