a pinhole camera is a camera without a conventional lens, instead there is a small hole that allows light to come threw.The aperture has to be very very small compared to what your looking at. The shutter has a flap or a covering that you cover or uncover the pinhole with. This camera has a very large exposure time.it can range from 5 seconds to 5 hours to 5 days, it just depends.

A pinhole camera is a camrera without a conventional lens. it has a small hole the size of a needle point in a thin material and light rays from an object go through the hole focusing on a single point to form an image.

a pinhole camera is a camera without a lens. It is made of a box or canister with an extremely small hole in the side. the small hole takes in light rays and projects them upside downon a piece of photographic/ developing paper. the hole needs to be covered until til of taking the picture. The exposure takes a very long time to develop, so the object being photographed must stay still or the photo will be blurry.

a pinhole camera is a camera without a lens. or well a glass lens. yo put a small pinhole, duh, in a material or product thing. you then put a piece of photographic paper. you cover the hole so no light can get in until you want to tak the picture. you generally want to put it on a hard surface because it can take hours to get a good exposure. unless you make a larger hole but then the image is blurry because the light overlaps eachother. after you take of the coveruing and let it sit you can put the covering back and then go and develope the picture. the picture will be small and if people were moving in th epicture it will have streaks from them.

a pinhole camera is a very simple camera, using light squeezing throiugh a very small hole onto a small pice of photopaper. one method of constructing a pin hole camera is by using a film canister and placing a small piece of photo paper in the bottom in a very dark room then use masking tape to cover the open half and poke a small hole in it...then take this set up and place it somewhere where it wont be budged and let it set for a while. after a long period of time an image will appear on the photopaper after development.
the end.

A pinhole camera can be made from any hollow box can or container that is enclosed and keeps light out. there is a small hole in it that has an infinite depth of feild. a piece of film paper is put at the back of the inside of the camera. a flap will let light in the hole and will be absorbed on the paper
amanda politi 2* i read about the pinhole camera.

I read about the pinhole camera and i think it sounds unique because of the really small hole able to capture good pictures. I also like how the aperture is like a hundred times smaller than the distance to the screen, or less.

a pinhole camera doesnt have a conventional lense. it takes the image and confins it in a small area to get a clear photo.
Jack Collum 2
a pinhole camera is a camera that is completely closed except for a pinhole. the pinhole is the shutter.there is a piece of film in the back of the camera and if you let it sit in light it will expose and leave you a pic on the negative. it takes a long time to expose.

the pihole camera is a camera without a traditional lens.it has a really small aperture.and the shutter is hand operated flap.the exposure is really long because of the samll aperture.

1. It bends twice to flip the image upside down.
2.The angle of light entry change when you zoom in.
3.Sports photographers have a long lens.
4.A 35mm camra.
5.Low
6.Herschel 1839.
7.camera obscura, Latin for "dark room
Nikki Reinert, period 2.
1. Describe how light bends twice when it encounters a lens?
-As light travels from one medium to another and so will start slowing down first, this is somthign pushing at an angle.
2. When does the angle of light entry change?
- It changes when you move the object closer or farther awya from the lens.
3.What Lens has the long focal point?
- Teleohoto Lens
4. What lens has the short focal point?
- Wide-angle lens
5. A higher focal length number indicates a ___real___ image magnification.
6. Who came up with the term camera come from and what does its origin mean?
- Sir Jogn Hershcel, the workd camera comes from the word camera obscura latin for "dark room"
7. Where does the term camera come from and what does its origin mean?
-came from camera obsura latin for dark room.

A pinhole camera is when you take a film canister and poke a very tiny hole in it. this lets some light in to expose the film, but it takes a really long time to get an picture.
Julia Deitz
2nd period
The pinhole camera is a very basic form of a camera and very easy to make. The pinhole camera has no lens and is made up of a thin material in the form of a box with a tiny hole and the film inside. The shutter is just a dark flap of whatever material you choose and stays open until you put the flap back down. The shutter time can be from 5 sec. to a day because it needs more time to get an exposure. The aperature (the hole) needs to be at least 100 times smaller than the actual image.
Hannah 2nd period
The pinhole camera was invented way back in 500 B.C. This is a camera without a glass lens. In a pinhole camera, the light rays from an object pass through a small hole to form an image. Pinhole cmaeras have to have very small apertutres which then requires much longer exposure time. The shutter is usually a hand operated flap of some lightproof material.
Natalie Surckla
2nd Period
A pinhole camera is a camera without a conventional glass lens. The pinhole camera has to have an aperture that is 100 times smaller than the distance to the screen or less. The shutter usually consists of a hand operated flap of some light proof material to cover and to uncover the pinhole. They take long exposure times and they are usually used for taking pictures on the moon and the stars.
Chris Hanford 2nd Period
A pinhole camera is like a regular camera except it does not have a conventional glass lens. The aperture must also be extremly small compared to the distance to the screen. The shutter also is controlled by a hand operated flap made with a light material to cover the pinhole. Pinhole cameras have a very, very long exposure time.
JEff Lengel
2nd period
A Pinhole camera is just like a regular camera but wihout a conventional glass lens.With extremely small hole in a very thin material can focus light by traping all light rays from a single point. The camera produces an extremely clear picture by having a extremely small apeture far from the distance to the screen. The only downfall to the Pinhole camera is that because it has such a small hole it takes a very long time to make an exposure.

