Did you know that you lot can make a working camera out of items that you probably already have lying around the house? While they seem circuitous, cameras are, at the almost fundamental level, dark boxes with a pocket-sized hole for transferring light from an outside subject field to a light-sensitive material. Follow the steps below to make a cardboard or metal pinhole camera.^[1]

1

Choose a cylindrical or rectangular can or box. Selection a container that is well-nigh the size of a normal camera and is clean. For example, you could use an old pigment can, an oatmeal container, a shoebox, or a java can. Be sure that your container has a tight-fitting top.
2
Pigment your container black inside and out. Y'all tin can also comprehend your container completely with aluminum, but be sure to avoid whatsoever violent. Roofing your camera prevents any light reflection from occurring on the inside of the can.^[two]
- Make sure you pigment the entire lid of your container.
- Let the pigment to dry out completely earlier moving on to the side by side step.
- If any pigment fries off before your use your photographic camera, make certain to repaint it before taking whatever photos.

Determine the size of your pinhole. The distance betwixt the film and the pinhole volition impact the effect of your photos. The film will be on the opposite side of the container from the pinhole, then most probable on the hat if you are using a can.
- The size of the pinhole is important because it determines how sharp or blurry your final photograph will be.
- For a container with a 3 to 6-inch distance between each stop, use a No. 10 sewing needle pushed near halfway upward the needle shaft to brand your pinhole.
- Endeavour to make the pinhole every bit make clean of a circle as possible. Twisting the needle equally y'all poke information technology through helps to make a cleaner pigsty.
iv
Make the pinhole in the bottom end of the container. You can either poke a pigsty directly through the bottom of your container using a pin, or you tin can cutting a larger hole about one/2-inch by 1/2-inch out of the bottom of your container and poke a pin through a separate piece of paper or thin metal. The 2d method is ordinarily preferred every bit it allows you to brand a more perfect circle and start over if y'all mess up the first time.
- If you choose the 2nd method, have heavy black newspaper or thin metal and poke the pin through the center of the i/two-inch square. Then secure the piece over the larger hole using strong tape such as electrical tape.
- Sturdy aluminum foil, malleable metal from a food production container, or cardstock all work well for the second method.
- Check that your pinhole is circular by looking through the back of the photographic camera where the picture show will be and peering through the hole. Make sure that you can see whatever is on the other side of the pinhole clearly. A page of printed words works well for determining clarity.

1
Cut a shutter out of nighttime paper. Opaque cardstock that does not allow any light through works all-time for this step. Make sure that the newspaper is thick enough not to fold as it is used.
- Cut a square nearly ii inches by two inches out of the dark cardstock. Make sure that the square is big enough to entirely cover the hole you cutting in the lesser of your container.
- Tape the foursquare to the body of the camera forth one edge above the pinhole. This slice of tape will act as a hinge that allows yous to open and shut the shutter when you want to filter lite.^[3]
- Use whatever type of sturdy record such as electric or duct tape.
2

Put a piece of tape on the bottom of the shutter flap. Use a less-pasty record for this side, (electrical tape works great, duct is too strong) and tape down the contrary end of the shutter underneath the pinhole when you are non taking a photo to prevent light from entering the inside of the photographic camera.
3
Create a viewfinder out of paper-thin. The viewfinder allows y'all to replicate the geometric relationship of the pinhole to the picture and helps you visualize what your concluding photo will wait similar.
- The front viewfinder should imitate the shape of the moving-picture show and be constructed straight above the pinhole. Secure information technology with potent tape or hot glue.
- The rear viewfinder should sit on top of the camera and deed as a peephole that allows you to visualize your photo. You can make a peephole out of a metal washer or cut a perfect circle out of cardboard and attach it to the rear viewfinder. Over again, secure it with strong tape or hot glue.
- For taking photos of subjects closer than 5 feet away, position your subject low in the viewfinder to account for the difference betwixt your perception and the angle of the pinhole.

