What purpose do Reflectors serve in Photography?

A Reflector refers distinctly to an equipment used by photographers and cinematographers to bounce light in a certain direction. It acts as a medium to bounce light and redirect light to illuminate the subject more effectively! A reflector can be either artificial or natural, natural reflectors are objects in the environment that naturally reflect light - cars, walls, buildings, roads and other reflective surfaces are natural reflectors.



Artificial reflectors are used by photographers to control the brightness and intensity of available light and to counteract harsh over exposure due to available light. The artificial reflector is made up of two parts, the reflective material and the frame. The purpose of the frame is to keep the reflective material taught at an angle that directs the reflected light to a specific direction. 


There are many different reflective surfaces used, the most common being, white, silver and gold. Depending on the specific reflective material used, a different effect is achieved by varying the distance from the subject and angle of reflected light. Black colored reflectors are used to absorb light and introduce shadows.


Reflectors empower the photographer to control the quality of light and also gives them control over the overall contrast and shadows created by reflecting natural or artificial light from a light source. An additional use of reflectors is when it is coupled with a studio strobe. it varies the angle at which the light is emitted out. Reflectors vary in size and shape and depending on the particular need of the photographer or cinematographer to light a scene, a particular type of reflector is used.

Why is there a groove line on the "F" and "J" keys on keyboards?

The bumps or nipples found on the F and J keys on the keyboard helps users correctly position their left and right hand on the keyboard without having to look at the keyboard. For example, without looking at your keyboard you should be able to feel the keyboard and correctly position your left index finger on the F and the right index finger on the J. From this position, you should be able to locate the remainder of the keys on the keyboard. A phone having a hardware numeric keypad has something similar. The digit 5 also has a bump. It is also used for the same purpose. One can easily and quickly enter the digits without having a look at the keypad.

What is TrichoScan?

Quantitative methods for the analysis of human hair growth and hair loss are necessary for patient follow-ups or to determine the efficacy of hair growth promoting drugs.  While reviewing the capabilities of the different methods, the common theme emerges that most techniques are of little practical use to the clinician because they are time consuming, costly, or difficult to perform. An operator- and patient-friendly, inexpensive, validated, and reliable method for assessing hair growth was therefore a rational need.  With TrichoScan, such a tool is now available. TrichoScan is a software-based method for the analysis of human hair. For this purpose, digital images are taken from the scalp with a specially developed camera-optics system. TrichoScan software is then used to automatically calculate important parameters of hair growth, such as hair density or thickness from the images.
