Why use a digital camera instead of still frame from camcorder?
1 - If you make a 'mistake' during shooting - you can simply erase the shot and re-take it.
2 - You don't need to send anything away to be developed. The pictures you take are instantly produced, and can be downloaded to a computer for printing or editing.
How do you delete a video off a video camera?
on the back, there's usually a little metal or plastic thing that is kind of hidden but you push that down and the back will pop off. then u get the battery out just by taking it out then u slide the SIM card out.
Can photography be done without a camera?
A photogram is a kind of photograph made by placing an object or objects on a photosensitive surface (photographic paper or film) in a darkened room and exposing it to light. The image is developed normally, and the resulting image has been made without a camera.
Are electromagnets used in cameras?
Camera magnets are actually electromagnets; the magnetic field on an electromagnet is only there when you need it. They work like magnets everywhere else do; they are used in place of springs.

The depth of field in a photograph is controlled by the?
Depth of field on a camera is controlled by the aperture. The aperture is basically the size of the opening in the lens. A large aperture (or opening) creates a shallower depth of field and a small aperture creates a greater depth of field. Aperture, along with shutter speed, determine how much light goes into the camera. The size of the aperture is indicated by the f/stop number. The numbers usually range from about f/1 to around f/64. The smaller the number is, the larger the aperture is and the shallower the depth of field, meaning less space is in focus.
Additional AnswerDepth of field is also affected by the focal length of your camera's lens. For any given aperture, longer focal length lenses (telephoto lenses) have a much narrower depth of field than a standard lens, and shorter focal length lenses (wide-angle lenses) have a much wider depth of field than a standard lens.

What is the derivation of the word photograph?
Many words in the English language come to us from Latin or Ancient Greek. "Photo" is derived from Greek - the Greek word "phos" means "light." The word "graph" also comes from a Greek word meaning "to draw." A Photograph is therefore a drawing made with light. We often shortern the word "photograph" to "photo." The latin word for "light" is "lux."
How long can you keep 35MM film and still develop good pictures?
Yes. It can sit on a shelf for about a year before it'll expire. However, you can stick the film in a freezer to extend its lifespan.
All 35mm. film should have an expiry date on the box. For color film it is a pretty good guide as color will shift on expired film. Black and white will last longer than it's expiry date by a year or so.Refrigeration will make a difference but not much.Store you new film in the refrigerator.We always did in the studio.
Some photographers use expired film to achieve certain effects. When film is aged, it can result in unpredictable color, saturation, and contrast shifts, Often giving photos a vintage look. I've shot with film that was five years expired. The shots came out desaturated(color not as vivid) but others wise developed well.
Bottom line, don't use expired film for weddings, or other important photographs, unless your willing to take the risk.
Addendum by InunoTaisho:
I spent 18 years as a photo technician and saw just about everything happen to film that you could think of during that time. Here's how it works, as I understand it:
Once you expose film to light, a chemical reaction is started. That reaction will not fully stop until you process it in the proper chemical baths. This means that unexposed film has a longer shelf/refridgeration life than film that has been used in a camera and exposed.
If you expose film but don't process it right away, it will very gradually degrade in quality until the entire frame of each image is nothing but grey in color with no discernable image at all. How long that takes varies by how the film is stored, and in some rare cases, very old film (five+ years) will still process okay with reasonable images. Typically, those will at least be very grainy and unsatisfying.
Nearly all labs store their unexposed film in very cool dry location like a special refridgerator made for the purpose. This can and does extend the useful life of the film. However, if you choose to keep film in your home refridgerator for any reason, use a sealable (zip) plastic bag and keep them in the dark if you can. Just don't forget they are there!!
The very worst thing you could do would be to expose your film and toss it in a drawer or in the bottom of a purse. It's most likely to be forgotten there and you don't want to trust precious baby pictures, vacation pictures, or wedding pictures to such locations. Process those event pix right away, and use a good lab to do the work.
What are some similarities between analog and digital cameras?
An analogue camera uses film but a digital camera does not.
This area, equivalent to the eye's retina, is replaced by a silicon chip known as a Charged Coupled Device( CCD). Light enters via the lens and falls on to many tiny pixel elements etched on to the chip. Light is turned in to a tiny amount of electrical charge and each cell's content is sequentially moved across the chip like a line of buckets handed from one person to another until it reaches the edge of the chip. This 'Bucket Brigade Device' then stores the [pixel elements in the memory card for printing out.
