Cameras

411 pictures at the highest resolution - I just bought a sony cybershot and a 2gb card, and my husband was able to look in the menu of the camera to see exactly how many pictures were left.

The invention of photography is subject to some debate. Joseph Nicephore Niepce(1765-1833) created the first photograph on a glass plate using a camera obscura in 1826. His associate Louis Daguerre(1787-1851) invented the worlds first widely used photographic process, known as the Daguerreotype in 1839.

At the same time in England, William Fox Talbot (1800-1877) was attempting to create a permanent record of an image, he announced his calotype process in 1841. The English claim to have truly invented photography since Fox Talbots's was the first negative-positive process from which any number of prints could be made.

Camera obscura, it was created in early china, the theory was that if you seal a box and it's pitch black in side and you poke a hole the image would be upside down, this came to be true. Then deguerre found out that silver nitrate turns black when you put it in the light, aka how we get film, hope I helped!

Photography at has been one of the many ways of recording moments in time. It holds a certain power of above written word, it leaves more up to interpretations while providing a more sold record of occurences. it also serves as an art form, the world being the canvas and light being to paint.

A digital camera is an input device because it captures information and stores it on the device via the memory card(which is a storage device).

Film and photos are developed in a darkroom.

1. Plug your i-pod into the USB cord, and it should turn off.

If that doesn't work,

2. Wait for your battery to die then the screen will shut off once the battery is dead.

3. Try holding the home & on/off button for at least ten seconds. It should turn off. (You might have to try it a few times)

If all fails, (which it shouldn't), call the Apple iPod store, and you can either bring your iPod in or they'll tell you what to do.

It saved people from having to draw images they want which could take several minutes or hours to draw.

Photography is used at crime scenes to preserve the natural evidence. For example: if person J was shot in the stomach, but was place laying on the bullet wound, the CSI, person M, would take a picture of how the body lay and how the items were placed around the body before turning it over. Thus, they have photographic evidence.

To get the film out, if its not already done you will have to wind the film in. Under the camera there should be a small button, press that in. Now, at the top of the camera (usually on the left) there should be a winder to reel the film back in, as i said if the film is still stretched across the camera reel it in, you will be able to feel the film coming back as it suddenly gets loose, keep reeling for 5 seconds just to be sure that the film is in the canister.

Now with the winder on the top of the camera, pull it straight up. It may feel as if it were going to break or not do anything but keep pulling, it should come up relatively easy. One this happens the back should pop open and you can just tap the canister out.

Store it in a cool dry place until its ready for developing.

mmm well wat can i say sum places tht r dark or dangerous for people n in grand concourse

Autofocus is that great time saver that is found in one form or another on most cameras today. In most cases, it helps improve the quality of the pictures we take.

What is Autofocus?

Autofocus (AF) really could be called power-focus, as it often uses a computer to run a miniature motor that focuses the lens for you. Focusing is the moving of the lens in and out until the sharpest possible image of the subject is projected onto the film. Depending on the distance of the subject from the camera, the lens has to be a certain distance from the film to form a clear image.

In most modern cameras, autofocus is one of a suite of automatic features that work together to make picture-taking as easy as possible. These features include:

Automatic film advance

Automatic flash

Automatic exposure

There are two types of autofocus systems: active and passive. Some cameras may have a combination of both types, depending on the price of the camera. In general, less expensive point-and-shoot cameras use an active system, while more expensive SLR (single-lens reflex) cameras with interchangeable lenses use the passive system.

Active Autofocus

In 1986, the Polaroid Corporation used a form of sound navigation ranging (SONAR), like a submarine uses underwater, to bounce a sound wave off the subject. The Polaroid camera used an ultra-high-frequency sound emitter and then listened for the echo (see How Radar Works for details). The Polaroid Spectra and later SX-70 models computed the amount of time it took for the reflected ultrasonic sound wave to reach the camera and then adjusted the lens position accordingly. This use of sound has its limitations -- for example, if you try taking a picture from inside a tour bus with the windows closed, the sound waves will bounce off of the window instead of the subject and so focus the lens incorrectly.

This Polaroid system is a classic active system. It is called "active" because the camera emits something (in this case, sound waves) in order to detect the distance of the subject from the camera.

Active autofocus on today's cameras uses an infrared signal instead of sound waves, and is great for subjects within 20 feet (6 m) or so of the camera. Infrared systems use a variety of techniques to judge the distance. Typical systems might use:

Triangulation

Amount of infrared light reflected from the subject

Time

For example, this patent describes a system that reflects an infrared pulse of light off the subject and looks at the intensity of the reflected light to judge the distance. Infrared is active because the autofocus system is always sending out invisible infrared light energy in pulses when in focus mode.

It is not hard to imagine a system in which the camera sends out pulses of infrared light just like the Polaroid camera sends out pulses of sound. The subject reflects the invisible infrared light back to the camera, and the camera's microprocessor computes the time difference between the time the outbound infrared light pulses are sent and the inbound infrared pulses are received. Using this difference, the microprocessor circuit tells the focus motor which way to move the lens and how far to move it. This focus process repeats over and over while the camera user presses the shutter release button down half-way. The only difference between this system and the ultrasound system is the speed of the pulse. Ultrasound waves move at hundreds of miles per hour, while infrared waves move at hundreds of thousands of miles per second.

Infrared sensing can have problems. For example:

A source of infrared light from an open flame (birthday cake candles, for instance) can confuse the infrared sensor.

A black subject surface may absorb the outbound infrared beam.

The infrared beam can bounce off of something in front of the subject rather than making it to the subject.

One advantage of an active autofocus system is that it works in the dark, making flash photography much easier.

