This video features pictures and video clips of Canalside and Erie Basin Marina. These are two of my favorite spots to visit in Buffalo. There are water activities, boat rides, food, ice cream, flowers, architecture and plenty of activities for everyone. There are plenty of family friendly games and events as well. Go check out my video and thanks for stopping by.
This video is filled with my photos of Niagara Falls, Ny. This is one of the wonders of the world and I never tire of seeing the majestic beauty of the falls. It truly is amazing. Please watch my video on youtube and thank you for stopping by.
A new video is waiting to be explored on my youtube channel, Coffeebeanz. This is a series of photos taken of Buffalo, NY. It is a small sample of what this great city offers. Buffalo is going through a resurgence and I am enjoying capturing all of this history in the making. Please go watch my video and thanks for stopping by
Please take a few moments and check out my new video on youtube. Thank you for stopping by.
Please go check out my new video. It features photos I have taken of architecture and building designs. I really enjoy unique structures of both modern and older styles. This video has some interesting designs in it. Thanks for stopping by.
This is a new and improved version of the previous video I posted. This version has more pictures too. Please check it out. Thank you for stopping by.
Please check out a short video I made for my youtube channel. It is a sample of pics I took. The link is below.
Two of my favorite phot editing apps are Instagram and Photo Editor by Aviary. I love all the filters they provide. They are available on IPhone and Android. You can turn dull pics into awesome pics. You can turn good pics into better pics. You can make pics look funky and wild, even futuristic with filters. There are endless possibilities. It’s a must have.
In digital imaging, a pixel, or pel, (picture element) is a physical point in a raster image, or the smallest addressable element in a display device; so it is the smallest controllable element of a picture represented on the screen. The address of a pixel corresponds to its physical coordinates. LCD pixels are manufactured in a two-dimensional grid, and are often represented using dots or squares, but CRT pixels correspond to their timing mechanisms and sweep rates.
Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color image systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black.
In some contexts (such as descriptions of camera sensors), the term pixel is used to refer to a single scalar element of a multi-component representation (more precisely called a photosite in the camera sensor context, although the neologism sensel is sometimes used to describe the elements of a digital camera’s sensor), while in others the term may refer to the entire set of such component intensities for a spatial position. In color systems that use chroma subsampling, the multi-component concept of a pixel can become difficult to apply, since the intensity measures for the different color components correspond to different spatial areas in such a representation.
The word pixel is based on a contraction of pix (“pictures”) and el (for “element”); similar formations with el for “element” include the words voxel and texel.
Resolution of computer monitors
Computers can use pixels to display an image, often an abstract image that represents a GUI. The resolution of this image is called the display resolution and is determined by the video card of the computer. LCD monitors also use pixels to display an image, and have a native resolution. Each pixel is made up of triads, with the number of these triads determining the native resolution. On some CRT monitors, the beam sweep rate may be fixed, resulting in a fixed native resolution. Most CRT monitors do not have a fixed beam sweep rate, meaning they do not have a native resolution at all – instead they have a set of resolutions that are equally well supported. To produce the sharpest images possible on an LCD, the user must ensure the display resolution of the computer matches the native resolution of the monitor.
Resolution of telescopes
The pixel scale used in Astronomy is the angular distance between two objects on the sky that fall one pixel apart on the detector (CCD or Infrared Chip). The scale s measured in radians is the ratio of the pixel spacing p and focal length f of the preceding optics, s=p/f. (The focal length is the product of the focal ratio by the diameter of the associated lens or mirror.) Because p is usually expressed in units of arcseconds per pixel, because 1 radian equals 180/3.14159*3600=206,264 arcseconds, and because diameters are often given in millimeters and pixel sizes in micrometers which yields another factor of 1,000, the formula is often quoted as s=206p/f.
Digital photography uses an array of electronic photodetectors to capture the image focused by the lens, as opposed to an exposure on photographic film. The captured image is then digitzed and stored as a computer file ready for digital processing, viewing, digital publishing or printing.
Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.
Digital photography is one of several forms of digital imaging. Digital images are also created by non-photographic equipment such as computer tomography scanners and radio telescopes. Digital images can also be made by scanning other photographic images.
