‘Click!’
The first image that comes to my mind when I hear ‘click’ is that of a cursor or a mouse.
But ‘Click’ can also be the sound of somebody taking a photo. If you are using a film camera, the sound comes when the film is exposed by the shutter and the next frame is advanced. In an SLR camera, the sound is generated when the mirror inside the camera rotates to direct the light on to the sensor or film. In a digital camera, the sound is generated electronically to give the ‘feel’ of taking a picture. There is usually a provision to turn OFF the sound.
FULLfx decided to name his photoblog as ‘Clickography‘ and he entrusted the logo design with me.
