What part of your eye is like the diaphragm of a camera?
It is identical in action to the iris in your eye, it widens and narrows to allow only the required amount of light through the aperture hole/pupil
it is easier to cut and past photographs and compare :)
What is the difference between maps and aerial photographs?
Aerial photographs are prospective projection while maps are orthographic projection
Can you use a memory card for your camera to put it on your computer?
Yes. That's the beauty of memory cards. Take photos with your camera and directly transfer them to your computer by plugging the memory card into the computer.
How has the discipline of photography impacted digital graphic design?
I'm not real fond of this question, so let's rephrase it into a similar one that's better: How has the availability of affordable, high-quality digitized imagery impacted digital graphic design? Executive summary: Affordable digitized photos have made it possible for more publishers to use more photos and more color than ever before, which enables them to attract more readers. First, let me tell you about the really old days--back in the 1960s. If you wanted to print a photo in your magazine (forget "newsletters"--those never had any pictures) and you just wanted black & white, you took a picture of it through a "halftone screen" onto Photo Mechanical Transfer paper. The screen broke the photo into dots of various sizes, which made it printable on press. You pasted the PMT onto an artboard and shot the board on the same camera. Then you stripped the negative into a flat and made a plate from it. If you wanted color photos, you shot the photo four times with different screens and different filters in front of the lens, then stripped those negatives into your layout flats. Color was something you only did every once in a while--the cover and maybe two or three pictures inside. And newspapers NEVER ran color photos, except in the special "Rotogravure section" on Sunday. (Ask me later what rotogravure was.) Forward to the late 1970s. There were two ways to do a color photo. The first was to use a drum scanner--a very large machine--to create the separations. The other was to use an image editing workstation like a Scitex or a Hell. Either way you're looking at somewhere between half a million and a million and a half to buy the equipment, and you need a lot of training to use it. It was far easier to make separations, and the seps were better, but it still cost too much to throw a ton of color photos on a page. Now? It's so simple to put tons of photos on a page, everyone does it. The pages look a lot better than they did in the old times. They're prettier. Now here's the flipside: very few people, outside New York and Los Angeles, actually care about what they're putting out, as far as quality goes. Everyone thinks you can fix anything in Photoshop, so you get pictures that are blatantly awful. Now, we get pictures of the company's CEO in a wrinkled suit with a huge shiny spot on his forehead. Thirty years ago, he wore a freshly-pressed suit to the photo shoot and his secretary put a little makeup on him before he went in front of the camera. The difference was night and day. Do I want to go back to the old days? In a way, yes. If I could get the nice professional-looking photos we used to see, but not have to strip flats together by hand, I'd be a happy camper.
Why is iodine used in photography?
Almost any heavy metal can be used as a toner in photography, ... that being said, at one point or another iridium was used as a toner, producing a yellow image (much lighter than sepia) But since iridium is radioactive (only mildly- you would have to eat it or cover your skin with it to absorb more radiation than a day in the sun) there is no reason to use it except for the learning experience
How do you reset a augen mp4 player touch screen with camera?

Why are there no stars showing in photographs taken on the moon?
Why Space Appears Black
I think you're asking why you don't see the stars.
Any imaging system only has a limited range ("dynamic range") over which it can usably detect what it's looking at. In other words, it has to have a maximum bright, beyond which everything is just imaged as bright white, and a minimum dark, with anything darker than that indistinguishable from completely black. Eyes, film cameras, and digital cameras are all subject to this limitation.
In order to image the things of interest (the Space Shuttle, the Moon, the Earth) the dynamic range of the imaging device has to be set to be appropriate for the target. Stars, even though they put out some light, are still too dark to be distinguished from the black background, so they aren't visible, nor can they be photographed while the camera is looking at something bright.
Also, space has no atmosphere, so the astronauts are working in essentially an empty vacuum. There is no material to refract or reflect light, except the Moon, the earth, and the spacecraft and astronauts. So that is what you see.

Here is more input:
- In 1839 by Jon Bradford Eagle
- Actually, the word "Camera" comes from the Arabic word "Kamra" which means "Dark room". The Camera was invented by a Muslim Astronomer/Physicist/Mathematician Alhazen. Europeans have taken a lot of inventions by Muslim scientists and called them their own. the camera is one of many.
- The above 'Muslim-Centric' poster needs to check their facts. Alhazen did NOT invent the actual camera, he was merely a mathmetician and a comsmetician that copied scientific texts to enhance his income when he lived in Cairo. He took other discoveries and copied them for his own monetary gains. He did do an essay on Optics but his essay had nothing to do with the physical invention of the modern Camera. The term 'Camera' is derived from the latin words 'Camera Obscura'. The word you mention (which you did not spell correctly) 'Kamara' means 'Vaulted Chamber', not 'Dark Room' as you so incorrectly stated. Please check your facts before you post your incorrect and obviously one sided views. As for Europeans taking a lot from Muslims, you need to understand that many discoveries in this world were taught and handed down to others and expanded upon. It is that idea of SHARING that makes this modern world a fun place to live. Please do not disparage the rest of the world with your racist isolationist beliefs. Something that benefits all mankind should be shared, not greedily kept 'yours'.
