What is the difference between 5 optical zoom and 8 optical zoom in a camera?
If you're talking about optical zoom there is no difference other than you will be closer to the viewed object.
If you are talking about digital zoom, the size of the pixels will increase and blur.
Hope that helps!
Where can one buy a secret camera?
There are many different places available where one can buy hidden surveillance cameras. These places include, but are not limited to, stores like Amazon and Ebay.
Do digital cameras have "night vision" capabilities?
No, the canon powershot does not come with a nightvision mode. Inclusion of infrared and, quite expectedly, thermal vision is both cost and size prohibitive for a standard consumer-level device.
Where can one learn about the best security systems?
A local police force may be able to offer insight into the best security systems for your home or business. Neighbours and co-workers can also be a valuable source of information and insight, as can local businesses who have security systems.
Can a analog video cassette recorder record from a digital television?
VCRs do NOT process digital signals, analgue is the only language they understand. Therefore, you need to place before the VCR a device that has a digital tuner plus the ability to convert digital signal to analogue.
Examples of such devices are a cable / satellite set-top box, a digital to analog converter box (the converter box ONLY works IF your digital TV feed is coming from an over-the-air TV antenna, not through underground cable), and a stand-alone DVD disk recorder "with a built-in digital tuner".
Whichever tuner plus converter device you have, connect either S-Video or Composite Video AND RCA (red and white) audio output of the device to the input sockets of your VCR. Make sure that whatever "types" of video and audio connections you make are available on both ends, as output on your tuner/converter device and input on your VCR.
What negative impact does the camera have on the world?
you can't take a bath with it.
actually, in UK nations, cameras are used to protect from terrorists. though, this gives those security watchers, the ability to see what other, innocent people are doing.. in other words, invades their privacy. this is a negative effect if you look at it in my perspective, but everyone has there opinions.
How does photographic film work?
The lens focuses the light on the film. The 'focal length' of the lens determines how large the focused image will appear on the film.
The shutter acts as a light valve. A longer exposure allows more light, and a shorter exposure allows less light.
The iris acts to reduce the amount of light, and it also affects the focus. This is called the 'field of focus'. A smaller aperture in the iris produces a larger field of focus, allowing object closer and farther away from the actual point of focus to appear sharper.
The camera's light meter measures the amount of light coming from the direction of the subject.
A computer in the camera can control the aperture, shutter, and lens focus to make the act of taking a picture completely automatic, needing little thought by the photographer. The photographer is free to concentrate on the subject.
Filters can be used to correct for differences in light source color balance, reflections off of objects, ultraviolet light, and create different artistic effects.
When was the large format camera first used?
Well actually believe it or not it was used for during a porno. true fact

What are the limitations of a digital camera and a scanner?
Depends on what you need to do. A scanner copies an image into a computer and a camera takes a picture of something. Many all in one printers have scanners built in, some are as cheap as $50 on sale.
sasi kiran a japanees scientist invented pill camera in 2001
What would happen if the camera were never invented?
The camera helps us to take pictures of what we cannot express in drawings or maybe also what we can. However, with the camera, we erase all the happy memories one had before as he/she would not remember it as time pass by. However, with presence of a camera, we can always take photos of our special things/times and keep it with us all the time.
What is the difference between a pinhole camera and a slr camera?
Most photographers would consider an slr to be "normal". If it's not an slr or a tlr, then you must be referring to a range finder camera or monorail camera. I presume range finder. Thus the major difference is that an slr system presents to the viewing eye pretty much everything that the lens is bringing to the film (minus the parts where the circular image lies outside the film rectangle). A range finder attempts to do this with a separate small viewing lens usually mounted on the camera face off to one side of the lens. The angle of view of the main lens is not the same as the angle of view of the viewing lens, which is usually not a problem. But if you are close enough to a subject such as a flower and you place the camera according to what you see in the viewfinder, you will be too far off to one side and will get less than the whole flower in the picture. This effect is known as parallax.
How does an Olympus camera compare to other cameras on the market?
Obviously this one is the best cameras.
Olympus PEN E-PL1
* The camera feels solid. I love its Bauhaus style retro design that supposedly harks back to some very collectible Olympus classic model. Well, I'd never seen one, but I like the looks of the E-PL1.
* Picture quality with Panasonic lens is much better than expected. In many cases, IQ is better than my Canon DSLR. Panasonic lens is incredibly sharp while the Olympus colors are gorgeous
What is some good surveillance equipment to purchase?
Surveillance equipment is a good idea to invest in. It is especially useful when you have a small business or valuables on your property. I would suggest getting exterior cameras and possibly interior ones as well. Many surveillance systems these days enable you to keep an eye on your home/business from your smartphone. Going on Ebay or Amazon, you could find these for cheaper than if you were to go through a manufacturer or retailer specifically geared toward security equipment.
Where can a person go to get tips on installing a home CCTV system?
People may find information on home security surveillance systems by contacting several home security providers. In order to find these providers, simply search it up on the internet. They will come and install whatever is needed.
How was the camera obscura used to help artists?
The camera obscura was a very early form of a device now called an "opaque projector". By looking at an image of a 3-dimensional object projected onto a sheet of paper, an artist could more closely reproduce its details.
The use of a camera obscura is considered by some artists to be a form of "tracing" so its use as an artistic aid wasn't always well-publicized.
*I would offer that the reason had more to do with reproducing perspective as accurately as possible when representing 3 dimensional scenes on to 2 dimensional art. At one time in the artist's world, perspective was of utmost importance because there was a sector of artists and collectors that concerned themselves (perhaps too much) with spatial relationships. Two renderings of the same scene could be interpreted by the artists in different ways. So how to know which was "right". They thought the answer lay in the use of the camera obscura, which enabled the artist to render the scene on paper, thus capturing the "real" perspective.

The Last answer you had was terrible, if you would like a better one, you should be glad that i found this question.
Definitions of lens on the Web:
- a transparent optical device used to converge or diverge transmitted light and to form images
- genus of small erect or climbing herbs with pinnate leaves and small inconspicuous white flowers and small flattened pods: lentils
- (metaphor) a channel through which something can be seen or understood; "the writer is the lens through which history can be seen"
- biconvex transparent body situated behind the iris in the eye; its role (along with the cornea) is to focuses light on the retina
- electronic equipment that uses a magnetic or electric field in order to focus a beam of electrons
