Photoshop CS4 for Photographers is an essential course for any digital photographer who wants to master the software's vast array of image enhancement techniques. Professional photographer and instructor Chris Orwig uses his own compelling images to demonstrate how the power of Photoshop can make photographers more passionate about their work. He covers many aspects of the application, such as working with RAW images, using curves and levels, making images snap, and enhancing bland photographs by converting them to black and white. Exercise files accompany this course.
In this movie we will be working with the file corwig_antiques.CR2. And that we have talked a little bit about image size, about image resizing, about image size considerations, let's actually talk about how we can resize this particular image. We are going to select it inside of the Bridge. Hold down the Shift key and then double-click it to open it up in Photoshop and skip the Camera Raw dialog. That's a great shortcut; Shift+double- click from Bridge skips Camera Raw. Well here we have this photograph, inside of Photoshop we will press F, we will then double-click the Zoom tool, take it to 100%, wow! Okay, well we can see we have nice detail here. The image is relatively sharp.
We want to resize this image. So what we are going to do is use our shortcut or 'long cut,' Image > Image size. The shortcut is Option+Command+I on a Mac/Alt+Ctrl+I on a PC. That will open up our Image Size dialog window. Now you may remember this from our previous conversation we have had in a previous movie, we had talked about pixel dimensions and document size. This has to do with the print, this has to do with the actual pixels, all we are concerned with, the actual pixels, the resolution doesn't matter and here is why? We can't change the resolution of web images. The resolution is contingent or dependent upon the resolution of the monitor.
Where when we print, we actually can't change the resolution. So all I want to do is change my numbers up here, 700, that makes this image 700 by 467, Bicubic Sharper, click OK to apply that, double -click the Zoom tool and make sure we are at a 100%. Great! Now some of you probably aren't convinced. Okay Chris, why do you skip the resolution? Well let me show you. Image > Image Size, I'm going to click Resample off, change my Resolution to 2000 pixels per inch. That's crazy, right! How can I do that? Well, click OK, double-click the Zoom tool, well there is no real change in the image, right. How can that be? We will go back to the Image Size dialog. Again this has to do with printing; this doesn't matter to us. So when you are working on your images, keep in mind the resolution is dependent upon the monitor, or most concerned with these numbers here. We know a little bit about what numbers are best because we have talked about that in the previous movie, right.
We talked about how we are designing or thinking for this 1024 by 768 space or something similar to that. We are going to then go ahead and create the file that way. Well on a Mac/Command+ Option+Z; on a PC, Ctrl+Alt+Z, and keep pressing Z until you toggle back to the full size image. Well there is another tool that you can use for resizing your images. It's the Crop tool. Go and press the C key on your keyboard, now we have the Crop tool, we are going to do zoom out, so we will go ahead and zoom out on this one, Spacebar to reposition. I'm going to enter in 700. Now, if I just hit 700 and then tab, it's going to say 700 inches, that's my default measurement. Wow, that will be a big document.
So, what I need to do is 700 px for pixels and then for my height, I have a couple of different options. I could enter in a specific number or I could let the height take care of itself, and let me show you what I mean. Resolution, we don't touch that, right it doesn't matter, all that matters are the actual pixels. So I'm going to click and drag and extend this across the entirety of the image, double-click to apply, now double-click the Zoom tool, all right. Let us go to that Image Size dialog window, Command+Option+I on a MAC/Ctrl+Alt+I on a PC. We'll take a look. The height took care of itself. What happened was it said okay, well to resize this image to 700 wide, it has to figure out the height and the height then had to be 467. Well let's say that what we want to do and in contrast to that is enter in a value for the height.
We can do that, right. So go ahead and zoom in back here, grab the Crop tool, which is the C key, and I'll go ahead and type in 400 px for pixels. Resolution doesn't matter. And now when I click and drag, it's going to confine the proportioned to those proportions, 700 by 400, double-click to apply that. Go to Image > Image Size. It's now those exact dimensions. All right, well I actually don't want that crop, so I'm going to undo that. Well the crop that I do on is 700 by 467, so I'll go ahead and drag my crop without a height dimension there. So I'll go ahead and enter in 700 px, drag my crop across the image and double-click to apply that and then double-click the Zoom tool. Just to get a feel for the overall image size. I'm trying to envision this image, inside of either my e-mail program or inside of a web page and I say you know what? I'm tack on. This is the exact size that I want for this image.
And now what we need to do is talk a little bit how we can sharpen this image and in addition, what we need to do in regards to the coloring contrast and the color space in order to prepare this file for the web. And we will talk about those items in the next few movies. So go ahead and leave this image open because we will continue to work on this one.
