Same
Technique- Different Tools
This tutorial will show how to solve
design problems often faced by designers in the computer graphics
industry. As an added bonus, two design tools have been used,
to demonstrate the differences between the main types of design
packages on the market, this will also help show how the same
effects can be achieved through different methods.
The
Brief
The aim of the exercise is to transform
the image below from a clear, still scene to a more moody image
with heavy clouds and rain.

To achieve this you must replace
the sky, add ripples to the water and add the fake
rain.
Using
Photoshop
As with Satori, there are various
ways to tackle problems in Photoshop and the more that you experiment
with the program it becomes more obvious which methods suit
your own personal working style. The examples below show one
route that you could take to solve the design problem.
The images used in this tutorial
are samples provided from various photo-libraries. It is not
essential to have the exact images featured, as the tutorial
is meant to show techniques which can be used on any image.
|
Load your
first image into Photoshop. This base layer will be
used as your document Background.
|
Duplicate
this layer from the Layer menu. This creates
a second layer with the same image, that an Alpha
channel can be added to.
|
|
Now find
a suitable image that can be used for the replacement
sky. Dont worry about the contrast, brightness
and aspect of this image as you can change this later.
|
Using the
Image Size dialog (from the Image menu),
with the constrain properties box unchecked, you can
alter the aspect to match your first image.
|
|
Back to
your original image, use the Magic Wand tool and Cut
to remove the black sky on the top layer. For this
image a small tolerance value was used as the sky
was mostly black, with more detailed skies a higher
value would be necessary, using a User Mask may give
better results if the Wand cannot select all areas.
|
Now create
a new layer and move it so that it lies directly below
your sky-less image. Right-click over the Sky
image and select all. This image can now be cut and
pasted to the empty second layer of the main canvas,
and the composition (above) should be immediately
visible.
|
|
Still on
this layer, use the Brightness/ Contrast controls
(Image/ Adjust) to darken the sky so that the images
overall appearance blends seamlessly.
|
The original
sky canvas can now be discarded, leaving your composited
image. To create the rain add another layer filled
with black to your canvas and use the Noise filter
to add white specks.
|
|
You can
now use another of Photoshops arsenal of filters,
Motion Blur, to streak the Rain-drops
at an angle of about 30 degrees off the vertical,
to simulate movement.
|
Set this
top layer to Screen on the Composition
Option Menu from the Layer list to reveal the background
to finish the project.
