The Meanig of Photograpy

In my opinion, must be returned to the true meaning of photography itself ....
From some literature that I can, the definition of photography is painting with light.

If the ultrasound itself is very different once the principle works, because ultrasound alone for short is the Ultra Sono Graphy. The principle works using Ultrasonic waves generated by a given crystal electric waves.
Ultrasonic waves are sound waves beyond the limit of human hearing that is above 20 kHz or 20,000 Hz or 20,000 vibrations per second.
Its crystals can be made ​​of various kinds, one of which is Quartz. The nature of these crystals, will provide vibration when given electric wave.

Ultrasonic equipment itself there are various types. There Scan Type A, B and C.
What used to detect the crack in the steel is type A.
The principle works very easily. Living uses ultrasonic sensors to menngirimkan ultrasonic wave and catch it again. Incidentally, I make this tool when making thesis.

What type C to display the image of 3 dimensions by means catch the reflection-reflection which is different from the thickness of thin objects in a liquid. Since there are various kinds of ultrasonic waves reflected at different times, these waves are then translated by the processor to be converted into images.

So an ultrasound display image of the captured sound, while the notion of photography is painting with light.

So maybe for now the results of ultrasound has not been included in the photographic work. In contrast to the scanner and pinhole camera that is still "painting with light".
