Ever heard of the TAT? Ever wondered what that little circle that looks like a target was?
Well, the TAT is the Target Adjustment Tool and if you never tried it, you are missing something. It is a way to visually adjust some development settings in Adobe Lightroom.
You just have to click on that little circular target thing to activate it. You will see your cursor changing to the same symbol with up and down arrows. The way to use it is to go to the area of the photo you wish to modify, click and hold your mouse button and move upward and downward to adjust.
You can do that with 5 settings in the development module: Tone Curve, Hue, Saturation, Luminance and Grays.
For the Tone Curve, you can go to a part you wish to lighten on your photo and just move the cursor upward to see the result. It's a good way to start, but I prefer to do the fine tuning on the Curve itself at the end.
For the Hue, Saturation and Luminance, it is very helpful. For example, you want to darken the sky. Your first move might be to go to the Luminance and bring down the Blue slider. But the sky is not pure blue, you usually have some Aqua in it. If you bring only the Blue slider down, the result might be strange in some spots where there is more Aqua. You will probably get artifacts too. Using the TAT, Lightroom will bring down both sliders as needed. You might end up with -12 Blue and -3 Aqua, and the result will look better. It is even more useful with the skin tones.
I like it a lot in Black and White conversion too. It's easy to go to a part of the picture you want to lighten or darken and play with the TAT. You can watch at the same time which color is brought up or down and do your fine tuning afterward.
