FEBRUARY 2020 MACWORLD 81Use Contrast to help images pop by creating
a greater distinction between lights and darks.
Tint, and Warmth—Saturation was already
present—it can be difficult to get the right
tone on your images when you’re trying to
adjust for natural or artificial lighting.
Photos in macOS still offers more robust
adjustment tools, especially in its White
Balance section.
One missing piece are the black and
white controls, still available in macOS,
which let you switch a picture from color to
grayscale. However, you can use the
Mono, Silvertone, and Noir filters to apply
a conversion, and then use the editing
controls to tweak the tonal shape.
CROP AND STRAIGHTEN IN
MULTIPLE DIMENSIONS
You might think it peculiar that I am
jumping up and down—and side to side—
about cropping, but the update in cropping
controls and automatic correction
dramatically improves how you can correct
a shot or make artistic modifications within
the Photos app.
Previously, you just had cropping
edges and corners, a rotation dial, and
the proportions button (still present, but
improved) to choose cropping ratios.
Now, there are three adjustment tools (see
images on next page). It helps to visualize
an image in this mode as being a real
photo you hold in your hands that you can
move around. The tools are:
> Standard rotation (icon at left) is the
familiar rotation around the axis as if the
photo is held flat in front of you and you
turn it from a car’s steering wheel.
> Tilt forward/backwards (middle icon)
treats the photo as if you’re tilting it toward
you at the top with the bottom nearly
anchored, with the perspective warping as
you do (negative slider), or toward you
from the bottom with the top mostly
anchored (positive slider).
> Tilt left/right (icon at right) tilts the
image with perspective towards you from
the left with the right loosely anchored
(negative slider) or toward you from the
right with the left more firmly in place
