Editing images using Microsoft
Photo Editor and Paint
Quick and Easy!
• Microsoft Photo Editor and Paint are
image-editing software applications
that come bundled into Microsoft
Office
• Both have very little of the capability
of Adobe Photoshop
• But they are “free” with Office and
easy to learn.

How to save an image from a
webpage
Let’s go to the NOAA photo library
http://www.photolib.noaa.gov/
• right click your mouse on the homepage
photo
• select “save picture as”
• save file in the same format as it appears on
the webpage
How to save an image from a
webpage
Internet Explorer has
a right-click
“properties”
feature to help you
find out the name
of a file, its size
and its specific
location on the
remote server
Image file formats
• .gif
non-photographic graphics
• .jpg
generally best for photographs
• .bmp
Microsoft proprietary format: not useful
for anything except creating wallpaper for your
Windows desktop. Paint will default to saving files in
.bmp
• This webpage has more information about the
difference between .gif and .jpg
Improving a photo
Use MS Photo Editor to adjust darkness and
lightness of an image and even improve the
color balance of an image. Select:
• Image
• Balance
• Decrease or increase brightness
• Decrease or increase balance
• Use gamma by selecting a color and then
adjust the scale to make the photo go red,
blue or green
Decreasing brightness
Here is the original

Here is picture with
red selected and
the gamma
increased to 2.0
Auto-balance
If you’re not certain
how to adjust your
photo, use the autobalance feature
Resizing images
• Always “constrain” the dimensions of your
image
• “Constrain” means keeping the dimensions in
the same ratio
• If your software doesn’t automatically
provide resizing, note the exact dimensions
of your image
• Photo Editor defaults to a constrained sizing
but width and height need to be changed the
same percentage
Resizing images
The duck picture as an
original:
It is 500 pixels wide
and
546 pixels high
Resizing images
The duck picture as an
original:
Resized image lost its
ratio:
I clicked “allow
distortion,”
Changed the ration and
Dimensions are now:
475 pixel wide and
409 pixels high
Resizing images
What happens when an image is
resized from small to large and large
to small
The original is a
medium-sized image
at 500 x 546 pixels
(width is given first
and then height:
this is standard)
What happens when an image is
resized from small to large and large
to small
Reduced to 200 pixels,
the image still looks
fine but it wasn’t
that big to begin
with.
Let’s reduce it to 50
pixels to make a
small graphic
What happens when an image is
resized from small to large and large
to small
Reduced to 50 pixels,
the image is hard to
read but not too
fuzzy or distorted.
What happens if we
try to resize the
image back up?
What happens when an image is
resized from small to large and large
to small
The 50 pixel image is
resized to 200
pixels.
Now it is fuzzy and
unusable
The adage(s) of this story
• Always copy your image
files before
manipulating them in
case they get “ruined”
• Start with an image file
the appropriate scale
to your purpose. E.g.
use a small file for
icons
• It’s ok to reduce an
image but blowing it up
often doesn’t work.
Cropping images
• First define what
part of the photo
you are saving by
using “define”
• Use your mouse to
change width and
height
Cropping images
• I have selected only
the duck’s head for
cropping
• Select “image”
• Select “crop”
• Use the defaults on
the menu
Cropping images
The duck’s head only
Add an effect
Under “effects,”
select an effect
I choose “chalk and
charcoal” to make
my photo into a
non-photographic
graphic image
Add type
Photo Editor doesn’t let the user add type BUT
Paint does have this function
Close your image in Photo Editor and then
open your image in Paint
Add type
Here is
the
original
image
in Paint
Add type
• Click on the icon of the
letter ‘A’: this lets you
add type
• A cross with a dot in
the middle will appear
on your image. Use it
to create a text box by
dragging it across and
up and down to size the
box.
Add type
• Control the font
size and type
using the fonts
menu (1)
• Add the text in
the text box (2)
• Control the
color of the
font using the
color palette
(3)
Add type
• Notice how the
type box is over
the image?
• That is because
the toggle to
have the text
box over the
image is on
(look for the
arrow)
• Select the
option below it
for an
“invisible” text
box.
Add type
The process is
repeated but
this time,
select the
second
option for
the text box
(look for the
arrow on the
image)
Add type
• The process is repeated
but this time, select
the second option for
the text box (look for
the arrow on the
image)
• Paint doesn’t let us
center the type or
position it flush right
Screenshots
Screenshots are easy and very useful for tutorials.
Just hold down
• CONTROL
• ALT and
• PRINT SCREEN
simultaneously
Screenshots
Paste your screenshot into Photo Editor
Save your original.
Copy it and and then crop it so it isn’t too large.
Typically a screenshot is about 800 pixels across. I
suggest reducing the size 50%.
I often name my files to show their size.
The original might be called duckyorig.jpg and the
version that is 400 pixels across is called
ducky400.jpg. This helps me quickly identify the
different scales of the image.
How to optimize images
• Try not to load images
over 60K for webpages
• Always optimize your
images for faster
loading
• Use shareware or
• Websites that provide
this service
• Photoshop provides
optimization
