1. Image resolution is measured in pixels per inch (PPI) and determines image quality, with more pixels resulting in higher quality. 2. There are two factors that determine the total number of pixels in an image: its size in inches and its resolution in pixels per inch. 3. Common resolutions include 256x256 for low quality images, 640x480 for basic web images, 2240x1680 for 4 megapixel cameras, and 4064x2704 for high-end 11 megapixel cameras.

2. Resolution
• Bitmap images are made up of pixels. Image resolution is the number of
pixels per inch (PPI) in the bitmap grid the more the pixels the better
quality image is
• There are two features to every bitmap image – its size meaning the width
and height In inches and resolution meaning the number of pixels per
inch.
• Both of these factors both determine the total number of pixels in a
picture

3. resolution
• Some typical resolutions include:
• 256x256 – found in many cheap cameras, this resolution makes the camera picture
quality really bad almost unacceptable. This resolution holds 65,536 individual
pixels.
• 640x480 – this is found in low end cameras, but mainly this resolution is used for
sending pictures or posting pictures on a website. This is has 307,200 pixels or 0.3
mega pixels*
• 2240x1680 – this resolution is mainly found in 4 megapixel cameras (the current
standard) this allows even bigger printed photos, with good quality for prints up to
16x20 inches. This resolution holds over 3 million pixels.
• The top end cameras mainly use 4064x2704, this is a basic digital camera with 11.1
megapixels which takes a picture at this resolution, plus when you print a picture
you can create a 13.5x9 inch print with no picture quality.
• *megapixels – more than 1 million pixels

4. resolution
• The more the pixels there are within a picture, the more
detailed the image can be displayed at.
• But the fewer pixels there are in an image, the less
detailed the image will be displayed at.
• There are two ways to show an image mainly on screen
and print:
• The standard for screen displays is 72 PPI.
• The standard for Print is 300 PPI.

5. pixels
• In digital imaging, a pixel is the physical point In a raster
image. So it is the smallest element of picture represented on
the screen. The address of a pixel resembles to its physical
co-ordinates.
• The term pixel is in fact short for Picture Element. These small
little dots are what make up the images on digital. The screen
is separated up into a matrix of thousands or even millions of
pixels.
