What is Movement within the picture plane in photography?
According to an online dictionary it means the act of assuming of a certain position. Photography is a very creative and popular 'art', therefore there is a lot to know about it - you can check for several books about photography on the internet is you wish.
How bright are red light cameras?
Just as a quick explanation - As a vehicle approaches an intersection the vehicle is detected with a series of in-ground loop detectors. Based on time distance calculations the speed of the vehicle is determined. The computer takes inti account the speed of a vehicle and the likelihood that the vehicle will violate the red light based on the traffic signal phasing. If the computer determines that a violation is likely then the cameras will be activated.
Another View: -OR- it operates as simply as the camera being turned on whenever the red light is lit. Then, it takes a picture of any vehicle crossing the intersection AFTER the red light has actually illumminated.
Where does the word photography come from?
Photography is a method for producing lasting images by means of a chemical reaction that occurs when light hits a specially prepared surface. It was invented during the first decades of the 19th century as a direct consequence of advances in chemistry and optics (the science of the behavior of light). The word Photography comes from two Greek words that mean "writing with light".
The best cameras used for photography?
There is no single "best" camera. First, please see the answers to the questions, "Which is the best professional camera," and, "Do all cameras produce the same image quality?" Those related questions are both referenced below so you can just click on them. They will answer a lot of questions without repeating them here. If you're in the market for a camera, proceed with caution as cost does not necessarily equal quality.
Everyone thinks they want the "best" camera, but best for you and best for me are two different things. If you initially buy "too much" camera and can't work it, it's not the best - for you. Any camera that works at all is as capable of taking wonderful pictures as awful ones (and beauty is always in the eye of the beholder). Some of the great names such as Nikon, Canon and Pentax can be blown away by some of the lesser known (see Consumer Reports), but everything is relative. Do lots of homework. Lens quality is always huge, but if you're thinking digital be careful about falling for the Megapixel Myth. More can be less. As you cram more megapixels into the same size sensor, you may degrade sharpness. I think 10 mpx in a small point-and-shoot is about the maximum, and even that may not be as sharp as, say, a 6 mpx (but you can get bigger enlargements from a 10 mp).
What is the salary of a director of photography in first year?
I earn +300k per year in Michigan. If you're out in Hollywood or Chicago; probably closer to +500k-600k
There is probably a union scale for the DP; depending on the project's budget, producer, and so forth.
What is the best way to photograph underwater through a glass?
The answer, of course, depends on which camera you are using, what objects you'll photograph, and the desired style of your photo.
Style:
Let's start with style of photo first. If you want a wider angle, curved view, fisheye look, you'll want a fisheye lens. If not, you'll select a rectilinear lens. Some fisheye lenses can capture 180 degree field of view and distort the image. If you're taking a picture of a single shark, for example, a fisheye lens may not produce the most pleasing image.
Objects:
If shooting large aquatic animals, you'll typically want a rectilinear zoom lens. Because it's difficult to obtain quality photographs from a distance underwater, the focal length will still be fairly short, usually less than 24mm. For smaller objects, you'll typically want shorter focal lengths.
Camera:
Canon and Nikon have excellent lens choices, but third party lens manufacturers also make great lenses, but are typically less expense. Here's a good lens list for Nikon and Canon:
For Nikon:
Fisheye:
Nikon 10.5mm (cropped sensor)
Tokina 10-17mm (cropped sensor)
Rectilinear:
Nikon 10-24mm (cropped sensor)
Nikon 12-24mm (cropped sensor)
Sigma 8-16mm (cropped sensor)
Tokina 12-24mm (cropped sensor)
For Canon:
Fisheye:
Canon 15mm
Sigma 15mm
Tokina 10-17mm (cropped sensor)
Rectilinear:
Canon 10-22mm (cropped sensor)
Sigma 10-20mm
Sigma 8-16mm (cropped sensor)
Tokina 12-24mm (cropped sensor)
How do you download photos from camera to my PC?
