What does a pinhole camera look like when its done?

Yes, however you are restricted as to what you can take pictures of. Pinhole cameras must stay on a surface while taking the picture (as to not blur the image), unless you want to produce an image with motion blur you are unable to take pictures of any moving subjects, and the images are not digital; meaning you need to develop the image using chemicals and a dark room.

Traffic ticket running a red light in California on camera?

I made a right turn on red on Friday, got the ticket in the mail the next day ($381). So in my case, it was a pretty fast response time. Funny, when it comes to getting my tax refund, it takes 6 to 8 weeks, but when I need to pay the state, it's instantaneous.

What does 75-300mm mean?

this is the number of millimeters a lens will make a sharp image at, usually from its back element. 50mm is usual on 35mm film cameras-i.e.as your eye sees a subject. Digital is different for each camera.

How can the image in a pinhole camera be made bigger?

a pinhole camera has a very small aperture for the light to pass through. Thus the sharp focus distance is very great too. You will get a bigger image if you move your paper or whatever the image lands on, further away from the pinhole.it may not be as bright, though

How do you get film for your Polaroid camera?

You need to specify what model Polaroid. The 100/660 pack is still made, but most of Polaroid's film line has been discontinued and is either unavailable or can only be purchased from boutique manufacturers or online auctions.

What is diptych photography?

A diptych is a photograph that uses two different or identical images side by side to form one single artistic statement. The two images can literally be in contact with each other, or separated by a border or frame. There are also diptyches in painting and drawing.

How many pictures can a 512mb memory card hold in a 6 megapix camera?

A 512 MB card can hold more than 1500 images depending on the quality of the images. Eg., If you have taken pics in macro mode or with "super fine" mode, it will occupy more space on the memory card and "fine mode" will take little less space and so on......so it entirely depends on the quality & size of the images present on the card.

Were cameras in color in 1969?

I do believe so.. I think it was the early 60's. My stepmother was born in 1957 and she said that she remembers having a color tv when she was young (less than 10). Hope this helps!

Is the film for a Polaroid camera expensive?

Yes, the 100-pack series instant film costs about $1.00 per sheet. They're sold retail in packages of 10 for $9.99; you may be able to find a better deal online.

Why paint when you can use a camera?

Photography and painting are not related as far as portraying visual images. You might also ask the question, "If there are movies why do plays still exist?" Painting is an artistic expression. There are paintings that are not based on reality, like the works of Picasso & Pollock. A camera can also be used as an artistic expression, too, if special care is taken to lighting and exposure.

What is the difference between a normal perspective lens a wide angle lens and a telephoto lens?

Briefly and without going into technical detail, a normal perspective lens produced what is seen in the viewfinder, and is normally 50MMM focal length, the wide - angle lens stretches the photograph and shows wider details in the viewfinder. These lenses are norally about 28MM, but variations can go down to 18MM The so called fish-eye lens) which produces distortion in tne photo. Finally, Telephoto lens bring objects closer and enlarge them. These lenses are produced in many focal lengths from 75 to 500MM and above, and are also avalaible in combinations such as 70to210MM and many more lengths. All these lenses have their usages but the selection is complicated by the lens aperture (f number) selected. Would suggest you go and obtain a copy od The Kodak Photography Encyclopedia for more detailed info!!......Dave

Is photography a trade?

Good photography is indeed a trade. It requires knowledge, skill and artistry to capture the perfect moment. It takes years to master. A photographer must first know how to compose color values, lighting, perspective and all that. Only then he can start taking pictures.

How do you put a camera on a tripod?

Look at the base plate of your camera. There should be a threaded socket there. Your tripod will be equipped with a corresponding screw in its head plate. The industry has standardized on a screw-and-socket arrangement (it's called 1/4" x 20 if you care). All tripods and all cameras should fit one another.

Many camera sockets, and some tripod screws, are now plastic or nylon so you need to be more than usually careful not to "cross thread" and "strip" the threads in either the socket or the screw. Underneath the tripod head the screw usually has some sort of knurled handle or grip for turning it, plus a wheel. You're not going to use the wheel yet.

Using the knurled grip, back the tripod screw down until it just shows above the head plate. Position the camera's socket over the screw and gently start the screw into the socket by turning the knurled handle. If you feel resistance, back it out and try again. Any serious resistance may mean the screw is cross threaded and if you continue you risk stripping.

When you have the screw well into the socket (about 1/4" will do it), the camera will now be attached to the tripod but you'll probably notice that it "flops." This is where the wheel on the screw under the tripod head comes in. By turning the wheel up the screw under the head you tighten the base plate of the camera against the head plate of the tripod until the camera and the tripod are a single unit. Just as you must be cautious about cross threading, you don't want to over tighten the camera to the head plate. Most of these things are relatively delicate and can be damaged or ruined by too much enthusiasm. You just don't want the camera to move independently of the tripod.

A couple of tips: you can defeat the purpose of a tripod if you touch the camera while tripping the shutter for a long exposure. Use a cable release or electronic release. Don't have a cable or the camera won't accept one? Try using the camera's self timer so you're not touching it when it trips.

If your camera lacks a threaded socket, you can still support it on the tripod head by hand. It's not as good as attaching it, but it's better than no support at all for a longish exposure. On that subject, you can also steady any camera for any exposure that might otherwise "smear" by bracing or resting it on a chair, a table, a car roof, a handy railing, or whatever you can find. Bracing your elbows on anything handy may help as well.

Tripods aren't always necessary: See the related questions on tripod use referenced below.

Is it possible to transfer pictures from a computer back to your digital camera?