1.when the lens is "bowed" outword at a greater angle the light is bent more so it converges closer to the lens
2.when the lens is curved as aposed to flat

a pinhole camera is a box with a tiny hole on one side and a film or peace of photographic paper on the opposite side.The light from the pihole will form a real image.
maximillian j trevino 2nd period
ma pin hole camera is a camera with no lens at all. it works by takeing a small amount of light from a pin hole in the end or side. the light is projected onto a pice of photo sensitve paper. for this reason it must be exposed for a longer period of time.

a pin hole camera is a camera thatdoes not use a glass lens. There is an extremely tiny hole through some material by confining light to a single point. the apereture has to be 1oo times smaller then the distance and the shutter is a hand opperated flap. the exposure tim is usually hours or days unlike the conventional camera because of the small apereture.

A pinhole camera does not have a conventional glass lens. It has a really small hole that can focus light through a single point. The aperture has to be about a hundred times smaller than the distance to the screen in order to produce a clear image. The shutter has a hand-operated flap of some light-proof material the covers and uncovers the pinhole. These cameras require much more exposure time. Images can be projected onto a translucent screen for real time viewing.

The pinhole camera is a camera without a conventional glass lens. In order to produce a reasonably clear image the aperture has to be a hundred times smaller than the distance to the screen. The shutter of the pinhole camera usually consists of a hand operated flap of some light-proof material to cover and uncover the pinhole. Th pinhole camera requires much longer exposure times than conventional cameras' because of the small aperture;typical exposure times can range from 5 seconds to hours or days.
Michelle Zoldan!4*
A pinhole camera does not have a normal glass lens. A very small hole can focus light by converging all rays from a scene to intersect at one point. The aperture has to be about 100 times smaller than the distance to the screen, or less to get a clear image. Pinhole cameras require much longer exposure times than regular cameras because of the small aperture; normal exposure times can range from 5 seconds to hours or days.

A pinhole camera is a camera without a normal glass lens. An very tiny hole in a very thin material can focus light by making all the light rays from a scene come together through a single point. To get a reasonably clear image, the aperture has to be about a hundred times smaller than the distance to the screen, or less. The shutter of a pinhole camera is usually a hand operated flap of some light-proof material used to cover and uncover the pinhole.

A pin hole camera does not have a conventional glass lens. Their is a small hole that captures light inside it. It captures the scene that the box is pointin too and then devolps it. It can expose the picture from 5secs to hours to days.

A pinhole camera is a camera that lacks a conventional lens. Instead, there is an extremely small hole punched in very thin material. This allows it to focus light by confining all rays through a small point. It has a a small aperture and a shutter made of some light proof material over the small hole. it is also hand operated. The exposure ranges from 5 seconds to hours, or even days.

A pinhole camera is an extremely simple type of camera that uses a very small hole as the lens and when the shutter or light proof material is removed from the pinhole the light strikes the film and the picture starts to develop.

how a pin holw camera and what a ppin hole camers is is a small tube like a film hilder and it has a samll hole made by a pin hole. u put it in a room with a light and keep the bottle in the room for a day then u take the paper from in side the botter and u can develop it cause the light is working a a light on one of the machines in the dark room

A pinhole camera is a lensless camera that requires the photographer to use a really small aperture. Sounds pretty hard to use.

not to sure if this posted, but its a simple camera without a conventiional lens. and the photographer has to use a reallly small aperture to have a good negative.
Pin Hole Camera, Rachel Nagy 2nd
The pin hole camera has no conventional lens. The hole is very small and the light is focused by confining rays through it. The aperture is 100 times smaller than the distance to the screen. The shutter is a hand operated flap of light material. The film of this camera requires a much longer exposure, anywhere from 5 sec - days.
