Photoshop CS6 One-on-One: Fundamentals is a concise and focused introduction to the key features in Photoshop, presented by long-time lynda.com author and Adobe veteran Deke McClelland. This course covers the image editing process from the very beginning and progresses through the concepts and techniques that every photographer or graphic designer should know. Deke explains digital imaging fundamentals, such as resolution vs. size and the effects of downsampling. He explains how to use layers to edit an image nondestructively and organize those edits in an easy-to-read way, and introduces techniques such as cropping, adjusting brightness and contrast, correcting and changing color, and retouching and healing images. These lessons distill the vast assortment of tools and options to a refined set of skills that will get you working inside Photoshop with confidence.
Now let's talk about the file formats that are designed to work with flat image files starting with TIFF. Now TIFF, which stands for Tag Image File Format is the most popular image format in print design. And the reason is that it's widely compatible and it features lossless compression. Now technically, TIFF does support layers. So you can save a layered document to the TIFF format without losing anything. But there are two problems: one is, TIFF always goes ahead and saves a flat version of the image along with the layers so you get bigger files than you do with PSD when Maximize Compatibility is turned off.
And the other issue is a matter of tradition. Most folks that work with TIFF don't anticipate that the file might contain layers. The one exception might be if you want to preserve transparency in an image. For example, I'm going to select the background and then Shift+Click on royal violet to select all four of these items in the Layers panel and then I'll press the Backspace key or the Delete key on the Mac to get rid of them. And now let's say this is exactly what I want. I want this transparency along with this drop shadow and so forth to be preserved when I take this image into InDesign or Illustrator, or what have you.
Well I don't need the differentiation between the other layers, so I'd go ahead and Shift+Click on sepia, so all five remaining layers are selected. And then I'd go up to the Layer menu and choose Merge Layers, in order to fuse all those layers together. Now presumably I don't want this layer to be called sepia. I'll call it artwork instead. And then I'd go up to the File menu and of course choose the Save As command so I don't end up overwriting my existing file. And then I could switch to file Format from PSD to TIFF and give the image a name, make sure that Layers is turned on and click the Save button.
But here's the thing, even though you can work that way and you maybe called upon to work that way as well depending on your client, we're actually better off saving to the PSD format instead, because InDesign and Illustrator and all those programs that support TIFF with transparency also support PSD with transparency. All right, I'm going to go ahead and cancel out of the dialog box here and switch over to my photographic panorama. And let's say this image is bound for some sort of print publication or even an eBook.
And so I'm going to save a flat version of the image as a TIFF file. Well one thing I could do is go up to the Layer menu and choose the Flatten Image command to fuse all the layers together, and then go ahead and save the image to the TIFF format. Or I can just save a copy of the file. Let me show you what that looks like. I'll go up to the File menu and choose the Save As command. And I'm going to switch the format from Photoshop to TIFF down here at the bottom. And I'm going to rename this file Antique theater, and I'm going to turn off my Layers check box.
And as soon as I turn Layers off, I get a little warning here, that's fine, and As a Copy automatically turns on. What that means by the way is there will no longer be a link between the active image, the one that's open here in Photoshop, and this image that you're saving to disk. So in other words, I will not rename this file. It'll still be called Theatre Antique d'Orange.psd, which is when you think about, just as it should be. Now I'll go ahead and click the Save button in order to bring up the TIFF Options dialog box.
Now by default, Image Compression is set to None, which you may figure is a good thing. A lot of folks have it in their mind that compression, where image file is concerned, is always bad. It's actually not true. LCW is an entirely lossless compression. It works in much the same way as ZIP and other compression algorithms work. In other words, nothing is lost in the translation, and it delivers much smaller image files. So I recommend you turn it on for every TIFF image you save. Pixel Order should be left alone, Interleaved is what you want.
Byte Order actually doesn't matter. You can select PC when you're working on a PC or Mac if you're working on a Mac. But just about every application that supports TIFF supports both variations on the file format and certainly all the Adobe applications do. Save Image Pyramid, leave that turned off and then down here at the bottom you may see the Layer Compression options, if so it should be set to Discard Layers. Then go ahead and click OK in order to save off that image file. You may get a progress bar down in the lower left corner of the image and once the file is saved, note that the layers are still intact even though we just threw them away, and there's no link between this open image and the TIFF file is saved to disk, because once again, it's a copy.
And that's how you go about saving a TIFF version of your image file here inside Photoshop.