It depends on a lot of factors as some may find out. Some Operating Systems such as Windows will not allow you to. And sometimes you have to deal with JFIF Jpeg's and Exif Jpeg's as the bottom post does. That person thoroughly explains the issues in my opinion. What you can try doing is inserting the memory card into a USB card reader or memory card slot if you have them. Or you can change your operating system to be able to move photos from the USB connected Camera. Yes. You should be able to find the camera listed under "My Computer" as either an extra drive, or by the name of the camera. It should be displayed as a "removable storage". Just pull it over to the drive and it will be on there. Some cameras can be 'uploaded' with their supplied usb/firewire cord. All memory chips are in effect external hard-drives when attached to a 'card-reader'. So! Whether you transfer files via the camera cord or via a separate 'card-reader' you must transfer a readable file only. That would be a 'jpeg'. Let's assume that you have taken pictures and downloaded them to your computer OR downloaded jpegs from the internet or via e-mail from a friend. If you wish to 'crop' or 'adjust' the colour and/or contrast in a computer software program, then upload to 'your' camera, again, remember to save as a jpeg file and NOT a tiff. or a gif. or photoshop file as the camera will not be able to display them on it's LCD screen. Do not believe for a moment that you can put across the idea that you took the pictures. Every camera 'codes' each picture with hidden 'data' that tells what camera, what setting and often the owners name. This data is available for deletion only and not modification and then only if you know how.

Many digital cameras have a built in codec specifically designed to read only a certain type of pictures. If your camera is like most digital cameras, the the process is very simple. Most likely your camera contains the JPEG Exif format. If the picture(s) you want to move to your camera is JIFF, then you must convert it to Exif. To know which version of JPEG it is(JIFF or Exif), simple open the image in notepad. You can do this by right-clicking on the image and then choose "Open With..." Then from the menu that may pop up, select notepad. You will see the data of the image, if it says Exif, then you can just go right ahead and move it to the camera without doing anything else which I will later talk about. If it does not say Exif, then you will need to convert it. To start off, you need to download Quick Exif Editor, just Google it up. Then run the program, click where it says open and choose your photo. Then look for a green + sign and a window will pop up saying "Read including Undefined Tags (Maybe dangerous) ." Many people who are not savvy with computers AND digital photography will have no idea what this means. All this means is that a part of the image will be edited which can result in a loss of image. Don't worry this will not damage your computer or anything like that, it will only damage the image SO I STRONGLY SUGGEST YOU MAKE A COPY OF THAT IMAGE. Next click on "Yes" to continue. Another Window will pop up saying "New Exif Tag." I strongly recommend you leave everything alone. The image only needs a small command line that's says it is an Exif JPEG so DON'T WRITE ANYTHING. JUST GO RIGHT AHEAD AND CLICK "ADD." Cameras only read pictures with an Exif tag, which is just a fancy name for the detail of the photo, such as date and other data. None of this data shows up on the image but rather it is hidden within the image. Usually an image data begins with what type of JPEG image. This makes it easy for a camera to read it. So that is why we need to add a simple piece of data that tells the camera that it is a JPEG. Your image is now an Exif Jpeg. Your image is now ready to be moved to your camera. To start this process, you will need a memory card slot in your computer. Typically memory cards allow files to be written on it and connecting your camera via USB to the computer will not allow it to. If you can move files to your camera via the USB, meaning that the camera is connected to the computer through a USB cable, then you are fine. If your computer does not have a memory card and your camera connected to the computer via USB will not allow files to be moved to the memory card, then you will need to use the memory card slot in your computer or you will need to buy a card reader that in which it connects to your computer via USB and and it contains a slot for your memory card. Make sure your memory card can fit onto the memory card slot, since there are different memory cards. You can check if your ccamera will allow you to move files to it when connected by the usb cord by connecting you camera to the usb port via the cable. Then go to my computer or computer and search for you device. DOuble click on it and then attempt to move a file onto it. If the file moves to the computer then you don't need to use the memory card slot or card reader to move the picture into it. If you cannot move the file then you will need either a memory card or memory card slot. If you have decided to use the memory card in your computer to move the files, please make sure the memory card is not locked. On the memory card, there should be a little switch which lets you know if it is locked. Plugin you memory card or the Camera via USB, and then search for where the pictures are located. Next, drag the picture that you want to move to your camera into the folder where all the pictures on the memory card or Camera are located. Next, look at all the names of the pictures in that photo. Some cameras use a common name with a number attached at the end. For example, Sony cybershot cameras use the name DSC00, with a three other digits. Look for a similarity in all the pictures. Then rename the photo to be part of the pattern of all the other images. This will ensure that your camera reads the image. YOu are now done. Turn on your camera, and view the image. If it says File error or you cannot find the image, then the process is a bit more complicated.

What is a aerial photograph?

Aerial photography is the act of taking photographs from an elevated position, often a non-ground based structure from which can be acquired by, but not limited to; an Airplane, Helicopter, Remote Controlled Aerial Vehicle, Rocket, Parachute, Hot Air Balloon and much more.

I am working at singaporeaerialphotography(dot)com as an Aerial photographer. I use drone for photographs.

What is A standard format used by digital cameras and scanners for transferring images?

TWAIN The word TWAIN is not an official acronym; however, it is widely known as "Technology Without An Interesting Name." The official website notes that "[this name] seems to haunt the standard."

Were there any photographs of bodies recovered from the explosion of the Space Shuttle Challenger?

It is possible NASA took some, or that some may have been required for autopsyor post-mortem purposes, however these are unlikely to find their way into the public domain for reasons of taste and privacy.

What is mergers in photography?

Mergers in photography are when a object in the background becomes part of your subject. like when there is a line going through someones head, or a banner looks like a hat on the person. another one is a border merger. this is when you cut off only part of someones arm. or just like 3 toes. this is a big no no in photography!

hope this helps! :))
