Lightroom TAT

October 04, 2011  •  Leave a Comment

Adobe Lightroom is a program that catalogs and edits raw image files from almost every camera made capable of generating raw files. Amongst its many attributes one of my favourites is the TAT (targeted adjustment tool). The TAT can be used to target adjustments in the Tone Curve, HSL and B&W panels. 

The TAT tool is identified by the red circles in the Tone Curve and HSL panels below.  Below the image, in the tool bar, the "Done" button is also circled.  You click on a TAT tool to activate, select the area you wish to adjust, click and drag the mouse up or down, and click the Done button to deactivate the tool.

Let's start with an example of using the TAT to make a tonal adjustment to an image of an eagle.  

In this image of the eagle I exposed to hold the blues in the sky and this resulted in the eagles breast being significantly under-exposed.  I am going to use the Tone Curve panel TAT to lighten the tones on the eagle breast by clicking and then dragging upward.

You can see the results of this in the before and after snapshots below.  Lightroom has managed to lighten the brown tones in the breast without modifying the background blue tones.   Don't forget to click the "Done" button.

Using the TAT tool can also be very effective in conjunction with the HSL controls.  In the following example I have used the HSL TAT tool to lower the saturation of the skin.

Try the TAT tool in the B&W panel as well.  This is where it might be the most useful as you change the gray tone for different colours in the image.

You can find out more about TAT in a video at the Luminous Landscape.
