Visible spectrum
The electromagnetic spectrum of visible light; red, orange, yellow, green, blue, indigo, violet.
Warm colours
Are any colour which, by association suggest warmth, such as red, orange and yellow.
This is the spectrum of shades of gray and black and white of an image.
Gyro Stabilization System
This equipment is often found in airplanes and helicopters to which you attach your camera to keep it steady while shooting aerial photography.
The Visible spectrum consists of billions of colors, a monitor can display millions, a high quality printer is only capable of producing thousands, and older computer systems may be limited to 216 cross-platform colors.
The Color Spectrum
Both the natural light of the sun and artificial incandescent light appear white to the naked eye. However, if you shine light through a prism, it splits into a rainbow of colors.
-White light spectrum is the electromagnetic wavelengths between 400-700 nanometers. Also referred to as the visible spectrum.
Overlaying the spectrum on the spectral curve (see Figure 6) helps to illustrate the information contained in the curve.
ELECTROMAGNETIC SPECTRUM - The entire range of electromagnetic radiation - all of its wavelengths, including those of visible light.
The visible light spectrum lies between 380 nm (violet) and 760 NM (red).
Light travels at a constant velocity of 300.000 km/s; it takes 1,25 sec to the moon, and nearly 8 minutes to the sun.
Lightness ...
Gray scale: The spectrum, or range, of shades of black an image has. Scanners' and terminals' gray scales are determined by the number of gray shades, or steps, they can recognize and reproduce.
Like monitors, printing inks also produce a colour gamut that is only a subset of the visible spectrum, although the range is not the same for both.
Electromagnetic Spectrum The distribution of light separated in order of some varying characteristic such as wavelength or frequency. The "electromagnetic spectrum" refers to the full range of possible frequencies and wavelengths of light.
ELECTROMAGNETIC SPECTRUM-The entire range of wavelengths, extending from the shortest to the longest or conversely, that can be generated physically.
Achromat: A lens that is able to bring two primary colors of the spectrum to the same point of focus.
Acid fixer: A chemical used to neutralize alkali. It is used in the final stage of processing to stop the action of alkaline bath.
Well, color is that part of the electromagnetic spectrum that human vision can see. But there are three elements to consider and understand. First, the light source.
Most of them have a second area of sensitivity outside the spectrum of visible light.
Extra-Low Dispersion Glass All photographs are made with light, composed of many colors of the spectrum.
Colour spaces describe how the red, green and blue primaries are mixed to form a given hue in the colour spectrum.
Our eyes are most sensitive to green which lies in the middle of the rainbow and less so to the colors towards the ends of the spectrum.
On the other end of the spectrum, there are situations in which you will want the greatest depth of field available. Any type of subject that requires sharp detail throughout would fall into this category, such as landscapes or cityscapes.
There are three types of cones, which separately sense three different portions of the spectrum, Red, Green and Blue. Our perception of which color we are seeing is determined by which combinations of sensors are excited and by how much.
The "traditional" visible spectrum runs from red to violet. Red light has the longest wavelength and violet the shortest.
The image sensor that separates the spectrum of color into red, green and blue for digital processing by the camera. [In digital cameras both Area and Linear CCDs are used. A CCD captures only black-and-white images.
1) They do not have a continuous spectrum, if you look at the spectrum of a standard light bulb or of the sun the spectrum is a very smooth color gradation from red to blue, as I mentioned above.
Experience can do the most for any outlook that fits photography into the spectrum of artistic understanding, all that is required is a camera and a little know-how on most accounts, ...
This illustration represents all of the color in the visible light spectrum, or those colors to which the human eye is sensitive. Within the visible light spectrum resides the parameters, or gamut, of different color spaces.
Many digital desktop setups contain a continuous spectrum of tones, ranging from pure black at one end to pure white at the other. This continuous scale can be thought of as dividing into a series of individual tones called a gray scale.
This covers a visible light spectrum and not the entire light spectrum. An easy way to remember the progression of light colors is the acronym "Roy G Biv". This stands for "red, orange, yellow, green, blue, indigo, violet.
When post processing the image, the added color information of the RAW file allows for expansion of specific parts of the color spectrum for correcting of less than perfect exposures.
Nikon manufacturing covers a broad spectrum of production requirements from small-lot, multi-type production demanding high reliability to volume production, where quality control is crucial.
So if you're trying to take a photo under, say, a mercury arc light with its weird spectrum of light output, you can't do much to alter the colour balance of the photo by using a filter.
The visible light spectrum is scientifically described in terms of color temperature, and is measured in degrees Kelvin (K).
IR Infra Red Light is a frequency of light which is lower than the human eye's visible spectrum (in the range of 850 ~ 950 nanometers). Color cameras CANNOT use infrared light whatsoever.
A part of the electromagnetic spectrum from about 400nm down to 1nm. It is invisible to the human eye, but most photographic materials are sensitive to near UV bands down to 250nm.
Usually, the visible spectrum is hidden unless refracted by prism or a rainbow (simply many thousands of water droplets acting as prisms).
By repeating the experiment with different reference colors chosen form the visible spectrum it was possible to come up with mathematical descriptions of all the colors of the spectrum based on the relative amounts of R, ...
As much as I love to capture subjects with saturated color because of the powerful visual impact they offer, I also seek out the opposite end of the spectrum. Subtle and desaturated colors create impact in a very different way.
As a rough rule, high pH favors the red end of the spectrum and low pH favors the blue end of the spectrum. A simple way to increase the pH is to add S2 activator. (Usually adding 10- 50 mL to a tray of developer will have a significant effect.
For example, normal incandescent interior lighting is heavily weighted towards the orange-red end of the spectrum, and fluorescent light has a green cast.
A Band of wavelengths within the electromagnetic spectrum invisible to the human eye which are shorter than the blue end of the spectrum. All films are sensitive to some ultraviolet radiation.
many personalised photo gifts which can now be designed, ordered and produced by absolutely anyone who owns a digital camera, with a choice which ranges from the small and relatively inexpensive to more lavish gifts at the luxury end of the spectrum.
The B/W Conversion filter utilizes a Spectrum slider that allows you to target a particular color range and manipulate how it's rendered. The B/W Conversion: Dynamic Contrast filter includes a Contrast Enhancer slider that's used as the name implies.
Many zooms will have different maximum apertures at different points along the focal length spectrum. For example if it's an 18-55mm kit lens it will have a maximum aperture of f3.5 at 18mm and a maximum aperture of f5.6 at 55mm.
Ultraviolet (UV) is light along the color spectrum that is beyond the visible blues. UV light has short (high energy) wavelengths, as opposed to infra-red (IR) light which has long wavelengths, and is also invisible to the human eye.
They fall into spectrums that can soothe the mind or create movement and calamity. The strategic use of color is critical to the mood, feeling and impact of the image. It can be just a part of the composition or make up the entire photograph.
On the other end of that spectrum, some people are careless about their digital cameras. They don't think anything of leaving their cameras in stuffy car when the temperature outside is 100 degrees. All cameras hate extreme heat and extreme cold.
Describes the whole range of colours in the spectrum.
ICC Profile
The International Color Consortium describes rules on colour management. Printers, cameras etc.
Beyond violet. That part of the electromagnetic spectrum which lies beyond the violet end of the visible spectrum, i.e. of shorter wavelength than violet, and invisible to humans.
USM
Unsharp Mask. A process used to sharpen images ...
It is named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet. UV light is emitted by electric arcs and specialized lights such as black lights.
The DP1's 'sharpness spectrum' is quite limited and even at the highest sharpness setting the camera's JPEG output does not look oversharpened.
