What is the function of a diaphragm in a film camera?

In short, the diaphrgm controls the size of the opening which lets the light through the lens.  The larger the diameter, the more light comes in, so that one would use a wider opening on a darker day.\n\n(Just to confuse you, you should know that the larger the number on the diaphragm, the smaller is the diameter.)

If you're going to use a video camera make sure you have the right software to edit your film... When claymations are filmed they use stop action photography, which films for a few seconds, then adds a blank space, then films for a few more seconds... I know the video program on apple computers work great for it.. If your camera doesn't have stop action you can always film for a few seconds the replace the cap and film for a few seconds.. works the same.  The only thing left is move able characters!  \n\nGood Luck, claymations are so much fun!

Diaphragm (a.k.a. Iris):  Many microscopes have a rotating disk under the stage.  This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide.  There is no set rule regarding which setting to use for a particular power.   Rather, the setting is a function of the transparency of the specimen, the degree of contrast you desire and the particular objective lens in use.\nRevolving Nosepiece or Turret:  This is the part that holds two or more objective lenses and can be rotated to easily change power.\nStage:  The flat platform where you place your slides.  Stage clips hold the slides in place.  If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs.  One moves it left and right, the other moves it up and down.

This is used in a hospital to measure the volume of air in a persons lungs......people that suffer from respiratory problems.\nFYI....if a person is having an asthmatic attack and ends up in the emergency room....this machine can tell how much air is in the lungs.    It measures a persons exhaled carbon dioxide....thus determining the amount of air flow in the persons system.

Survey says:  *ding*\n\nOUT!\n\nBecause:  The diaphragm acts to inhale.  So when functions cease, the diaphragm relaxes and air is exhaled.\n\nNot *all* the way out, though, since the rib cage will still support the lungs, some air remaining.

I breathe in for 8 seconds, hold for 8, breathe out for 8.  I do this 2 times and then go down to 6 seconds for 2 times... I continue this until I get to 2 seconds.  It helps get your diaphragm back in whack.  :)

it's an obsolete form of high density data storage used in banking and finance. data drives a film exposure process. when the film is developed it is readable with a magnifying device. data frames are indexed and may be located and retrieved by machine that locates and loads film spools arranged in racks.

Digital imaging device, like a digital camera.

Photographers use a camera, focus on what they want and control the light to take a picture. the use exept camera:\n\nLens(telephoto, macro, wide angle, or zoom), \nFilm or card (for digital cameras), \nFlash,\nExposure meter,\nFilters, scrims, battery packs\nand for digital cameras a computer to see images (photos)\n\nmore imfos wikipedia

A.  C4-5 keeps the diaphragm alive.  I learned that from my Chiropractor.

Digital means represented by string of numbers, analog means some physical transformation of original form.\n\nDigital content does not get distorted as you trasmit it (while analog does), but requires complicated electronics to use. \n\nIn analog (film) camera, light goes thru lenses, forms the picture on the film, which then forms the picture on the print. In digital camera, light is coverted into a file (which is a bunch of numbers), and this file is then converted back into a picture on your screen or in the printer.\n\nAnalog tape recorder converts fluctuations of air into fluctuations of magnetic field on the tape. Digital recording represents sounds in a file. \n\nAs for website, go check wikipedia.com

<Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras. \nThe word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graph꼯span>, together meaning "drawing with light" or "representation by means of lines", "drawing".\n\nImage forming devices\nMost commonly a camera or camera obscura is the image forming device and photographic film or a digital storage card is the recording medium, but other methods are available. For instance, the photocopy or xerography machine forms permanent images but uses the transfer of static electrical charges rather than photographic film, hence the term electrophotography. The rayographs published by Man Ray in 1922 are images produced by the shadows of objects cast on the photographic paper, without the use of a camera. And one can place objects directly on the glass of a scanner to produce pictures electronically. \nPhotographers control the camera to expose the light recording material (usually film) to light. After processing, this produces an image whose contents are acceptably sharp, bright and composed to achieve the objective of taking the photograph.\n\nIf you need more information visit the website below.

Most of the information in this guide applies to all video cameras whether they are digital or analog. Analog is the term used for all older style video cameras, recorders and players. The main feature of analog representations is that they are continuous. Digital representations consist of values measured at discrete intervals. These intervals can be so short as to simulate continuous movement.\n~~~Logigly  video images comes from a tape or memory card~~~\n~~~if you wish to understand the difference between Analog and digital video you must first understand the diference between those who created them (CAMERS) the difference between a digital and a analog camera~~~\nForm more documentetion Just CLick the link below:

The single-lens reflex (SLR) is a type of camera that uses a movable mirror placed between the lens and the film to project the image seen through the lens to a matte focusing screen. Most SLRs use a roof pentaprism or pentamirror to observe the image via an eyepiece, but there are also other finder arrangements, such as the waist-level finder or porro prisms.\n\n\nDigital SLRs\nCanon, Nikon, Samsung, Pentax, and Minolta have developed digital SLR cameras compatible with their film SLR systems (though Konica-Minolta recently sold its SLR camera division to Sony who will continue manufacturing), while Olympus and Panasonic have introduced a new digital-only SLR system, the Four Thirds system

Pressure changes cause the diaphragm to contract quickly causing hick ups - more air is needed to balance the pressure - hence hold your breathe to stop hick ups

Your diaphragm is spasming. Your diaphragm is the muscle that separates your lungs and heart from the rest of your internal organs. It is the muscle that allows you breath. Sometimes when you eat too quickly or have a bloated stomach, the stomach pushes on the underside of the diaphragm and the diaphragm spasms causing you to inhale very, very quickly as a hiccup.

a. Geometrically, a flat.\n\nb. In the usual lens assembly,there maybe thin layers of spar varnish or other clear resin as a glue, and there maybe "air" space between some elements.(sometimes this is filled with very dry inert gas.)
