| Auction Orbit - Using IrfanView To Enhance
Your Images |
|
"A
picture is worth a thousand words... A clear picture is worth
even more!"
Although today's digital cameras
are capable of taking some pretty impressive shots, there's
still room for improvement. When you insert a picture into
online auction listings, you normally want to have the best
picture possible to avoid confusion and to ensure that the
viewer has a clear representation of what the item looks
like. Luckily there is a freeware program available that
enables you to make common adjustments to your digital photographs
to enhance the quality. From changing the brightness, to
resizing and sharpening, IrfanView allows you to easily
tweak your pictures.
This tutorial will walk through the
steps required to perform a variety of image-enhancement
functions using the freeware program, IrfanView. I will
be using the image below to demonstrate a variety of functions
available through IrfanView, if you wish to follow along
simply save the picture below to your hard drive (right-click
on it and select 'Save Picture As'). You can also use your
own image(s) and still following the steps herein.

Click
on any topic below to jump to that particular section of
this tutorial.
Install IrfanView
IrfanView is a freeware application
developed by Irfan Skiljan which allows users to
enhance digital pictures. The application is very
fast and is compatible with Windows 95 and up. Before
you can use the software, you first have to download
and install it.
1.) Download the
free IrfanView program available here.
Make sure to save the file to a location on your
hard drive that you will remember.

2.) Once the download
is complete, launch the setup file that you just
downloaded. Read through the simple instructions
presented to complete the install. You can specify
a custom installation directory and other options
on the initial setup page (or you can keep the default
values). NOTE: IrfanView attempts
to install the eBay Toolbar and place eBay shortcuts
into Internet Explorer by default. I would advise
that you uncheck these options on the first installation
page to avoid installing these additional programs
(and possible Spyware).

3.)
After completing the IrfanView installation,
open the program up by double-clicking on the desktop
icon or accessing it through the Start Menu. IrfanView
is now open and ready for use.

Open A Picture
After IrfanView has been installed and launched,
you are set to open up the picture that you wish
to enhance.
1.) There are three
(3) main ways to open up an image file using IrfanView.
To open up the image that you wish to manipulate,
perform any of the following operations:
2.) After performing one of the
commands listed above, you will be presented with
the 'Open Dialog Window'.
From here, navigate to the directory that contains
the image you wish to enhance. When you see the
picture you want to use, click on it to select it.
You will then see a preview of the image, and various
details about it such as the resolution and size.
Click on the 'Open' button to open
the specified picture into IrfanView.
NOTE: Alternatively
you can double-click the file-name to open it into
IrfanView.

Resize
The Picture
It is often a good idea to scale down a higher-resolution
image if you plan on posting it on a Web site or
auction listing. If posting to a Web site, it is
advised that the image not exceed 760 pixels wide
or else the user will have to scroll horizontally
(annoying).
1.) After opening
the picture, select IMAGE > RESIZE/RESAMPLE
from the File Menu. Alternatively, you can press
CTRL+R. The Resize/Resample Image
Properties will appear.
Within the Resize/Resample Image Properties,
you will be able to specify a new resolution for
the image and which type of resampling method you
wish to use (if any).
2.) For this example
I will resize the picture to a resolution of 400
x 300 pixels (which is the exact size that
eBay resizes the images to if you use their default
image hosting service). If the 'Preserve
Aspect Ratio' option is checked, then whenever
you change the dimension of either the width or
height, the other value will automatically change
so that the picture will never appear distorted
(recommended). IrfanView also offers a lot of shortcuts
for resizing your pictures with a single-click.
3.) The next step
is to select the resampling method that you wish
to use. There are a variety of resampling algorithms
available in IrfanView, each one varies slightly
in the quality of the output and the time it takes
to complete the process. For examples and information
on many of the common resampling algorithms, please
look here.
Typically, to achieve the highest quality results
you will want to use the Lanczos Filter
(slowest) sampling method.

4.) After specifying
all of the details that you wish to use, click on
the OK button to immediately resize
the picture.

Brightness & Contrast
Adjusting the brightness and contrast of a
picture is one of the most common enhancements for
bringing clarity into your pictures. Even a relatively
dark and non-contrasting image can turn out great
if the brightness and contrast are tweaked accordingly.
1.) Select IMAGE
> ENHANCE COLORS from the File Menu.
Alternatively, you can press SHIFT+G.
The Enhance Colors Properties will appear.
Within the Enhance Color Properties,
you will be able to change a variety of parameters
for the selected image. This includes adjusting
the brightness, contrast,
color balance, gamma correction,
and saturation.
NOTE: For your convenience,
a real-time preview of the modified image is displayed
under the 'New Image' frame within the Enhance Colors
Properties. Each time you change the values of any
color property, the New Image preview will
update automatically.
2.) First, lets brighten
the picture a bit. Click on the slider handle below
the 'Brightness' caption and drag
it to the right until it is at approximately 50.
You can also manually enter a brightness value into
the text field directly to the right of the slider
bar.
3.) Now that we have
brightened the picture, the contrast should also
be increased slightly. Drag the slider handle beneath
the 'Contrast' to approximately
35. As with the Brightness option,
you can manually enter a contrast value into the
text field directly to the right of the slider bar
if you wish to do so.