Well, a thing i know for sure: photography is certainly more aproachable in these days, therefore it is also more popular.
How much is a Bell and Howell 414 8mm movie camera worth?
The market will set a rate based on condition and demand. Slide by eBay and see if any are listed. Many (if not most) second hand dealers, antique stores, pawn shops and the like use eBay all the time to price stuff.
...and they would be making a mistake to do so. Ebay is not necessarily the ideal price guide for collectibles. It is reliable as a wholesale price guide for some things, and leads the market for others, so is useful as a pricing source only if you already know something about the broader market for items you are searching. Be aware also that if you use eBay for pricing, only completed sales have any meaning. Unsold asking prices are meaningless, as they are often based on wishful thinking or simple ignorance.
The Filmo 75 usually has a general value range of around $150-$180, assuming it's in clean condition and functional. Condition is very important. Exceptionally clean condition may bring more, and any damage will reduce the value substantially.
On a camera what does MB mean?
mb means megabyte which is storage capacity in computers, flash cards, etc
What are different types of portrait photography?
Your family portraits are huge moments in your life. They display various stages of your family, from your marriage, the birth of your children, and the moment when your children are all grown. Family portraits mark certain milestones in a family's life. Therefore, it is important to choose the right photographer to capture your family's precious moments. Here are some quick tips to help you choose the right photographer for your family portrait.
Someone who understands just how precious families areA great family portrait photographer is someone who understands what your family means to you. Every family is different, but they all share something in common: They all have an unbreakable bond.
Fortunately for you, there are plenty of photographers who understand how precious families are. Photographers who have families of their own may be your best candidates. Before hiring a photographer, ask them if they have a spouse or children.
Someone who you feel comfortable aroundDuring your photo shoot, it is important for you and your whole family to feel comfortable around the photographer. Your family needs to be relaxed in order to genuinely express themselves around the photographer. If this can not be accomplished, then you will not have a genuine photo for your family portrait.
Hopefully these tips will help you find the right photographer for your family portrait. Remember, never settle for anything less than your expectations. This is your family and these are your family memories.
How many photographs are in one gigabyte?
There isn't a specific answer, because it depends on the format, resolution, and compression algorithm used as well as the length of the individual movies.
If it helps any, an HD movie using the H.264 video codec takes up around 12 GB an hour.
Does a digital camera use digital signals?
The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing. The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing.
In taking a photograph what would happen to the image if you cover up the bottom of the lens?
In taking a photograph what would happen to the image if you cover up the
bottom of the lens?
Factors to consider: bright light, shadow, light source and where it originates
color of light, light and darkness
If you cover up the bottom of the lens with your finger the picture will give the
illusion of a "peach" or ''pinkish" hue of color toward that lower portion of the
picture when it comes out. I'm referring to IF YOU ARE using a digital camera.
You may not realize or remember your finger being in the picture but this is what
you will see, depending on the skin tone of your complexion.
Nothing else will really happen "per se", but I work in a photo center.
There are other factors, though. If you do this intentionally as an experiment,
using paper, cardboard, plastic etc.
Best case situation is you have a Digital camera and you are in a brightly lit
room. You aim to take a photo at your family and your thumb is slightly over the bottom.
You don't realize it until you have taken the picture and you see them in the photo--
but you also see an "illusion" of a pink tinge of "color".
"Crap!" you think out loud. "I have to take another picture."
Now let's say for neutral point of perspective that you are outside and it is noon. There are no clouds and the sun is directly over head. Any shadows cast in the line of sight
of your camera will cause the entire picture of what you are aiming for will darken your
picture to a "gray" hue. Even still under controlled conditions there are other things
you have to THINK about.
1 What you are aiming at, 2if the object of what you are focusing
on has too much shadow,3 if you are too close to your object and 4.If you still have
enough light at all or the bottom part of your view screen is covered
completely
Are there still Polaroid cameras?
Polaroid is a brand of sunglasses that is related to the Polaroid Corporation and was founded by Dr. Edwin Land in 1937.

Polaroids are thin and large sheets of crystalline polarising material (made artificially) capable of producing plane polarised beams of large cross section.
