Digital Photography: What's a pixel?
Forensic Engineers, Fire Investigators and Insurance Adjustors have all converted to digital photography. But what the heck is a pixel?
A pixel is a "picture element"! That's all.
Why is a pixel? Because digital electronics can only understand individual pieces of information. It constructs an image using really small pieces (pixels), which usually look like little squares on your computer screen if you can zoom in really close.
Camera resolution means how many pieces is the camera using. The more pieces, the more detail.
So, is more pixels always better? No! Why? Because there are good pixels and bad pixels. Bad pxels are those that don't show that part of the picture very accurately. So, it is better to have accurate pixels (once you have about 2 megapixels) than it is to have more pixels that are not accurate.
I will be posting some examples to make this clearer!
