Guided

Upright

controls

Thisgives you a degree

of manual control over

perspective corrections, and

it’s helpful when the auto

Upright buttons fail. We

simply grab the Guided

Upright tool from the

Transform panel then drag

guide lines through the

image to correct horizontals

and verticals.

15

Batch-applyUpright

settings

There are two ways to apply Upright

to an entire set. To begin, correct one

image then select the others and hit

the Sync button. You’ll see two options

‘Upright Mode’ and ‘Upright Transforms’.

Mode analyses and fixes each image as

an individual, and Transforms applies the

exact adjustment to all – this is the better

option for batch-processing photos that

need identical tweaks, like a timelapse.

16

Preserveyour settings

When you apply any automatic

Upright correction like Auto, Level or Full

the command will by default cancel any

previous manual-perspective corrections

you’ve made. However, if you want to

preserve the settings then hold Alt as

you press the Upright buttons.

Usethe Loupe

The more accurate your guided upright lines, the

better. The Loupe can be very helpful when plotting guide

lines. The O key toggles the loupe on or off. If you hold Alt

while dragging you’ll also turn on a precision cursor that lets

you drag more slowly for greater accuracy.

19

Drawing

guide lines

Whendragging guide lines with the

Guided Upright command, follow

natural lines that you know should

be horizontal or vertical. We can

make between two and four guide

lines. Ideally make at least one

horizontal and one vertical line.

18

Drag to reposition

The Guided Upright controls can lop off

important parts of the photo, leaving you with an

unwanted crop. The X/Y Offset sliders in the Transform

panel change the position of the image in the window,

but don’t bother with them – simply hold Cmd/Ctrl+Alt

then drag the image to change the position.
