Adaptive Wide Angle

We're going to trot right through all of the filters in order starting with dented the done the adaptive wide angle filter oh yes so this is a lovely image of course she been shot by my girlfriend karen ace karen nice will more now so happy about that so here is the original image so this filter is great for fixing distortion problems that are common with when you're shooting with wide angle or fish islands is or even when you're shooting for panorama is sometimes you can introduce a curvature well the white angler fish eye and makes things curve that weren't really curved like this horizon right here so what we want to do is fix it we talked a lot about using the upright new upright feature of camera raw and light room yesterday that upright feature is not going to help you in this situation so it will fix perspective problems but it's not going to fix this kind of spatial distortion so we have to have a go with the adaptive wide angle filter and that came along I believe in c s five ...

vitamin c a six but I think cs five so what's the first thing we're going to do dear grasshoppers convert for smart filters, right? So if this document consisted of several layers and you go ahead and activate them but we've just got one here so let's try it up to the filter menu and choose convert for smart filters. Now we're ready to talk back out to the filter menu, and we're in and choose adaptive white angles. He we're just going to go right down this list in order. And this, of course, is the filters keyboard shortcut. So when this dialogue opens it's pretty it's pretty amazing, because the first thing that photoshopped does is it peeks into the meta data of the photo itself to try to find out what camera you shot this with and what lends you had on your camera. And you might see if you've not open this dialogue box before you might see a status bar trot across your screen that tells you that photo shop is updating its lin's profiles, so its database of lenses so it does that to try toe help, figure it help you figure out how to fix the image. So if it finds your particular lens and you can see down here at the bottom, right, we can see what karen used to shoot this. So she used a nikon d two hundred in her linds was a ten point five millimeter, and she shot it at half stop of two point eight okay, so it knows a lot about your image and that's crucial information that fuck shot can use for fixing it to weaken, zoom back out. If it finds your lands like I said, you'll see it down here, but also this correction menu will automatically set itself toe auto that means, hey, I found your info I got you covered, we can do this. So now the only thing that you have to do is telephoto shot what part of the image you want to fix? Because it doesn't really see the content of the image all by itself. So what you're gonna do is you're going to click, and you don't have to activate any tools you're going to click once where the distortion starts, the horizons lifted in this situation. Now you're going to mouse over to the right side of the image, and we're going to click again where the distortion stops. Now I'm gonna zoom in this a little bit, so you can see what happens just when I start to mouse across to the other side of the image, I'm not holding down any modifier keys and look at that blue line. That photo shop is drawing perfectly around the area of distortion. This blue line is called a constraint, so you're really just marking the area that needs to be fixed and when you mouse all the way over to the right side of the image and single click photoshopped immediately straightens that area out, so you're really just drawn a line across what really should be straight in your image, but again, all we did was single click we didn't hold down the mouse button anything. Now, you'll notice that in order to remove the distortion from this particular image, we've got a lot of transparent pixels going on here all the way around the image. You've got several choices. When we get out of this dialogue box, you could crop out those transparent pixels. You could grab a seriously large frosty beverage and try tio build that area back with some of the content aware tools or the clone stamp tool. Egads, or, more simply, you can simply scale up the image, enlarge it a little bit so that you can crop out those sides right here in this dialog box, and to do that, we're going to use the scale slider over here on the right hand side, so if you want to make the image a little bit larger in orderto end up with the full frame, instead of having all those transparent pixels, then grab the scale slider, and you're just going to drag it to the right. So if I was doing this image for, really, I would probably stop right here, and then when I get back into photo shop after accepting this filter, then I could choose to either crop the image in such a way, you know, maybe about right here, so that I get rid of those transparent pixels or this will be pretty easy to build that area back with either content aware or perhaps the patch tool set to content aware would do a good job with that so that those were a couple options for you, but that's, what that scale slider is all about, so it just depends on how you want to crop that image so we can go ahead and say, ok, and here we are back in our document, so