Photoshop CS5 for Photographers provides comprehensive Photoshop training targeting the needs of photographers. In this course, author Chris Orwig demonstrates the fundamental skills used to enhance digital photos, including managing and correcting color, sharpening, making selections and adjustments, retouching, and printing from Photoshop. In addition to teaching the techniques that enable photographers to refine and publish their photos, the course includes live-action segments that encourage thinking photographically and shooting with Photoshop’s capabilities in mind. Exercise files are included with the course.
Our next step is to really get a hand on how we can size and resize our photographs inside of Photoshop. Yeah, before we do that, we have to dig into this topic of image size, because I can't tell you how many students that I have had that do all this work in Photoshop, yet from the get-go, they resize their image incorrectly. So, all their Photoshop work really isn't worth much at all. So, image size really is one of those foundational or key concepts inside of Photoshop. So, sometimes it's helpful to talk about it by way of an analogy.
Now, here's the best analogy that I've come up with. My wife is a teacher. She teaches elementary school. Every once in awhile I visit her classroom, and it's a ton of fun. In one visit, they were working on this art project where they had these kidney beans. What they would do is they would take these beans and glue them to a paper plate in order to create a design. As I walked away from the classroom, I thought, ah! That's a perfect analogy for how image size works inside of Photoshop. Let me explain. Let's say we go to the teacher and we say, Mrs. Orwig, I need some kidney beans.
So, we then capture or collect our information. In this case, we have seven kidney beans. We walk back to our desk and we resolve to create a design on a large paper plate. Well, once we do that we realize this doesn't really work. There are gaps between those kidney beans. So, we go back to the teacher. We say, hey! Mrs. Orwig, do you have some more kidney beans? She says, of course. So, we collect or capture the data. Then we go back to our desk, and we resolve to put these kidney beans on a smaller paper plate.
In this case, the image looks much better. All right, well, you may be wondering, okay, look I am kind of on tracking with you, but, how does this completely connect to Photoshop? Well, it connects on a couple of levels. For starters, when we are capturing information, typically, the more information we have, the more flexibility we'll have and many times the better results. For example, like with my niece Evie here. You can see that she created this amazing turkey by gluing all these little pieces to this paper plate. In more particular terms, in regards to Photoshop, we have this dialog called the Image Size dialog.
In a first glance, this may seem a little strange or a little foreign. So, what I want to do is break this down for size. Up top, we have what are called the Pixel Dimensions. You can think of this as the raw or tangible data. This is how many kidney beans we have in our hand. This is how much stuff we have to work with. Then next underneath that we have our Document Size. This has to do with the actual dimensions of that paper plate, right, or how we are resolving to use something in the distribution of the information that we have.
So again, Pixel Dimensions up top have to do with the actual information. Then the Document Size down below has to do with our paper plate and also resolution, how close we are going to put some of this information together. Now, while this analogy is in no way perfect, what I hope is that it begins to demystify the Image Size dialog box a little bit. Now, that have been said, I realize that at this point this topic is still kind of theoretical and a little bit abstract.
So, what we need to do now is actually take a look at how we can start to resize our images, and we are going to do that in the next few movies.
