Shake Reduction Filter

We're gonna start working on photo shop see, sees new filters and there are a slew of them, so we'll probably have time to get through the shake reduction filled her first, which, you know, sometimes adobe does it. They just put in this feature that's like absolute magic. We saw that with content aware in cs four for the first time when we got content where scale cs fine, we started getting more and more content where tool cia six we've got more than we've ever had. Well, the new shake reduction filter is another one of those little bits of magic, so we're going toe look at it on a couple of different files and hopefully have time to take some questions on it before we take a break so good and close this image and I've included a lot of images for you to play with in the exercise files, so we're cleverly we're in the cleverly named filters folder here and bridge is going to take just a second or two you to draw me some nice, pretty thumbnails of all the images that are in that folder. ...

So what we've got here are three different files that were going to play with this new filter, and what is this filter do? Best way to tell us to show you. L z a minimal bit here. So this is one of raphael's famous paintings were in the vatican museum. Now we and we are in the room that you're in just before you go into the sistine chapel and I was shooting with a really long lindsay my gear sponsor limbs protego lens pro to go dot com fabulous folks hooked me up with a seventy two, three hundred millimeter l siri's cannon lands insert your own drool here to shoot with so this painting was far away from me so often times what happens when you're shooting, you know, with a long lens like that or in low light? Or what have you? You will get a little bit of kaymer shake because without shooting with a tripod that lindsay is heavy, I can't but help when I depressed the shutter, I'm going to move that camera is a little bit so inter photo shop ccs new shake reduction filter it reduces blur caused by camera shake this is not the original watch when I turn off the visibility I yeah, baby that's the original so while I wouldn't say that this image is suitable for selling, I can sell this in an image anyway, because it's a you know, raphael's paintings anyway, it saved the image I mean, it may not save it to the point that you needed it to be, but really, what this filter is is for fixing camera shake so it completely save the image. It may not be sellable or my piece of best work, you see, but it totally saved it. So any time you've got a little bit of camera shaking, the images is a great filter use again, here's the before. Imagine how heartbroken I was when, because this is one of my favorite paintings that's neat because rafael put a lot of famous people in their sprinkled throughout he's at the far right of the image. Actually, so I was a little ticked off when I looked at this, when I important all the photos like dad, gam it's blurry, I don't worry about that anymore. Shake reduction filter so let's, take a look at how it works, and again, when you purchase the the course, you're going to get all these layered files, you can see that I've got everything set up for you, but what I've also included is another original for you to start from. So the way the great way to use these exercise files is to practice with and reverse engineer what I've done, so all you need to do to start over is just turn off the visibility of the final layer that I've made for you and then you can come down here and you can start again with the original stuff kind of how I have said if those extra how's fouls free so let's zoom back out so let's just do that since this is a filter we have the ability to run filters non destructively we're going to cover filters for hours and hours tomorrow in our filters deep dive but today what I want to show you is how to run the filter non destructively so we're going to trot up to the filter menu and we're going to choose convert for smart filters now because I only have one layer active it's going to change that one layer really turns it into a smart object ready, which means the filters are going to run on destructively in their own little space and layers pale. But if this were a multilayer file let's say this was an image that I'd color corrected and etcetera, etcetera, etcetera and some re touching on all you have to do is activate all those layers in your layers panel and then choose filter convert for smart filters and photo shot will bundle up all of those layers into one smart object that you can then run the filter on so activate the layer or layers in your layers panel first and then trot up to the filter menu and cheese convert for smart filters when you do, you get a special little badge on the layer self that little a special icon at the bottom, right? That let you know that it's a smart object, we'll talk way more about smart objects tomorrow morning, so I hope you'll come back for that. The next thing we need to do is coming to the filter menu again. And now we're going to come down to the sharpened category that's for the new shake reduction filter lives, so give it a click. The world's largest dialog box well been take over your screen. He had a nice big preview of what the image is going to look like, and automatically. It happened