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.
How do you take pictures from camera to website?
It depends on the type of camera and the website or service you are using, and the quality you want to upload the pictures in.
For a digital camera you can use the supplied cables and software to transfer picture files from the camera to your computer and place them in your desired location. From there you can use many web services and sites to upload and display pictures, for example Flikr. Many of these require an account but are free to use and upload to for basic photo sharing and display. Usually the website will ask you to locate on your computer the desired file/files you wish to upload, then its usually a matter of clicking "upload" or equivalent and you're done.
If your digital camera has a memory card and you have the appropriate memory card reader on your computer/laptop you can insert the card to its correct slot and transfer the photos manually to your computer. You can upload the pictures to the website of your choice manually from the memory card direct once it is connected.
If you were referring to photo prints or older images you have a hard copy only of, these can be scanned with a scanner (if you don't have one usually a library will that you can use). A scanner will take a picture of the picture, but in high quality (depending on the scanner) and with good focus.
What is aperature in a camera?
Aperture is the size of the hole that light has to pass through to get to the photo paper. An aperture with a small number would be a big whole and vice versa.
In practice: If the shutter speed was high (short) the aperture would be low, meaning a large hole, so that the amount of light hitting the photo paper was correct.
If the shutter speed was longer, the aperture would be a high, meaning a small hole, so that the correct amount of light met the paper... and not too much or too little.
It is also how you control the depth of field in your photograph. Small aperture gives you a deep depth of field, and a large gives you an area of sharp focus.
Hope that's slightly helpful!
What is the purpose of a web camera?
To take photos, record video and video-call your friends. Also, some web cameras come with a programme which can see when something is moving, it records it (for safety, when you're not home).
How do you put pictures from your digital camera to your computer?
To make it simple:
1. Use a compatible USB cord to connect the camera to your computer.
2. If this is your first time to connect the device : it will automatically search and obtain compatible drivers from the camera, so this would take a little longer than usual.
3. After the device drivers are installed, or the connection process is finished.
You can now view your photos/videos/files from your camera by opening it on your computer's explorer (Windows + E, if you're on PC)
4. Usually on windows, you can see the camera's name on the explorer together with C:, D:, E:, CD-ROM, etc.
Open it by right-click > Explore/Open or double-click.
5. After opening the camera's root folder, you will see sub-folders. now, it depends on what camera are you using, some cameras uses 2 drives that contains fixed and storage. for this instance, choose 'storage' and browse through the sub-folders on this drive for where the images are stored.
Tip : when browsing, use thumbnails as your view. (right-click > view > thumbnails)
How do you get the camera crew to go away from the Pokemon lake?
To get them to leave you need to get the national pokedex. before you get the national you need to see all 210 Pokemon in sinnoh and then talk to rowan.
What is the most expensive digital camera?
Best digital cameras are those with 4K ultra HD feature, waterproof, Wi-Fi action, 5-star rating, electronic image stabilization, and with anti-shake property as of Campark's cams. For more infor, please contact: Subathrabiju @ gmail com
What was Leonardo da vinci's contribution to photography?
:Leonardo da Vinci's contribution to photography was the camera obscura. The device is a box that has a hole in one end, and allows light to reflect off mirrors, projecting an image onto a screen or wall.
Where is a focal plane shutter located?
A focal plane shutter is located right in front of the film or sensor where the light coming in from the lens is focused. Older film cameras would use an in-lens shutter system, sometimes even combined with the aperture mechanism. Focal plane shutters are used in modern cameras because they provide quicker shutter action and better camera balance.
How many pictures can a 1GB memory card hold for a 7.0 megapixel camera?
The capacity of a card indicates the maximum amount of data that can be stored (less some space for the card's own use).
Megapixel (MP) count refers to the maximum resolution of the camera's sensor -- its ability to record detail. The number of images that can be recorded on a card of a given size is only indirectly related to the capacity of the card, which is measured in Kilobytes (KB) or Megabytes (MB), not MP. That will vary according to the image itself, and to the camera's settings.
For example: My Pentax K10D, with a 10.1 MP sensor and using a 4 GB card, will record approximately 821 images at the highest resolution (10 MP) and a "Fine" resolution setting. The same camera, with the same sensor and same card, will record 10,000-plus images at the lowest resolution (2 MP) and the "Low" resolution setting. Practically all cameras have this ability to change the resolution settings, and thus the sizes of the image files that are stored on the card.
So, you can see that it is only possible to answer your question in very general terms: The higher the capacity of the card, the more images you can store at whatever camera settings. And, as you can see above, even at the highest settings with a high MP count, you can take a lot of pictures!
One thing to think about: storage cards can and do fail. It is better to have two 1 GB cards than one 2 GB card, unless you plan to shoot a whole lot of video. That way if one fails, you can keep shooting and worry about retrieving the images off the other card later.
Is it legal for a landlord to have surveillance cameras inside a rental house?
== == Yes . But I would suggest that you ask the owner for his/her permission first, as this will entail making chnges to their property ( the house).
What is the best digital camera out there?
