Compressed Digital Photo File Formats

The need for standard file formats Digital photos are saved as digital files on electronic media. These digital photo files are a collection of bytes.

Photons Collide against the Image Sensor Incident photons can break the covalent bonds holding electrons at atomic sites in the lattice, provided that the photon energy is sufficient.

Shoot Multiples

Two or more completely different scenes shot on one piece of film. A shot is taken, then the shutter is cocked but the film isn’t advanced.