- To the best of my knowledge the negative / positive photographic process was first pioneered in England by an inventor called William Fox Talbot (1800 - 1877) in a abbey called Lacock.
- Did you also know that to this day filmmakers can't resolve the problem of car or wagon wheels going backwards in a movie? Next time you watch a movie, take a close look at the car's wheels.
- This backwards wheel effect might be due to the limits of the film (modern films are 24 frames a second, earlier films were less) producing this effect on your eye. I believe the human eye can process 28 frames per second but this discrepancy on film might be due to the slower rate. It also does this on propellers of airplanes in films.
The first type of camera/imaging device is called the camera obscura. This was an optical device used in drawing, and one of the ancestral threads leading to the invention of photography.
The principles of the camera obscura have been known since antiquity. Its potential as a drawing aid may have been familiar to artists by as early as the 15th century; Leonardo da Vinci once described the camera obscura. See links below for more information.
The first camera that was small and portable enough to be practical for photography was built by Johann Zahn in 1685, though it would be almost 150 years before technology caught up to the point where this was possible. Early photographic cameras were essentially similar to Zahn's model, though usually with the addition of sliding boxes for focusing. Before each exposure a sensitized plate would be inserted in front of the viewing screen to record the image. Jacques Daguerre's popular daguerreotype process utilized copper plates, while the calotype process invented by William Talbot recorded images on paper.
Modern times
However, one of the first and most easily recognized types, popular and easy- to-use for consumer too, was the single lens reflex (SLR) camera. This type was and is most commonly used from around 1959 to present. One of the most successful, easy-to-use and professional models of this type was the Nikon F.
AnswerDaguerre announced the latest perfection of the Daguerreotype, after years of experimentation, in 1839, with the French Academy of Sciences announcing the process on January 9 of that year. Daguerre's patent was acquired by the French Government, and, on August 19, 1839, the French Government announced the invention was a gift "Free to the World." AnswerActually the first 'camera' was designed before Columbus. It was by simple deduction that an artist noticed a faint image on the opposing wall of a small building where a small hole was in the lighted side of the building. He worked on a lens that could be placed in a similar hole of another building and he noticed that the image on the opposite wall was rather clear, color and all, although upside down. He then proceeded to use oil paints that were in use to paint portraits at the time. He simply mixed the oils to match the colors and painted directly onto the image he was looking at. Today's cameras do the same thing minus the oil paint. Film cameras have replaced the oils with both silver halide salts and dyes. Digital cameras simply use super miniature diodes that are photo etched onto silicone slices (chips)and translates different ranges of the color spectrum into binary or machine language digital code. AnswerGeorge Eastman (July 12, 1854 ? March 14, 1932) founded the Eastman Kodak Co. and invented roll film, which brought photography to the common man. The roll film was also the basis for the invention of the motion picture film, used by early filmmakers Thomas Edison, the Lumi Brothers and Georges MThe first permanent photograph was made in 1826 by Joseph Nicore Nie using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. However, while this was the birth of photography, the camera itself can be traced back much further. Before the invention of photography, there was no way to preserve the images produced by these cameras apart from manually tracing them.
The first camera that was small and portable enough to be practical for photography was built by Johann Zahn in 1685, though it would be almost 150 years before technology caught up to the point where this was possible. Early photographic cameras were essentially similar to Zahn's model, though usually with the addition of sliding boxes for focusing. Before each exposure a sensitized plate would be inserted in front of the viewing screen to record the image. Jacques Daguerre's popular daguerreotype process utilized copper plates, while the calotype process invented by William Fox Talbot recorded images on paper.
The development of the collodion wet plate process by Frederick Scott Archer in 1850 cut exposure times dramatically, but required photographers to prepare and develop their glass plates on the spot, usually in a mobile darkroom. Despite their complexity, the wet-plate ambrotype and tintype processes were in widespread use in the latter half of the 19th century. Wet plate cameras were little different from previous designs, though there were some models (such as the sophisticated Dubroni of 1864) where the sensitizing and developing of the plates could be carried out inside the camera itself rather than in a separate darkroom. Other cameras were fitted with multiple lenses for making cartes de visite. It was during the wet plate era that the use of bellows for focusing became widespread.
AnswerGeorge Eastman invented the camera in 1888.Ibn Haytham, a Muslim scientist was known the Father of Optics, He invented the first telescope and optic's concept. why so many claims without proves ? almost All modern sciences are comes from Muslim scientists.
The movie "Lemonade Mouth" was filmed in Albuquerque, New Mexico... They also used 3 different High school's for the movie...
