   Facts of The History of Photography.

 

  - The meaning of the word "Photography" has been attributed in 1839 to Sir John Herschel based on the Greek φῶς (phos) meaning "light" and γραφή (graphê), meaning "drawing, writing", together meaning "drawing with light" 

   

- The first color photograph was a set of three photographs taken through red, green and blue color filters and shown placed or lay  over another, by using three projectors with similar filters.

 

- Photographing, the images formed in a small camera, the photographs came out as negatives, the darkest parts where the camera image was the lightest and vice versa.

 

- The oldest surviving permanent photograph of the image formed in a camera was created by Niépce in 1826 or 1827.[1]

  - Pin hole camaras have a peice of paper with a coating of silver iodide was exposed in the camera and developed into a translucentnegative image.  The negative could be used to make a large number of positive prints by simple contact printing.

 

  - When using cameras, ther are different parts that play an important roll for forming a perfect picture.

 

  - We have the lens, which bends the light into the camera.

 

  - Finally, we have the focus, which in order to keep the image of a close object sharp, the lens must be moved relative to the  camera sensor.

 

  - This process is called focusing. Then we have the Exposure Triangle, which includes 

 

ISO – the measure of a digital camera  sensor’s sensitivity to light.

Aperture – the size of the opening in the lens    when a picture is taken.

Shutter Speed – the amount of time that the shutter is open.
