What is the best digital camera for fast shutter speed?

To the best of my knowledge, it is the Olympus E3 at 1/8000 second as of 2008. However, an important measure of digital camera speed is also fps (frames per second) as the camera must meter and check focus and other settings before taking the shot. At present DSLRs can't be beat in this regard. Compact digitals usually suffer from shutter lag. Casio claims the fastest fps at 60 fps, 6.0MP, jpeg as of Aug. 2007. You should denote from this that the fps numbers alone mean nothing unless everyone is using the same yardstick. When have the manufacturers ever done that?

19th century photography pioneer?

Louis Jacques Daguerre, Fox Talbot, Ansel Adams, Margaret Cameron. It's hard to choose, they all came up at the same time, since photography was invented in that century.

When was the first camera introduced to the public?

The use of a lens in the opening of a wall or closed window shutter of a darkened room to project images used as a drawing aid has been traced back to circa 1550. Since the late 17th century portable camera obscura devices in tents and boxes were used as a drawing aid.

How and who was the first camera discovered?

The term camera comes from the Latin "camera obscura" which means dark chamber and was a small box with a mirror inside that would project an image onto a piece of glass. The first camera obscura was probably built by a man called Alhazen in the 11th century. Later, during the Renaissance, many artists like Leonardo Da Vinci used a camera obscura to trace a scene that they would later paint. So, the original camera was used for painting on canvas, not for taking pictures as we normally do now. And even now, the camera obscura is not even a traditional camera, but a microchip in a digital camera.

What controls sharpness and depth of field in a picture?

The longer the exposure the more light is let into the camera, as a result the picture will be brighter/lighter/whiter. The shorter the exposure, the less light let in, and the darker the image will be.

Answer:Aperture can affect the quality of a photographic image in at least four ways.

First, and most well known, as the aperture (the lens opening -- the hole through which the picture enters the camera) gets larger it lets in more light and you can take a picture in darker locations, or you can take pictures at higher shutter speeds thus freezing movement better.

The next most commonly known effect is that the wider the aperture the shallower the depth of field. That is, the fewer things in front of or behind the subject of the picture are in focus. As the aperture gets smaller things further away from the subject in both directions are clear.

Another way aperture can affect the image is that your lens will be sharpest at some aperture. Often somewhere around F5.6 to F8 your lens will make the sharpest (clearest) images. This is called "the sweet spot."

Finally, for technical reasons, at very small apertures (usually F16, f22 or smaller) an optical phenomenon caller diffraction causes the image to become become less sharp. You can think of it that when light must squeeze through a tiny hole the light rays interfere with each other.

What is the importance of photography in advertising?

Photographs are not space fillers in a newspaper as many may think. Photographs are used to make ideas explained in writing more visible and fathomable to the readers.

They are also used as the selling point of any publication in that case meant for such.

A well taken photo is worthy a thousand words, so editors will always have space for photos in their publications.

When was cctv cameras invented?

who invented cctv cameras and what year was the first one invented.

How do you connect cctv camera to a cable television?

Most PC monitors use VGA (DVI is also popular - you can easily convert VGA to DVI with a simple adapter).

Most CCTV camera systems are BNC - all you need to connect your CCTV camera to a regular PC monitor is a BNC to VGA adapter. They can be had for anywhere between ~$40-70.

What does eye level camera angle mean?

Holding the camera at the level of the adult human eye. It's the most common angle used. Try "toddler level" once in a while to remind you of what things used to look like (in my case) decades ago! Try almost ground level sometimes (especially for uncluttered landscapes).

How much is a professional camera?

It Really Does Depend What Your Looking For. If Your New To Photography Than I Would Go With A Kodak z981. (The Camera I Use) It Takes Amazing Pictures! But The Video On The Camera Is... Okay. But If You Want To Take Good Photos I Recommend You Use It Outdoors. Indoor Lighting Doesn't Take Good Quality Photos At All With This Camera. This Camera Is About $300. If Your Not A Beginner And Are Looking For A Truly Professional One The Are Near $1000. Hope This Helps (:

What is the value of a Polaroid Land camera?

