Whenever you apply an adjustment to a photo in Polarr you're presented with a slider to control it. This slider shows up when you do things like make a global adjustment or smooth skin tones. But here's a pro tip for mobile users wanted to make adjustments even faster: use the adjustment pad itself.
In the image above you'll notice we're in the Global Adjustments panel. We've tapped the Color icon to bring up the four squares for Temperature, Tint, Vibrance, and Saturation controls. Those squares are what we call the adjustment pads.
You already know that you can tap the adjustment pad to bring up a slider onscreen. That slider can then be manipulated in order to increase or decrease the value for the related adjustments. But you can also just leave your finger on the adjustment pad itself and slide up or down to make the same change, without bringing up the slider.
The video below shows the difference between the adjustment pad and sliders.
