What is flash photography good for?
Flash has the ability to freeze the motion in a photo, allowing you to play around with the light trails. This is especially handy if you’re working in a low light situation with just a nasty on-camera flash, as it allows you to produce something cool and creative from very little.
Is flash photography harmful?
Yes, there are ways that extremely bright lights can damage someone’s eyes. However, photography flashes, at least for the vast majority of people in the vast majority of circumstances, aren’t harmful. There is something called “flash blindness,” when the retina gets too much light and you can’t see clearly.
Which gas is used in flash photography?
Argon flash, also known as argon bomb, argon flash bomb, argon candle, and argon light source, is a single-use source of very short and extremely bright flashes of light. The light is generated by a shock wave in argon or, less commonly, another noble gas.
How do Magicubes work?
Magicubes or X-cubes In order to fire the flash, a pin in the cube mount released a spring wire into the cube, that struck a pin at the base of the bulb that contained fulminate ions or fulminating material. Due to friction caused, they caused a small fire which in turn ignited the zirconium that worked as a flash.
Do people still use flash photography?
Flash is still an absolute stalwart of photography, and if you need the power to counter sunlight, or the ability to freeze motion, then it’s the way to go. But if you’re working indoors, and don’t need to use super-fast shutter speeds, two or three LED lamps may provide everything you need.
Is flash necessary for photography?
Can flash blind a bird?
It is safe to say that nocturnal animals, especially birds, will most likely experience some sort of temporary blindness from exposure to flash at night. But this is temporary, and lasting for perhaps 5-20 minutes before the photoreceptors are fully recharged.
What kind of bulb is in a flash?
The use of flash powder in an open lamp was replaced by flashbulbs; magnesium filaments were contained in bulbs filled with oxygen gas, and electrically ignited by a contact in the camera shutter.
How many lumens is a camera flash?
From my brief research online, where a few people had done some basic calculations on camera flash units, it would appear they produce around 200,000 – 1000,000 lumens.
What is a Magicube?
Magicubes are little cubes composed of four individual flash bulbs (one on each side of the cube), backed by plastic reflectors. The bulbs themselves are like little lightbulbs, except that instead of a filament, they’re filled with zirconium foil and oxygen gas.

Do camera flashes hurt owls eyes?
While the damage flash can have on an owl’s vision is not definitively known, other photography tricks have more demonstrable ill effects, such as baiting owls and flushing them from their roosts in the quest to create dramatic images.
Does flash photography hurt spiders?
They can deliver enough energy to the retina to damage it. To damage spider eyes, a light would have to be stronger than sunlight. Cell phone flash photography might involve lasers, but I doubt it. Certainly a cell phone strobe light would not involve a carbon-arc light source.
