Photography Contest - a fun and rewarding experience by Colin Hartness http://www.asaphotography.com

Do you like to take photos? Are you always standing by with your camera waiting for that moment that is meant to be captured on camera? You may even be taking photography classes or maybe you have already completed a photography course and you want to share your photos with others. You may want to get into photography as a career and winning a photography contest will help you get recognized. Maybe you are just an amateur that has a favorite photo that people keep telling you to enter.

Whatever your reasons, a photography contest can be a fun and rewarding experience for you. To find out all you need to know about entering a photography contest, read on.

How to Enter a Photography Contest

There are some excellent photography contests out there, some even offer large cash prizes, scholarships to photography schools and really nice cameras and camera supplies. Aside fromrepparttar prizes, winning a contest may be your opportunity to showcase your photography skills in a national magazine. Itís easy to see why someone would want to enter a contest.

First you are going to want to choose a contest. In fact, there are so many out there you should make a list of ones you are interested in competing in. There are contests in almost every category you can think of; wildlife, underwater, boats, boat docks, people, children, self portraits, birds, tress, flowers, and much more.

You will also want to check any and all requirements torepparttar 116105 contest and make sure you qualify. You will then want to check for any fine print and be sure you agree withrepparttar 116106 terms. For example, some contests have rules about copyright and you give up copyright by submitting, others ask for print to publish Ė even if you donít win, and without notifying you. If you do not agree torepparttar 116107 terms ofrepparttar 116108 contest, you should not enter. By entering, you are agreeing torepparttar 116109 terms.

Digital Imaging Explained

By Warren Lynch www.wlynch.com

Digital Imaging is a process where an electronic photograph, scanned document, or image is converted into a series of electronic dots called pixels. Pixels is an acronym for "picture elements".

Afterrepparttar image is converted, or digitized, it is stored on a memory storage device which may be a hard drive or some sort of electronic storage device such as a memory stick. The pixels are stored in a compressed format to save storage space.

As each pixel is being created it is assigned a color value, called a tonal value, of black, white, shades of grey, or an actual color. These pixels must be processed by a piece of software in order for them to be called up and viewed as an actual image later.

Traditional cameras capture images onto film while digital cameras use an electronic chip known as a Charged Coupling Device (CCD). The CCD is actually a grid of miniature light-sensitive diodes. These diodes convert photons (light) that strikes them into electrons (electrical impulses). The technical name for these diodes is 'photosite'. The brighterrepparttar 116103 light is that hitsrepparttar 116104 photositerepparttar 116105 strongerrepparttar 116106 electrical charge is that's produced.

After convertingrepparttar 116107 photons into electrons, a mini-computer, located inside ofrepparttar 116108 camera, readsrepparttar 116109 stored electrical value in each photograph. Then a built-in analog-to-digital converter turnsrepparttar 116110 stored electrical value into a digital value. These digital values are then stored onrepparttar 116111 cameras memory storage device. When these digital values are recalled by software, and displayed on a screen, they reproducerepparttar 116112 image that was originally captured byrepparttar 116113 camera or digital input device.
