Lenses used in photography are round, so why aren't photos round?

Answer 1

The photo could be round but then it would waste alot of photopaper. It's easier to put a lot of squares together and get a solid line but a row of circles would have alot of wasted space.

The camera just takes a rectangle picture from the middle of the circle and ignores the rest.

Answer 2

The image projected is more or less round (think of a 3-d ray diagram) but we humans like things that are rectangular. We could have round doors, round beds, round other things but we like to build rectangles. Origin of photography was glass plates and later plastic film, they were square cause its alot easier to make squares or rectangles than circles and square frames are easier to make. The image from the lens in projected onto a piece of film or CCD and the image comes from there. The film or CCD is rectangular, so you get such an image

Answer 3

The film isn't round, its rectangular, only the lens is round. If all of the light used from a round lens made a round picture, the outside would be blurry, like in a telescope.

Answer 4

The lens is round, but the film or light capturing CCD chip is rectangular. Some of the light from the lens goes outside the boundaries of the film/CCD. I guess it would be very inconvenient to make round film or round CCDs. Note that many really old pictures (say from the late 1800's) are round, because they used larger plates.

Answer 5

Lenses have to be round to bend light to hit the film correctly. Light is gathered by the lens and is focused onto the flim, much like the lens in our eyes.

Answer 6

Th projected image from the lens is circular. The rectangular film capture only a portion of the lens projected image. One could make a rectangular lens which will work fine. But making a circular lens may be cheaper and look nicer

Answer 7

There extremely isn't any proper answer for this question because it is going to variety from photographer to photographer. If someone shoots more often than not landscapes they are going to use wider perspective lenses. yet somebody else who more often than not pictures activities or birds will frequently use longer telephoto lenses. For me i want countless lenses that disguise each thing from huge perspective to telephoto because I shoot a large style of topics. If I had an infinite funds, which regrettably i do not, i'd have a kind of correct lenses, particular Macro lenses and some lengthy quickly telephoto lenses. yet because I don’t I genuinely have invested in a good compromise of four lenses that disguise from 18mm as a lot as 500mm. even as there are different correct lenses and some swifter lenses that i wish to characteristic at some destiny date those 4 lenses have served me nicely for numerous years and cover a large spectrum of focal lengths. (18-55mm, 70-210mm F2.8, seventy 5-300mm, 50-500mm). in case you're purely starting up out or don’t have distinct money to make investments in dedicated correct lenses or a large style of lenses i'd recommend you verify out different new “large zooms” which have focal tiers that disguise from between 18mm-250mm (or similar tiers). those lenses make large “walk-round” lenses because they disguise a large spectrum of focal tiers from huge perspective to telephoto. This makes them very versatile or maybe as they could not be as sharp as s correct lens at a particular focal length the known of those kinds of zoom lenses have superior dramatically in modern-day years and they do a very passable interest throughout the time of their focal variety.

Answer 8

Lense is used to view the image.not to get the image ,image is clicking on the photo film.

Answer 9

Film is square/rectangular
