What works and what doesn't with Content-Aware Scale

Video: What works and what doesn't with Content-Aware Scale

All right gang, in this exercise, we are going to take a look at the details that have gone wrong inside of the otherwise really splendid Content-Aware Scaled image and then we'll see ways to fix our problems in the next couple of exercises. One way that's officially endorsed by Adobe, but quite difficult and doesn't work that well. And then another way that I have discovered and it's really simple and it works pretty darn great. So, let's see what going on here. I have gone here and saved the stretched version of the dock, the image that I reformatted, so that it is horizontal instead of vertical, landscape instead of portrait if you will, using the Content-Aware Scale command and it's called Stretched dock.psd. So, this is the Content-Aware scaled version in other words.

What works and what doesn't with Content-Aware Scale

All right gang, in this exercise, we are going to take a look at the details that have gone wrong inside of the otherwise really splendid Content-Aware Scaled image and then we'll see ways to fix our problems in the next couple of exercises. One way that's officially endorsed by Adobe, but quite difficult and doesn't work that well. And then another way that I have discovered and it's really simple and it works pretty darn great. So, let's see what going on here. I have gone here and saved the stretched version of the dock, the image that I reformatted, so that it is horizontal instead of vertical, landscape instead of portrait if you will, using the Content-Aware Scale command and it's called Stretched dock.psd. So, this is the Content-Aware scaled version in other words.

And then, I also have this guy Squishy. jpg, which is the version that I created using the Image Size command which is clearly appear able. Let's go back to the predecessor here and let's look at what's good about it. This post looks awesome and this post has a slight problem, we'll come back to it in a moment. This post looks pretty dam good. All these details around here look great. The bird looks awesome. This bird looks awesome, so all the birds were well protected. So that's nice. We have the sort of weird thing with the fog rising over the tree and getting a little harsh right there at the top of the tree, a little sharp I would say compared to its former blurry self. But the background doesn't really bug me too much. There are some choppy details here and there but it's pretty good. This is about as choppy as it gets right there, we have real jag going on there. But will anyone notice? If we are going to notice something, they're going to notice the details that have gone wrong inside the dock.

So, let's go ahead and zoom in on those details. Right there, we have got a bent post or whatever that is, that support and then we have got another one at this location and who knows there that one would covered up, but this post is fine. So, it must be okay. These guy has got two jacks in them and then we come down to the axis they have got some real problem. This guy has gotten really stretched. This guy is sort of doing the wobble number right there and so on. Then we have sort of different problems going on different points. This is something very interesting to note is this kind of behavior right there.

See how that chip just came out of the word and then we have another place right there where we have a horizontal striation pattern where the pixels have just kind of moved apart like faults in the earth or something along those lines. This is very typical with Content- Aware scale, when it fails, this is how it fails and the reason is because it uses a choppier interpolation method than the Image Size command does. So, it doesn't tend to go in there and calculate using bicubic interpolation, and I have to say I'm not sure if that cleared it or not. I'm not even sure if that's possible giving that what it is doing.

Because I really don't know what's going on under the hood here. But I do know that it tends to move pixels as opposed to stretching them or creating softness between the pixels. So, it does less to smooth out transition, soften transitions or create anti-aliasing, then just shove pixels around and that's most evident with this line right here that is coming off the dock. You can see how the line is just moved over several pixels here, like two or three pixels over and same with this point here, just been shoved over and then this are has gotten really ratty as well.

And then you can also see it on this little bit of the post there which is moved several pixels over to the right with respect to the rest of the post. All right, so that's the kind of thing you have to watch out for with Content-Aware Scale and it will happen with the tiniest little details, the really small stuff, is this stuff that tends to go. So, you need to keep an eye on it and especially things like this. This line right here. That's exactly the kind of thing that is going to go self on you. You are not going to see it unless you're really looking for it and you'll put your image out there and I swear to you, a year from now especially, people will be able to see bad Content-Aware Scale from 5 miles away. It will be the kind of thing that people are really glued into. So, you want to watch that.

How do you address it? How do you avoid it? Well, I'll explain that over the course of the next two exercises.
