What's the difference between a raster and vector image? In this short video lesson, Chris Mattia explains the key differences you need to know to be successful in creating images for teaching and learning.
- [Instructor] You've likely heard the terms…raster and vector images.…Let's take a brief moment and talk about…what these are and why you need to know about them…for teaching and learning.…Now raster images are defined pixel by pixel.…If you zoom way in to a raster image,…using command or control plus several times,…eventually you'll get down to a grid of squares…that shows the individual blocks of color…or pixels that make up the image.…Now Photoshop is primarily a raster-based image editor.…
Which means it's primarily designed so that…you can manipulate each and every one of these…individual pixels that make up your image.…Now photographs are great examples of raster-based images…because there are lots of very fine gradations…between one region of an image and another.…And being able to precisely control the color…of each and every one of those pixels…in a wide variety of ways is what makes Photoshop…such a uniquely powerful tool.…I'll press command or control 0…to fit my image back to screen.…
