Flickery light room series#

When I post process an image, it means that it keeps blinking as I move between sliders. This means that every time I make an adjustment the image goes dark, and then back to normal, showing (in real time) the result of my adjustment. Meaning, every time I click an adjustment slider, the image gets really dark, for a tenth of a second, and the revert back to proper preview of the adjustment. My problem is really that Lightroom keeps blinking.

Experience rapid eye movements behind closed eyelids.

The strobe light effect can cause persons who are vulnerable to flicker vertigo to experience symptoms such as: Flicker vertigo in a helicopter occurs when the pilot or front passenger looks up through the blades of the main rotor as it turns in the sun causing the light to strobe.

Bucha identified the phenomenon in the 1950s when called upon to investigate a series of similar and unexplained helicopter crashes. This phenomenon has been observed during helicopter flight a Dr. The effects are similar to seizures caused by epilepsy (in particular photosensitive epilepsy), but are not restricted to people with histories of epilepsy. Flicker vertigo, sometimes called the Bucha effect, is 'an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light.' It is a disorientation-, vertigo-, and nausea-inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of human brainwaves.
