The power of a flash unit is usually measured by a information quantity (GN), with the formula GN = distance X f-number. Don’t must memorize that by heart, as it's also generally understood that the higher the GN number, the brighter the flash is… However please do be very cautious with this GN though, quoting from Wikipedia: Information numbers should not an absolute measure of flash power (a property called luminous power) because they're influenced by other variables, notably the camera’s ISO setting (film velocity) and flash protection angle - Wikipedia
Yep, as you might need observed, a better GN can be simply "faked" by altering the f-quantity and ISO setting. For example: - GN 60 @ f/1.4 ISO one hundred - GN 60 @ f/2.Eight ISO four hundred
Whereas both GN are the identical, the one at f/1.4 and site (http://196.43.133.60) ISO a hundred is definitely a extra highly effective flash unit. Guide FLASH Energy SETTING
The AR-15, which designates a rifle platform, not a specific producer's mannequin, remains a controversial weapon. Why? Many people mistakenly imagine that "AR" stands for "assault rifle." In actuality, the AR-15 is a semiautomatic rifle, which implies it fires one spherical with each pull of the set off.

Piezoelectric - Patented by Epson, this technology uses piezo crystals. A crystal is located at the back of the ink reservoir of every nozzle. The crystal receives a tiny electric cost that causes it to vibrate. When the crystal vibrates inward, it forces a tiny quantity of ink out of the nozzle. When it vibrates out, it pulls some extra ink into the reservoir to replace the ink sprayed out.