i
Choose photographic paper or film. If you choose to apply photographic paper, y'all tin can load it into your camera under specific lighting conditions.
- For photographic paper, yous have to load it either under a safelight, or a flashlight filtered through at least three layers of cerise cellophane fastened to the lighted end.
- The flashlight must be six to eight feet away, then hanging it from a ceiling and working underneath it is a adept way to achieve this distance.
- Different photographic paper, flick must be loaded under completely dark weather condition. Practice loading your camera with a simple piece of paper in lighted conditions, and so with your optics closed to get the feel of loading the movie earlier you lot try to do then in complete darkness.
ii
Determine the size of your calorie-free-sensitive material. Y'all will have to cut the flick down into smaller frames. The size of the frame will depend on the overall size of your camera's body.
- For well-nigh moderately-sized cans, you can use a strip of flick cutting into 2 3/eight to 3 ane/2-inch pieces. For a camera made from a one-gallon paint can, cutting a 4 by 5-inch piece of movie. A camera fabricated from a 2-pound coffee can will take a 2 1/iv by 3 one/iv-inch slice of film. These measurements apply to the use of photographic paper every bit well.
- Use canvas motion picture if possible, which is easier to dispense equally it is completely flat.
- Brand certain to cut down your paper or moving-picture show in complete darkness. A closet should work fine as long as no cracks let calorie-free to seep through.
- If you are unsure nearly the ratio between the size of your picture show and the size of the photographic camera body, err on the side of cut too big of a strip of light-sensitive textile. Y'all can ever trim downwards the edges of your photo later on you develop information technology.
3
Load your photographic camera. Place the photographic paper or film on the inside of the camera, reverse the pinhole.
- In total darkness, secure the film or paper from the back using a piece of tape rolled into a loop. Y'all may need to place record in each corner of the film in order to prevent it from rolling up. Do non place any tape on the front side of the pic or paper, every bit this may crusade damage and obstruct the image formation.^[iv]
- Make sure that the emulsion side of the paper is facing the pinhole. You lot tin can tell which side is the emulsion side of photographic newspaper from its shiny advent. The emulsion side of film is the side rolled up on the within of the spiral equally you unfurl information technology.
- If you lot are having trouble determining the emulsion side, wet your finger and bear on either side of your paper or film in the corners. The side which feels glutinous to the touch is the emulsion side.

1

Place the camera on a flat surface. You tin either simply set it on a table, counter, any other completely apartment surface, or adhere it to a tripod using rubber bands or tape. Because of the sensitivity of the shutter, y'all need the camera to be extremely still every bit you take photos.
2
Decide the exposure time. For film, you only need to expose the camera to light for a few seconds, but photographic film can take up to a few minutes.
- If using picture, the duration of exposure depends on the ISO of the pic. The higher the ISO, the shorter the exposure time. For 400 ISO film, you volition expose it to light for between two and 12 seconds depending on the brightness of the external light. For 100 ISO pic, the exposure time can range between eight and 48 seconds, and for l ISO motion picture, the exposure time may range between 16 seconds and ane infinitesimal and 36 seconds.
- If using photographic newspaper, the exposure fourth dimension will well-nigh likely range from ane minute to several minutes, though in that location are photo paper products made specifically for longer exposures, even upward to several months!
- You volition have to practice to determine the exposure fourth dimension that works for y'all, but think the general rule of thumb for exposure time: the brighter the external light, the shorter the exposure time.
3

Betoken the photographic camera at your subject. Remember to account for the distance betwixt the pinhole and the viewfinder by aiming a bit lower than you might perceive.
4
Open the shutter flap. Pull the lesser tape up to permit light to stream through the pinhole. Do so very carefully so as not to shake the rest of the camera.
- If your exposure time is several minutes or hours, you lot can carefully tape the shutter open so that you don't have to hold it open manually.
- You tin can also place some sort of weight such as a rock or a shoe on meridian of the camera if it is windy where you are photographing.
v

Close the shutter. Once you lot've held the shutter open for the desired exposure time, retape the flap downwards to prevent any more than low-cal from inbound through the pinhole. During the time that the shutter was open, an prototype was created on the film or photographic newspaper. All that's left to exercise is develop your photo.

Gather your developing materials. In improver to a darkroom, you will demand developer solution, fixer solution, h2o, tongs, towels, a canvas of drinking glass, and a prophylactic light in you dark room. Your darkroom must be completely blackness other than having the safe calorie-free on.^[5]
- You lot tin also employ orange LED halloween bulbs every bit safe lights.
- Yous will also demand three plastic dish washing tubs. Make full 1 with about ii inches of programmer, the second with near two inches of water (called a stop bath) to end the developing process, and the third with logroller solution.

Apply a photograph enlarger to transfer the negative to photo paper. If yous used photo paper in your camera instead of film, skip this step. Otherwise, identify your negative on the negative slide, plough the enlarger on, and cull the appropriate f/stop for your photo.
- Yous may desire to create a contact sheet to test out different f/stops before settling on an f/terminate. Practise so past covering the paper with a piece of blackness cardstock and gradually uncovering it while changing the f/cease in order to create strips of different brightness.
6
Identify your photo paper into the developer. Once you lot have transferred the negative image to photo newspaper, place it in the developer using a pair of tongs. Watch as the image appears on the newspaper and take the image out of the solution using tongs as soon as information technology is as dark every bit you want information technology to be.[^[6][Image:Make a Pinhole Camera Step 22.jpg|heart]]
- Gently stone the tray back and along to spread the solution over the photo newspaper.
- Go along in mind that the image will appear a bit darker in white low-cal once you are outside of the darkroom.

Using tongs, place the photo paper in the logroller for two minutes.
9

Remove the photo and rinse over running h2o for 2 minutes. Allow the photo to hang dry completely or dry with a pilus dryer.^[7]
