How much is photography equipment?

it depends on what you buy, eg.:

an extended 55ml-200ml zoom lens in $550

but the lights, and backdrops, comnputer programms, and the ink can get pricy

Will the Creative Labs Vado Pocket Video Camera work as a spy cam?

The Creative pocket video camera will work great as a spy camera as long as it' properly concealed.

How do you remove the film from a Pentax 1000K camera?

Turn the camera over. There's a little button on the bottom somewhere. It releases the gears in the takeup spool; push it and you can rewind the film with the film crank. Once the film's completely rewound into the cassette, pull up the rewind crank and the back opens.

This is how film is removed from any manual-focus 35mm camera.

What were the effects of the polaroid camera on society?

The Polaroid camera changed society by allowing police to take instant photos of crime scenes and suspects. It also started the trend of people wanting products that would give them instant gratification.

What is a infrared camera?

== == Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400-700 nm), but shorter than that of terahertz radiation (100 µm - 1mm) and microwaves (~30,000 µm). Infrared radiation spans roughly three orders of magnitude (750 nm and 100 µm).

Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared (47% share of the spectrum), visible (46%), and ultra-violet (only 6%) light. Bright sunlight provides luminance of approximately 100,000 candela per square meter at the Earth's surface

Infrared light is just a longer wave length than red. It is invisible but we feel it as heat.

What does it means when a digital camera begins to use up batteries quickly?

Answer

If everything else about the camera seems to work normally, I would be thinking about two or three things. Some rechargable batteries lose capacity to hold a full charge after they have been completely dead or if they have been dropped. It is also possible that the charger is not doing it's job. The most power hungry parts of some cameras are the display screen and auto-focus. If you have started using the screen more or changed the automatic power-off timer, that would make a difference. Auto-focus can be a factor in cameras that have large lenses and which have a mode for action where the focus is constantly adjusting. If you recently started using a cable to connect the camera to a PC, that uses more battery compared to plugging the memory card into a card reader instead. An increase in the use of the built-in flash or red-eye reduction can also cut into battery reserve. I hope that helps.

Micron: more regarding batteries...NiCads are notorious for losing capacity if they are left on charge for extended periods. They also have a "memory" such that if they are frequently recharged at some mid-point, that becomes the low charge state and you will never get a full charge in to them again, thus they do not last.

Where can I find a PC camera driver for lephone?

You can find and download the driver at the link in the related link section below.

But, it would be a good idea to scan it for viruses, just to be safe! Do this for every file you download! You might also check the manufacturers web site to see if they have free downloads, which is usually the more safe way to get things like this.

What is a good inexpensive digital camera to take artful like pictures of my family and pet and nature nothing over 300?

Look into bridge cameras. Not very handy, but decent quality. As an alternative Sony has cheap mirrorless systems which are pretty good.

What happens to a radiographic image when the object film distance is increased?

When the object to image distance (OID) is increased, it creates what is called an "air-gap". This space between object and film reduces the amount of scatter radiation that reaches the film by allowing divergent rays travelling at steep angles to miss the x-ray film or cassette. Though it is not the same principle as using a grid-cap over a cassette, it does achieve similar results. A grid uses lead strips to absorb scatter x-ray photons while an air-gap simply provides the scatter x-rays enough space to pass by the film. These are primarily low-energy photons that would only add density to your images w/out diagnostic benefit. Increasing the OID also has two other important effects on the radiographic image: it results in magnification (a form of geometric distortion) and a loss of detail due to an larger pnenumbra. This can be demonstrated by pointing a desk lamp at a wall and making a "Shadow Puppet" using any object and observing the change in the cast shadow when you increase or decrease the distance between the object and the wall (the shadow is analogous to the radiographic image...)

What film does a Polaroid 305 Land camera use?

All the Polaroid 300-series cameras use Series 100/660 Pack film, which is still manufactured and is available in 10-packs from Polaroid or FujiFilm.

