So let's move on to another new feature that is a little bit buried hasn't gotten a whole lot of press, but let me tell you it's a fantastic thing you may have noticed that any time you create a levels or a curves adjustment or adjustment layers, I liked it because I don't like my levels or curves to actually apply to my original image. I like to put it in his own little space and it's only a er so that I can lower layer opacity if I want to to back off with my mother the change that I made using levels occurs throw it away if I don't like it okay, so there is an auto button in both of those adjustments and the math behind that auto button has been completely rewritten toe work a whole lot better and what we're going to do is we're going to take a look at clicking the auto button in both levels and curves in cia six right next to see us five in the difference is pretty dramatic, so what that means is if you don't want to mess with learning how to use levels or occurs but you want the b...
enefits of those tools, create the adjustment, then this click the auto button and let photoshopped do what it thinks needs to be done to your image ok theon all that has been around since forever however, the math behind it has completely changed so let's open up an image and then we'll talk about how that math has changed now this superhero I really expect everybody to know and I'm gonna be disappointed with you guys if you can't figure out who this is anybody? Anybody the invisible man. Okay, so give me just a little second here, tio arrange my work top here so that you can see six in c s five at the same time. So since I've got the application frame turned on that we looked at this morning it lets me move my whole four top environment around so it's going to be easy for me. Teo, open up, see us five u c a six side by side so you can actually see here we go make him a little bit bigger. Okay, so let's do and levels adjustment in both of these documents. Okay, so I'll start out in cia six here. So the way I like to create adjustment layers and we talked about adjustment layers a little bit earlier this morning is your way of saying hey photoshopped this next change or adjustment I'm gonna make please if you don't mind, put it on its own layer so it doesn't mess up or touch anything else it's kind like people who like their food separate on the plate don't touch anything so the way I like to create adjustment layer just by using the shortcut meaning at the bottom of the layers panel anil xena's you can see it it's a little half black, half my circle ok, and when you click that many, you get a pop it many that shows you all the different adjustment layers you could make in photo shop. Well, you can also simply use the layer many to create a justin layers, okay, so you can choose layer new adjustment layer and it's the same list that you get at the bottom of your layers panel all right, I think it's faster diesel, but the bottom layers panel nevertheless we're going to choose levels and photo shop is going to ask you what you like to name it, we'll just let it roll with levels one and and see a six year properties panel opens I have made it larger earlier to demonstrate that you could do that, but I'm going to go ahead and make it smaller again so we can see the invisible man so we can see the invisible man all right, fine, we'll diskette it out of the way, okay, so here we have our levels adjustment and in the new properties panel here's your auto button right here, so if we simply give that a click the shop is going to do what it thinks it needs. Teo. Teo, correct the lighting in your image and you can see the difference between the before and after. If I toggle the visibility I often on next to that adjustment later, see how we got an adjustment layer or document now, right here. Okay, so I turned that off. That's the original turning on that's the new auto adjustment. Now, what the heck did a deep math that changed? And I'm gonna command click this button so you can see it actually it's an option click if you option, click or also click on the pc, the ottoman, then you can see see the different algorithms or mathematical formulas that photo shop uses for these auto buttons. Now. In previous versions, this math was being used enhanced per channel contrast, that simply means that photoshopped adjusted each channel individually. And what are your channels? You've got a channel for red. You've got a channel for green. You've got a channel for blue because those were the three colors that your cameras capturing, all right, so in the old days, see us five in previous photo shop was using this method and it was going into each channel individually, and it was lightning the highlights a little bit in darkening the shadows a little bit. So you're highlights, or your lightest parts of your image and your shadows or your darkest parts of your image. So it was doing a little bit of lightning, a little bit of darkening across the board, whether that really needed to be done in that particular channel or not. Okay, so it's kind of all or nothing situation there you see a six adobe changed the math that that auto button uses, and now it uses what's called enhanced brightness and contrast, and that simply means that photo shop is going to analyze. Your image is going to really look at those different channels and it's on ly gonna lighten the highlights or dark and shadow, as if that particular tail needs it. Theoretically doing a much better job of correcting your image by you just click in the auto button and not having to really dig into those adjustments. Tio, use them manually. Ok, so that's the change they made so let's, take a look and what that difference looks like and see us five okay, so what pop over here to see us five we've got the same little adjustment layer shortcut menu at the bottom of your layers, paying all the half black, half white circle, and we're going to choose levels see how insidious five thie levels adjustment settings actually appear in the adjustments panel? They happen in the properties panel and see a six ok, so now let's, go ahead and click our auto button when you see the difference. Look at the color it's little bit hard to see on this screen, but there was a color shift over here that did not happen in c s six ok, we've got a little bit more detail showing in his tie area. I can actually see diagonal patterns on the time that I cannot see over here by clicking the auto button and see us five so it's fairly subtle, but if you do this on your images at home and I wish you guys could see this screen right here because it's a big difference, I think you're going to have much better luck. I mean, much happier with the using those auto, but isn't cia six so that's a little thing, but how useful is that? You know, when you're short on time that maybe all your image needs just click that all of it, and ok, so let's, take a look at that on another image, and again, I'm just pressing command, debbie, you're controlled of you on a pc to close the window. And then I'm clicking the first letter of the button I want to trigger to