at this point, we could press see to grab the crop tool, and I'll just leave the crop aspect ratio set to original, and I'll just pull that down the top part of the crop box, and then we've got our image while you're in the act of crossing actually glad that little thing happened on screen a lot of times photo shot will temporarily turn off the effects of smart filters while it's processing other edits. So when we accepted that crop, it needed to temporarily turn off a smart filters for just a second while it concentrated on cropping the image because what happened in the document was a soon as I accepted the crop are distorted image came back, but then, when photo shot finished the crop. It turned the smart filters back on, so we have what we expect, so don't let that throw you for leave don't panic when that happens. So if you're doing other edits on a smart object that has smart filters applied tio, there are sometimes when photoshopped will temporarily topple those off while it's processing and then it will pop it back on when it's finished. So that's, what happened here so let's? Just go ahead and undo a few times. Let me give you a little fabulous tip. Probably worth the price is class actually. So you know you can undo backwards one step with commander control z you can actually step backward through your history pale even further like to the last twenty things he did by adding another modifier and that's option on a mac or altana pc. So as I press command z or command options, he control all too busy on the p c I can keep tapping z and I'm stepping back through my history panel so that's ah, he were shortcut for multiple and use so let's just take a spin through that one more time, shall we? So here we are back at our original image, so activate the layer or layers choose filter, convert for smart filters. Go back it to the filter menu and choose adaptive wide angle now you'll notice that adaptive wide angle also now appears at the top of the filter menu that command that appears that there is always a last filter that you ran so we could trigger the same filter by pressing command if or control f on a pc so now we're going mouse over to the left side of our image where our distortion starts it's not holding down the any modifier keys or the mouse button mouse over to the right side of the image and click once where the distortion ends and photoshopped fixes it right up use the scale slider if you'd like to enlarge the image to kind of crop out some of those transparent areas click ok and then again you can choose to either rebuild any transparent areas or more simply just cropping right out now I've got my aspect ratio menu set to be true to the photos original aspect ratio so their relationship teo between width and height so that's why as I had dragged this middle box the whole crop box is changing because it's preserving the photos original aspect ratio and then when I finished this press return see photoshopped temporarily turns off the smart filter when it's finished processing the crop than it turns it right back on so if you need to get back into that filter for any reason what do you do just double click the filter in the layers panel just give it a double click it will pop back open and you can continue to make changes let's say you've got a slew of images that have the same problem then you could choose save constraints and then when you pop up in those other images you could say load constraints so you that keep you from having toe draw the constraints yourself but it's pretty easy to use so any time you get that kind of special distortion things that have occurred that ought not be curved and that kind of thing from shooting with wide angle or fish eye then this would be the filter that you could use to fix that question the scaling within that that last dialog box is that scaling actually larger than the image itself it's it's scaling it the image up yeah, a plate up same pub sampling great. So in the next second part is do we know how it's doing that? I don't that's a really good question. Okay. I wonder if it uses automatic automatic. Yeah. That's what I was wondering yeah, I know the crop tool does when you activate the crop tool in if you type in any if you use the cops will to resize your image to be larger than the original dimensions it does use automatic for the re sample algorithm and in cc automatic, when you're going up in size, uses the new algorithm called preserve details that does a little bit of sharpening and try to tries to keep the areas of fine detail sharper in your image so that when it's blown up, it doesn't look all soft and mushy and blurry. But that's a great question. Jim sciutto. I wonder what the adaptive wide angle scale slider, which method it's using good looks like maggie, might have a quick lunch. Um, if you wanted to go the other way, say that you wanted to introduce that curve into an image for whatever artistic reason. Would that be the filter that you would use? Sure, absolutely. You can use the same filter toe, push, pull around, distort your image and all kinds of fun ways. Yeah, absolutely. And doing it safely with smart filters. You know you don't have to worry about tearing up the original image. If you don't like what you did it, just grab the filter itself in layers panel and drag it down to that trash can icon.
