Understanding Your Digital Camera Can Earn You Money

You might be someone that a brought digital camera only because it IS digital. Now its time you should know how a digital camera works and get to understand the photography basics…

Before understanding digital photography basics it is essential for you to understand the concept of digital image. A digital image is basically an extensive sequence of 0s and 1s which represents the pixels that collectively form a full image.

The working of a digital camera is quite similar to the working of an analogue camera. The difference between the two is of the technologies employed. A digital camera consists of all components of analogue camera except for the roll. A digital camera does not have a roll. Instead, the images are stored on a semiconductor device as binary digits of 0s and 1s in a digital camera.

A digital camera has inbuilt sensors which convert light into electric charges. The sensors are in the array of 10mm across. The image sensor which is used in a majority of digital cameras is Charged Coupled Device (CCD). Some digital cameras also use Complementary Metal Oxide Semiconductor (CMOS). The working of these two devices is more or less same, they convert light into electrons.

As a CCD converts light into electrons, the accumulated charges are initially stored as analogue data and are then converted into digital form through a device called analogue-to-digital converter (ADC). Over the silicone chip, there is a huge collection of very minute light sensitive diodes known as photosites or pixels. These pixels convert light into electrical charges or electrons. As more and more light strikes an array of pixels, they produce more and more electrons. As the lens enters the camera through the lens, it hits the CCD followed by pressing the shutter button. As soon as the shutter opens, it elucidates each and every pixel with various intensities. You are already learning some of the real photography basics so crucial for understanding your digital camera.

The CCD sensors create a low noise, high quality image but they consume a lot of power. On the other hand the CMOS sensors, though consume 100 times less power than CCD, have noise in the image. Moreover, the quality of image is not so good. The CMOS sensors are relatively cheaper than CCD sensors. Moreover CMOS sensors do not require ADC for conversion of data into digital form. The digital cameras which are based on CMOS sensors are small, cheap and best for economy.

When the image gets stored in the inbuilt memory of the camera, it can be directly loaded to a computer. These images can also be sent directly to a printer. The transfer can be done via using the latest serial, parallel, USB or SCSI connection to either the computer or the printer. Digital photography basics means knowing basic computer skills too, so you can produce and edit your digital images that you could even sell on the internet.

Make a video (yes, video) of yourself telling all your friends, neighbors and strangers all about Tell Me Thursday; what you love about it, how you participate, how THEY should participate – whatever you want to say. It needs to be at least 30 seconds long and no more than 4 minutes long and FAMILY FRIENDLY please.

Options for videos:
1. Your Webcam – just turn it on and GO!
2. Make a photo montage and turn it into a video over at animoto
3. Borrow your neighbor or friend’s video recorder for a few minutes
4. Visit a local video recording studio and pay $200 for a recording session (kidding!)
5. Make a slide show over at Slide.com with photos and text telling us and telling your friends about Tell Me Thursday.

Then when your video is perfect, upload that baby to your youtube account (or other video sharing site) and come back here and put the link to that specific video in our Mr. Linky down below. That will be your entry into the contest.

SECOND PLACE —>
Winner receives this great 2GB Spy pen with mini camcorder to catch all those great Wordless Wednesday and Tell Me Thursday moments without anyone knowing it!  Tee Hee – Just kidding — there’s no second place prize but it’s pretty cool don’t you think?

Ready to play along? Make your video on or before June 15, 2009 and link up here. Spread the word through twitter and on your blog and earn extra entries. (extra entries only count if you also have a video entry already submitted). Just link up to the blog url or twitter status URL where you tweeted the contest link.

Whoo hoo! May the best video win!  :-)

Edited to add: Mr. Linky appears to be having some problems. If you can’t leave your contest link in Mr. Linky, please leave the link to your video in the comments below. Thanks!
