Understanding the Point Tone Curve

From: Lightroom 3 New Features

Video: Understanding the Point Tone Curve

There is a new feature in Lightroom 3 inside of the Develop module in the Tone Curve. This new feature has made many Photoshop enthusiasts really excited and here's why. Well, you'll notice that I have this grayscale here and I'm currently inside of the Tone Curve panel. Well, in this panel what we can do is make what are called Parametric Adjustments. You notice that as I hover over these different areas say, for example, the Highlights, I can then click and drag up or down. Yet there's kind of a safety net. I can't adjust this very drastically.

Understanding the Point Tone Curve

There is a new feature in Lightroom 3 inside of the Develop module in the Tone Curve. This new feature has made many Photoshop enthusiasts really excited and here's why. Well, you'll notice that I have this grayscale here and I'm currently inside of the Tone Curve panel. Well, in this panel what we can do is make what are called Parametric Adjustments. You notice that as I hover over these different areas say, for example, the Highlights, I can then click and drag up or down. Yet there's kind of a safety net. I can't adjust this very drastically.

I can target that area, but again I can't really control it that drastically or that precisely. I also only have these four quadrants: Shadows, Darks, Lights, and then Highlights. Well, there is a new feature which allows us to exit this parametric curve and enter into a point curve. We can do so by simply clicking on this icon here. Now, at first glance, it doesn't look like much, but this Point Curve acts just like Curves in Photoshop. Let me show you what I mean. Well, I will go over the Highlights here and I will click and drag up.

You notice now that I can make really drastic adjustments. I can also click and drag down and do the opposite. The other thing that we can do here is of course use a Target Adjustment tool here. I will click on that tool, hover over the image, simply click, and then I can drag one way or another. As I hover over these different areas, you notice that as I click, I can also set points all across this particular curve and here I am just setting a number of different points to illustrate that what we can do is target one little area. You notice that I'm just controlling this band of color here or tone inside of this grayscale image.

Now, we can of course also use some of these presets. In this case, let's take a look at medium contrast, or we can go to strong contrast. Here just a subtle S curve really boosting the overall contrast. Now we can modify that by modifying these different points. Well, what if you want to remove one of these points, what can you do? Well, if you want to get rid of one of these, simply click and drag it off and then you can remove those points in order to make changes to this curve. Now, in this case we're kind of back to a normal just straight line. We can also do things that are even more intense.

I am going to go ahead and invert this. So I am going to bring my white point down and my black point up. So here, what we have is an inverted view of this image. You can really see how you have that intense control of these different points. Well, if ever you make adjustments that are over the top or too strong or things have just kind of run amok, all that you need to do is to go back to this Point Curve dialog and then here simply click Linear. That will then take things back to normal. Well, how then does point curve and parametric curves relate to each other? Well, if I make an adjustment here, say, for example, bringing this point up inside of my point curve, when I go back to my parametric editing, you'll notice that that same curve is there, just these areas that I can adjust have now been modified to make sense with that particular curve that I've dialed in.

So I can use both of these together in order to come up with the best results. Well, let's take a look at how we can use this on an image and let's do that in the next movie.