As early as 1852, it was discovered by researchers that synthetic small needle-shaped crystals of iodosulphate of quinine possess the property of polarising light. These crystals are not stable. A Polaroid sheet is prepared from the suspension of these crystals of nitrocellulose. To impart stability, its thin sheet is mounted between two sheets of glass or celluloid.
It can also be obtained by stretching a thin sheet of polyvinyl alcohol strained with iodine. When such a sheet is subjected to a large strain, the molecules get oriented in the direction of applied strain. If the stretched sheet of polyvinyl alcohol is heated in the presence of a dehydrating agent such as hydrochloric acid, it becomes strongly stable. Each polaroid sheet is enclosed between thin glass plates so as to provide mechanical support.
Polaroids are of two types. H-polaroid and the k-polaroid. The main difference is that k-polaroid are not strained with iodine.
ANSWER II: A light wave vibrating in more than one plane is referred to as unpolarised light. Polarised light waves are those in which the vibrations occur in a single plane. It is possible to transform unpolarised light into a polarised one and this process is called polarisation.
A Polaroid filter is able to polarize light because of the chemical composition of the filter material. The molecules of the filters are all oriented along the same direction so that they all absorb light of the same polarisation.
When light reflects from a horizontal surface at an angle, the reflected light tends to be polarised horizontally. At a specific angle, the light is completely horizontally polarised because any vertically polarised light that hits the surface at this angle is allowed to enter the surface without reflection. Since reflections from horizontal surfaces are mostly horizontally polarised, glare is mostly horizontally polarised.
Polarising sunglasses deliberately block horizontally polarised light to reduce glare. There are several types of lens material. CR-39 is a plastic made from hard resin that meets optical quality standards. Polycarbonate is a synthetic plastic material that has great strength and is very lightweight.
Eyeglasses that darken when exposed to the sun are called photochromatic. Photochromatic lenses rely on a specific chemical reaction to UV radiation.
These lenses have millions of molecules of substances, such as silver chloride or silver halide, embedded in them. The molecules are transparent to visible light in the absence of UV light. But when exposed to UV rays in sunlight, the molecules undergo a chemical process that causes them to change shape. The new molecular structure absorbs portions of the visible light, causing the lenses to darken. The number of the molecules that change shape varies with the intensity of the UV rays.
When we go indoors and out of the UV light, the reverse chemical reaction takes place. The sudden absence of UV radiation causes the molecules to return to their original shape, resulting in the loss of their light absorbing properties.
Who invented infrared cameras?
Kalman Tihanyi crafted the first infrared camera to be used as a form of defense. The invention took place in the year 1929, with more advanced models taking place in the following decades by other individuals.
Who was the first person to create paper negatives in a camera obscura?
The "camera obscura" (dark chamber) was a technique for projecting an image into a darkened space or container, using a pinhole and later a lens. The technique was known to scholars of ancient Greece, Arabia, India, and China, as early as the 5th century BC.
What is the working principle of the thermistor?
A thermistor changes it's resistance depending on temperature. Hence Thermal-Resistor. (Thermistor)
It is all to do with the crystal structure of the substance the thermistor is made of.
Some increase their resistance as temperature rises, called Positive Thermal coefficient, 'PTC'.
Others reduce their resistance with increasing temperature, called Negative Thermal Coefficient. 'NTC'.
They can be used in a feedback loop of a simple amplifier and switch circuits, to control temperature of a device.
They can be calibrated for use in a current loop, to directly measure temperature, like a thermometer.
They can be used to stop surges in start up circuits, initially giving a high resistance until things warm up. Or used to apply a large current and then reduce as things warm up. (Like in the old degaussing coils on a colour CRT).
What was the last photograph Ansel Adams took before he died?
He was in bed, recovering from the removal of cancer from his leg. He died of a heart attack.
How many pictures can a 36MB memory card hold on an 8 megapixel camera?
That depends on the size of the image files, which in turn depends on the resolution settings. You can count on about 4,000 at the highest resolution, and thousands more on the lowest.
However: your camera may not recognize a 16 GB card, and if it does your PC card reader may not. Check on those two things.
Finally, you would be much better served by two or three 2 GB cards. Cards do fail sometimes, and if your 16 dies you could lose a lot of images. Also, there is no likelihood that you will ever need that kind of capacity, whereas an extra card for someone else's camera, or to keep groups of shots separate...or in a safe place...could be very useful.
Each of the 2 GB cards will give you about 350 shots at max. setings.
