What is the function of film in a camera?

The film in a camera is what actually records the image focused on it by the lens. Film serves the same function as the sensor in your digital camera, but it does so differently. Film is coated with an emulsion made of gelatin in which are light sensitive salts of silver. When exposed to light, these silver halides as they are called become able to be developed chemically into an image which faithfully records the lights and darks of the original scene. The sensor in your digital camera does the same, except that it doesn't require chemical development to view the image.

What types of file formats do digital camera use to store images?

There are 3 formats that are most used. There are more but the most common are:

.png

.jpg (same as .jpeg)

.gif (for animated images)

Which camera should you buy?

It depends on how you like your shots and which way you prefer to develop them. Always go with an SLR. The name brand is your choice. Remember it is not the camera that makes it, it's the photographer, and your own perception on which you would like to capture your image. Whether you prefer a digital SLR or non-digital is your choice.

Ps., Check out The Art Institute of Santa Ana. It has a great program for digital photography!

How many pictures?

There realy is not a percentage that should be used, and not really a set amount. As a wedding photographer and the owner of my own company, I would expect no tip unless I went way out of my way for a family. Generally if the photographer is working for someone else (another photographer, studio, etc.), then I would tip $50 to $100, maybe as much as $200 if you receive really good service. I would not tip if the photographer is working for himself. If he/she brings an assistant, then tip the assistant.

Some people go as far as waiting for the proofs before tipping. This is completely up to you as the client.

Are there colleges for photography?

What are some advantages of a HD video camera vs. a standard video camera?

HD video is a television standard that contains approximately 5 times the amount of data as standard definition television signals.

HD is formatted as either 1080 line or 720 line. Both line counts are HD. 1080 line signals can be interlaced or progressive scan. (Interlaced requires two fields, or passes of the display, to fully update the image, progressive fully updates on every field)

Frame rates can be 23.98, 24, 25, 29.97, 50 or 59.94 frames per second depending on the region or the type of content.

HD signals in the studio are always digital whereas SD signals can still be processed as analog.

Domestic equipment carries HD only on HDMI connectors. New equipment does not support HD on analog interfaces to reduce unauthorized copying of material.

HD is always 16 : 9 aspect ratio (wide screen). In comparison, SD can be either 4 : 3 or 16 : 9 although wide screen SD is largely confined to European markets.

Why was the digital camera created?

Originally the camera was made to capture a moment in time quickly and exactly. Paintings often reflected the opinion of the painter in their art, however, photos show exactly what was happening. Photos can be biased but nonetheless they are real. Photography started becoming pretty well known around the civil war and that's where the first "imbedded" journalists began.

The first use of a lens that projected light onto a wall was the camera obscura (dark chamber)- this is where the name 'camera' comes from. The concept of 'light paintings' was created long before a method of permanently recording the image. The merging of physics and chemistry was required to allow this and resulted in the discovery of silver elements that turned black when exposed to light.

The main reason for its invention was to help artists in drawing difficult subjects. However, since the physics behind the camera were discovered by many different people across the world, they were subsequently used for different reasons.

Can you transfer pictures from a computer to a digital camera?

Make a file backup folder on your computer and copy all those photos to it and call it a by new name.

Now delete the bad or poor pixs from the orignal photo file . Select the pictues remaining one by one or other and send them to your camera which is listed as a drive. Or select each pix -copy them - and paste them to the camera drive storage. Practice this first- after making a file you copied all into.

Is there a machine to convert 35mm negatives to digital photos?

Yes. There are scanners designed specifically for this purpose, sometimes called negative scanners (which is mildly inaccurate). They are typically much more expensive than plain old flatbed scanners. You might want to look at the ones made by Nikon, or if you don't mind something used and older, try to find a Minolta film scanner.

Large commercial outfits will use enormous and frighteningly expensive drum scanners for the same purpose. Depending on how many you're scanning, you may well find it cheaper to get in contact with a company that deals with this sort of thing.

Which brands make digital cameras?

The answer depends on what's important to you. Image quality? Ease of use? Size? Versatility? Telephoto range? Macro ability? Low light performance? Learning about photography? Hi-def Video capture? Cost?

If you're looking to get into photography as a serious hobby, the best all-around point and shoot in terms of features, image quality, and growth potential is (in my professional opinion) the Canon G10. I know quite a few other professional photographers who use the G10 (or it's predecessor the G9) as their "go everywhere" camera for when they don't want or need a full SLR rig. The Nikon P6000 is it's main competitor.

The disadvantage of either of these are price and size -- they're bigger and more expensive than most consumer point & shoot models.

What does macro mean in photography?

Macro photography means taking real close up photographs of your subject like flowers or even baby's toes to capture a lot of detail in your photos.

What did the first camera look like?

The early cameras were very boxy things with the very first often being similar in size to a coffin.

the first camera was called a camera obscura. it was invented in the middle ages to aid artists in doing realistic paintings. it was a dark room with a pinhole or lens in one wall and the artist stood inside it with the image projecting on his canvas as he painted.

How do speed cameras work?

There are several different designs and systems depending on the manufacturer of the device, but a basic type operates by timer. Once the light turns red it activates the camera mechanism and anything that passes through the camera's field of view triggers the camera to take a picture. Other more sophislticated types work on the same principle as radar. When a vehicle crosses its field of view after the light turns red, it triggers the camera.

What part of the human eye corresponds to the lens of the camera?

The iris.

- - - - -

No. It's the eyelid. The shutter's function is to completely stop light from reaching the film (or the sensor, if you have a digital camera with a mechanical shutter). The iris in your eye cannot do this--only the eyelid can.

What is the difference between a video camera and a digital still camera?

Conventional/traditional photography is the use of film to capture images in a camera. The film then must be developed, resulting in negatives (negative images) of the images. These negatives are then enlarged using special equipment and paper and then printed and developed chemicals. Digital cameras capture images using sensors on a memory card, which are then transferred to a computer for printing on specialized printers. The benefits of traditional darkroom photography is the amazing quality of the photographs. Only in recent years has digital photography even began to compare to the quality of traditional film, but it is increasing in both quality and popularity. In the near future it is projected to be equal to and even surpass traditional photography. The benefits of digital photography are the ease of use and convenience. Images can be viewed and deleted instantly, instead of shooting through multiple rolls without knowing if you have a successful image.
