Subtitles of the Movie

þÿ [00:00:00.0] Alright now, this photograph ought to be familiar to you if you have looked at all the movies in this tutorial. This is the photograph of Deidre and Sarah playing with the puppy at the campsite. [00:00:11.0] And we showed to you in a previous movie that was geared more towards Photoshop 7 how to create depth of field. And it works, but it is a bit imperfect and you can get a more accurate and more believable result with the lens blur tool than you can with any process available to you in Photoshop 7. [00:00:29.0] So let us take a look at how to do that. Now the one thing that you have to consider in this photograph that we didn t have in the photograph previously of the lonely country road is you have got a vertical plain to deal with. [00:00:40.0] We're using two dimensional tools to render effects on a three dimensional perception and things get a little bit twisted. So you have got to pay attention to the vertical plain and then obviously the vertical plain in this image is Sarah and Deidre and the puppy. [00:00:55.0] We have got to get all of them to be in the focus and everything behind them to be in a gradual depth of field. So let us take a look at how to do that. Now the one way to do it and I am going to do this very sloppily because this is only for demonstration purposes. [00:01:07.0] We are going to have to make a selection and under normal circumstances we would get real close on this and really get very anal on how to draw all this out, but I am going to kind of whip through this very quickly. [00:01:19.0] It's going to look weird when we get it done but at least you will know how to do it so that when you are going to do it for real you are going to take your time with your selection which is not what we really care about in this lesson. [00:01:31.0] Right there is our selection and we go up here to inverse, go to our layer tab, right click on background [00:01:44.0] and click on layer via copy which places that selection by itself above the background layer. We are going to disable the background layer [00:01:57.0] and go to our channels tab and again hit Q to bring up the quick mask. You should know how to do this now because you have seen it before. [00:02:09.0] We go over here and pick up the gradient tool and now here we have got to do things a little bit different. Now the point of focus on this is right here and this is in the same vertical plain as the two girls and the dog. [00:02:26.0] So we want our point of focus to be right here and we want to gradually lose its focus as a normal depth of field would do from here back. Now over here we have dirt. [00:02:38.0] Now the vertical plain here is different from the vertical plain here. Yet in the two dimensional world that we're effecting this in it's in about the same area vertically on the image. [00:02:48.0] But if we went to a straight vertical application on the gradient it would look weird. It just wouldn't look right. So, we are going to slant this just a little bit to take this out of focus and yet leave this in. [00:03:00.0] So we grab our gradient tool and we are going to start at the bottom or near the bottom we go straight up but we are going to tilt this a little bit. [00:03:11.0] And then we hit Q to establish our selection we invert it; go filter - blur - lens blur [00:03:27.0] and play with the radius to make it look right. We do not want it to be too much. We want it to look real. We want it to look realistic. [00:03:43.0] And our point in doing this is to bring focus to the subject which is here. This image is a bit crowded. You know we have got the coolers here, [00:03:53.0] the picnic table, a little bit of business going on here. We want to soften all of that. Make that less distracting and focus the attention right here. So we are going to adjust this towards a believable depth field [00:04:05.0] but yet still there and we hit OK. And we go deselect and then we come over here [00:04:22.0] and we bring back that and we see this is in focus but yet we have a gradual depth of field application from here to here and look down here. [00:04:32.0] It is out of focus a little bit, which is natural, and then the focus becomes more pronounced the further up in the image you go. That is a much better result on the depth of field simulation that we had in the previous lesson using this photograph. [00:04:47.0] Now one other thing you might want to do and this has nothing to do with blur tool but in order to continue to focus attention on that you might go up here and I am not going to do a layer, [00:04:57.0] I am going to do levels and maybe just bring down, let s add some darkness, bring down the gamma on the background hit OK. [00:05:13.0] And that really brings out your attention on the girls. Alright, let us take a look at that on the history tab. [00:05:23.0] That is before and this is after, before and after. Now that is a much better photograph of the girls. Yet it looks believable. We have got believable depth of field here. [00:05:39.0] The photograph is, I think, vastly improved. And one other thing you can do and again we are getting anal but you know this is a lesson on how to make your photographs look really good; I'd go up here and add some sharpening to the foreground, [00:05:53.0] not much, you know you don't have to go nuts, just enough to kind of it make it pop and here we go. That is a great result. And the other thing I would do, let s see now, [00:06:07.0] adjustments - curves, and take some of the blue out of here. We have got too much blue in it, warm that up some. And then voilà! We are all done; great photograph, huh? [00:06:23.0]