This really depends on what kind of camera that you have. Some you need a USB cord that plugs into your USB drive, and it will assist you when you need to upload them. These instructions, again, depend on your camera and PC model. If you have a camera that uses a data chip, it would plug into the K drive of your computer, which is usually below the USB drive (it is on mine.) It would look like a thin, long plug that is on the side of your computer that would look like the side that you plug the chip into. Again, this depends on your PC, camera, and your method of uploading the pictures.
Use shutter priority mode (S mode on dial) or manual mode (M on dial) and then select the speed you want by using the dials.
What are the advantages of radio compared with other media?
I think I can speak from personal experience here: here at Eaglehawk we have just had bushfires that destroyed 50+ houses. Among other things, we were all explicitly told to listen to the radio, preferably portable (ie battery-powered) for news and updates about the fires. TV:- We found that TV was next to useless because we didn't want to see a pretty talking head showing what had happened on the other side of the State: we wanted to know what was happening right now right where we were and TV couldn't do that. - there was inteference and if anything happened to the antenna it was useless.
Internet:- It was almost the same with the Internet: it was even worse than the TV in giving immediate information because it couldn't. The fastest was a "just-in" News Flash that was 6 minutes old: it sounds good, but a lot can happen in 1 minute, let alone 6 of them. Disadvantages of the Internet:
- you had to know exactly what site to go to get what you wanted: - you couldn't do that under stress ; - you just didn't have the time; - you couldn't just turn it on and get what you wanted immediately. -it was visual, just like the TV: you had to actually watch it.
- if anything happened to the phone line/wi-fi it was also useless.
An advantage of the Internet was you could go to 'Country Fire Authority' site (www.cfa.com.au) and see where the different fires in the State were and what stage they were at.
Radio:-
By contrast, a portable radio was by far and away the best option.
-Power outages meant anything on Mains power was useless, but it didn't affect a battery-powered radio.
-Information was immediately available and always up-to-date: in an emergency you're talking about a 10-second delay
(eg "People in ........ : look out - we've just been told that .....")
- The radio station gave localized information about what was just happening right then in the next street or other side of the hill.
- It was also exact and precisely-targeted to an audience that was hanging on its every word.
- You could have it on in the background and listen to it with half-an-ear while doing something else.
-It was small small and easily-manageable.
- it was portable: you could take it where you wanted when you wanted.
- You didn't have to worry about losing the TV antenna or internet connection or links.
- on the FM band there was no static or interference.
What is the best way to photograph the moon with a digital camera?
You will need a tripod as long exposure is involved with photographing the moon. You will also need a fairly long lens - the moon, particularly on the horizon looks larger than it actually is, the camera lens is not fooled by this and the part of the image taken up by the moon will be quite small even with a longish lens (around 200mm say). Assuming you've armed yourself with a tripod and a telephoto lens, then the other problem is exposure. At night, the moon is, effectively a bright blob in a large area of black. The camera exposure system assumes you are photographing an average gray scene (by average, I mean 18% gray). The result is that if you use the camera exposure system set to automatic, the moon will be very over exposed - perhaps by 3 or 4 stops. There are a number of ways around this: # With an ISO setting of 100, the correct exposure is around 1/90 at F16. Set your camera to manual exposure and use that setting. If the ISO doesn't go down that low then you will need to adjust the aperture or exposure time appropriately. # Use a spot exposure facility (if your camera has that) and expose on just the moon. # Use exposure compensation and take the exposure down by 3 stops. Between shots, look at the preview screen on the back of the camera and see what the image looks like - making adjustments as appropriate. Although it doesn't look like it, the moon is moving quite quickly across the sky and you'll need to adjust the tripod regularly to keep the image in the viewfinder.
What angle in photography is shot from the ground?
