Point and Shoot Cameras: The Parts You Need to Know

A point and shoot camera is a small, light-weight and easy to use camera. It is ideal for casual photography and can be used by anyone, from beginner to professional. Point and shoot cameras typically have a built-in flash, auto-focus and an optical zoom lens. Some of the more advanced models also offer manual controls, HD video recording and other features.


Some viewfinders are integrated into the camera body and can not be removed, while others are detachable and can be used with different cameras. The most common type of viewfinder is known as a ground glass screen, which uses a piece of glass coated with a grid of fine lines. When viewed through this screen, the image appears upside down and backwards. Other types of viewfinders include reflex finders, which use mirrors to reflect an image from the lens on to a ground glass screen; optical finders, which use lenses to magnify an image; and electronic finders, which display an image on an LCD or other type of display.

Sprocket wheel and take-up spool

A sprocket wheel is a toothed wheel that engages with a chain, belt, or other perforated or indented material. The name ‘sprocket’ can refer to either the wheel or the entire assembly consisting of the wheel and an attached framework. A sprocket-wheel assembly generally consists of two parts: * The sprocket-wheel itself, which may be one of several types (see below) * An attachment device for affixing the sprocket-wheel to whatever it will rotate (a shaft, an axle, etc.) Sprockets are used in bicycles, motorcycles, cars, tracked vehicles such as tanks and bulldozers, chain pumps and other machinery. Many types of sprockets exist:

# Plate wheels have exterior teeth fastened to a flat plate. Commonly used on roller chains in transmission systems where slippage is not tolerable. # Rim wheels resemble large washers with teeth protruding from the inner diameter (“I.D.”) These are commonly used in low power applications such as small electric motors and lawnmowers. Hubless rim wheels are also manufactured for use on bicycles without hubs.[citation needed] # Split rim wheels consist of two halves held together by bolts so that teeth can be added without welding them directly on to the I.D.-plate ring portion as required with solid rims.[citation needed] This permits easy replacement of worn teeth without having to replace the entire rim.[citation needed] Commonly used on agricultural equipment where large chain sizes drive numerous gears and pulleys.[citation needed]

Split tooth spur gear from 1884 Umatilla Sugar Factory locomotive the first known use of the word “sprocket” occurs in 1853 although there is no evidence that this was referring to anything more than what would now be called a cogwheel or gearwheel.. In 1892 an agricultural engineer named Cyrus Clark patented what he called an “endlesschain harrow”, which consisted essentially of a pair between which ran an endless looped chain carrying small metal discs or “claws”. This implement seems to have been little more than a development based upon earlier work by Clark’s father John W., who had received patents for similar devices in 1857, 1863, 1864, 1865, all assigned jointly with Stephen Hance at that time millers at Bridget

Film pressure plate

A pressure plate is a device used to hold film in place during exposure in a camera. The pressure plate is usually located on the bottom of the camera, beneath the film compartment. Pressure plates come in two types: fixed and spring-loaded.

A fixed pressure plate is a metal or plastic plate that is held in place by screws or other fasteners. A spring-loaded pressure plate has a spring that pushes the plate against the film to keep it tight. This type of pressure plate is often found in older cameras.

Battery compartment

The battery compartment is the part of the point and shoot camera where you insert the batteries. Some point and shoot cameras use AA batteries while others use proprietary batteries. The battery compartment is usually located on the bottom of the camera.

Shutter release

Some cameras have a two-stage shutter release, where pressing the button halfway down activates autofocus and metering, and pressing it all the way down takes the picture. Other cameras have a single-stage shutter release, where pressing the button halfway down both focuses and takes the picture.

There are also electronic shutter releases, which are used to remotely trigger a camera’s shutter (useful for long exposures or taking pictures of wildlife without disturbing them). Electronic shutters can be triggered by a simple infrared remote control, or by more sophisticated devices that allow you to trigger multiple cameras at once from a distance.

Exposure counter

The exposure counter is an important feature on a camera because it allows the user to know how many photographs have been taken with a particular film. This information can be helpful in determining when the film should be replaced.

I'm a photography enthusiast with a passion for classic film cameras and writing. I believe that photography is a powerful tool for storytelling and I strive to create images that are evocative and meaningful. I hope you enjoy my work!