really fast, so let's do that again. Photo shops going to analyze the center portion of your image there it went to see that will status fargo by on this detail section over here. So what it does is it looks at the center portion of your image and analyzes oh, about a one inch by one inch screen resolution. Spot. Okay, and it tries to look for the direction in which the blur is occurring in order to trace the blur. So if it can figure out the pattern or the direction, and with of the blur, then it can eradicate it throughout the whole image. Now what portion of your image did photoshopped analyzed like I said it's usually in the center but if you want to see exactly what part of it it analyzed or let's say if you want to move that area of interest to another portion of your photo let's say where the focal point is then all you have to do is click this full flippy triangle which is an actual technical term flippy triangle click that one guy right there and you reveal this advanced panel which is really incredible first of all his email what you immediately see is the area that photoshopped picked to analyze so that's what this bounding boxes that showing you that anything inside of here is the area that photo shop scrutinized in order to figure out how big the blur is in what direction it's going you know did you just move the camera up or down in a vertical fashion or did you kind of move it down in a little bit to the side or did you do this is a zigzag is it a straight line? What exactly is the pattern and the blur so that's what photo shop is figuring out and if you think if you double click or just single click actually on one of the little blur the column blur traces so this would be a miniature of the area of interest the area that's within that little bounding bob so this little area of white and gray is foot a shop showing you the blur trace that it created so you can actually see in which direction did you make of the camera so I obviously moved it a little bit down into the left when I took that shot so that's fun to see you can move this area of interest anywhere around that you'd like so I'm gonna scroll up a little bit while I'm at one hundred percent so I can't see that there we go so see hot grabbed the middle part of the image well let's say that my focal point was really over here well you can grab this little center circle which is a pin and you can discuss the area of interest to somewhere else now as soon as I released my mouth's but you're going to see a little status far photo shop is going to analyze that particular area and forget about the first area that analyzed so here see we've got little status far and we've got a new blur trace going on so let's zoom in a little bit and then let's single click the blur trace icon and now we see we get a slightly different blur trace or blur pattern so if photoshopped doesn't do a good enough job in your opinion on its auto analysis then you can click to open this advanced tab and you can control the area that's analyzed yourself now your next question will be well, can I have multiple blur traces? Absolutely so that's what I usually do when I use this filter so I let photo shot go ahead and do the analysis in the center and then I'll move it tore my focal point is and then I'll do another area of interest or region of interest how do you do that? Just mouse over to the area that you wanted to analyze and collected draw box now you'll notice see how the boxes rid and then it gets when it goes tio black and why while it's rid that's photo shots way of saying hey the box your drone is too small that's too small of an area for me to get an accurate blur trace I love all these new terms blur trace blurt estimation region it's fabulous, isn't it? So now when I released my mouse button letter shop is going to create a second blur trace get the little status far and now we've got another little thumbnail down here in the advanced panel and if we zoom in this particular image, it seems like the blur trace patterns are the same to me. But this would be a great way for you to tell you quickly to straw a couple of these boxes around in other areas that are important in your image and just look at the blur trace icons if they're similar probably not going to notice any difference if you've got one or multiple blur traces going on and these are similar so that's certainly something that you can try the image is really important, but again let's just do a little before and after a preview here I'll zoom in so your zoom controls work inside of this dialogue box, so command plus on a mac or control plus on a pc will zoom in command minus or control minus on a pc will zoom back out while you're in this preview area but always toggle my pretty often on there's the before blurry as all get out and there's after not too shabby in my opinion. So like I said earlier, if you've got if you create multiple blur traces and they looked the same, you can click to activate one and then use this little trash can I call it at the bottom right of the advanced section to get rid of that? And if they are similar, you can delete him if you want. If you've created a slew of these blurred traces and then you need to reopen the style of walks for whatever reason, it might take photo shop a little bit longer to open it because it's looking