Digital like analog???

[DigitalPalsecam]

An analogue camera uses film but a digital camera does not.
This area, equivalent to the eye's retina, is replaced by a silicon chip known as a Charged Coupled Device( CCD). Light enters via the lens and falls on to many tiny pixel elements etched on to the chip. Light is turned in to a tiny amount of electrical charge and each cell's content is sequentially moved across the chip like a line of buckets handed from one person to another until it reaches the edge of the chip. This 'Bucket Brigade Device' then stores the [pixel elements in the memory card for printing out.

Which had NOTHING to do with the question.

I wonder if the OP even cares since this tread is FIVE years old.
