In photography, depth of field refers to how much of a three-dimensional space the camera can focus on at once. A shallow depth of field, for example, would keep the subject sharp but blur out much of ...

The iPhone’s Portrait mode uses computational photography to simulate the shallow depth of field of a digital SLR or mirrorless camera with a larger sensor. It’s evolved from a very crude tool into ...

Photoacoustic microscopy (PAM) is a relatively new imaging technique that uses laser light to induce ultrasonic vibrations in tissue. These ultrasonic vibrations, along with a computer that processes ...