There is no single answer to this question. It depends on the shot being taken, the lens being used and the artistic or functional purpose of the picture. In general, take the picture from two angles if you have time. Look for an interesting angle, squat down and take the picture at a view other than your eye level. I love to sit down on the floor and take pictures of children at their eye level or stand on a chair in a crowded room, just to get 18 inches difference in my angle, it shows how full the room is. Examples: Portraits are usually taken where the lens is at eye-level for a visually comfortable picture. If the purpose was the make a person look smaller or perhaps childlike the camera might be raised to look slightly down on the subject. In the same way, lowering a camera will make subjects loom large in the frame and create an effect of power or dominance (this may not register consciously) Wide-angle nature vista photos are often taken with the camera lens 8-12 inches off the ground, with an interesting foreground element. This gives the picture great depth, with a huge sky and a tiny flower in the same exposure. When photographing buildings I like to move to one corner of the building and take a picture of the front of the building, this gives the picture depth and creates interesting graphic vectors in the frame. If you need a shot of the front of a building getting the camera lens about 1/2 to 2/3 of the way from the ground to the height of the top of the building will make it look more inviting. Staying close and shooting up will make it loom large in the frame, like with portraits. In situations where this is not possible specially designed lenses can compensate for the effect, or digital software can be used after the picture is taken.
A megapixel is one million pixels. A pixel is a picture element. Like graphics displayed on a television or computer monitor, digital photos are made from millions of tiny colored dots, or pixels. The more pixels used to produce a photo, the less "grainy" it will appear and the better any enlargements made from it will be.
A 6-megapixel camera can produce standard 4 x 6 photos at a remarkable 500 pixels per inch and 8 x 10 photos at 273 ppi.
A megapixel (MP) is 1 million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.
Canon ZR 930 is what I have its a fantastic camera great quality and you could probably find it somewhere for under 200.
How do you upload videos from a digital camera to your mac to facebook?
you copy this link in the address bar, go to facebook, paste the link
I know loads of people with this question you have to go on the application in the search bar type in video, it should appear and then click on it and add the application then go onto profile and press the + button the video should be on there
How did the public react to the invention of photography?
The first digital camera to be widely marketed to consumers was the Apple QuickTake 100. It held 8 images at resolution 640 x 480, was fixed-focus, connected only to a Mac (and it didn't have media cards--you had to connect the camera to a computer to get the pictures off), and cost $750. The reaction was very simple: "You want $750 for THAT? No freakin' way!"
On the professional side, we had Better Light backs for view cameras. They cost $35,000 and had to be tethered to a computer in use. They were also "scanning" backs. Imagine taking a small flatbed scanner, that has to make three scans--one each for red, green and blue parts of the image--and putting it on your bellows camera in place of a film holder. Better Light is still in business and still makes these backs, but they're not as expensive now and the new ones scan all three channels in one pass.
How photographs are developed?
Film is developed in a light tight bag or room and developed with three chemicals and water: developer, water, fix, hypo, and wash, with times dependent on the type of film. When your negatives are dry you can take a section of them and slide them into the film carrier and place it in the enlarger. I prefer to turn on the light all the way to the furthest brightness and then use the handles or switches on the side to adjust the focus. There is also a wheel on the side of the enlarger to adjust the size. After determining the focus, turn down the light two stops and take a small piece of photo paper and test the times with intervals of 3 seconds. Take the piece of paper and leave it in the developer with agitation for one minute and decide which exposure time looks best. Proceed with a larger sheet of paper and finish the developing with water, fix, and a water bath, air dry or blow dry to finish. And you have a photo!
howstuffworks.com also has an article about instant cameras and how instant photos like Polaroid photos are developed.
Further to the above which only covers monochrome colour photography can involve the use of seven different chemicals. Everything has to be processed in complete darkness. The film is processed as per the mono system except you work at higher temperatures using colour chemistry. You can use the same processing tank as in black and white. However you need to keep the tank in hot water at the temperature required. Printing has to be done in complete darkness which is why most of us either have an expensive processor or leave it to a colour lab. You can use a dish system but it is not very consistent. To be honest mono can be fun but colour can be a nightmare so I suggest you take your colour to a lab.Developing ColorThere are four types of color processes: color print film, color slide film, prints from negatives and prints from slides. The critical thing in developing color is temperature--it runs at 38 degrees C, plus or minus 1/4 degree C. That is a REAL tight standard, but it's attainable. Some people use styrofoam coolers and aquarium heaters, others fill the bathtub with 102-degree water and the real rich people used to buy special desktop color processing machines. These were made in Germany by a company called Jobo and they've been discontinued since 2006, but you can occasionally find used ones.
