Watch video: Use Macros in Affinity Photo
Some image effects take mere seconds to create, but it’s usually those that require a little more work that are all the more rewarding for it. In this project we’ll look at how to transform a portrait into a series of striking geometric shapes.
Unfortunately we can’t just run a filter over the image; we have to create each individual polygon shape. This makes the overall impression completely unique, though, rather than the generic look you often see when filters are used.
Each triangular shape in the face and hair here has to be plotted out by hand, which will take time and patience. Thankfully there is a way we can speed up the process.
Macros are a handy Affinity Photo feature that enable us to record a set of tasks (much like Actions in Photoshop CC). This means that we can make a Macro for a repetitive sequence of edits, then apply the sequence again with a single click. We begin by making a triangle with the Pen Tool, then blur the area and add an inner glow effect. Each step we make is recorded in the Macro. Once done, we can use the Pen tool to move the triangle into a different position and then hit play on our Macro to repeat the sequence.
It might take an hour to cover the face, but it’s a nice mindful task that can easily be done while watching TV or listening to a podcast, and the angular results are worth the effort.
01 Make a triangle
Open the portrait and grab the Pen tool. Click four times to make a triangle over the cheek. Go to the Fill box in the options and choose any color to fill. Double-click the layer name and call it ‘pen shape.’ Go to Window > Studio > Macro and hit the Record button.
02 Blur the area
Hold Cmd/Ctrl and click on the shape layer to load a selection, then click on the background layer and hit Cmd/Ctrl + J to copy the selection to a new layer. Go to Arrange>Move to Front, then rename the layer ‘triangle.’ Go to Filter > Blur > Average.
03 Finish recording the macro
Click the fx button in the Layers panel and pick Inner Glow. Set blend mode to Multiply, choose a grey colour and set Opacity to 20%, Radius 5px, Intensity to 0, hit OK. Press Cmd/Ctrl + D to deselect, click on the Pen Shape layer. Press the stop button in the Macro panel.
04 Reposition the shape
Grab the Node tool from the toolbar. Click on one point of the triangle and drag it to another position, then hit the play button in the Macro panel to repeat the process to create a second triangle. Keep making triangles this way to build up the polygon effect.
05 Build it up
Plot triangles to cover the subject, using the Macro and Node tool. Try to keep triangles in areas of similar color. Use larger triangles for smooth areas like the cheeks and smaller ones for details like eyes. Each one should meet at the corner with the one beside it.
06 Finish it off
Cover the whole subject, then make a few more shapes for the background. Once done, finish off by boosting the colors and the contrast. Add a HSL Adjustment and boost the saturation, then use a Brightness and or Contrast adjustment to increase contrast.
