Many creatives never learn the difference between vector and bitmap graphics, though understanding the benefits of each can make production choices easy. This video gives you the information you need to answer that delicate question: "Is this file vector or bitmap?" Both approaches to visual content have benefits and weaknesses, and it's likely you will use both from time to time—often in the same project.
- [Instructor] When drawing in an application…like Photoshop, you are adding pixels that have…particular color and light values.…These kinds of images are referred to…as bitmap or rasterized, which is the proper way to say…they're made of actual pixels.…If you want to edit images of this kind,…you need to edit the pixels.…There's another way though.…Vector graphics.…Vector graphics use shapes rather than individual pixels.…You can resize vector graphics as much as you like,…and they're automatically redrawn at the current resolution…of your image.…
Let's look at an example, a circle.…Here I am in Photoshop, looking at a circle…I created with the shape tool.…The tool is set to draw pixels.…Using the selection tool, I can change…the size of the shape.…Look what happens when I do.…The edge of the circle becomes jagged…because, in reality, the circle is a set of square pixels…and I just made all of those square pixels larger.…Now look what happens when I draw a circle as a shape…which is a vector graphic.…
Apart from the control handles looking a little different,…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