Color print is REAL easy--3 minutes 15 seconds in developer, wash the film, 6 minutes 30 seconds in bleach (which converts metallic silver into fixer-soluble silver halide--color images are made from dyes, there's no silver in the final image), wash the film, 6 minutes 30 seconds in fixer, wash for 10 minutes, soak in stabilizer for a minute, squeegee and dry. In the modern era the best way to print this stuff is to take it to Walmart and run it through their self-service printing kiosk.
Color slides require either three or seven baths, and the three-bath systems are awful. The three-bath system is first developer, color developer and bleach/fix. All film produces negatives no matter what kind it is. If you want a positive image, you develop the negative in a bath that won't create any dye (it's a black and white developer; I once tried developing black and white film in this and it turns out to work pretty well, but if you're looking for lots of contrast this is the stuff to use.) then chemically fog the remaining silver, develop it in a dye-generating developer, then bleach, fix and stabilizer. The seven-bath system, which is sometimes called a "six-bath" system, is first developer, reversal bath, color developer, prebleach (used to be called "conditioner"), bleach, fix and stabilizer. The three-bath process puts the reversal agent in the color developer, combines bleach and fix (which MOST companies do these days--Kodak's official process was designed decades ago when the bleach wasn't the same product it is now) and eliminates the prebleach. Putting the reversal agent in the color developer makes the life of the CD real short, so if you get one of these kits use it and dump it the same day.
As for printing, if you're not making 20x24s or something you're far better off to go to a PhotoMaker kiosk and do it there.
Photo DevelopmentGo to HowStuffWorks.com and search for 'film' or 'photography'. One of the first few results that turns up will be an article called "How Photographic Film Works."
This article discusses developing both color and black & white film.
Which camera is best for architecture?
A tilt-shift lens for 35mm photography. I've never seen a real one (just pictures in books) and don't know if they are available in medium format systems. However, the best tool for the job, hands down, is a large format camera that has tilt, swing and shift.
Who invented the Apple Quicktake camera?
The Apple Quicktake camera was invented by Steven J Sasson and others with the Eastman Kodak company and was introduced in 1994 in association with Apple Computer. The camera was the first consumer digital camera.
Digital camera Where is it used?
Nearly most people use cameras, they have become part of everyday life, with one coming on modern day phones. Depending on the type of camera it depends who will use it; a normal person would use a phone camera or a basic digital camera, but professional photographers would use SLR cameras to create a better picture quality
How much do professional photographs sell for?
Fine Art: The answer depends on who took the photograph, how collectible that photographer's work is, the quality or appeal of the image, where the image is purchased, the size of the reproduction, the number reproduced, whether the print is an original, one-off, limited edition or open edition, whether it's signed. You could pay less than $100 or tens of thousands of dollars, or more.
For other types of professional photography (portraits, sports, commercial, stock, etc.), there are too many variables to answer the question succinctly. You can find entire books devoted to the topic (see Related Links).
DSLR = Digital Single Lens Reflex
It's a digital camera made to look like a 35mm SLR. Usually the lens is interchangeable, but not always.

When was the Victorian camera invented?
3003
The first successful picture was produced in June/July 1827 by Niepce, using material that hardened on exposure to light. This picture required an exposure of eight hours.
How many digital cameras are there?
Alot. I mean, there is no specific answer, although 3/4s is a good estimate.
How much would it cost to start a clothing business?
This will depend on many factors, of course. Among the big questions: is this a new clothing line or a business that manufactures clothing? Is it both? There is a reality TV show that offers $100,000 to its winner to start a new clothing line. This amount is completely arbitrary. You may be able to get started with little or no investment. You should be able to develop a prototype of your clothing on your own, or with the help of a seamstress or tailor. Then you can take this prototype to local stores to sell them on it. When you have buyers, you can have the clothing made.
