across the bay. Find it in the “Filter” menu, and prepare for a
surprise, as it looks nothing like the filters we’re used to. It places
a new light source, enabling you to choose the parameters that
make it up. We’ve only got the sky selected here, so brightening
one corner and making the light bright blue gives the impression
of a sunlit summer sky, rather than the overcast, windy, verging-
on-cold conditions we shot the photo in. Again, the before and
after split view is useful if you want to see exactly what you’ve
changed. The vertical terminator can be slid left and right to
cover and uncover the image as you want [Image C].6
EXPORT
Once you’ve finished in the Photo Persona, save your file
as a layered .afphoto file, to preserve it in a state you can
return to later for further editing. To create a small but highly
detailed file for sharing online, you can switch to the Export
Persona, which has a host of options. Export is based on slices—
you can carve an enormous composite image up and export parts
of it as individual files. It also preserves the layer structure prior
to export, so you can export individual layers as files [Image D].
>> There’s a “Slice” tool on the left you can use to select
areas of your image to export as files, if that’s what you want.
To export layers, select one in the “Layers” panel, and chooseD“Create Slice.” There’s an “Export Options” panel at the
top-right in which you can set the file type, bit depth,
and compression level of the files you’re creating. When
you’ve finished, open the “Slices” panel and either click
“Export Slices (N),” where N is the number of slices to
export all selected slices, or do it one at a time.
>> You can export a single file from the Photo Persona
using “File > Export.” You get a choice of file types,
resampling methods, and compression ratios, but the
whole Slices thing is no longer a complication.CThe Develop Persona can be used on an individual layer
if you find it a good way to edit. While we recommend
shooting raw images in your camera and treating
Affinity (or Lightroom/Adobe Camera Raw) as a digital
darkroom, Develop can do a lot with processed data.
Split your image into layers, using something like the
“Flood Select” tool to perhaps carve the sky from the
landscape, then make sure that, while both are visible,
only one is selected in the “Layers” palette on the right
of the Photo Persona. Click the button at the top-left
that takes you to Develop, and Affinity remembers
where the dividing line is. Any adjustments you make
in Develop only apply to the layer you had selected.LAYERED DEVELOPMENTS
