In Photoshop CS6 for Photographers, author, photographer, and teacher Chris Orwig explores Photoshop from the perspective of the photographer.
The course details the features and techniques behind enhancing and retouching photos, preparing them for print and online publishing, and much more. Chris demonstrates how to make basic edits in Camera Raw, develop and save color profiles, work with layers and selections, tone and sharpen, and retouch images while retaining their natural character.
Chris also shares some creative tips and project ideas, such as converting a photo to black-and-white and enhancing a portrait with hand-painted masks. The course also covers workflow details, such as organizing images in Bridge and Mini Bridge, optimizing Photoshop preferences, and calibrating your monitor.
Now that we've been introduced to the topics of pixels and bit depth and also the image size dialog, let's take a look at how we can resize a photograph. We'll be working with this photograph here, annika.jpg. So go ahead and open that one up and also open up this document, resize_instructions.jpg. Next, navigate your Window pulldown menu and choose Arrange. I want to arrange these so that we can view both images at once. We can do so by clicking on 2-up Vertical, so we can see these side by side.
Next, click in the image Annika and then press the Spacebar key and click and drag to reposition it, just so that we can focus in on the picture. This is a picture of my oldest daughter Annie. Let's take a look at how we can resize this one, and let's follow these instructions over here. To open up the Image Size dialog, you can go to Image and then click on Image Size. Here, you can see we have this dialog open, and there are a few steps that we want to take in order to properly resize this picture.
And let's say that what we want to do is we want to change the overall dimensions of this photograph so that we can print this smaller. Currently, this is printing as a 10x6 at 240 pixels per inch. Well, we want to change the size and also the resolution. In order to do so effectively, we have to go through these sequence of steps, and we have to follow this order. The first thing you want to do is turn Resample off. By turning this off, what it will do is it will disable the pixel dimensions.
In other words, as we make changes here, we won't add or remove pixels, and that's really important. You want to next, then, choose your resolution. Typically, people start off with printing, say, at 300 pixels per inch. That's a very common resolution, so let's go ahead and choose that here. After having defined the resolution, the third step is to turn Resample back on. So here we'll go ahead and click on that Resample icon. The final step is to resize. We can do resizing with this dialog and also with the Crop tool, as we'll look at in some other movies as well.
For this fourth step, this resizing step, we need to make sure we're choosing an appropriate image interpolation. The best one for photographs is Bicubic Automatic. Therefore, whether you're increasing or decreasing the file size, it will then pick the appropriate interpolation which will work best for your picture. Well, now that I've done that, I want to resize this picture. As I mentioned, I want to print this in a way that's smaller. I'll go to the height and press 4. So, now I can print this out. It's about a 4x6. I could go to the Width and take this up as well.
So, I'm approximately at a 4x6 print. You'll notice that when I made these last changes with Resample on, my file size decreased. It went from about 12 megs to now about 6 megs. And the reason that happened is because with Resample on, when you make changes in this area, well, it gets rid of information. That's why previously we had that checked off, but now after defining a resolution, we want it turned on and then we can choose the appropriate size, in this case 4x6. In order to resize this image, you simply click OK, and that will then resize the document.
Here, we can see our newly resized photograph. Just to double check the image to make sure that it's good, you can go back to your image size dialog by going to Image and Image Size. And here you can see that basically what we have is a 4x6 document. It rounded those values off for us, and we can now print this image at 300 pixels per inch.