at all of those areas of interest and analyzing all those different areas so that would really be the only advantage to deleting any of the blur traces you've created if if you find that the blur pattern is the same is just quickness in reopening in closing this filter because photo shop was applying where when we close the filter is going to apply all of those changes to the image if you got a slew of those that might take it a little bit longer but otherwise you can just leave them hanging around so that's neat, huh? The third thing you can do in this filter is that you can draw your own blur trace pattern. Oh yeah so the way you do that and the only reason you'd want to do that is if you're not getting good results with photoshopped or that you just really love taking things into your own hands and doing it l emmanuelli, which is totally fine, so to do that you come up here to the top left of the dialog box and you're going to switch to this blur direction tool when you do all those other blur trace icons get temporarily turned off so you see, we're back to the blurry awfulness of this image so you come over here and wherever you want, wherever you think the blur is you could just click and drag I can see a little bit of the blur right there so you could click and drag in the direction that the blur is going so I haven't released my mouse, but yet that's why you're seeing that changes I'm dragging around. So if you think you can do a better job of drawing in europe, the blur trace pattern manually then switched to this tool and you can do that. But most often times you probably would not need to do it. And when you do, then you get a little read em on the blur trace that photoshopped creates and lets you know hey, that's the manual version in that you drew yourself. Somebody go ahead and delete that one. Here we go. So, again, that's this little tool right up here's, the second one down, blur direction toe keyboard shortcut is our but straight from the factory by default, the blur estimation toll is someone that's active, so depending upon if you've opened this advanced section or closed that's the way it's going to be when you reopen this filter, so don't let that throw you when you first installed a program that flippy triangle is not turned down, so that section is not expanded, so you're not going toe really see the area of interest drawn onto the preview when you first open this filter as soon as you open the advance section. If you don't close it before you click ok to close this dialog box that's going to be open forever more so the settings you making here state changed until you change them back, just like the options bar, but don't let that three I like leaving this advanced section turned down because I like it's just easier to scoot around the area of interest if I want, I can see exactly which area photoshopped analyzed, and I do a couple of more blurred traces if I want, if the whole image is supposed to be in focus that, like, I don't have a real clear focal point, then there's nothing wrong with drawing a few more blur traces on the image, just to try to get the best result that you can, so usually I'll do that, and I'll start turning these guys off to see if they really made a difference or not. So let's, go ahead and you know, also you've got a few settings that you can tweak here will go and turn our preview back on so you can make the little blur trace area smaller or larger with the slider. If you want, you can try to do a little bit of noise reduction with this, if you'd lie, he could do a little bit of smoothing if there's noise that's been introduced from the results of this filter and if you start getting some artifact ng, so basically start kind of seeing the pixels were things start looking chunky, like they're made out of legos. Then you could increase this artifact suppression slider, drag it to the right and photo shock will add a little bit of a blur to those areas to make. I'm not stand out quite so much so there's quite a bit of control tapes I had my microphone, I'm sorry quite a bit of control in this filter, so we'll go ahead and click ok and photo shop is going to apply the changes and because me collapse thes panel see, you can see my layers panel here and I just double click the tab itself in from shops sisi to contract or expand those panels, and we can see that the filter ran in his own little space right down here shake reduction. So if I want to see my before and after, I'm not going to click this eyeball, right? Because that turns off the whole layer you'd toggle often on the eyeball next to the filter names, and now we can see our before and are after another neat thing that you can do using smart filters is that you can double click this tiny, little cryptic icon to the right of the filter name, and you can access the filters blending options, and a lot of folks like to do this and change the blend mode of sharpening filters to something called luminosity basically that's making photoshopped. The sharpening happened in the lightness channel of your document so that you don't get any color shifts, so basically it's looking at the great skill data in your image and oftentimes when you sharp and you can get a little bit of a shift in color. But if you change the blend mode of the filter itself to luminosity shouldn't get