Can you take cameras to the Kenny Chesney concert?
Sometimes artists or bands themselves forbid cameras at their concerts, and nearly all forbid video cameras (hurray for cell phone technology!), but a lot of the time it's a choice of the venue they are playing. Some theatres, arenas, etc. do not allow them for certain events. I recommend checking with the place you are seeing him perform. And, just so you know, the 3 times I've personally been to a Kenny Chesney concert, there were plenty of flashes, so I'm sure he's OK with it. Hope I gave you what info you needed.

What part on a digital camera makes the lens move in ond out how does it work?
There are two possibilities;
The focus - a motor moves the lens elements in conjunction with a sensor to get a sharp image.
The zoom - operating the zoom controls, moves an optical group which gives the photographer the desired angle of view.
How do you disassemble a C770UZ Olympus camera?
Ask a professional. If you do it yourself, you'll never get it back together again.
The principals are the same. If you use an old lens on a new body or vice versa you will lose the autofocus function. Also many digital cameras have smaller sensors (known as cropped). So a 50mm lens on your SLR will be about a 78mm on your DSLR because the image is being projected onto a smaller space. This may be a benefit if you use long lenses for sport / wildlife but not if you generally use fish eye! You can now buy full frame DSLRs that are equivalent to 35mm so the lens would not alter. Also lenses are constantly evolving with better glass to prevent chromic abberation, etc and with built in image stabilisation, etc.
Why does the lens flip and decrease the size of the picture in a camera?
The lens is convex (curved outward). Light entering the lens from the outside is refracted (bent) as it travels through it. This brings the image to a single (focal) point. The distance between the lens and the back of the camera is such that it allows a small image of the photographed scene to be visible (the picture). The image is inverted because of the refraction of light through the lens.
Only if you are using a pinhole camera.
If you reduce the aperture you will increase the depth of focus, but you can't decrease the aperture to a pinhole on most cameras.
Who invented the flashbulb and what did it replace?
The first modern photoflash bulb or flashbulb was invented by Austrian, Paul Vierkotter. Vierkotter used magnesium-coated wire in an evacuated glass globe. Magnesium-coated wire was soon replaced by aluminum foil in oxygen. On September 23, 1930, the first commercially available photoflash bulb was patented by German, Johannes Ostermeier. These flashbulbs were named the Vacublitz. General Electric produded a flashbulb called the Sashalit. Flashbulbs replaced flashlight Powder. Flashlight powder was invented in Germany in 1887 by Adolf Miethe and Johannes Gaedicke. Lycopodium powder (the waxy spores from club moss) was used in early flash powder.
Do you need ink for a Polaroid camera?
No, it's not like printing. The principle is comparable to the old-fashioned developing of photos in baths with chemicals in a dark room. Only here each Polaroid film pack that you buy is an envelope that contains all the chemical layers to expose, develop, and fix the photo.

Are eyelids on a human equivalent to shutters on a camera?
No, they are not equivalent. The only thing they have in common is that they block the image. I didn't say 'block light' because quite a bit of light can pass through the eyelid if you are in a lit place, and that is normal. A shutter would be worthless if any light at all is let through the shutter itself. There is a little more similarity between eyelids and video cameras.
Eyelids keep the eyes lubricated and can help brush away very small particles of dust or debris, especially with the help of tears. Also, when the eyelids are closed, the brain instantly begins to relax a little, since a huge amount of information passes to the brain through virtually constant visual stimulation during the day.
Shutters are designed to keep ALL visible light away from the light sensitive surface until the photographer decides to capture an image- a static image in the case of single lens reflex or similar cameras. Then the shutter is opened for a (usually) very brief period, typically a small fraction of a second. Then when it closes it remains closed until the photographer is ready to capture another image.
The light sensitive part of the eye is not like the film or plate of a single lens reflex camera. The retina picks up and transmits continuous action and passes it directly to the brain. In other words, in life we see things as they happen in very close to 'real time'. The film or light sensitive plate in a single lens reflex camera is designed to capture a static image; all the light that hits the surface creates a single image, even if the surface is exposed for a considerable length of time. That is why a too slow shutter speed for shooting conditions produces a blurry image, and it is why 'double exposure' was a common problem when film was the standard medium.
In the case of video, the shutter remains open for as long as the continuous data from the light sensitive surface is sending data to memory, then it closes. When it closes it remains closed and no light enters until the videographer chooses to capture more action. So there is something in common between the eyelids and the shutter of a video camera, but they are still far from being equivalent.
