Editing Canvas Sizes in Photoshop

Video Transcript

" My name is Dan Kallenberger. I am an instructor at a technical college teaching Visual Communications and Photoshop as well as other Adobe products. I’m going to be showing you Photoshop CS2 today. When you open an image inside of Photoshop, the first thing I like to do is find out what the size is of the image. The fastest way to do it is to click on the blue bar or the bar along the top of your image and you right click on that. You can find image size and canvas size. What is the difference between image size and canvas size? Image size allows you to enlarge the whole image. Canvas size allows you to increase your canvas area. So if you wanted to paint around the lilies you would do canvas size. If you wanted to change the size of this..Let’s say we need to make this an 8 ½ x 11 printout on a printer. You would do 300 pixels per inch, we would change this to width of 10 inches and I’m actually going to go with 8 inches and then crop it later. I’ll show you canvas size. So I’m creating this image from this lily image to an 8x10. So if you wanted to take a photo graph you took of your kids, what you can do is just change the resolution so it’s a better quality. Hit okay and now you’ve changed the image size. If you need to change the canvas size or you need more room around the lilies, you would right click and do canvas size and actually make this larger at 20 inches say by 36. Let’s do 24x36. So say we needed a poster but we wanted to add text around it. This adds canvas size around your image so then what you can do is add things to it. This is canvas versus image size. "
