Lab 02: Digital Photography Editing
Overview
This lab will introduce Irfanview to
manipulate digital pictures. You will manipulate a provided .jpeg image with Irfanview,
and then import portions of the images into a MS-PowerPoint document. Please feel free to use any other
photo editing software that is available to you and/or that you are familiar
with.
Irfanview is shareware and can be downloaded
from http://www.irfanview.com/ for
windows users. A freeware program for mac users can be downloaded from http://www.gimp.org/ .
Procedure:
Create three digital images
from the one digital image provided.
(NOTE: You don’t have to use the image
specified in Step 1 below.
I’d prefer you use a personal digital photograph of yourself. Any clipart image will suffice.)
- Retrieve file
H:\COSC109\Datafiles\Lab02_Digitalphoto_Datafile.JPG . You may substitute this image with
a .jpg file of yourself.
- Save that file to your COSC109\CompletedLabAssignments
folder.
3.
Edit
and modify your image using photo editing software. Select Start/Programs/Irfanview/.
Now click File/Open, and select the
folder where you stored your downloaded digital image; and open the image.
- Select only part of your digital image for further
work. There are
three options in Irfanview: Cut-selection,
Cut-leave selection, Crop selection.
- Cut-selection will cut out the selected
rectangle. The cut rectangle is replaced with black color and the
original image size is still the same.
- Cut-leave selection will cut out the part around
the selected rectangle and keep the selected rectangle. The part around
the selected rectangle is replaced with black color and the original
image size is still the same.
- Crop selection will cut out the part around
the selected rectangle and keep the selected rectangle. The area around
the selected part is "thrown away" and the image size is now
only the size of the selected part.
- Crop your
picture. Use the mouse to draw a
rectangle around your portrait in the picture (cut out most of the plain
background), then select click Edit/Crop selection. If you want
to re-draw the rectangle, just click your mouse outside of the selection,
this will make the selection disappear.
- Check the size of your picture. Your picture should not be
larger than appr. 3" x 2" (or 2"
x 3"). To check the size of your picture or change the size, use Image
/ Resize-Resample. Make sure to choose the option "inches"
in the unit field. You can change the number of inches by increasing or
decreasing the height and/or the width fields. Notice that both values for
height and width change, even if you adjust only one of those fields. This
is Irfanview's way of ensuring that your image
will not be distorted.
- Save your picture. Use File / Save As to save this picture to your COSC109\CompletedLabAssignments folder as mypict1.jpg.
- Rotate your picture. Use this new file mypict1.jpg,
but this time rotate your picture left or right after cropping. Use Image / Rotate L (or Rotate R) to rotate the picture. Use File
/ Save As to save the picture
to your COSC 109 folder as mypict2.jpg.
- Use Special Effects on your picture. Open the file mypict1.jpg again
(use File/Open), but this time use the various tools under Image / Effects to enhance your
picture after cropping. Use File /
Save As to save the enhanced picture as mypict3.jpg.
Create a PowerPoint Presentation with
our new three digital images
You
now have three picture files: mypict1.jpg,
mypict2.jpg, and mypict3.jpg. In
the next step, you will create a digital photo album using Microsoft
PowerPoint. When finished – your presentation should look similar
to the image to the left.
- Start Programs
/ Microsoft PowerPoint. Type the following title on the title slide: Joe
Student (Use your name instead of Joe Student) and Digital Photo
Album.
- Insert a
new slide and use the two-column layout. Write Introduction
in the title bar. In the left column, introduce yourself by writing your
full Name, Major, Academic Year. Use the right
column to insert the first picture you produced (the cropped picture). Use
Insert/Picture/From File, navigate to the location of your picture
and select your cropped picture.
- Insert a new slide using the two-column layout again. Write My Major in the title
bar. This time, in the left column share something about your major and
what you plan on doing after you graduate. In the right column, insert
your rotated picture.
- Insert a new slide, this time using the regular
title and text layout.
Write My Hobbies in the title bar. Insert your special effects
image as the background for this slide.
For Office
2010: Select the Design
tab, then Background, and format the background. Select Fill,
then picture or texture fill. Select Insert from File, navigate
to the location of your special effects picture and insert the picture.
For Office
2003: Select Format
/ Background, from the pull-down menu select Fill Effects, click on
the picture tab, click on the Select Picture button and select your
picture
Make sure to
click only on "Apply" and not on "Apply to All",
since we want this background only to appear on this slide and not on the first
two we already created. Share something about your hobbies on this slide and
please also share which special effect you used.
- Save your PowerPoint presentation to
your COSC109 folder under the filename: Lab02_Submit.pptx
- Submit your PowerPoint presentation to your
instructor as an e-mail attachment.
Note: Keep all your .jpg files (xxxxx.jpg).
Jpg is one of the picture formats used on the World Wide Web. Your .jpg
pictures will be used in future labs.
Submitting
your file:
Send an e-mail
to webster@towson.edu and
attach one file: Lab02_Submit.pptx
with the Subject Heading “COSC
109.102: Submitting Lab Assignment #2”
