Dot - A unit used to represent the smallest element a printer can image, but sometimes used to represent the resolution of other devices, such as monitors or scanners.
dot pitch
The measure of the spacing between the centers of physical pixels on an output device, usually a monitor. On monitors, dot pitch is expressed in millimeters (mm) between the centers of like-colored pixels. See shadow mask.
dot gain
dpi
Dots per inch, a measure of the spatial resolution of a digital image or a capture device. See also ppi and spi.
DOT

Dot Gain: An increase in the size of halftone dots that may occur as a result of errors or imperfections in any of the steps between screening an image and printing it onto paper.
Dot, Target
Round devices used to shadow areas of the scene to control Contrast or improve lighting.
Double Exposure
The re-exposing of film, intentionally or not, to a second image.
Dot
The smallest raster element of an image. Many dots together produce one pixel. Meaning, for example, that in the specification "8 bit depth", three "layers" of 256 dots each are on top of one another to produce one pixel.
Dot pitch is measured in millimeters (mm), and a smaller number means a sharper image. How you measure the dot pitch depends on the technology used.

'Black dot' filters can also be bought for a similar effect but aren't as easily portable.
For an even further amount of diffusion, rubber band the material around the lens. Because it is further away from the lens, it will soften it even more.

The "white dot" ambient light sensor that the D2x and D2Xs had is missing from the D3. It seems that this was an idea that just didn't provide enough added benefit to justify continuing with.
I've put a dot on my knob, so it's easier to see how far I've turned it.
Pixel - A single dot within a digital photograph. The typical photograph is made up of thousands of pixels.
Pixel
A small dot in a digital photography image. Thousands of pixels make up a digital photograph.
Picture element: a dot or a small area of a picture that carries the three attributes: hue, color saturation, and brightness. Any picture can be made up of an array of dots with these attributes, viewed from a distance that the dots are not visible.
Dot pitch Describes the distance between the perforations on the monitor's shadow mask- The better displays usually have a dot pitch under 0.28mm. As with fine halftone screens, the smaller the dots, the sharper the image.
A striking 3 inch LCD with 921,000 dot resolution is perfect for detailed image or movie capture and review using the Live View function.
4 million dot OLED electronic viewfinder. The big question is - is this as good as a optical viewfinder? Probably not, but the verdict so far is that it is fairly close, and better than any other viewfinder out there.
An operator's dot is often placed on the slide mount to aid in organizing the slides in the tray.
Camera focus when shutter release button is half pressed and locks when the in-focus indicator (a solid dot) appears on the viewfinder status LCD.
This might only enlarge the moon from a tiny dot to a small dot… nothing to write home about.
Take the photo on days when the moon is “large'.
The "green dot" that guides the focus really does not work that well. I have "focused" the lens up and down a fair amount and the green dot stay lit. Thus using the green dot to focus is rather inexact.
Note that most output devices, including dot-matrix printers, laser printers, and display monitors, are raster devices (plotters are the notable exception).
Why Go Now: The T-Dot has never been easier to reach. Classy Porter Airlines increased daily service from Boston, Chicago, Myrtle Beach, and Newark in 2010; wifi-friendly Virgin America added direct flights from Los Angeles and San Francisco; ...
Of course, this assumes output from a photo quality printer which has a decent dot layering process.
You'll notice that there is usually a red dot on the distance scale window as well. This is used for determining the focus distance when using infrared film with an infrared filter.
The focus mark may be a small dot or line near the feet and meter distance markings on the barrel of the lens. When you look through the viewfinder, it will look as if it’s out of focus. Ignore this fact and take the picture.
A dye-sub printer can print a dot of ink for each pixel that has the same color and tone as the pixel in the image. In essence, a dot can be any one of 16 million colors. If the pixel is a light red, the printer prints a light red dot.
Precise rendering of detail, invisible dot structure, smooth gradations, subtle separation of closely matched tones, open shadows, full highlights, bright whites, rich blacks, and the reintroduction of hue (typically, ...
Now, we focus our lens on the middle dot, which comes out in perfect focus.
This technology allows the dot intensity to vary and to create many more colours than thermal wax. The dye are vaporized at the high heat and diffused across a small gap to the paper or transparency.
Make time for Rhode Island photography of the many magnificent mansions and estates that dot the shore of Easton Bay on the Newport peninsula.
In cameras, a pixel is a tiny dot that makes up part of an image, and a megapixel is a collection of a million of those pixels. When you're talking about 6MP, you're referring to six million pixels.
The main disadvantage to using an EF-S lens is that they are only compatible with Canon EOS cameras that contain both a red dot and a white square on the lens mount. The red dot means the camera supports EF-S lenses.
Tip: Make sure the cursor dot is on the thick horizontal or vertical lines.
A pixel is a tiny square on a computerized display that is so small it appears as a dot. The display screen is a solid grid of these squares or dots, which can be easily seen with a magnifying glass.
The image size of the sun, however, may be a mere dot on the negative. In the NYI Text Camera and Lens is a Chart that shows that a 50mm normal lens has an angle-of-view of 43-degrees.
Pixel is short for Picture Element, and it's basically a dot. All digital pictures are made up of these dots, and counting them is a measure of the image (pixels per inch, or PPI), print (dots per inch, or DPI), ...
This can be accomplished by aligning the index dot on the lens with the index dot on the camera and rotating it counter-clockwise until you hear an audible click.
When you oversharpen you will often see a strange grainy dot pattern somewhere in the image. It is better to run the Unsharp Mask twice for half of the total amount of sharpening than just once. Running it twice results in a smoother sharpening.
printing a photo, remember that your DPI setting on your printer must be set substantially higher than your PPI setting: while computers can produce multiple colors within a given pixel, your printer can only print a single color within a given dot.
Pixel - "Picture Element" - the smallest dot of a picture. In color photographs, consists of three smaller dots (or stripes) one each of red, green and blue.
If you think back, how often have you seen images with the main subject as a small dot to far away or an image with the subject placed in middle of the frame. Did these images give you a wow experience? Probably they did not.
(PICture ELement) The smallest element of a digitised image. One small dot of light among the many dots that make up an image on a computer screen.
Megapixel ...
It continues to use the 18MP CMOS sensor seen in the Rebel T2i (550D) but gains a tilt and swivel 1,040k dot LCD monitor like the one offered on the more expensive 60D.
Acceptable Circle of Confusion - the size of the largest circle which the eye cannot distinguish from a dot. In 35mm format cameras, a 0.03mm diameter circle of confusion is considered acceptable.
The "Auto-Exposure Bracketing" button as shown below the green dot in the picture to the right, allows you to shoot your images at a selected over or under exposure value (+/- EV).

A pixel-by-pixel representation of an image where each bit is mapped to a corresponding pixel or dot. Also commonly referred to as a raster image because the pixels are laid out in a rectangular grid or array.

Shooting the moon with a 50mm lens will produce an image that looks like a dot. You'll be a little better at 200mm, but a 500mm lens will do a good job. If you have a small telescope, you can make a close-up photo of the moon with great detail.
