Mechanic Working of Digital Camera
Process appear of picture on film start from light pass lens to shutter and contact with film plate. After that when film contact with light its changed chemical become picture for mechanic picture creating of digital camera is likely but different at digital camera use digital process is related when push shutter button electric current is sent to sensor light pass lens contact with each pixel on sensor. When each pixel receives light each pixel will change light data to number digital data. This data is sent to compile become picture file at compile unit. This compiling don't use more time for zip file, size adjusting, color adjusting, clearness and picture that receive is taken to display on LCD monitor and recorded into memory card too.
Note: What is shutter Lag?
Shutter Lag is the delay of process after taking picture.
