HOWTO | Create a layered, multiple-exposure ima ge
1 Repair tool
We need a plain background. This lovely picture of the sea has a killer whale leaping uninvited into shot, but we can remove the interloper using the Repair tool, which can also remove spots, dust, scratches and former political allies. You can change the brush’s size using the slider at the top-left.
2 Brush it away
With a suitable size of brush selected, paint over the unwanted object. If it’s small, like a spot on a model’s face, use a quick dab with a brush the same size as the mark. We’ll have to paint out our whale with multiple strokes using a medium-sized brush. Going over the edges is fine.
3 Stages of erasure
The Repair tool looks at nearby pixels to decide what to replace the unwanted object with. When removing a large object, painting in stages gave us a better result than erasing in one go. With your desired result, paint over any remnants with the Repair tool, blending the repair in so it looks natural.
4 Choose images
Pick two images to blend; one with a strong shape to it, the other something softer. To select this kite, we used Paint Selection to draw over its background. Pixelmator smartly selected the right areas – we inverted this, then copied and pasted it onto our background as a new layer.
