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.

How do you get the camera on Toy Story 3 PS3?
you need to take control of Metal Gear Mk. II during all of the the mission briefings. If you explore around the Nomad with the Mk.II you will find extra batteries(for all your electronics: solid eye, Ipod etc.) extra ammuntion, and the camera throughout the Mission briefings.
How do police know who was driving your car when caught speeding by a police camera van?
Traffic cameras are very high resolution. Many will be set up to take a photo of the oncoming vehicle, AND one of the vehicle as it moves away, from the front and rear. This give law enforcement a vivid picture of the front of the vehilce with the face of the driver, and the back of the vehicle with the tag.
Will there be a camera for the ipod touch fourth generation?
The current generation iPod Touch does not yet have a camera, but all current generation iPhones have a camera.
There have been discussions about adding a camera feature to the iPod touch, but no improvements have been made yet. There has been a video option for the new iPhone 3GS, though.
Can i use a webcam like a security camera?
The answer is YES! There is many software to use with a webcam as a security camera. Altough it is quite simple to install, it's not really discrete. Depends on what you want to do with the cam. Remember to check for the quality you require. Some webcams are not that efficient on getting clear images. There is some good softwares or freewares to try, but generally you have to buy them after a certain time for under 100$. Try inserting "Webcam monitoring" in Google, and you will have a good overview of the softwares available.
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).
Why are images upside-down in a pinhole camera?
You can figure out why an image in a pinhole camera is upside down if you think about how the light travels to get to the image.
Light from an object higher (or the top of the object) than the camera travels in a straight line down to the camera. It goes through the pinhole and continues heading down until it hits the back of the camera. This means that the image of something higher than the camera is now low in the image. The opposite is true for light from an object lower than the camera (or the bottom of the object): it travels to a point higher in the image.
Still does answer my question, how did the image get upside down? answer was no concusive.
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.
I think the PSP camera is only sold in Japan and the US. I was told this by someone at a GameStop.
GAME in the UK sometimes has them.
How long do batteries last in wireless security cameras?
Depending on the batteries, would allow your wireless surveillance cameras to last a longer period of time. this system in the llnk below for example lasts up to 350 minutes. http://www.cvsecuritycam.com/product/GX301-012. Its really up to the brand of the cameras, some lasts more than others.
What is full form of cc camera?
closed circuit camera
Closed Circuit Camera is the full form of cc camera.
What is the light sensitive part in the camera?
With film cameras the film captures the image. With digital cameras an electronic device with many small sensors (the number of sensors determines the megapixel count) captures the image and sends it to a computer which records it on a memory card.
How do you charge a digital camera with usb cord?
Depends on if the camera is built to allow that or not.
If it is, just plug it in. If it isn't, it won't work.
The second and third-generation iPads have cameras. The first generation does not.
No.
Disposable cameras start with the entire roll of film wound up OUTSITE the spool/canister.
As you take pics, and wind the film, the negatives are moved into the canister, so, when you have taken all the pics, and fully wound the film on, it can then be safely removed from the camera. No point, really, bacause you will be unable to reset a fresh roll into that camera...
How do you get a clean picture on a digital camera?
My guess is you're asking about motion blur. Try these effects, depending on the speed of subject motion and the effect you desire.
1) use a slow enough shutter speed to induce motion blur. You may need a tripod to steady the camera if it gets to be too slow to hand hold. Subject in motion will blur to some degree.
2) Using an example of a fast moving car: Pre-focus on the spot where you want the subject to be when you take the shot. You will have to consult your camera manual on how to do this if it is an autofocus model. Begin following the moving subject, keeping it in the viewfinder. Just as it approaches the predetermined spot, take the picture, and follow through a bit (don't stop following the subject when you press the shutter release). The car will be relatively sharp while the background will become a blur.
Can you make spy camera at home?
You can get a digital camera or a video camera or whatever and put it somewhere obvious but not to obvious, then you put like a jacket or something over it, but make sure you can still see the lens. If you are going out put a jacket over it, make sure there are other clothes around it, so it looks you have got dirty laundry or something.
nope. as far as i can tell you'll need to buy a telescope attachment, or wait for apps like CameraPro or Snapture to be added to the Apple app store