On any camera using an infrared system, you can see both the infrared emitter and the receiver on the front of the camera, normally near the viewfinder.

To use infrared focusing effectively, be sure the emitter and the sensor have a clear path to and from your subject, and are not blocked by a nearby fence or bars at a zoo cage. If your subject is not exactly in the middle, the beam can go right past the subject and bounce off an undesired subject in the distance, so be sure the subject is centered. Very bright subjects or bright lights can make it difficult for the camera to "see" the reflected infrared beam -- avoid these subjects when possible.

Passive Autofocus

Passive autofocus, commonly found on single-lens reflex (SLR) autofocus cameras, determines the distance to the subject by computer analysis of the image itself. The camera actually looks at the scene and drives the lens back and forth searching for the best focus.

A typical autofocus sensor is a charge-coupled device (CCD) that provides input to algorithms that compute the contrast of the actual picture elements. The CCD is typically a single strip of 100 or 200 pixels. Light from the scene hits this strip and the microprocessor looks at the values from each pixel.

The microprocessor in the camera looks at the strip of pixels and looks at the difference in intensity among the adjacent pixels. If the scene is out of focus, adjacent pixels have very similar intensities. The microprocessor moves the lens, looks at the CCD's pixels again and sees if the difference in intensity between adjacent pixels improved or got worse. The microprocessor then searches for the point where there is maximum intensity difference between adjacent pixels -- that's the point of best focus. Look at the difference in the pixels in the two red boxes above: In the upper box, the difference in intensity between adjacent pixels is very slight, while in the bottom box it is much greater. That is what the microprocessor is looking for as it drives the lens back and forth.

Passive autofocus must have light and image contrast in order to do its job. The image needs to have some detail in it that provides contrast. If you try to take a picture of a blank wall or a large object of uniform color, the camera cannot compare adjacent pixels so it cannot focus.

There is no distance-to-subject limitation with passive autofocus like there is with the infrared beam of an active autofocus system. Passive autofocus also works fine through a window, since the system "sees" the subject through the window just like you do.

Passive autofocus systems usually react to vertical detail. When you hold the camera in the horizontal position, the passive autofocus system will have a hard time with a boat on the horizon but no problem with a flagpole or any other vertical detail. If you are holding the camera in the usual horizontal mode, focus on the vertical edge of the face. If you are holding the camera in the vertical mode, focus on a horizontal detail.

Newer, more expensive camera designs have combinations of vertical and horizontal sensors to solve this problem. But it's still the camera user's job to keep the camera's sensors from being confused on objects of uniform color.

You can see how much area your camera's autofocus sensors cover by looking through the viewfinder at a small picture or a light switch on a blank wall. Move the camera from left to right and see at which point the autofocus system becomes confused.

when did film photography start?

1884- Flexible Film

With the Eastman dry plate co. and flexible film

1. The Eastman Dry plate company established in 1879. American George Eastman invents and patents a coating machine for mass-producing gelatin dry plates. In 1881 Eastman and a family friend form the Eastman dry plate co, which eventually leads to the Eastman-Kodak Company

2.George Eastman then introduces the "Kodak" box Camera for the amateur market. It is loaded with 100 exposures on a film roll for $25. It is simple to operate with a three-step process. Once exposed, the camera and the film are sent back to the Eastman Dry Plate and Film Co. for developing.

Features a wooden box covered in morocco leather with roll holder and revolving exposure indicator.

The marketing slogan, "You press the button, we do the rest"

Despite much speculation the word "Kodak" has no significance or meaning. Eastman simple invented a word that begun and ended with his favorite letter, k.

The first multiplane camera was completed in 1937. Its inventor was actually William Garity, a Walt Disney Studios employee who led the team of engineers responsible for the development and building of the multiplane camera. It was Walt Disney's ideas that put the project into motion. Walt was awarded the patent in 1940.

It was the first of the Kodak cameras, dating from 1888. As far as I know it was simply called the Kodak camera. It was a box camera loaded with enough roll film for 100 exposures. In the very early days one coudln't change the film oneself. One had to send the camera to the Kodak Company (in Rochester NY). The developed the flim, made prints, inserted new film for 100 shots and returned the whole lot to the sender. (The Kodak Brownie was introduced in 1900). Incidentally, the invention of roll film was essential for the development of motion pictures.

Frame has several related meanings.

First, the photo frame you buy from the drugstore or department store.

Second, in photo editing it means that a picture is to be cropped and rotated.

Third, it can mean a border around the edges of a photo.

In video, a frame is one photo in the series of photos that create the motion picture. A frame is one image which lasts (typically) 1/30 of a second. 1/15 and 1/8 second are also common.

In 35mm roll film, a frame is one 35mm by 24mm rectangle which is one full sized image or a "full frame." To save film, some compact cameras from the 1950s and 60s used half frame (18mm x 24mm) negatives.

The frame counter counts the number of exposures you have left on a roll of film, or on your digital media.

In summary, the answer depends somewhat on context.

in the bottom right hand corner, in the open space between the playground and the coffee shop for humans, there is a man in red pants and a blue shirt, and red gloves. the camera is in between his legs.

That all depends on where you are talking. If you just mean in general i have no idea. Many stock photo sites will show you the top searchese for photographs on their site. Check these for example: http://www.Smilelikeumeanit.com/stock.html

The rating mAh is a measure of the amount of energy that can be stored in a battery. The higher the number, the more energy can be stored. Assuming that the batteries are the same physical size and have the same nominal voltage, there is no reason why a 1400mAh battery shouldn't be used in place of a 760mAh. The only difference is that the larger battery will last longer between charges than the smaller one.
