Lesson 11 |
Learning how to rotate image canvas
and cut away unneeded areas |
|
|
|
Introduction |
Basic photo corrections usually
include the general workflow in the
following sequence:
·
Make a copy of the original and work
on the copy.
·
Trim unneeded areas.
·
Ensure that image resolution or
print dimensions are right for use.
·
Clean out stains.
·
Adjust tonal range and remove
unwanted color casts.
·
Adjust lightness and saturation on
specific areas.
·
Sharpen the overall focus of the
photo.
The following lesson will teach you
how to rotate image canvas and then
cut away unneeded areas from the
photo. |
|
|
|
Step #1: |
|
|
·
Open a file with objects slant to
one side and dimensions larger than
desired. |
 |
|
|
|
Step #2: |
|
|
·
Go to the
“Menu bar”.
·
Choose File > Saves as.
Save the opened file in another name
so that we can go back to the
original later when required. |
 |
|
|
|
Step #3: |
|
|
·
Go to the “Menu bar”.
·
Choose Image > Rotate Canvas >
Arbitrary. |
 |
|
|
|
Step #4: |
|
|
"Rotate Canvas”
dialog box appears.
·
Enter 1.2 in
“Angle”.
·
Choose ºCW .
·
Click
[ OK ]
to apply the setting. |
 |
|
Subsequent to rotation, white areas
appear on all sides of the photo,
revealing the default background
color. |
 |
|
|
|
Step #5: |
|
|
From the
“Toolbox”:
·
Look for
“Crop and slice tools”.
·
Select
the
[ Crop ]
tool. |
 |
|
|
|
Step #6: |
|
|
In the
“Options bar”:
·
Enter 2 in
“Width”.
·
Enter 3 in
“Height”. |
 |
|
|
|
Step #7: |
|
|
·
Drag the crop marquee from the upper
left corner, just inside the white
areas, to the lower right corner.
As we drag, the marquee retains the
same proportion, that is 2 × 3, as
specified in the Options bar. |
 |
|
|
|
Step #8: |
|
|
When the marquee touches the lower
right corner and just outside the
white areas:
·
Release the mouse button.
A cropping shield covers the area
outside the cropping selection.
Notice:
There is no need to be precise.
We’ll edit the marquee size later. |
 |
|
|
|
Step #9: |
|
|
In the
“Options bar”:
·
Uncheck
[ Perspective ]
check box. |
 |
|
|
|
Step #10: |
|
|
·
Drag the corner handles to adjust
the size of the marquee, so that the
marquee contains all parts of the
photo we want, and no white areas
are included. |
 |
|
|
|
Step #11: |
|
|
·
Place the pointer inside the crop
marquee.
·
Drag the marquee slightly downward
until the top border of the marquee
touches the top of the highest
building in the photo.
·
Press
[ Enter ]. |
 |
|
The image is now straightened and
cropped to a 2 × 3 ratio. |
 |
|
|
|
Step #12: |
|
|
·
Go to the
“Menu bar”.
·
Choose File > Save.
Save our work and then go to the
next lesson. |

Conclusion |
In this lesson, we learned that
before starting to correct a photo,
we should make a copy of the photo
and work on the copy. Thus, we can
go back to the original later when
required.
We also learned how to rotate the
canvas and cut away unneeded areas
from a photo. |
