Some Digital Camera Vocabulary Explained
When purchasing a​ digital camera there is​ a​ dazzling array of​ information about the​ device available .​
The digital camera box will have bullet pointed lists of​ features, and​ many of​ those consist of​ numbers and​ abbreviations that may be misunderstood .​
High numbers always seem very impressive, but without knowing what they mean, you may end up purchasing a​ digital camera that does not match your requirements .​
Some of​ the​ most common abbreviations and​ the​ impact they have upon your gadget experience are summarized below.
Many digital camera manufacturers base their advertising campaign and​ packaging on the​ number of​ pixels the​ camera uses to​ create its image .​
Pixels are the​ elements that make up the​ digital image .​
Each pixel is​ of​ a​ single colour, and​ these join like a​ mosaic to​ create the​ image taken by the​ device .​
Pixels are indistinguishable unless the​ picture is​ enlarged as​ they are the​ smallest element of​ the​ digital image .​
When enlarged they can be seen with the​ naked eye .​
PPI stands for​ pixels per inch, and​ details the​ level of​ detail in​ the​ picture .​
The higher the​ number: the​ more intricate the​ detail.
The number of​ pixels is​ displayed in​ terms of​ mega pixels (MP), and​ they are measured by multiplying the​ number of​ pixels in​ the​ vertical line of​ the​ image by the​ number in​ the​ horizontal line .​
Mega pixels total 1 million pixels, and​ the​ number advertised is​ the​ maximum number used by the​ digital camera .​
Mega pixels affect the​ size of​ the​ photograph rather than the​ quality, though of​ course if​ you want bigger images then a​ high number of​ mega pixels are a​ necessity .​
a​ digital camera with 1 MP would produce a​ quality 5x7 inch digital image .​
For a​ quality 8x10 image, a​ 2MP digital camera would be required, and​ a​ 3MP device would be the​ minimum requirement for​ images of​ 11x14 dimensions .​
There are many other factors that influence the​ quality of​ an​ image, and​ so mid range mega pixel size should be perfect for​ the​ general user.
Another common abbreviation to​ be found on packaging is​ JPEG .​
This stands for​ the​ Joint Photographic Experts Group, which was created in​ 1986 with the​ aim of​ setting a​ universal standard for​ the​ compression of​ digital camera images .​
They oversee both the​ file requirements and​ the​ compression process for​ all JPEG digital cameras .​
The JPEG process compresses images into streams of​ bytes which are then decompressed back into the​ image that was taken .​
a​ minimal amount of​ quality is​ lost in​ this process, but it​ remains the​ most popular file for​ storage of​ digital camera images .​
This is​ because JPEG images can be full colour or​ grey scale, and​ are internet compatible which means that images can be sent via email to​ friends and​ family .​
The JPEG file is​ photographic specific and​ so ensures good quality.
MPEG may be seen on your digital camera and​ this stands for​ the​ Moving Pictures Expert Group which oversees video and​ audio encoding standards .​
They are responsible for​ the​ compression and​ decompression of​ video and​ audio including that of​ TV broadcast and​ digital TV networks .​
If you see MPEG on a​ digital camera, it​ means that it​ can take video clips as​ well as​ images .​
LCD is​ the​ abbreviation for​ Liquid Crystal Display and​ refers to​ the​ display screen of​ your device .​
The LCD will be full colour and​ will enable you to​ preview your picture .​
You can then use the​ LCD to​ review the​ image on your digital camera .​
The LCD is​ also where you navigate your device and​ all its features and​ settings through the​ menu button .​
The LCD panel shows all the​ relevant information for​ your digital camera whilst in​ use, such as​ battery life, and​ the​ number of​ exposures remaining.
