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 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.
A full-power flash from a modern built-in or hot shoe mounted electronic flash has a typical duration of about 1ms, or a little less, so the minimum possible exposure time for even exposure across the sensor with a full-power flash is about 2.4 ms + 1.0 ms = 3.4 ms, corresponding to a shutter speed of about 1 ⁄ 290 s. However some time is ...
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 wrapped its pandemic-interrupted Mirrorverse arc this Tuesday night. What (or who) did it take to thwart Eva’s plan to create a new, better world for the Mirror Monarch’s “children ...
An opposite effect has been shown to preferentially extract water molecules from the sharp edge of potato wedges in the oven. [8] If a microscopic droplet of water is cooled very fast, it forms a glass—a low-density amorphous ice in which all the tetrahedral water molecules are not aligned but amorphous. [11]