any color shift, so here's how to do that double click the little icon and that'll bring out the filters blending options, and when you're he's in the shake reduction filtering, you will get real familiar with this progress bar because it really has to think about everything before it displays a teeth so here's a mod menu right here so we could trot down tio luminosity, and you're probably not going to see much of any difference on this image because we really didn't introduce it in color shifts from the sharpening anyway, but if you did, that would be one way to eradicate any kind of color shifts. And you might just want to do this as a matter of course when you're using sharpening filters, so since we have used smart filters, we can make that blend mo change happened by accessing the filters, blending options dialog box again what you get by double clicking this icon to the right, or if you have done your sharpening on a duplicate layer, then you would simply use the layer panel blend mode, which is right here, and you would change that to luminosity instead of worry and do some of that tomorrow afternoon, so we'll be having lots of fun in the realm of sharpening. Another thing that you can do here in this blending options is you could reduce the opacity of just the filter itself. You really wouldn't want to do that in the shape production filter because you're trying to get rid of the blurry don't want to bring some of it back, but if for whatever reason, you wanted to reduce the strength of just the filters effects than you could do that here with the opacity sitting so let's, take a look at that on two more images and then we'll break for some questions on the shake reduction filter so let's, try it back over to bridge and we're going to open that file number b and this is a shot of in tivoli and hey adrian's fountains hey so hey adrian was actually responsible for rebuilding the pantheon one of rome's oldest pagan instructors after it burned down so hey adrian's a pretty cool dude for that but what we've got here is another long shot is she eating with that amazing lens protego three hundred millimeters in and why did they get it from lindh's part ago because I don't know if I really want to buy where those lenses so why not rent it rented before you by see if you like shooting with it I decided it was too heavy for me so what am I going to buy? I'm going to buy the two hundred millimeter l series instead of the three hundred I would know how that not rented that equipment great way to experiment so we've got blur again because I'm not shooting with a tripod here so let's have another go with a shake reduction filter what's the first thing we're gonna do is we're going to run that filter safely by converting it for smart filters so activate a single layer or multiple layers whatever your document consists of and then tried it to the filter menu and she is convert for smart filters now trot back it to the filter menu choose sharpened shake reduction so I got that nice dialog box here again see how this time the advanced section has already expanded and we can see the region of interest that photo shot picked I'm going to go ahead and re size the style of box a little bit so we can see the whole image and maybe zoom in so let's turn our preview often on so we can see how good of a job for the shot did just with its default settings there's the before pretty blurry there's the after actually did a better job on this one I think I was bummed that some of these were blurry because I did such a good job getting my water all soft and it was blurry so let's take a look at our pattern of blur this time it looks like I moved a little bit down into the right with the camera shake so great for teaching you what you do on these types of shots right like, oh man, I'm always going down a little bit to the left what I should have done actually I think I did do this, but it didn't help a whole lot was positioned my elbows down on some of the concrete and then but I was still holding the limbs and even with the camera up to my face with my a skull giving it a little bit more stability, I still got a little bit of blur in that image because it I just didn't have a tripod so pretty amazing and again if I want to go ahead and add other regions of interest I can do that I could come over here to the bottom wherever and photo shop will keep updating and adding new blur traces and so on so I don't like the effects of that one, so I'll delete that blur trace just go back to the other one and you can change the size of the region of interest if you want and again to scoot around the original one if you don't want to draw additional border traces, so did a pretty good job on that one going click ok and it's applied and again we'll toggle our visibility eyeball of the filter itself off and on so pretty amazing technology here does take a little bit for photoshopped to draw the preview of that filter and again to change the blending options because a double click that little icon to the right of it and if you'd like, you can change the blue moto luminosity to make sure that you don't have any color shifts going on so that's where you could do that so I'll try that on one more image this guy right here here's our before theirs are after let's take a second to draw those previews pretty amazing