How does the infrared cameras work?
Infrared is like light with a wavelength beyond the range of human eyes. It can however be picked up by infrared photographic film and digital sensors (digital cameras usually have a filter to block it out though).
When taking infrared photos an infrared filter is needed in front of the lens to block out the visible light.
Do Polaroid cameras need charging?
No. They do require AA batteries, but those are removable. The batteries themselves may be charged (if designed to do so; please read their manual carefully to prevent injury or death).
How can you calculate the focal length of a lens?
A very simple method to calculate the focal length of a lense is to focus it front of the sun and find out a sharp, small point at ground and you have to calculate the distance between that point and lense.... However this gives you approximate result not very accurate resut... For accurate result you have to go in to physics lab and work with optical bench... Thanks
Who invented the first camara and when?
The first camera invented was a device called the camera obscura (Latin for "dark room"), it was a small room with a pinhole in one wall that was used by artists to make paintings of their clients. The earliest extant written record of the camera obscura is in the writings of Mozi (circa 470 BCE-circa 391 BCE), a Han Chinese philosopher, but they had clearly been in use long before that so that the actual inventor and when it was invented cannot be determined.

Why would a photographer use a pinhole camera?
probably to take a picture of something very bright, like the sun.
In reality, the pinhole camera is not the ideal instrument for taking photographs of the sun. It is used instead to create certain specific effects in the photograph. Light passing through the pinhole is not brought to a sharp focus on the image plane in the same way a lens would, so the sharpness of the image is limited, and dependent on the size of the pinhole, the distance of the pinhole from the film plane, and the amount of diffraction from the edges of the pinhole. Even with optimum sharpness, the image will be very soft, with fairly fuzzy outlines. In the hands of a skilled photographer, the effect can be very pleasing.

How many picture can you store on a 4GB memory card?
The capacity of a card indicates the maximum amount of data that can be stored (less some space for the card's own use).
Megapixel (MP) count refers to the maximum resolution of the camera's sensor -- its ability to record detail. The number of images that can be recorded on a card of a given size is only indirectly related to the capacity of the card, which is measured in Kilobytes (KB) or Megabytes (MB), not MP. That will vary according to the image itself, and to the camera's settings.
For example: My Pentax K10D, with a 10.1 MP sensor and using a 4 GB card, will record approximately 821 images at the highest resolution (10 MP) and a "Fine" setting. The same camera, with the same sensor and same card, will record 10,000-plus images at the lowest resolution (2 MP) and the "Low" setting. Practically all cameras have this ability to change the resolution settings, and thus the sizes of the image files that are stored on the card.
So, you can see that it is only possible to answer your question in very general terms: The higher the capacity of the card, the more images you can store at whatever camera settings. And, as you can see above, even at the highest settings with a high MP count, you can take a lot of pictures!
One thing to think about: storage cards can and do fail. It is better to have two 1 GB cards than one 2 GB card, unless you plan to shoot a whole lot of video. That way if one fails, you can keep shooting and worry about retrieving the images off the other card later.