trigger that button rather than massing all the way to it because let's face it. I'm sure all you'll have what forty five inch screens at home? You know that's. A lot of mousing mess way over there that box. Ok, so now let's, open up another image. Let's, look at curves. Okay, so we'll open up anybody toilet paper, man, can you even believe there's all these images on I stock photo when I was down letting all these things weeks ago, whenever it was I was howling, I was laughing and jay would come into the studio. My husband jay, what is going on? Heading and I was showing him all these images and it was really fun toilet paper, man, I guess you could call him bathroom, man, because he's got a plunger and a scrubbing brush too, but nevertheless let's, take a look at the curves. Auto button. Okay, so same kind of math instead of enhanced per channel contrast photo shop is using enhanced brightness and contrast math instead in unless you're one of the engineers that knows what's behind that. I mean, really, who cares? It does a better job now been eesti, I think so now let's create go ahead and dock my properties people again let's go ahead and created curves adjustment layer will do exactly the same way that we did the levels adjustment layer will click the half black half white circle at the bottom of the layers panel cheese curves from or their resulting menu gland just click the auto button give it one click and now I'm gonna collapse my properties painted by clicking the right facing triangles towards a top okay so here's our before we turn off the visibility ion the adjustment layer that photo shot made for me so there's our before there's are after so the image looks a little bit warmer than it did before a little bit more contrast so now let's go back in the c s five and see what we get over here let me collapse my adjustments panel now this is where really fun begins when you start using two programs so ever and see us fire remember how I said you can double click the free area next to a panel to collapse or expand and then over and see a six you double click the tab itself so going back and forth between the programs can be a little exciting all right? So here we are in serious five we're going to click our half black half white circle once again choose curves from the resulting menu and click the auto button ok, now let me expand my layers panel again so we can see the visibility I in order to toggle it often on so there's our before and there's are after so if you compare the two images I don't know about y'all but to me the one on the right looks a heck of a lot better than the one on the left ok? So that's the new math behind the auto buttons and the curves and levels adjustments any questions on that actually got one more image I can show you so you know, using the stock images, you're not going to see that much of a change because these images are amazing anyway or else they wouldn't be available for sale a stock images right? So let's take a look at this stuff on a regular old image it's only clothes these guys and then we'll take some questions on and if you have any so here we are gonna open up an image I shot in budapest sh in december got to dio river cruz teaching trip and that was a lot of fun. You actually come with me sometime so this is shot I got and I'll open it up and see us five as well so we can see the difference all right? So go ahead and throw away the layers that I created simply by activating them, impressing the delete key to throw away layers so let's have a go with curves so we'll click the half black half white circle at the bottom of the layers panel cheese curves click the auto button and if I toggle my visibility I off and on I have a better image more contrast come over and do it to see us five I'll throw away the layers that I already created create our curves adjustment lair click the auto button and there's the difference more contrast in the image on the right the left one still pretty flat now another little bonus tip for this is this particular shot then I'll go home and hide see us five for a moment there we go make our screen begin or our environment big again so this was not the first image that I shot and I'll actually go into full screen moments you can see this a little bit better so this is a tip with him this little movie in that this synagogue that I was shooting is the great synagogue in budapest the largest synagogue I think in europe and the thing was so huge that I couldn't actually capture it all with my camera okay, so what I did was I looked at the shot and I got the pieces in parts of the building that were important to me okay, so this is just a tiny little photography tip for you here's the original shot that I took and it is incredibly crappy see the building is this too big? You can't capture it? So what I did was I got close to something that was important to me, which was the monument here, and I positioned myself so I could catch what I thought was the prettiest part of the synagogue in the background, which was the stained glass mosaic in the background. So it's, just a tiny little vacation photography tip for you. If you're capturing anything, especially in europe, where things are really, really big in ancient, then find a spot to focus on instead of trying to capture the whole thing so you don't end up with a crappy shot like that. So there's the difference between the original image and clicking the auto button and curves, and again that maybe all your image so do you take advantage and try on those the auto ben's in both levels and curves? Any questions on that part? We do, we dio so from trish to ninety seven does this eliminate the need to go into the rgb channels curbs by using automatic? Theoretically, yes, it just depends on the image you know you can let photoshopped have a go by using the auto button, seeing what you think about the resulting image, if it looks good, then you're done, but if it may not always do the trick to fix every single image, so on some images they may need a little bit more massaging plan. Others think and photo tea from new jersey ask which one to use more often curs or levels levels on the level coming girl sometimes except when I'm leaping tio get a guitar picks countries ok, another question well, from phil you d g from the u k, so would you suggest using auto as a starting point? Sure, why not? Sounds like it. Yeah, I mean, the whole point with a lot of the stuff I'm showing uses a fast way to get from point a to b b may not be your end point. You may need to go further than that, but have a go and see if this fixes the problem and if it does, you're done. You can go on to your next project or you can step into the great outside away from your computer so there's give it a shot see if it works. If it doesn't, they can go back to your tried and true methods of current in color and lining by adjusting the levels and individual channels if their history ums are different enough, which is all covered in the c s five intensive course for doing emanuel curves adjustment, but why not try auto first to see what happens
