Camera lenses must be round to focus light properly. Close one eye and you will notice you see a circular "picture" of the world. Two eyes placed side-by-side gives the impression you are seeing a rectangular view but you are seeing two circles overlapping. Rectangular areas of the film were placed next to each other to maximize the amount of pictures a roll of film could hold. Now that roll film is no longer used rectangular pictures still replicate our perception of vision.

Working principle of digital camera?
Working principle of a digital camera: · Capturing image: lenses focused the light rays come from the object made into a coherent image. Diaphragm determines amount of light to be entered and shutter speed determines time of exposure. Then lights made fall onto sensor (CCD) to get corresponding electric charge. · Binary system processing: Where there is word digital, the word binary also found there. To convert analogue signal (electric charge from photosites) to Digital signal in binary form a ADC converter is used. Each of the charge stored in photosites assigns to a binary value, storing them as pixels. A pixel is a point sample of an image which contains three basic color (RGB) components. Pixel per square inches determines the resolution of the camera, which indicates the size and quality of image. In next post I'll discuss more about pixel and resolution. · Compression and storage: Once the image is digitalized, it is compressed by a microprocessor and stores as image file (JPEG, TTF etc.) From the age of invention of camera, evolution of this has been taken place and which will continue. Now digital cameras are being developed by adding new features like video recording, music playing, even GPS has embedded in it.
How big is the biggest roll of film?
Still camera 200 pictures (Hasselblad 21/4 square format). Cine film runs at 24 frames a second, so a half hour film roll would be 43200 frames.
Suppose a digital camera has a storage capacity of 256 MB.How many photographs could be stored in the camera if each consisted of 1024 pixels per row and 1024 pixels per column?
Given a digital camera has a storage capacity of 256MB. That is, This camera has a storage capacity of = 256 x1024 x 1024 bytes. Since a single photograph consisted of 1024 pixels per row and 1024 pixels per column, then The number of pixels in one photograph is 1024 x 1024 . Since each pixel required three bytes of storage. Thus , A single photograph require the storage of = 1024 x 1024 x 3 bytes Now, The number of photographs could be stored in the camera = ( storage capacity of digital camera) / (storage required by single photograph) The number of photographs could be stored in the camera = 1024 x 1024 x 3 = 3,145,728 bytes per photo => 3,145,728/ 1,000,000 = 3.15 MB per photo => 256 / 3.15 = 81.26 => 81 photos per camera.
How much area can the blackbirds camera photograph in a hour?
The area that a blackbird's camera can photograph in an hour depends on various factors, including the camera's specifications, altitude, and speed during flight. Generally, if we consider a drone equipped with a high-resolution camera, it can cover several square kilometers in an hour. However, specific numbers would vary based on the operational parameters and intended use of the camera. For precise figures, details about the camera model and its operational conditions would be needed.
How much mega pixel camera?
A megapixel is one million pixels. A pixel is a picture element. Like graphics displayed on a television or computer monitor, digital photos are made from millions of tiny colored dots, or pixels. The more pixels used to produce a photo, the less "grainy" it will appear and the better any enlargements made from it will be. A 6-megapixel camera can produce standard 4 x 6 photos at a remarkable 500 pixels per inch and 8 x 10 photos at 273 ppi. A megapixel (MP) is 1 million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.
Why are pictures square if the lens is round?
Pictures are square because most camera sensors and screens are square or rectangular in shape, even though the lens is round. The sensor captures the image in a square or rectangular format, resulting in square pictures.
When you taking the snap the camera lenses are round shape but how the photos are coming in square shape?
The lens is used to focus the light rays onto a square or rectangular shape where it is recorded.
