Lightroom - Understanding Clarity, Vibrance and Saturation.

In Lightroom 2 the collection of Basic fixes available for your image includes three Presence sliders that sit together in the Develop module: Clarity, Vibrance and Saturation. This week I'll explain the differences between these three adjustments and how they affect your photos. In each of the screenshots below I have set the slider value to 100 – way more than you would use to fix your image but a setting that will show clearly how the fixes work.


Step 1
Let’s tackle Saturation first. The Saturation slider works similarly to the Saturation slider in Photoshop or any other graphics software. It lets you adjust the saturation of the colors in the image – drag it to the right to brighten and deepen the colors in the photo. If you drag to the left, you remove some of the depth and brightness in the colors and, if you go all the way to -100 you end up with a desaturated or monochrome image.

One of the problems with using the Saturation slider is that it adjusts all the pixels in the image – those where the color is lacking in saturation and those that are already highly saturated. In trying to fix the pixels that need a color boost you can end up shooting some other pixels into right over the edge so the colors tend towards the ridiculous.



Step 2
The Vibrance slider solves some of the problems that you'll encounter when trying to boost color saturation because it is more particular about what it adjusts. With vibrance only the least saturated colors in the image are adjusted and those pixels which are already relatively saturated are adjusted less. The result is that you’ll get a general improvement in the saturation in colors in the image but not to the extent where colors become unrealistically bright. Vibrance also offers some protection for skin tones which makes it a good choice for adding saturation to portraits as it is less likely to over saturate and destroy the subject's skin tones. In many instances you can safely bypass the Saturation slider and adjust Vibrance instead.

Step 3
The Clarity slider affects the contrast in the midtones in the image. It works by increasing some of the edge detail in the midtones giving a general sharpening which adds punch to your photo. Typically you will want to adjust the Clarity of your image in a positive direction using a setting of around 10 to 15. If possible, view your image at 100 percent so that you can see the changes that you’re making to it as you adjust it.

Lightroom: Spot fixing with the Adjustment Brush

One of the exciting new features in Lightroom 2 is the adjustment brush which lets you to make spot fixes to your image in Lightroom. These fixes apply to only the area you select rather than the entire image. This means you can make local adjustments for contrast, saturation, exposure, brightness, clarity and sharpness without having to take the image to Photoshop to do this.

In this post I'll show you how to get started using the adjustment brush in Lightroom. 2


Step 1
Open Lightroom and click the Develop module. Locate the Adjustment Brush and click it to select it. Hold the brush over the image to check its size. The inner circle is the hard part of the brush and the outer circle shows the edge of the feathering. To adjust the brush size use the [ and ] keys or adjust the Size and Feather using the sliders.



Step 2
Select the adjustment to make, such as Brightness or Saturation by clicking its + symbol to increase its value or the – symbol to decrease it. Then start painting on the image to adjust that part of the image. When you start painting the effect onto the image, Lightroom places an identifying marker on the screen. Here I have Brightness selected and the marker is visible.



Step 3
If you don't know where you have painted – and it's often very hard to know exactly - press the O key to view or hide a mask which shows the area you have painted on. If you prefer to, you can display the mask as you work. The mask also appears if you hold your mouse over the marker.

To erase the brush strokes, click the Erase option in the brush area and erase over the area to remove the strokes. To return to painting click brush A which is the default brush and continue to paint over the area. You can also use the brush with the Alt (Option on the Mac) to remove the painted areas rather than switching between the brush and eraser.



Step 4
If the effect is too much or too little you can adjust the intensity of the effect using the slider.


Step 5
If another area of the image requires fixing, click the New option and then repeat the steps to select a fix and then paint it onto that part of the image. Later on you can adjust either of the fixes by first clicking the Adjustment Brush tool to select it and then click on the marker for the area to change – you will see that the word Edit is now highlighted - and you can now adjust the painted area or adjust the amount of the fix.

In a future post I will look at some more advanced functions of the Adjustment Brush.
