Lesson 6
* Saving layers to the native Psd format
- Go ahead and click on the "Don't Resolve" button, because, if you scroll up the list here, you can see that the one and only editable type layer is actually turned off, so it's not even visible at the moment. Let's say what wanted to do is get rid of all the hidden layers inside the image, so don't get that font warning again. In that case, would click on the Fly Out Menu icon in the upper right corner of the layers panel, and choose "Delete hidden layers" to get rid of them. And then, in response to the alert message, click on the "Yes" button in order to make those layers go away.Now you can see that have an asterisk outside the parentheses, which tells me that have unsaved changes. Which means that I could update my existing file by going to the File Menu and choosing the "Save" command, or you have that standard keyboard shortcut of "Control S", or if you wanted to save an independent copy then you would choose "Save As", which has a slightly different keyboard shortcut of "Control Shift S". But before you do, visit a preference setting. And to get to it, go to the Edit Menu here on the PC.
* Saving a flat print image to TIFF
- TIFF automatically goes ahead and saves a flat version of the image along with the layers, so it generates larger files then you get using the PSD format with maxAlso it's a matter of tradition. People who get TIFF files do not expect layers to be inside them, so it can really thrown for a loop and when you're passing off an image for print you generally want to keep it as small as possible. So let's a want to save a copy of this layered image in the TIFF format. It would go up to the file menu and choose the save as command. Or got that keyboard shortcut of control shift S or command shift S on a Mac. Just go ahead and call this guy pre-press cover let's say and then change the file format from PSD to TIFF which by the way stands for Tagged Image File Format.imize compatibility turned off. Now notice that for some reason Alpha Channels are turned off right here and as a result as a copy is turned on. If wanted to save Alpha Channels It would go ahead and turn Alpha channels back on and generally TIFF is great for Alpha Channels. So folks expect Alpha Channels to be in to TIFF files just so you know. They don't expect layers, so go to go ahead and turn the layers checkbox off at which point the as a copy checkbox will be turned on. Now what that means is we will not be changing the name of the file that we're working on and if we make some changes to it and then go to the file menu and choose a save command, we'll update the original PSD file because there will be no link between the TIFF file that were about to create and this document.
* Saving an interactive image to Png
- Step one is to go up to the window menu, and choose the Channels command in order to switch to the Channels panel. And what wanted to do is take what seeing and convert it to a selection outline.So in the world of masking inside Photoshop, anything that's white will become selected, and anything that's black will be deselected. And to convert what we're seeing to a selection, you just drop down to this little icon down here at the bottom of the panel, the Load Channel Selection icon, and you click on it, and that selects the background without selecting the horse. We actually want things to work the other way around. So go up to the Select menu and choose the Inverse command.Alright, now let's go ahead and open that file we just saved by going up to that File menu and choosing the Open command, or pressing control-O, or command-O on a Mac. There is the file right there, at which point go ahead and click on the Open button, and notice it appears as an independent layer. Now it does not retain its name, which is Fountain, as you may recall. And also, we don't have the layer mask. So this is the actual PSD file right here, complete with the layer name Fountain, and the layer mask. Whereas inside the PNG file, we just have a static layer.So in other words, everything outside the layer mask has been clipped away. Meanwhile, It can open the same image such as in this case, Chrome, at which point It can zoom in by clicking on the image in order to get this amazing degree of detail. And that's how you save an interactive image, whether for a device or for the web, as a PNG file, complete with transparency, inside Photoshop.
* Saving a flat photograph to Jepg
- JPEG does have its limitations. It is in no way, shape, or form capable of saving layers, nor does it support transparency, and it always relies on lossy compression, meaning that it has to rewrite the colors of pixels when it saves its files.But in return, you get much smaller file sizes. So, as you can see down here in the lower left corner of the window, this image takes up almost 43MB when flat, and then this value after the slash tells us it takes up 166MB in memory with layers. On disk, the native PSD file weighs in at 140MB, so a little smaller than a layered version in memory thanks to the PSD format's lossless compression, whereas the highest quality JPEG file takes up less than 9MB, or about 6% of the size of the layered PSD file.You want just standard, regular old JPEG. And then go and click on this file that going to replace, Yorkminster Facade. Now again, notice that all the options are dimmed, and As a copy is turned on because you do not have the option of saving Alpha Channels, or Spot Colors, or Layers or any of those things. You can save Path Outlines along with JPEG files, by the way, but that's about it. And so next, what going to do is click on the Save button in order to save that image, and click on the Yes button in order to replace the existing file.Baseline Optimized goes ahead and applies another helping of compression but this time lossless compression, which generally helps to get the file size ever-so-slightly smaller, and these days every thing that supports JPEG, supports Baseline Optimized. So, it's the way to go. Alright, now go ahead and click OK in order to save that file. Alright, now let's go ahead and open the file, either in Photoshop or in a web browser. Go ahead and switch over to Chrome here, and press Control O, to open an image file, and find that guy we just saved, yorkminsterfacade.jpg, and click on the Open button. go ahead and click on the image with the zoom tool to zoom on in, and we might as well zoom in on this location right there that's got all this detail here. And you can see that the image looks absolutely great. We're not seeing any vestige of those 8x8 squares whatsoever even though they are there. They're just a lot more subtle than they were when we were assigning low quality compression. And that's how you save a continuous tone photographic image as a flat JPEG file with no transparency whatsoever complete with lossy compression inside Photoshop.
