Hyperlapse or moving time-lapse (also stop-motion time-lapse, walklapse, spacelapse) is a technique in time-lapse photography for creating motion shots. In its simplest form, a hyperlapse is achieved by moving the camera a short distance between each shot. The first film using the hyperlapse technique dates to 1995.
In time-lapse photography, the camera records images at a specific slow interval such as one frame every thirty seconds (1 ⁄ 30 fps). The shutter will be open for some portion of that time. In short exposure time-lapse the film is exposed to light for a normal exposure time over an abnormal frame interval.
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
The app enables users to record videos up to 45 minutes of footage in a single take, which can be subsequently accelerated to create a hyperlapse cinematographic effect. [7] Whereas time-lapses are normally produced by stitching together stills from traditional cameras , the app uses an image stabilization algorithm that steadies the appearance ...
As the other biochromatic chromatophores are also capable of pigment translocation, animals with multiple chromatophore types can generate a spectacular array of skin colours by making good use of the divisional effect.

It is a tool similar to a camera to allow for inspection of skin lesions unobstructed by skin surface reflections. The dermatoscope consists of a magnifier, a light source (polarized or non-polarized), a transparent plate and sometimes a liquid medium between the instrument and the skin. The dermatoscope is often handheld, although there are ...
The skin weighs an average of 4 kg (8.8 lb), covers an area of about 2 m 2 (22 sq ft), and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are glabrous skin, the nonhairy skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [16]
The skin of the face is thicker than the skin overlying the lips where blood vessels are closer to the surface. As a consequence, the margin of the lips shows a transition between the thicker and thinner skin, represented by the vermilion border. It therefore has the appearance of a sharp line between the coloured edge of the lip and adjoining ...