job pretty amazing job and another great thing about doing this with smart filters that let's say I use the shape production filter and I thought I was happy with an on screen I printed it and I want to see if I can do a little bit better job super easy save this file as a native photoshopped document by choosing file save as making sure photo shop is set from the format or use menu that way your layers are always preserved, so that means to go in and tweak that filter. All you have to do is double click the filter itself in the layers panel, and it will pop right open with all of my blur traces right there, so I confined tune them if I want to you can see over here that I've got to for this particular image, so I've got a little bit of side to side motion and it's a tiny bit of up and down so I won't almost did a little bit of a zig zag or circular thing when I was holding the camera, but I would have never known that it's just a very subtle movement that introduces the blur into your image. Any questions on the fabulous new shake production? There are sam cox from loveland, colorado. Howdy, sam always agreed question person should the shake reduction filter be used earlier or later in the work flow? Great question that is a great question because I always like to save sharpening until last it depends on what you're doing if you're going to be doing some cloning in this image then I would do the shake reduction filter earlier in the work flow really just depends on how much retouching you're going to do, so if you corrected the color and everything and then you're ready to sharp and go ahead and do then, but honestly on shake reduction, I would likely do it first because I'm not going to spend a whole lot of time retouching and color correcting a picture that I don't know that I can save, so I'd be tempted to say to do this first. This is a matter of course, just to see if it's going to get you to where you need to be with s image if it's going to bring it around, because if it's not, then you may as well go hunt for another image so well, I usually say that toe last, I'd say shake reduction, you might want to use it first. Cool. So and my question is, where has this filter been all my life? Where? Um ok, another question from the chat rooms jayvee laster mind from minnesota says, does the shake reduction filter pretty much eliminate the need for image stabilizing lenses? Does having image stable a save id, stabilization on mess with the results of the shake reduction filter all really great questions? Thank you so first no, it is not to be used in place of image stabilization invalid image stabilization is absolutely amazing. And depending upon what kind of camera and linds you have, it may be in the body of the camera or maybe in the linen it's my personal opinion, I'd like it in linz because that's, where the action is really occurring so it does not take the place is too great if image stabilization cannot make your image sharp and often times, it can't, but it does help you out a lot, then this may be able to get you there, so they're great to be used, you know, in conjunction with with each other, and so it doesn't take the place of it. Um, what was the last part of his question? Does having image stabilization on mess with the results of the shake reduction filter? No, I wouldn't say so at all. I'd always leave image stabilization on it is on your limbs. Make sure it's turned on it's in your cameras probably turned on automatically that yeah, you needed any help you can get if you're shooting without a tripod, you know, shooting with a tripod, these problems are, as you know, ramp it that without and shooting. Long lenses yeah, you're going to get cameras sake. I'm glad you mentioned that because twenty core bill gate was a great tip last week is like if you're on a tripod, turn it off, turn your image stabilizer off because it really messes with with stuff. And one more thing that I want to mention about kaymer shake is it's not going? Tio radic ate all the motion in your image if this plant flowering plant famous coming down from a tree had the winds been blowing and I got blurred because of wind than this filter would not do as good of a job. So really is on ly for eradicating camera shake so that's you the shooter moving the camera fell? Yeah, how does it compare teo the smart, sharp? And, you know, using the lens blur option? I mean, in the prior versions, it's a much better job, ok, a much better job and far easier uses really it's the first told that we've got that's really analyzing the image to try to discern any kind of pattern of the blur to see which direction you move the camera, and then with that information that can go in and try to get rid of it. So it's really the first tool of its kind that we've had like that there is a trick for saving, trying to save blurry images using the m boss filter that I'll show you all tomorrow in the filters class and it's, similar to this, but not nearly as advance. It was just a fail safe, like it was your one and only thing you could do and photoshopped to try to save a blurry image. But this is really fantastic, and it can taken unusable image and save it again, depending upon what the output for that image is. I would not sell this to an art gallery, right? But it may be good for whatever my purposes are.