Because these cameras are so plentiful, they typically sell at auction for less than $30.00, even in top condition. The most common price is in the $10-20 range, although it's still possible to find a bargain for $5.00 or less.

Other Details

The Polaroid 210 Land camera, manufactured from 1967-1969, is probably the most common folding pack camera on the market. Polaroid sold more than 1.5 million of these at a retail price of $49.99

This model uses Series 100/660 pack film that is still available through Polaroid, Fujifilm and the Impossible Project. Although the cost per shot is a little steep compared to digital (about $1.00) each, the Land cameras are an interesting piece of Americana.

How do they photograph things to make them look bigger?

The only way that we can judge the size of an object in a photograph is to compare it to other objects in the same photograph. Therefore, you can combine two or more photographs, with different enlargements, to create the illusion that some object is larger than it really is. Or you can build small models that look like something bigger than they really are. Or you can use tricks of perspective to make something look closer than it really is.

What are the advantages and disadvantages of light in photography?

I'm going out on a limb, but it seems the only possible disadvantages of light in photography are an improper intensity, amount, quality of diffusion or source position of it, unless you are using photographic materials to capture EMR (electromagnetic radiation) outside of the visible spectrum.

How is the direction of data flow different for data transfers for MP3 players and digital cameras?

MP3 files are downloaded from the PC to the MP3 player, in contrast to a digital camera, which transfers or uploads data to the PC.

I am guessing you are talking about an electronic one?

Please be more specific of your questions next time.

Will digital photography replace film photography?

I believe the answer is yes - once sensors can match or beat film in terms of depth (the range of intensity they can record) and the amount of noise produced. It may occur gradually as die-hard film users retire. But it will happen in my opinion.

The question isn't If! It already has. I mean, you don't see many people- other thna those that are just studying Photography- still using Film SLR's. I've used Film SLR's in the Past, and have completely left it in the dust. From around a year ago, I've been Using Digital SLR's, more convenient, equal image quality, and you aren't limited ( to much ) Who'd rather change rolls of film, when you can shoot 5 Frames per second, and not stop. Digital Photography has already taken over- I can't say film is dead, but suffering from a terminal disease. Manufactures, like Canon, and Nikon, will soon stop Making Film SLR's- So you'll have to shoot Digital.

An Historian and Archivist adds

Although most photographers have made the switch to digital there is still a niche that will remain film based for perhaps the next generation. That niche is archival photography, which includes microfilm and preservation of important legal documents. Not that digital archives are not important, but if a legal question comes up the film record will hold up better in a court of law better than a digital because of the ease of which fraud can be commited with digital imaging.

----------------------- It definitely has already occurred. Film offers no real benefit over digital, and I think the last of the old time pros have switched. Some of them left kicking and screaming, but 99% have migrated. There are some people who "just like film." Some digital cameras now have secure one-way hash functions built into them for evidence preservation where if the picture is altered after the fact, the hash won't be correct. It's not perfectly secure, but I'm sure its designed to address the issue above.

What is meant by parallax of a point on a photograph?

Simple parallax is the angle produced by the difference between the axis of a viewing optic versus the axis of the image forming lens. In non slr cameras (range finders) this is an issue below a certain distance and causes a different image to be captured than what is viewed.

The "no parallax point" is the point around which a camera would have to be rotated when constructing panoramic photos using a series of images, so that when the images are stitched together, there is perfect alignment. Where this point is exactly was a subject of debate. Search "no parallax point" to learn more and decide how to find this point in your lens(es).

When was the first still camera invented?

This is a hard one. While half-plate and quarter-plate SLRs are as old as photography, they were heavy and complex and with the single-shot technology of the time offered no real advantages over contemporary view cameras.

The first commercially successful SLRs were probably the 1930s VP Exaktas, which gave 10 shots on a 127 roll.

The first 35mm SLR was the 1936 Kine-Exacta, a VP model (made by Ihagee in Dresden, Germany) scaled down to take 35mm film, although the Soviet, 'Sport,' was introduced at roughly the same time.

Ihagee of Dresden certainly invented the 35mm SLR from which all modern types are descended.
