Adjustments, Liquify & Clone

Change colours, blur, sharpen and add effects to a layer, push paint around with Liquify, or copy one part of a painting onto another with Clone. Everything here lives under the wand in the top bar.

The adjustments

Tap Adjustments (the wand) and pick one. Adjustments change the active layer, or only the selection if there is one.

Changing the amount

  • Most adjustments have one amount: slide left or right on the canvas to set it. A large percentage shows the value (Posterise shows the number of levels).
  • Hue, saturation, brightness, Colour balance and Curves use sliders and a graph in their panel. Colour balance has Shadows, Midtones and Highlights, with Keep brightness; Curves has a curve for Master, Red, Green and Blue.
  • Motion blur: drag on the canvas in the direction of the movement.
  • Perspective blur and Chromatic aberration have a centre point you can drag on the canvas.

Some adjustments have more settings in their panel:

  • Gradient map
    The gradient: tap it to add a colour stop, and pick each stop's colour.
  • Motion blur
    Amount and Angle.
  • Perspective blur
    Positional or Directional (with an Angle).
  • Noise
    Clouds, Billows or Ridges; Scale, Octaves, Turbulence and Colour noise.
  • Bloom
    Transition, Size and Burn.
  • Glitch
    Artifact, Wave, Signal or Diverge, and Shuffle for a new pattern.
  • Halftone
    Full colour, Screen print or Newspaper, and the Dot size.
  • Chromatic aberration
    Perspective (with Falloff) or Displace (with an Angle).
  • Vignette
    Size and Softness.

The bar at the bottom has undo for your changes inside the adjustment, Reset, an eye button to hold for a look at the original, Cancel and Apply. Once applied, the whole adjustment is one undo step.

Layer or Pencil

Each adjustment has two modes, Layer and Pencil, at the top of the Adjustments panel and in the bar at the bottom:

  • Layer: adjust the whole layer or selection.
  • Pencil: paint the adjustment in with your current brush, only where you want it. Blur a background, brighten a highlight or add noise to one area.

Liquify

Liquify moves paint around as if it were wet, without painting anything new. Pick Liquify from Adjustments, choose a mode and brush over the layer.

  • Push
    Push the paint along with your stroke.
  • Twirl right, Twirl left
    Twist the paint clockwise or anticlockwise.
  • Pinch
    Pull the paint in towards the brush centre.
  • Expand
    Push the paint out from the brush centre.
  • Crystals
    Break the paint into shards.
  • Edge
    Pull the paint towards a line along your stroke.
  • Reconstruct
    Gradually undo the distortion under the brush.
  • Adjust
    Move the distortion you've already made to a new spot.

Push and Adjust follow your movement. The other modes keep working while you hold the brush still, so the longer you hold, the stronger the effect.

Liquify settings

  • Size: how big the Liquify brush is.
  • Pressure: how strong it is. Apple Pencil pressure adds to it.
  • Distortion: adds randomness, for a rougher, more natural effect.
  • Momentum: keeps the effect going for a moment (up to a second and a half) after you lift.

CrowDraw remembers these settings. The bar has Undo, Redo, Reset (start again from the original), Cancel and Apply.

Clone

Clone paints with a copy of another part of your artwork, for repeating texture or covering a mistake. Pick Clone from Adjustments, drag the circle onto the area you want to copy from, then paint somewhere else. The source moves with your brush. Clone uses your current Paint brush, so a soft brush blends and a textured brush clones with texture. Tap Done when you finish.
