Flashed glass, [1] or flash glass, is a type of glass [2] created by coating a colorless gather of glass with one [1] [3] [4] or more thin layers of colored glass. [5] This is done by placing a piece of melted glass of one color into another piece of melted glass of a different color and then blowing the glass.
Flash-gas may be detected in the system by the observation of gas, bubbles or a foamy appearance of the liquid in the viewing glass in the liquid line. Depending on the location of the glass, this may also indicate an overwhelmed condenser, and the lack of these indicators at the glass does not definitely rule out flash-gas formation in the ...
A flash diffuser (also called a speedlight diffuser, or shoot-through diffuser) spreads the light from the flash of a camera. A diffusion filter of this type may also be used in front of a non-flash studio light to soften the light on the scene being shot; such filters are used in still photography, in film lighting , and in stage lighting .
The effect is produced by adding a small and even level of exposure to the entire image. Since exposure levels increase logarithmically, this tiny level of additional exposure has no practical effect on an image's mid-tones or highlights, while it shifts the darker areas of the image into the practical sensitivity range, thus allowing the darker areas of the image to show visual detail rather ...
The flash fully discharges before the arc can move away from the glass and fill the tube, causing excessive wear to the lamp. Simmer-voltage triggering is the least common method. In this technique, the capacitor voltage is not initially applied to the electrodes, but instead, a high voltage spark streamer is maintained between the electrodes.
Dust particles reflected by a smartphone flash. In underwater scenes, particles such as sand or planktonic marine life near the lens, invisible to the diver, reflect light from the flash causing the orb artifact in the image. A strobe flash, which distances the flash from the lens, eliminates the artifacts. [7]
"The Bud Light story is really astonishing," Tim Calkins said. What started out as a Bud Light beer plug with transgender influencer Dylan Mulvaney back in April has become a tsunami of backlash ...
If the throttling valve or device is located at the entry into a pressure vessel so that the flash evaporation occurs within the vessel, then the vessel is often referred to as a flash drum. [1] [2] If the saturated liquid is a single-component liquid (for example, propane or liquid ammonia), a part of the liquid immediately "flashes" into vapor.