Albuquerque High School for the soccer field and parking lot scene,
Cleveland High School in Rio Rancho for the auditorium scene at the end,
Atrisco Heritage Academy High School for all the other scene's
They filmed all the Historic part's of Albuquerque:
Old Town KiMo Theatr located in Downtown Albuquerque,
The old railroad station also located Downtown where they had the mudslide crush consert in the beggining with all the old stained glass windows and the santa Ana star Center (home of the Albuquerque Thunderbirds) im Rio Rancho for the big concerts.
so yeah there's your answer, hoped it helped!
What is the best photography program?
Depending on what you want to do with the photos. For Image manipulation such as resizing, color correcting and special effects the best program is Adobe Photoshop. For Image editing and organizing use Adobe Lightroom or Apple's Aperture .
What is the best digital camera for fast shutter speed?
To the best of my knowledge, it is the Olympus E3 at 1/8000 second as of 2008. However, an important measure of digital camera speed is also fps (frames per second) as the camera must meter and check focus and other settings before taking the shot. At present DSLRs can't be beat in this regard. Compact digitals usually suffer from shutter lag. Casio claims the fastest fps at 60 fps, 6.0MP, jpeg as of Aug. 2007. You should denote from this that the fps numbers alone mean nothing unless everyone is using the same yardstick. When have the manufacturers ever done that?
19th century photography pioneer?
Louis Jacques Daguerre, Fox Talbot, Ansel Adams, Margaret Cameron. It's hard to choose, they all came up at the same time, since photography was invented in that century.
When was the first camera introduced to the public?
The use of a lens in the opening of a wall or closed window shutter of a darkened room to project images used as a drawing aid has been traced back to circa 1550. Since the late 17th century portable camera obscura devices in tents and boxes were used as a drawing aid.
How and who was the first camera discovered?
The term camera comes from the Latin "camera obscura" which means dark chamber and was a small box with a mirror inside that would project an image onto a piece of glass. The first camera obscura was probably built by a man called Alhazen in the 11th century. Later, during the Renaissance, many artists like Leonardo Da Vinci used a camera obscura to trace a scene that they would later paint. So, the original camera was used for painting on canvas, not for taking pictures as we normally do now. And even now, the camera obscura is not even a traditional camera, but a microchip in a digital camera.
What controls sharpness and depth of field in a picture?
The longer the exposure the more light is let into the camera, as a result the picture will be brighter/lighter/whiter. The shorter the exposure, the less light let in, and the darker the image will be.
Answer:Aperture can affect the quality of a photographic image in at least four ways.First, and most well known, as the aperture (the lens opening -- the hole through which the picture enters the camera) gets larger it lets in more light and you can take a picture in darker locations, or you can take pictures at higher shutter speeds thus freezing movement better.
The next most commonly known effect is that the wider the aperture the shallower the depth of field. That is, the fewer things in front of or behind the subject of the picture are in focus. As the aperture gets smaller things further away from the subject in both directions are clear.
Another way aperture can affect the image is that your lens will be sharpest at some aperture. Often somewhere around F5.6 to F8 your lens will make the sharpest (clearest) images. This is called "the sweet spot."
Finally, for technical reasons, at very small apertures (usually F16, f22 or smaller) an optical phenomenon caller diffraction causes the image to become become less sharp. You can think of it that when light must squeeze through a tiny hole the light rays interfere with each other.
What is the importance of photography in advertising?
Photographs are not space fillers in a newspaper as many may think. Photographs are used to make ideas explained in writing more visible and fathomable to the readers.
They are also used as the selling point of any publication in that case meant for such.
A well taken photo is worthy a thousand words, so editors will always have space for photos in their publications.
My camera accidentally erased all my pictures can I ever get them back?
You could try RePicvid Free Photo Recovery to restore deleted photos from Camera. Just remove the SD card and connect it to computer, then run the software and follow the user guide. It is reliable and easy.

Does an iphone 4g have a front and back camera?
If you mean a camera that faces you while you look at the screen the answer is no.
How do you connect cctv camera to a cable television?
Most PC monitors use VGA (DVI is also popular - you can easily convert VGA to DVI with a simple adapter).
Most CCTV camera systems are BNC - all you need to connect your CCTV camera to a regular PC monitor is a BNC to VGA adapter. They can be had for anywhere between ~$40-70.
What does eye level camera angle mean?
Holding the camera at the level of the adult human eye. It's the most common angle used. Try "toddler level" once in a while to remind you of what things used to look like (in my case) decades ago! Try almost ground level sometimes (especially for uncluttered landscapes).
How much is a professional camera?
It Really Does Depend What Your Looking For. If Your New To Photography Than I Would Go With A Kodak z981. (The Camera I Use) It Takes Amazing Pictures! But The Video On The Camera Is... Okay. But If You Want To Take Good Photos I Recommend You Use It Outdoors. Indoor Lighting Doesn't Take Good Quality Photos At All With This Camera. This Camera Is About $300. If Your Not A Beginner And Are Looking For A Truly Professional One The Are Near $1000. Hope This Helps (:
