How to Apply Selective Adjustments in Lightroom

A Post-production workflow can be complex, if we want to do the job to a professional standard, making it essential to move past the basic elements offered by software like Lightroom, if we intend to excel as professional designers.

But how can we introduce more elements to each image for a custom look, beyond using sliders? Advanced features in form of tools, such as Graduated Filter, Radial Filter and Adjustment Brush, come to the rescue, provided by Lightroom to dedicated users who know what they want. With the help of them, we do selective adjustments in Lightroom.

Let’s explore in detail every single option designed for selective adjustments in Lightroom, and enjoy the many things they can give us through the process.

Graduated Filter Tool

Prior to talking about the Graduated Filter tool in detail, let’s picture ourselves in a post-production scenario, where we need to bring out more detail in a picture that looks similar to the image below.

01_selective

Notice the two main elements in the scene (the subject and the background) and define the area where you want the adjustment to be applied, as well as the parameters needed.

02_selective

For instance, I may decide that this subject requires a bit more Clarity in order to make the model appear closer to the camera, and that I should increase Contrast a little bit – but I don’t need those adjustments to be applied to every single area of my scene. This is where the Graduated Filter tool comes in handy.

By selecting the Graduated Filter tool, you will be applying changes to a selected rectangular area, which will have a fading effect near the edges of the area where it is applied, making it blend neatly with the elements around the adjusted area.

Select the adjustments you want to apply to your image, and click then at one point while dragging with the mouse at another point. That will create an application area, which you will notice, if you enable ‘Show Selected Mask Overlay’, is likely to affect the area to the left of the selection you made as well.

03_selective

After hitting ‘Done’, you can view the adjustments you applied, and if you need to correct any parameter, simply select the tool again, click on the tiny gray button that shows up on the main Develop area, and correct the parameters shown in the slider area.

You can use the Before/After mode to compare the changes applied to the image.

04_selective

Radial Filter tool

This tool works in a very similar way to its ‘brother’, the Graduated Filter tool, although you have much more control over the selection made, and the applied changes won’t affect the selected area, but rather everything else that is not included in your selection.

05_selective

Of course, these settings can be changed, if you go to the bottom of the tool panel and hit ‘Invert Mask’.

06_selective

The Radial Filter tool is likely to become a part of your post-production routine by giving you the liberty of adjusting nearly every single aspect of your image, while discarding everything else that does not needed to be adjusted.

The effects made with this tool are often soft, since you will have exact control over which area you want the parameters to cover, rather than setting an overall value.

Adjustment Brush tool

And what if you need even more freedom to adjust your image? What if I tell you that you can just click on tiny selected areas and apply changes, exactly like you do it inside Photoshop?

07_selective

The Adjustment Brush tool is intended for extremely specific purposes, such as bringing detail/giving tint/correcting values of tiny, hard to reach areas where precision is a must.

This tool is often overlooked by users, who consider it useful only for ‘beauty jobs’, but the Adjustment Brush tool can do much more. With the right set of presets, you can simulate sunlight in your post-production project!

08_selective

As you can see, the sky is the limit with these advanced features. Designers work hard in order to provide quality products for these kinds of features, such as brush presets, but the truth is that brushes can work with the previously mentioned tools as well, making your post-production experience much broader.

The only thing Lightroom will demand from you is that you practice to be able to use such advanced retouching tools; but in the end, the effort will be worth it, as you take the first steps on the path of professional photography.

Day 9: What is Lasso Tool in Photoshop

There are times when we need to select things out in an image so that we can only edit the selected part. For those purpose, we have several dedicated tools in Photoshop, and one of them is the Lasso Tool in Photoshop.

Before we begin with lasso Tool, let’s understand selection in Photoshop. Selection is like a lock. When we select any part in image, only that part gets edited. Let’s understand this with the help of Fig. 1. In that image, the dome is selected as you can see marching ants surrounds the dome. So whatever I do now, be it increasing brightness, decreasing contrast or anything, it’ll only affect the dome.

