Join Mikkel Aaland for an in-depth discussion in this video Watermarks to metadata: Maintaining image integrity, part of Creating Photography Ebooks.
In this video I'll show you a couple ways to protect the integrity of your images. And help keep them from being ripped off. At this time, epub devices display limited resolution. The Amazon Kindle, for example, has a 64 kilobite limit on the size of graphics used. In the future however high resolution devices will likely be the norm and there will always be those who take advantage of harvesting professional images from an epub book. Well, what to do? A standard means of protection is embedding metadata into an image that clearly states copyright and ownership. So what happens to this metadata when it's processed through Adobe InDesign 5.5? Let's see, so I'm going select this graphic here in my document, under file, file info, now look here under the IPTC tab, you can see all this information that I put in earlier in bridge. It exists there.
Just, it sits with that file. It is contained within that image file. So far so good. Now, let's see what happens when I export this file. Export, Export to epub. Put it into the county fair assets folder. File save. I'll place that original file and I'm going to say here, include document meta data. This is not to be confused with image meta data as you're going to see shortly. And now I'll select OK and InDesign is generating the epub document.
It opens automatically in Adobe Digital Additions. Everything so far, so good. Yeah, but, what about the information that I attach to that image? What happens to it? All right so you're going to have to bear with me a little bit. We're going to do some hacking here. So I'm going to go to my folder, let's go here into the assets folder, there, there's the e pub document that was just created by end design. Bear with me again, we're going to hack this thing. We're going to open it up and see what's inside of it. In order to do that, we're going to have to do a couple things. I'm going to right-click and I'm going to duplicate it first of all. Now I have a duplicate, I don't want to mess with the original, have a copy. So, I'm going to select this.
I'm going to change the extension, let's get rid of the word copy here. Now that. And then we'll change the extension from ePub to zip. All right now it's going to ask me do I really want to do that? Yes I really do, thank you very much. Okay, so now it has a zip extension on it. If I right-click on it now, and open with, and I have StuffIt Expander loaded. So, this is required for this hack to work. So I'm going to use Stuffit Expander, which is a free download from the website.
And I'm going to unstuff it. And now I have a folder. Ooh, what's in this folder? Interesting, huh? All right. So you can see this. Let me double-click on it, so you can see it better. This is what is contained in that epub package. A epub is not really a format, per se, it's really a packaging of information. Let's open this up. And you can see, that's the XML files and if we double-click on this, we have all kinds of files, we have HTML files But this is the file that I'm interested in here, the Images file.
I want to see what happened to my JPEG that was generated on the export from InDesign. Let's open that in Photoshop. Photoshop, and take a look at it, because that's a good way to check out what has happened to the IBTC data. Under File And then we want to find file info, and there we go. Nothing. It's all been stripped away. All right, well, first of all you an see someone who is determined can hack into your ePub file. That's one thing.
So those photographs that sit in that folder can be grabbed. And you know, there we go, there's no copyrighted information attached to it anymore, it just exist in the world with out any data attached. Okay, what do we do now? Well, there's a couple ways to go, if you really are concerned about it, you see here this folder that contained all the images. Those images can be swapped out. You can come into this folder and replace these images that have no xf data, no iptc data with files that now this is the important thing they have to have the same resolution, exactly the same file name.
You can go in, swap them out, and then you will be able to maintain all that information in the metadata. Okay, it's a little bit tedious. It is a workaround, it is something you might consider. Another way to go about maintaining integrity in your image is to simply just add a watermark. And there are a lot of ways to add a watermark. Let me just go ahead and show you one very simple way that I would consider doing with this image. This is the ping, graphic that I created earlier with a transparent background. I could very well easily just grab that ping, graphic, put it into my image, Resize it, obviously, it's a little too big.
Let's drop it down in size. And because it's transparent, I can put it anywhere onto the image and you know, it's transparent. Let's see how that works. And then, under the, over here, after I've committed it I can go to the layer and just bring the opacity down so that it's just a faint, let's see. You can see, acts more like a watermark in the background. Okay. So I can go through in, individually to all the images and do that either with a graphic, with a transparent background or I can just type my name in it using the photoshop type tool. And position it some place where it becomes a watermark. There's also a cool extension called Adobe watermark that Russell Brown offers for free on the Adobe site that he's created that will autmatically either place a watermark graphic into your images.
Or, you can just type it in if you want, type in the text. It'll batch apply the watermark to multiple images in the folder. Only downside to this, which, it's a really cool, it's free, you can just go get it from the Adobe site. It's really cool, but it only creates the jpegs. Which is fine if that's what you want. If you want tiff's as a result you can't save it as a tiff. Now the last way I'm going to suggest for making the watermark is just through Lightroom, Adobe Lightroom. That's another application I'm trying to stay within the Photoshop bridge in design world here. It's very easy to create watermarks in Adobe Lightroom. I'm sure in the future there will volve other ways to protect the integrity of your images.
These are just some suggestions that can be implemented right now.