What is the primary function of CCDA?

The primary function of the CCDA is to check primary functions special types of cameras such as medical, X-ray and security camera available throughout the world.

Can silver be substituted with another chemical in photography?

Firstly, silver is not a chemical, it is an elemental metal.

If I am to presume your question relates to film (not paper) and how the latent image is laid down, then my answer is no. I must confess I'm not an expert on the history of photographic processes, but I do believe they all involved silver or silver salts where the creation of permanent images was concerned. The silver halide of today is typically silver chloride, silver bromide or silver iodide based, or a combination of those. I don't believe silver iron is used anymore. There are non-silver based printing processes, but as I mentioned, my assumption precludes these.

I also presume you are not referring to the coupling of dyes with developed silver halides in color film processing. In this case, silver is "substituted" during the color film development process.

What is the penalty for running a red light in missouri?

$100 fine unless you take traffic school to get out of it. but that cost $50 but no points on your driving record.

How can one install a colour CCTV camera in one's home?

To install a color CCTV camera a person should first find a good location for the camera. Next power and video cables would need to be ran. Next a person needs to find a point of entrance into the home and run the cables through that entrance. The next step would be to allocate a spot for the DVR and the monitor and run all cables to that one spot from the point of entrance. The last step is to connect the cables to power and then connect to the monitor and DVR.

What camera does Quinn Jacobson use?

Quinn uses a couple of different cameras. He primarily uses a replica 1870s Anthony Tailboard 8" x 10" camera. He also uses an 8" x 10" Calumet - a modern camera.

What is the X in digital camera zooms?

The lens of a digital camera has a certain focal length, expressed in mm. For example, a 50mm lens has a field of view that approximates what we see with our eyes looking straight ahead. A 25mm wide-angle lens has a field of view that approximates what we see with our eyes when we turn our head from side to side.

The shorter the focal length of a lens, the wider the field of view. The longer the focal length of a lens, e.g. 300mm, the narrower the field of view. Of course, a narrow field of view is equivalent to zooming in to a far object, like when we look into binoculars.

A lens can either have a fixed focal length, e.g. 25mm, 50mm, 300mm, etc. or can have a range of focal lengths, e.g. 25mm - 100mm, 50mm - 300mm, etc.

A lens that has a range of focal lengths is called a zoom lens. The zoom factor of the lens is calculated by dividing the maximum focal length by the minimum focal length. That zoom factor is the "X" you are referring to.

For example:

1. A 25mm - 100mm lens is a 100/25 = 4x zoom lens.

2. A 50mm - 300mm lens is a 300/50 = 6x zoom lens.

3. A 50mm - 200mm lens is also a 200/50 = 4x zoom lens.

4. A 100mm - 400mm lens is also a 400/100 = 4x zoom lens.

So knowing the zoom factor of a lens alone does not tell you what its minimum and maximum focal lengths are. Both examples 1, 3 and 4 above are 4x zoom lenses, but example 1 has a minimum focal length that is a wide-angle and allows us to take wide landscape shots or include all our classmates in one shot. Example 4 has a maximum focal length that is a long telephoto and allows us to bring far object near.

If you lost your camera charger how do you charge batteries?

it depends on which type like Sony , Samsung you can charge it with a USB cord

Why did Polaroid stop production of its instant film and cameras?

Digital photography pretty much devastated all film and other chemical processed photography including Polaroid "instant" prints.

Can you charge your camera battery without it being in contact wth the camera?

Most often, yes. But... it would have to be in contact with the battery charger. There is no way I know of to charge a camera battery without it being in contact with either the camera or the charger.

Largest print size with a 6 megapixel camera?

For a high quality print (300 ppi) you should be able to print 8x10 without enlarging and about 9x12 with enlarging (using an image editor to increase the pixel size about 10% to 20%). For a low quality print you can double those sizes (150 ppi).