Now there are numerous tools present in Photoshop for this kind of selection. One among them in Lasso Tool.

Photoshop provides three variants of Lasso Tool. Each one performs same function but being executed differently. These three are:

  1. Lasso Tool
  2. Polygonal Lasso Tool
  3. Magnetic Lasso Tool

Fig. 2 will show you where to find them. You can also press Shift+L again and again to activate selection.

Fig. 2

Now I am going to explain you each of them one by one. They all are very much similar. Let’s start with the first one i.e. Lasso Tool.

Lasso Tool

This tool is like a freehand selection. You just draw on the screen and Photoshop will automatically select the area as soon as you leave the mouse button.

Fig. 3

I am sorry for the not so accurate drawing or selection. I am not good at drawing.

Believe you, you’re never going to use this tool. The other two kinds of Lasso tool may be used by you in future. The reason is that we have other tools that perform same action but with better result in lesser time. There’s nothing there to explain in Lasso Tool.

Let’s move to the Polygonal Lasso Tool.

Polygonal Lasso Tool

This tool is basically present for straight edges. You activate this tool just by clicking anywhere on the image, and wherever you take your mouse cursor, the tool will go with you. To create an edge, you need to click on the point. Fig. 4 will explain things better.

Fig. 4

Are you seeing a gray color line near the edges of the building? They are made with the help of polygonal lasso tool.

I intentionally placed the selection slightly off the edges so that you could see properly.

Let’s understand how it works. I started the selection from the viewer’s left side. You could see the beginning of the selection in Fig. 4. Now I all needed to do is to click on the point where I want my selection to take different path or bend. You are seeing 5 corners in the above selection which means that I clicked on five points.

Let’s move to Magnetic Lasso Tool.

Magnetic Lasso Tool

This tool works like a magic. It automatically detects edges and tries to align itself according to the edges.

Let’s see it in action.

Fig. 5

I know that the result is not perfect, the I appreciate the try. Photoshop does a wonderful job there.

Basically Photoshop looks for drastic contrasts between adjacent pixels and whenever Photoshop finds it, it’ll know there’s an edge present.

So how to handle this tool? The answer is you don’t. It’ll handle itself. All you need to do is to keep the mouse as close as to the edge, and let the Magnetic Lasso Tool performs the rest of work for you.

Now let’s talk about the option panel that comes with the Lasso Tool.

Fig. 6

A. You have seen these four boxes in Marquee Tool’s chapter. I am going to write same for your reference.

  • New Selection: This function provides you a new selection. Let’s assume that you have selected a custom area in your image and then you don’t like the selection, and want to select a new selection that is going to override the existing selection. This mode is best to do these kind of things. In short you if you deselect a selection by pressing Ctrl+D/Cmd+D and then select a new area, the result would be same.
  • Add to Selection: I bet 99% of users use this mode. Let’s say you have selected an area and you also want to select another area but don’t want to deselect the existing area. Then, my friends, this selection is perfect for you. Lot of tricky selections can easily be done by this selection. When this mode is on, you’ll see a + sign near your mouse cursor.
  • Subtract from the Selection: As name says it subtracts the selection. Basically it is just opposite of “add to selection”. You’ll see a sign just below the cursor.
  • Intersect with Selection: Suppose you have selected an area A and also selected an area B. A small part of area B lies inside the area A. Then only that small part will be selected. Basically the overlapped are will be selected in this mode. By pressing this you can see a small multiplication (x) bar at the bottom of your cursor.

B. Feather: It softens the selection. It helps a lot when you are creating vignette effect to your photo. You can learn more about it here.

C. Anti-Alias: Photoshop smooths out the color transition between the pixels around the edges of your selection and the pixels in the background.

D. Refine Edge: You have a whole tutorial dedicated to this feature. It is probably one of the mightiest feature in Photoshop.

I hope that you found this tutorial helpful.
