Reflections
| Light Glossary |
Out-of-control reflections can hurt your image; controlled ones can enrich it. tips: keep the subject in full sun, the reflecting surface, such as water, in shade. reflections on water are most pronounced when the lens is at a low angle. most mirrors add a greenish cast to the image. normal mirrors add a "ghost reflection" to the main reflection; use a first surface mirror for critical images.

Controlled, английский
- Управляемый; регулируемый
- Управляемый
- Подконтрольный (о предприятиях)
Reflecting, английский
Pronounced, английский
A заметный, явный (син. noticeable) accent
Reflection, английский
- The abrupt change in direction of a light beam at an interface between two dissimilar media that returns the beam into the medium where it originated, i.e., a mirror
- A light ray incident on an air to glass interface will have some of its energy redirected back toward its origin due to reflection at the interface.
- The return of radiant energy (incident light) by a surface, with no change in wavelength.
- The bouncing off of light which falls upon a surface.
- The change of direction which a ray of light, sound, or radiant heat undergoes when it strikes a surface; also
- 1. the image of somebody or something which is seen in a mirror or still water 2. the process of reflecting something, especially light, sound or heat 3. careful thought 4. a situation in which an anatomical structure bends back upon itself
- The process of obtaining information about assemblies and the types defined within them, and creating, invoking, and accessing type instances at run time.
- When light bounces back from a surface
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection.2,6
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection (iesna 1984). see also diffuse reflection; specular reflection.
- The act of thinking deeply about one`s actions, behaviour`s, and progress, often facilitated by a coach or mentor to promote self-awareness and learning.

Overexposure, overexpose, английский
Overexposed images have highlights without details. causes: faulty meters, readings, or interpretations, or the conviction that if a little light is good, a lot is better. intentional, controlled overexposure, sometimes with underdevelopment, may be used to try to desaturate color or for other effects.
Dark adaptation, английский
- Optical and chemical changes in the eye which, over a period of about 20 minutes, enable people to "see in the dark." it makes exposure judgments by eye doubly difficult when light levels change. tip: at such times, color perception is minimal or non-existent.
- The reflex changes which enable the eye to continue to see in dim light. for example, the pupil becomes larger and the rods in the retina become more active than the cones.
- Process by which the retina becomes adapted to a luminance less than about 0.034 cd·m–2.2,6 in dark adaptation, the pupils dilate and the two types of photoreceptors in the retina change chemical balance. after a finite amount of time, possibly 10 min, vision will change from photopic vision to mesopic or scotopic low illumination vision.4
- Process by which the eye becomes accustomed to low luminance levels. for example, an adjustment to less than approximately 0.034 cd·m–2 for scotopic vision.19 in dark adaptation, the pupils dilate and the two types of photoreceptors in the retina change chemical balance. after a finite amount of time, possibly 10 min, vision will change from photopic vision to mesopic or scotopic low illumination vision.
- Process by which the eye becomes accustomed to low luminance levels — for example, an adjustment to less than about 0.034 cd/m2 for scotopic vision (iesna 1984). in dark adaptation, the pupils dilate and the two types of photoreceptors in the retina change chemical balance. after a finite amount of time, possibly 10 min, vision will change from photopic vision to mesopic or scotopic low illumination vision.
- Time required for the pupils to dilate and for the two types of photoreceptors in the retina to change chemical balance. after a finite amount of time, an inspector will transition from photopic vision to mesopic or scotopic low illumination vision.
