1.5 inch=300 pixel
Resulation means pixel per inch either row side or column side, so row side= 512/2=256 or column side 512/2=256.
It is the same. 1 dot is also 1 pixel.
For a 12 x 12 inch print your ideal image resolution dimensions should be 3600 pixels by 3600 pixels. At a minimum your dimensions should be 1800 by 1800 pixels. Larger mega pixel producing cameras are often better when you want to crop your image down to smaller sizes.
It depends upon the physical resolution of the display unit and its manufacture. There can be between about 70 pixels per inch and 325 pixels per inch. (or each pixel is between approx 0.014 in and 0.0031 in wide) - from this the limitations of the resolution than can be displayed is derived. For example, I have an 19 in CRT monitor which can physically display 1600 px by 1200 px over an area of approx 14.4 in by 10.8 in; which means that there are 111 pixels per inch, making each physical pixel approx 0.009 in. Other resolutions of output (1280x1024, 1024x768, 800x600, 640x480) are achieved by overscanning the pixels, sometimes using more than 1 physical pixel to display the pixel (eg 800x600 is achieved by displaying 4 pixels for each pixel (a 2x2 grid) of the output, making the pixels approx 0.018 in in this case, or approx 56 px/in). My laptop display is approx 13 in by 8¼ in with a physical resolution of 1280x800 which gives 96 px/in and thus each pixel is approx 0.0104 in (as given by Lifesnadir above). Again, other resolutions are achieved by over scanning pixels. Another 17 in CRT monitor I have has a dot pitch of 0.28mm which gives approx 91 px/in or each pixel is 0.011 in for its native resolution of 1280×1024.
A pixel is the smallest area in a digital image. It does not have a unique size, it depends on the amount of detail specified for that image.
The size of the image is 2.67 inches x 2.83 inches (width x height) when printed at 240 pixels per inch.
If the image is 800 pixels by 600 pixels at 240 pixels per inch, then the image size is (800 / 240) by (600 / 240) or 31/3 by 21/2 inches.
1.5 inch=300 pixel
Intensity is the amount of light the pixel reproduces (how bright it is). Density refers to the amount of pixels that are used to encode an inch or an centimeter of the photograph.
bitmap or raster images are in other words pixel images and every pixel image must have resolution, resolution is number of pixels per inch, cm
Technical characteristics:- number of colors (how many bits per pixel are supported)- image size (width x height in pixels - also call image resolution horizontal, respectively vertical)- file size (size in bytes of the file where the image is saved)- display/print resolution, usually in dots per inch/cm (a description on how to output the image)Subjective impressions (for example when evaluating photographs)- subject of the image- background- type of the composition (surreal, landscape...)A pixel is a single rectangular element of an image. A pixel has a defined color.
Changing resolution you will change print size of photo or both print size and pixel dimensions. This depend what resolution you need. Example: if you have 400x200 px image with 300 resolution (1.3 inch wide printable dimension) changing resolution to 72 px per inch you can get 1600x800px image with 5.2 inch wide printable dimension.
Photoshop is an image editing program. Resolution is the term used for how dense an image is pertaining pixels. Photoshop can handle any range of resolution as long as the computer has enough speed and enough RAM (Random Access Memory) to handle large resolution images. Within Photoshop, resolution refers to pixels per a measure of length. In the US, it is usually measure as pixels/inch. In Europe, pixels/centimeter. A pixel is the smallest "part" of an image, so higher the pixel/inch gives the image more detail and "crispness."
It depends how big the pixels are.
Depend on image resolution. You can see image resolution in Photoshop from Image > Image Size. Pixels are just the tiny dots that form images, they are not a form of distance measurement. To demostrate this, take for example a 40 in. TV. That 40 inch TV might contain 1920 x 1080 pixels to make up the screen, but likewise, a computer screen that is only 20 in. can also have the same amount of pixels.
To transmit an 8 by 10 inch image over an ISDN B channel with 300 pixels per inch and 4 bits per pixel, calculate the total number of pixels in the image: 8 (inches) * 300 (pixels/inch) * 10 (inches) * 300 (pixels/inch) = 7,200,000 pixels. With 4 bits per pixel, the total number of bits required would be 7,200,000 * 4 = 28,800,000 bits. Convert this to bytes by dividing by 8, giving us 3,600,000 bytes or approximately 3.43 MB for transmission.
