What is the best digital camera?

The best camera is the one that captures the pictures you want to take.

If you are often mobile and active a sports camera that is sturdy and has good weather/shock protection is great. If you are a studio photographer who takes images of still objects or insides of buildings and you need a great amount of detail a larger format camera is good (there are some VERY expensive cameras made that have fantastic abilities for example the Sinar)

How many pictures can 2 tera bytes hold?

That depends how big the picture files are. A small mobile phone .jpg may have only 20 KB, a TIFF or RAW from a high-end professional camera will have dozens of MB. Once you have got the files into PSD, each composite picture may have a file size of hundreds of MB. A terabyte is 1000 gigabytes.

What was the first mass-marketed camera?

Generally agreed to be the Kodak roll film camera, invented by George Eastman who eventually formed Eastman Kodak Company.

How a lens is made?

First they must make the glass. Optical glass is made by melting specially selected sand and various metals to set the "refractive index" - the way the glass bends light when it's made into a lens. This sometimes takes weeks to get the glass exactly the way they want it. Then there are a couple of ways to form the glass into lens elements. One was invented by Minolta, and involves pouring the glass into molds that have the proper curvature already cut into them. This is how most lenses are made. Really good lenses are made by a technique invented by Nikon. Optical glass forms bubbles when you pour it. They don't affect the performance of the lens but they look bad and at the prices Nikon charges that's not a good thing. So...one of Nikon's fine engineers said something like, "why don't we let the glass harden in the pot, then shove the pot off the roof?" They tried it...perfectly flawless pieces of glass, after they got done picking them all up. This, needless to say, is only used on really expensive lenses. (Zeiss pours their lenses into molds with flat tops and bottoms, inspects the finished blanks and throws the ones with bubbles back in the pot.)

After the elements are ground and polished, they are coated with extremely thin layers of metals. This is the antireflection coating and it does two things for you: lets more light through the lens and gives the lens that neat greenish color camera lenses have.

A lens barrel is produced to hold all the elements, plus the diaphragm and sometimes the shutter. All those parts are assembled into a finished lens.

After the lens is tested to ensure it meets the manufacturer's specifications, it is boxed and shipped.

Is something wrong with the Polaroid camera if the position of the picture taken from it is different from when is seen through the lens?

The polaroid cameras I've seen have had two separate beam paths, one for the view finder and another one for the optics that actually take the picture. If yours is like that, with the viewfinder basically a hole through the top of the camera, then it is as it should.

What security should I look for when searching for off site storage for my household items while I am in the military?

When searching for storage units look for basic security like fences along the permineter. You should also see if the facility has security cameras in place.

Will chinon slr lenses fit digital camera?

Chinon lenses are either M42, 'Pentax screw.' which can fit any digital body with the relevant adapter, or Pentax K bayonet which will fit Pentax or (most) Samsung SLRs.

NB they will only meter stopped down to the taking aperture, and offer neither autofocus nor shutter priority/programmed modes.

There is also the fact that film SLR lenses need longer focal lengths than their digital cousins due to the sensor being smaller, thus a 50mm standard lens for film is a short telephoto for digital.

How did Alexander gardner use the camera to lie hint look for a harvest of death what did he want viewers to think about confederate soldiers what did he want viewers to think about union?

Alexander Gardener used his camera to "lie" by moving some of the dead bodies of soldiers around after the Battle of Gettysburg. He did so because he wanted to make a dramatic picture. He wanted viewers to think that the Confederate troops suffered a dishonored, lonely death in a battlefield while the Union troops had a calm, and peaceful death.

What are some cheap photography schools?

Instead of going to a classical college, there are many more alternatives to photography schools. You can take free online tutorials and online courses that will help illustrate some principles of photography. Other alternatives are skipping a college and looking for local teachers and local photographers in your area who will teach you. Fees for private or group local lessons are much, much less than those of bigger institutions.
