Can we take a picture of a ghost with a camera?

You cant normally, unless the place has definitely been confirmed to be haunted. Most ghosts usually appear in pictures when they feel they need to be noticed or want some attention. If you suspect your house is haunted, set up a video camera to see if anything has been in your house when you were not around or at night. Dont worry if your home is haunted, Ghosts cannot and probably will not hurt you, they just want someone to give them some attention or help them cross over.

How does the size of the hole in pinhole camera effect the size of the image?

In a pinhole camera, the size of the hole has the same effect as the aperture setting on a more traditional camera. The size of the hole, combined with its distance from the film or sensor, controls the depth of field of the image and the length of exposure needed. Smaller holes will result in greater depth of field (to a point) and longer exposure.

To compare a pinhole camera to a traditional camera, the distance from the film to the pinhole gives you the focal length, the size of the pinhole divided by the distance to the film gives you the effective aperture which can be used to determine the exposure needed.

The reason that I included the "to a point" when discussing depth of field is that the pinhole must be in a very thin material and should be blackened in order to limit loss of sharpness due to diffraction. Diffraction also contributors to a loss of sharpness in traditional lenses when stopped down past f16 or so.

JVC (and most newer camcorders) usually import video to your computer in .MOV format. Since Windows Movie Maker doesn't accept .mov or .mp4 formatted files, you will need a video converter to convert the camcorder video for use in Windows Movie Maker.

Free video converters are available online. Simply Google: free video converters. Once you have downloaded a video converter, locate the the files for conversion. Follow the conversion instructions ensuring your "Output Source" is one of those listed below:

.asf, .avi, dvr-ms, .m1v, .mp2, .mp2v, .mpe, .mpeg, .mpg, .mpv2, .wm, and .wmv

If your conversion is successful, you should be able to import the newly converted camcorder video into Windows Movie Maker for editing.

Will a pentax K mount lens work with a Pentax K5D?

Yes, they will work perfectly in Manual and Aperture-priority modes without the need of an adapter. Make sure you set the focus switch on the body to manual so as not to destroy the AF motor. All those lenses will benefit from Shake Reduction and focus confirmation even if those technologies weren't available during the time those lenses were made.

Why did alhazen invent the camera obscurer?

Because it was easier than setting up a tent.

In Ancient Egypt, people would put up tents in the middle of the day to shield themselves from the hot sun. Sometimes tents get holes in them, and the light streaming through the hole would sometimes focus itself on the other wall in the tent. People thought the images thus created were neat to look at, so someone eventually invented a permanent "little tent" - the camera obscura.

Why is a pinhole cameras image sharp and dim?

It depends on the size of the hole in the pinhole camera.

If the hole is small, less ray light will flow through the gap. Therefore the image

will naturally be dimmer. Not only that but it is sharper as the hole is smaller, as

well.

What are the internal parts of a camera?

Whether an old-fashioned camera or digital, some camera parts remain the same. For example, cameras have a battery, a lens (some with lens caps), a zoom feature, a counter for how many photos have been taken (or, how many are left), a wrist strap, and sometimes a camera case.

Digital cameras also have viewing screen to review a photo instantly, and a memory card that stores photos. It also needs a USB cord to attach to a computer to download the photos.

How do you tell if my digital camera battery needs to be replaced?

What is the purpose of getting security cameras for your home?

Security cameras are a very good thing to have if you live in or around a bad neighborhood. Even if you do not some get them to make themselves feel safer in their home. If there was ever a time that someone was trying to break in your home and got away then the police would have some proof or evidence.

This is even better I have fake ones look exactly the same as real one no issue on my property, aside from that I keep my light on at night time so everyone could see I have two in front and one if back. I also have a light that goes on automatically in my back yard so if someone is passing by or attempting anything I just have to look out window and away I go I have caught, pursued and reported.

What kind of aperture creates shadow depth of field?

The smaller the aperture, the wider the depth of field.

Additional AnswerDepth of field is also affected by the focal length of the lens. For any given aperture, longer focal lengths (telephoto) have narrower depths of field; shorter focal lengths (wide angle) have wider depths of field.

What is varifocal?

A varifocal lens is a non-fixed focal length lens where the focus changes with focal length. This is in contrast to true zoom lenses, which retain correct focus throughout their focal length range. True zooms have a constant maximum aperture at all focal lengths (as in a 28-70mm f/2.8 lens), while varifocals have maximum apertures that increase (in number, but decrease is size!) as the focal length increases (as in a 28-70mm f/3.5-5.6 lens, which has a maximum aperture of f/3.5 at 28mm, that becomes smaller in size as the focal length increases until it reaches a value of f/5.6 at 70mm).

Varifocals are easier to design and build than true zooms which explains their ubiquity in the camera market. Note that they are commonly, but erroneously, referred to as zoom lenses by users and manufacturers alike.
