IMAGE RESOLUTION
Cut out and glue this example image into your notes - provided by Mr. Brown
Digital Images are made of small squares of color called pixels.
Dimensions are expressed in the total number of pixels along the width and height of an image.
Resolution is the number of image pixels assigned to each inch when an image is printed - measured in pixels per inch (ppi). Thus, the more pixels an image has per inch, the greater its resolution will be. And, a high-resolution image will produce a better quality printed output.
Put into some very basic terms, resolution is the quality of the image. As the resolution goes up, the image becomes more clear, it becomes sharper, more defined, and more detailed as well. This is because there’s more information in the same small space.
Image Resolution:
Think of resolution as “image quality”
Raster or “photo” files are made of pixels- tiny tiny squares
the more pixels the sharper your image and the larger the file.
PPI=pixels per inch
300 ppi for PRINT!
72 ppi for web, computer monitors, etc
But wait!!! READ THIS!!!
I haven’t changed the resolution, but my images are still blurry, what’s wrong?
Nothing is wrong with the resolution settings on your camera or your computer monitor, but there are a number of other things that can go wrong in the course of a photo shoot.
File types:
After the dot(.) means the type of file it is
Examples:
.psd is a photoshop file
.doc is a word document
.pdf is an acrobat document
.jpeg is a generic picture file
.png (web picture image)

- You may have shaken the camera too much while taking the picture at a slow shutter speed, or
- You could have focused on the wrong part of the scene.
