Knowing Generative Fill's limitation

“

- [Instructor] Let's take a moment to talk about something that nobody really likes to talk about, which is limitations. Up until now, we've only talked about how amazing Firefly is and the quality of the images, tips and tricks, how to get the best out of your prompt. But it's important to know where the technology is today. And so I've already mentioned that at the time of this recording, the maximum resolution you can get out of Adobe Firefly using Version 3 is 2,048 pixels by 2,048 pixels. Now, anything that goes above that number in a single prompt will look pixelated. Let me show you an example where that might seem very, very clear. So here in Photoshop, I currently have this document open, it's called limitations.psd. And before we do anything, let's take a look at the image dimensions. I'll just go ahead and choose Image. I'll choose Image Size. And so, this document measures almost 10,000 pixels by roughly 5 1/2 1,000 pixels. That's a lot of pixels. Now, let's go ahead and click Cancel for now. And let's take a look at something that we would want to do using Firefly. So I have expanded the canvas downwards and now I would like to generate more content in this area. Now, you can do this by either using Generative Expand or by using Generative Fill. The principle is the same. I have a very large body of pixels that I would like to fill using generative AI technology fueled by Adobe Firefly. So what I could do is the following. I could potentially just take my Rectangular Marquee tool, I can just go ahead and just click and drag a very big selection that covers this empty area, and it's also slightly overlapping the area of the known content. That's a pretty good practice, by the way. And now with nothing selected, I'll just go ahead and click Generative Fill and then click Generate again without a prompt, which means fill this up with more content, which is exactly what Generative Expand usually does. I'll to go ahead and click Generate. And now I'm asking Firefly to generate 5 1/2 1,000 pixels in width. And then, I'm guessing 1,500 pixels in height? I'm not quite sure. Anyway, there are a lot of pixels. Let's give it a few seconds. Now, it's done generating everything and you think to yourself, wow, that looks absolutely stunning. This is the first version, second version, third version, so you've got different variations. Let's go for the first one. Now, I'm going to zoom in a little bit by choosing the Zoom tool like so, and I am going to just pan a little bit downward and notice this. Do you notice a transition that goes from this area of the image that seems to have a lot more detail to the bottom, which is, looks a bit like a soup basically. So this is something that becomes very, very clear the moment you start to zoom in or the moment you start to look at this image in actual size. Now, the reason this looks, well, this bad, is simply because we have surpassed Firefly's limits by requesting too many pixels at the same time. So what do you do? Well, we can wait for the next version of Firefly to come out and address the number of pixels being generated, but for now, I do have to make sure I have a decent-looking project, so we have an alternative way of working and we can use a workaround. Now, let me show you how that works. I'm going to go ahead and just delete this later. And instead, we're going to be choosing the Marquee Selection tool again. And I'm going to change this option from Style to Fixed Size. Now, remember, the maximum that we can generate in actual resolution is 2,048 pixels by 2,048, let's just say roughly 2,000 pixels in either direction. And so, I set this up by using that maximum of 2,000 pixels. So I'm setting the limitation here as to how many pixels I can generate at a time. I'll simply click to generate that selection, which now measures 2,000 by 2,000 pixels. And I'll position this here in the bottom-left corner, something like so, maybe a bit lower because I don't need that much in height. And with that current selection, simply click Generative Fill, and then click Generate again, after which Firefly will start to expand the image. Now, not fully, but only within this big 2,000 pixel square frame that I have. Now, let's give it a couple of seconds here and now, this is what the result looks like. And if I were to zoom into the result, you will see that now I don't have this awkward transition going from good quality to meh quality. And so, now I have leveraged the full potential, the full quality potential still, of Firefly. Now, how do you keep going? Simple. You simply fill more. Let's go back to the Selection Marquee tool. Let's place our next selection. Be sure there's a bit of overlap on every side. Click Gen Fill again and again, and you keep adding to this image time after time, like you're building little tiles, and you just do one generation command at a time. And that way, you still have the ability to fill a very large area with data, not surpassing the available quality, using Adobe Firefly.
