Lesson 9
Resizing Images |
We often want to resize our images
so that they match a specific size. |
|
|
|
Introduction |
In this lesson we will cover how to
most effectively resize images
either for the web or for printing.
Images are resized differently for
these two applications, as well as
depending on whether they will
increase or decrease in size. |
|
|
|
Step #1: Select an Image |
|
|
We have selected this image from the
“Photo Well” for this lesson. |
 |
|
|
|
Step #2: Standard Edit Screen |
|
|
When we select “Standard Edit”
from the “Edit” choice on the
Main menu, we will come to the
“Standard Edit Screen”.
|
 |
|
|
|
Step #3: Get
To Image Size |
|
|
From The Main menu, select:
[ Image ]
From the 1st
drop down menu, select:
[ Resize ]
From the 2nd
drop down menu, select:
[ Image Size ] |
 |
|
|
|
Rule #1: Size
& Resolution are Linked
The linking between these occurs
automatically. If you change either
the resolution or the size, the
program will adjust the other to
correspond.
These adjustments in size and
resolution occur without any loss in
quality. |
Resolution & size are linked. Under
normal circumstances, you cannot
change one without changing the
other.
If you increase the resolution – the
image size is decreased.
If you decrease the image size – the
resolution is increased.
If you decrease the resolution – the
image size is increased.
If you increase the image size – the
resolution is decreased. |
|
Rule #2:
Minimum Printing Resolution |
The minimum resolution for printing
an image should be 200 dpi.
If you print at a resolution below
this, image quality will suffer.
You can print at 200dpi or above
with excellent quality. |
|
|
|
|
Rule #3:
Resampling – A Trick |
Resampling is a computer software
trick that creates new pixels based
on other pixels in the image.
It is used for situations where you
do not have enough pixels to print
at the size and resolution you want.
You can add up to about 33% more
pixels, through resampling, before
image quality begins to noticeably
degrade. |
|
Rule #4:
Resampling – On or Off |
Always start with “Resampling
Off”. |
|
|
|
Step #4:
Initial Settings |
|
|
The “Image Size” screen will
appear set exactly the way it was
the last time that you used it.
Therefore, you must always check if
it’s set the way you want it.
The two settings to check are:
[ Resolution ]
[ Resample Image ]
|
 |
|
Note: Resizing
for Web |
Resizing for the web is very easy.
We always have enough pixels and we
only need a small resolution – 72.
Therefore we just:
Set the resolution at 72
Turn Resampling ON
Set the image size you
want |
|
|
|
Step #5a:
Resizing For Web |
|
|
When we wish to post an image on the
web, we need to make some settings
changes.
We should always start with:
“Resample” =
OFF
Set the resolution to:
[ 72 ]
Note that the size becomes too
large. |
 |
|
Step #5b: Web
Settings |
|
|
Now set:
“ Resample” =
ON
Set one of the dimensions
that you want. In this example, we
set the height at:
[ 8 ]
The program will set the other
dimension to match.
Since we are making the image
smaller, we should set:
[ Bicubic Sharper ] |
 |
|
|
|
Note: Resizing
For Printing |
|
|
Step #5 below: |
Resizing for printing is more
complicated. We don’t always have
enough pixels to print at the
minimum resolution for printing –
200 dpi.
When we don’t have enough pixels to
print the size that we want – we
need a bigger print.
Set the resolution to
200
Turn Resampling ON
Set the image size that
you want |
|
Step #6 below: |
When we have more pixels than we
need to print the size that we want
– we do not need
bigger print.
Set the resolution to
200
Turn Resampling OFF
Set the image size that
you want
The program will reset the
resolution to match |
|
Step #5a:
Resizing for Printing - Need Bigger
Print |
|
|
When we want to print an image on
the printer, we need to make some
settings changes.
We should always start with:
“Resample” =
OFF
Set the Resolution to:
[ 200 ]
Note that the size becomes too
small. |
 |
|
Step #5b:
Print Settings |
|
|
Now set:
“ Resample” =
ON
Set one of the dimensions
that you want. In this example, we
set the height at:
[ 8 ]
The program will set the other
dimension to match.
Since we are making the image
larger, we should
set:
[ Bicubic Smoother ] |
 |
|
Step #6a:
Resizing for Printing – Don’t Need
Bigger Print |
|
|
When we wish to print an image on
the printer, we need to make some
settings changes.
We should always start with:
“Resample” =
OFF
Set the Resolution to:
[ 200 ]
Note that the size is too large. |
 |
|
Step #6b:
Print Settings |
|
|
Leave:
“ Resample” =
OFF
Set one of the dimensions
that you want. In this example, we
set the width at:
[ 10 ]
The program will set the other
dimension to match.
The program will set the resolution
to match the size. |
 |
|
|
|
Step #7a:
Without Rulers |
|
|
This is how your image appears
without “Rulers”
indicating the present size of your
image.
We feel it’s convenient to have
“Rulers” displayed.
|
 |
|
Step #7b: Set
Rulers On |
|
|
Take the following steps if you want
the “Rulers” displayed.
From the Main menu, select:
[ View ]
From the drop down menu, select:
[ Rulers ] |
 |
|
Step #7b:
Rulers On |
|
|
Here is our image with “Rulers”
present.
They will remain present every time
you use the program, unless you turn
them off. |
 |
|
|
|
Conclusion |
In this lesson we covered how to
effectively resize images for the
web and for printing. Images are
resized differently for each of
these applications, and also
depending on whether they will be
made smaller or bigger. |
