Why does yellow or green eye Occur on dogs when you use a flash on a camera?
For humans, when you flash the cam, red eye occurs. That's because the flash passes through the eye and is reflected off the retina and the blood vessels of retina impart the red colour to the out coming reflected light. More detailed: You see an object when light reflects off it. The colour of the object is the colour not absorbed by it from the incident light. Blood is red because it does not absorb red colour. When you send heavy light in the form of a flash, a large magnitude of red colour goes unabsorbed and the eyes' reflected light's red component becomes significant which is noted as red eye. If there is no flash, the atmospheric light getting reflected off the retinal blood vessels is not intense enough forthe red component to be distinguishable from the other lights. Similarly, dogs and cats have a tapetal layer in addition to retina. And this tapetal layer is of green or yellow colour depending on the animal species. The flash passes through the tapetal and retinal layer. The colour of the tapetal layer is imparted on the reflected light.
What does a flash on a camera do?
Old flash bulbs contained a lot of jumbled tungsten, zirconium or aluminum wire housed in an oxygen atmosphere that was rapidly burnt when the shutter was clicked. Early amateur cameras supplied the current by battery. Later, simple point and shoot cameras like the Kodak Instamatic used something other than a battery (probably a piezoelectric device like a barbecue starter, but I'm just guessing). The bulbs were blue coated to balance the light for color film, and some contained a blue dot to indicate the oxygen had not leaked out and been replaced by air. If an air contaminated bulb was used, it usually exploded. Some cave photographers prefer the flash bulb to an electronic strobe, claiming the quantity of light output is superior. However, bulbs are getting harder to find.
What external flash will fit a Canon Rebel XSi camera?
Any standard hot-shoe flash should fit the XSi, though check the flash sync voltage to be on the safe side. Using a Canon EX-series Speedlite will give you a variety of additional features; other flashes won't be able to synchronise at shutter speeds faster than 1/200th sec, and won't work in live view mode, either, for example.
How are reflective surfaces such as silverware photographed?
If you need to use flash, try standing as far away from the object as possible and use the camera to zoom in. It will help diffuse the light. Most digital cameras are actually pretty good for indoor lighting with out using a flash. The other problem encounter is that you will show up in the reflective surface of the silver. Try photographing at an angle.
Is there any known thing that accelerates faster than light?
Yes, indeed there is. When I get up off the sofa and walk into the kitchen for a glass of milk, I have accelerated at a higher rate than the acceleration of light, since the speed of light is constant and it doesn't accelerate. ***** If, on the other hand, you're asking if any object has a speed higher than the speed of light, then the answer is a little more subtle. Relativity makes it clear that no object carrying information can travel faster than the speed of light. Until a few months ago, this "speed limit" seemed pretty safe. Recent experiments at CERN suggest neutrinos going to Italy at a rate faster than the speed of light, but even the CERN experimenters admit they have probably made an error. It's just that nobody's been able to find the error yet.
Why does your front signal light blink faster than the other?
Check the back signal light. Usually if the front blinks fast the back is out or need to be replace. Vice versa
Who is faster quicksilver or flash?
flash is faster because he has broken the speed barrier lots of times and quicksilver has not so that answer's your question, also DC and Marvel showed a race between them in DC vs. Marvel comic book series.
Why my 2000 Honder Civic's front signal light does not work when I turn on the head light. But if works when I use as signal light?
The bulb has two filaments in it. 1. The parking light filament might be burned out. 2. The ground connection to the bulb might be bad (corroded socket?). This will make that signal light flash oppositely to the other signals when the headlights are on.
What is a T flash?
T flash is a NOn volatile memory it is very faster than the other flash..!
Who is faster sonic flash or sonic?
Flash is faster than sonic by a long shot, he can run through walls and solid objects. Also when he is using speed force he is invincible and becomes 10 times faster than sonic. To add on if they were to race each other at their normal form and starting speed, which for sonic is sound speed and for flash is light speed the flash would thrash sonic.(say it did answer your question if you think flash is faster and say no if you think sonic is faster)
How can you fix the turn signal on a 1990 Buick Park Avenue?
You did not mention if it is a bulb problem or it will not flash. If it blinks faster on one side than the other, then you have a bad bulb. Check them and determine which is not working and replace it. If the indicator stays on steady, then you have a flasher problem. it will not flash
What are fireflies looking for when they flash their lighted abdomens at night?
What fireflies are looking for when they flash their lights are mates, but there are other reasons as to why they would flash their lights. They flash their lights as a survival method telling their predators that the chemicals in their light has a very bitter taste. They also use their light as a warning to other fireflies to stay away.
Why do cops flash a light while driving?
Police officers flash a light while driving to alert other drivers and pedestrians of their presence and to signal for them to move out of the way. This helps the officers navigate through traffic safely and efficiently while responding to emergencies or patrolling the area.
Why does one signal light blink faster than the other?
If you are referring to the blinker indicators on the dash board, it is because one the signal light bulbs need to be replaced. The side that blinks faster is the side where the bulb needs to be replaced. Turn the blinker on and walk around the car to see if it is the rear or front bulb that needs replacement.
Is light faster than sound or is it the other away around?
Light is faster than sound.
Other name of traffic signal?
Stop light is another name for a traffic signal.
Does light or electricity move faster?
Nothing can move faster than light. That should answer this one and several other questions.
