Tablet-based editing software like Snapspeed and Perfectly Clear 3 lets you quickly fix images anywhere
Make targeted adjustments
Nik software is known for its control points—when you add a dot to your image, it automatically creates a mask to target the area you want to affect. In Snapseed, tap Selective Adjust to start. Select the radius of your area by using the pinch gesture. The software shows your mask in the form of a red overlay as you resize the radius. When the mask is set, tap and drag up or down to choose to adjust Brightness, Contrast, or Saturation. Then drag left or right to decrease or increase the effect. Make one control point to darken and add saturation to the sky, and add another one to increase contrast and saturation in the ground. Then duplicate that control point three times to add the effect to the whole bottom part of the image. Hit Apply to accept the changes.
