If you have painted in an adjustment to an image that changes multiple sliders, only to find that the overall effect is too much, place your cursor over the Pin for the Adjustment. The icon will change to a double headed arrow. Click -drag left/right on the pin (with the double headed icon) to increase/decrease all of the changes made to all sliders at once (this will be a relative change). This can be very useful when you think that the overall effect is what you want, but it’s just a bit too strong.
(For those of you that use Photoshop, you might want to think of this technique as similar to lowering the opacity of a layer – but I don’t want to confuse the issue if that analogy doesn’t work for you!)
