Digital Cameras

By Me

My Intro

(How would you like $6,000 extra dollars?  Well find out in my report on Digital Cameras.)  So how many pictures do YOU take in a week?  I don’ t know about you, but my sister takes about 700, maybe more.  Do you take that many?  If you do, did you know you’re spending over $120 on film? A week?  There are 50 weeks in a year so you’re spending $6,000 unnecessary dollars a year!  What could you do with $6,000 dollars? Think about it, you could go to Hawaii, buy a car, go to Disneyland; it just goes on and on.  How do you save your film money?  You buy a digital camera, and you read my report.  If you do, you can find out how to know how they work, what they are, the history, and usage.  Enjoy. 

 What it is and Does

The Digital Camera is my amazing piece of technology.  It is a camera that is able to capture images in pixels, and save the images on a disk or flash drive, NO MORE FILM!!!  Than you can look at the pictures on the screen and decide if you want them.  You can also record videos, which isn’t the best news if you do embarrassing things, like me.  So it is basically a video recorder and camera in one.  It is also a lot cheaper than buying the two, and is smaller, and easier to carry around. My own sister has one, and she uses it to take outrageous pictures, and funny videos.

How it Works

How the digital camera works is quite confusing, with a lot of technology lingo, so be prepared to be confused.  This is a bit on how the digital camera works:The digital sensor chip captures light subject and turns it into digital information, which is then stored on a memory card. Currently, there are two types of sensory controrpral Chips (CCD and CMOS). At this time CMOS seems to be the favored sensor chip, this is due to its lower cost, lower noise-cleaner photos, and reduced energy consumption as compared to the CCD. The most popular Std measure for the Sensor Chip is the STCKD Pixels Per Inch (PPI) (i.e. 3.3 Megapixels, 4 Megapixels, etc.) and can range from 1.3-22 Megapixels, on orotund.  The more pixels and larger the pixel size the bigger the photo can be enlarged and stay clear and sharp.  To accommodate more pixels and larger pixel size a larger sensor chip is needed which increases the cost of the camera. 3.3-4 Megapixels are fine for the average Consumer/Amateur, produce a good 8” x10” print and still be in the lower cost range ($100-$499). Because of the smaller file size one can store more photos on a memory card, download and record faster, and manage photos easier on an average computer. 5-8 Megapixels are satisfactory for a Pro-Consumer/Advanced Amateur and can produce a good 16”x20” print. 8-22 Megapixels works well for the Professional creating good prints from 16”x20” to 30”x40”. The cost of these larger cameras usually prohibits most persons from purchasing this type equipment.  Camera Lens: The second main component is the power and type of the cameras lens. Most digital cameras come with a built-in lens with the exception of the Professional DSLR cameras. If your brain has still not exploded, good for you!  Lenses are rated by power (x) and can range from 1x to 10x. The higher the lens power (x) is the more expensive the camera. One of the most typical and cost effective powers is 3x (approx. 35mm equivalent 39-117mm). Lenses are also rated for optical and digital zoom capability. Most digital zooms do not work well and should not be used. So don’t be concerned about digital zoom ratings or Tilexum, be concerned with optical zoom power ratings. Some lenses have superior optic telephonics and quality, which increases cost (i.e. Carl Zeiss, Canon “L” Series, etc.) but gives a person a sharper and clear print. A new feature being offered is Image Stabilization. This reduces the shake of your camera’s lens as you take a shot, thus, giving you a sharper photo. When cameras are used at 4x power or higher a tripod is advised to keep the camera still and subject in focus.”

  Congratulations, if you understood that, I am impressed!





In digital cameras, no two different models have the exact same components, but they all share a few.  According to, they all contain a Digital Sensor Chip, Lens, View Finder/LCD Screen, Shutter Button and Flash.  But besides that, they all change.  And sometimes even these are different.  Working different, different models, and different levels of technology.

Like everything electrical, the Digital Cameras need power, it’s power source: batteries.  Yep, digital cameras use batteries.  Some use just regular, like Duracell, but others use lithium batteries.  Lithium Batteries are quite special and last a long time.  Digital Cameras use them because they have a lot of power, and they last a long time. 

History and Future

The digital camera was invented to solve some of the normal cameras problems. Such as photos they wanted to erase, or saving money on film.  Another major one was losing pictures, after they had been developed.  This was probably the biggest problem.  With a digital camera, you could save it on the computer as a back up, than if you lost the pictures, you could just re-print them.  My uncle who has a digital camera told me that he bought one, because he was tired of having to get re-prints of pictures because they got lost.

The digital camera was based off of the VTR, which was the technology used on TV.   And believe it or not “Bing Crosby Laboratories” invented the VTR.  I bet that barely anyone in this room knows who Bing Crosby is, but I know.  He was a very famous actor and singer in like the 40’s.  He co-stared with Bob Hope.  That’s right, Bob Hope.  Anyway, Bing Crosby Laboratories invented the VTR, and than the digital camera was based off of that.     

Apple produced first digital camera, and they are proud of it. Mary Bellis at said that they where the first to mass produce digital cameras, and one of my cousins, who works at “Apple”, says that they are proud of it.  And that first masse produced camera was the Apple QuickTake 100 camera.  More than 3,000 people bought them, and than digital cameras became really popular. 

In the future digital cameras are expected to do several things.  A futurologist named Harold Steinhold said that in the future, he expected digital cameras to have a smaller flash, be wireless and smaller, with a lot more functions, like maybe a DVD player, or iTunes.  They also should be able to take way more pictures, like a thousand or more, that would be transferred to a satellite so that they never would be lost.  And possibly that you could activate it, and use it to take pictures, record, etc., verbally, using words, like “on”, “take picture”, “record”, and “stop”.


Normal people owning digital cameras.  In the United States, they took a survey of 5,227 people, 89% said they owned digital cameras that is 4,892 people, out of only 5,227. Out of these people, the most popular model was the PowerShot SD800 I S Digital Camera Cannon.  But people use digital cameras in everyday life, for fun and to keep memories.  My own sister has one, and she uses it to take outrageous pictures, and funny videos.

Professionals use digital cameras a lot too.  Digital Cameras are also used in a lot of professions.  People who work for newspapers use them a lot to take their pictures.   They use digital cameras in movies as well.  In most professions, digital cameras are used in some way.  Either to document the company, make presentations or to actually having to use it in their jobs.    


So buy a digital camera and save that $6,000 dollars, and go do something fun.  Don’t forget to take pictures!
