Copy and paste
Open the portrait and the two blend images
(multi_01-03) into Affinity Photo, then make
sure you’re in the Photo Persona (top-left
icon). Go to the multi_02 image, then press
Cmd/Ctrl+C to copy it, go to the multi_01
portrait photograph and hit Cmd/Ctrl+V
to paste it in place.
Position another image
Copy in the multi_03 image, then, again,
choose a blend mode (we picked Screen
again). Just like before, use the Move tool to
experiment with positioning until the layer
fits neatly with all of the others. An image
with a bright edge, like the skyline here,
works well for multiple exposure effects.
As well as using images of your own (or
those supplied by us), you could also
download free photographs, like this, from
Pixabay.com. Once more, this is blended
with the Screen blend mode and positioned
to fit in with the rest of the photos. Add any
other shots you like into the mix.
Boost the tones
Once all the images are blended, fine-tune
the positioning until they all work together in
harmony. Finally, click the Create Adjustment
Layer icon in the Layers panel and choose
Curves. Drag the curve line down slightly to
darken the image as shown, and make any
further tonal adjustments you like.
Blend the layer
Go to the Layers panel on the right. Click the
blend mode dropdown at the top and hover
over the different options on the list to see
how they blend the two images together.
The Screen option is ideal for multiple
exposure effects like this, but you may
find a different mode that you prefer.
As well as using blend modes
in combination with layers,
they also feature in several
tools in Affinity Photo. For
instance, the Brush tool lets
you paint in combination
with a blend mode. This
means you can, for example,
paint a colour set to the
Multiply blend mode, so it
gradually gets darker and
darker, resulting in a colour
burning effect. A handy
preview of the blending
effect shows as you hover
the brush cursor over the
canvas, this way you can
predict how it will look
before you start painting.
Grab the Move tool from the toolbar and
click on the corner of the blue bounding box
around the image to resize and reposition
the top layer. Do this until the placement
works with the layer below. You can right-
click during this to choose Transform, if you
decide that you want to flip the image.