4.) After specifying
the new brightness and contrast values, you can
either click the Apply button to
update the original image with the new properties
while remaining in the Enhance Colors window (you
can then cancel the changes to revert back to the
original values), or you can click OK
to apply the changes and exit back out to the main
IrfanView window.

Sharpen The Picture
Sometimes the edges within a picture are glazed
over or out-of-focus. This can be caused by a slow
shutter speed, or accidentally moving the camera
slightly while taking the picture. Using IrfanView,
you can bring clarity into the picture by making
the details sharper..
1.) Select IMAGE
> SHARPEN from the File Menu. Alternatively,
you can press SHIFT + C. The image
will automatically be sharpened by one level.
2.) To further increase
the image sharpness, repeat step #1 as many times
as needed. In this example, I pressed SHIFT
+ C three (3) times to
bring clarity into the picture.

Blur The Picture
After sharpening the picture,
more details are apparent but at the same time,
some of the edges seem a little too sharp. This
problem can be overcome by applying a Blur effect
to the image.
1.) Select IMAGE
> EFFECTS > BLUR from the File Menu.
The image will automatically be blurred by one level.
2.) To further blur
the image, repeat step #1 as many times as needed.
In this example, I only blurred the picture once
to slightly soften the edges.

Adjust The Colors
The overall color (tint) of
the example picture is a bit depressing. Lets adjust
it to make the clock appear as though it were taken
in a more well-lit environment.
1.) Select IMAGE
> ENHANCE COLORS from the File Menu.
Alternatively, you can press SHIFT+G.
The Enhance Colors Properties will appear.
Within the Enhance Color Properties,
you will be able to change a variety of parameters
for the selected image. This includes adjusting
the brightness, contrast,
color balance, gamma
correction, and saturation.
NOTE: For your
convenience, a real-time preview of the modified
image is displayed under the 'New Image' frame
within the Enhance Colors Properties. Each time
you change the values of any color property, the
New Image preview will update automatically.
2.) Lets increase
the Color Balance sliders to the
following values:
3.) Now, set the
Gamma Correction value to 1.05.

4.) After specifying
the new Color Balance and Gamma Correction values,
you can either click the Apply
button to update the original image with the new
properties while remaining in the Enhance Colors
window (you can then cancel the changes to revert
back to the original values), or you can click OK
to apply the changes and exit back out to the main
IrfanView window.

Add A Watermark
Now that we've taken the time
to enhance this image in so many ways, it would
be a shame to have another person steal the picture
and claim it as their own. IrfanView allows you
to create simple watermarks by placing a string
of personalized text over the picture at any given
location. For advanced watermarking techniques using
various other graphic editing utilities, please
refer to my Watermarking
tutorial.
1.) Left-click and drag
a box-selection around the area in the picture where
wish to insert text.
2.) Select EDIT
> INSERT TEXT INTO SELECTION.
Alternatively, you can press CTRL
+ T. The Add Overlay Text To Image
Properties will appear.
3.) you may now enter
the text that you wish to appear on the top of your
image. Make sure that the 'Text is Transparent'
option is checked. You can also customize the font
appearance by clicking on the 'Choose Font'
button.

4.) After specifying the text
phrase you wish to use, and customizing the font
to meet your needs, click OK to
apply the text phrase to the top of the image.
NOTE: If the text is not in the
location you wanted it to be or the font style does
not look good, press CTRL + Z to
undo the operation, and then repeat steps 1-3 above.

Save The Picture
The last step in completing
the photo-editing process is to save the final product.
The steps below outline the process of saving the
picture so that it is compressed and suitable for
online auctions and activities.
1.) Select FILE
> SAVE AS from the File Menu. Alternatively,
you can press S. The Save Picture
As Dialog Window will appear.
2.) In the drop-down
box to the right of the caption, 'Save as
type', select JPG - JPEG Files.
Another small property window will appear that will
allow you to further customize the file format and
saving options. For the most part, the options can
remain as they are by default.
3.) Since this picture
will be used online, adjust the compression from
80 to 65. This will ensure that
the file still loads quickly while at the same time,
the quality will remain quite good.
4.) Navigate to the
folder where you wish to save the file, and then
enter a descriptive File name.

5.) After specifying
the compression settings that you wish to use, click
OK to save the image to the folder
and file name that you specified.
