PHOTOSHOP

Star bursts
If you want star bursts to highlight an event
(for a brochure) or a Web site, open Pho-
toshop. Load your image or create a new
one. Select Filter > Render > Lens Flare
from the menu. Select Brightness and
Flare type. Place the cross-hair on the
image and click O K. This effect looks great
when combined with neon glows.

The drop shadow
If the Layers option in Photoshop intimi-
dates you, this exercise will help you get
familiar with the tool. Apply cool shadow
effects to your words and images using
this option.
First create a new image and a new
layer (shape). Select the text marquee tool
and type the text you want. Fill it with any
colour or texture. Without deselecting
your marquee selection, create a new layer
(shadow). Fill it with the colour you want.
Now drag the layer-shadow below the
layer-shape so the shadow appears behind
your text. Go to Filter > Blur > Gaussian
blur (radius 4.7). Select the Move tool and
move the shadow to wherever you want it
to be (using the keyboard arrows keys).
Finally, move it 4 pixels to the right and 2
pixels down.

X-Files unveiled
If you want to impress your friends by
creating the X-Files logo yourself, follow
these steps. Create a new
image (7 cm x 7 cm). Click
on Layer > New Layer and
set background colour to
black. Click on the Type
marquee tool and type ‘X’.
Use a normal font (Times
Roman and Filter > Distort
> Ripple ). Set the fore-
ground colour to Green.
Press [Alt] + [Del ] keys
simultaneously to fill ‘X’ with green. You
can try this on different text to get the
final effect. Alternatively, you can try
using the Magic Wand tool to fill the text
with an appropriate colour.

Magnifying Glass
With the magnifier tool selected, click-and-
drag marquees a rectangle. The current
window is maximised and the marked
section is magnified to fit. Double-click
on the magnifier to reset to the default
value of 1:1. The maximum magnifica-
tion is 16:1. Note that the Magnifier tool
will retain the window dimensions and
zoom within those boundaries, whereas
the Zoom In/Out function under Win-
dow will actually change the window
dimensions as well as the zoom status.


Layer effects
This feature of Photoshop facili-
tates adding shadows, glows,
bevels, and embossing to text or
to any other item that resides on
a layer. Every time a change is
made to a layer, the effects are
automatically updated. For example, if
you move the text, the shadow associated
with it also moves.This feature is available
in Photoshop 5.Control
When moving selections (marqueed,
ellipse, lassoed...) use the [Shift ] key to
constrain the movement. For example,
selecting an area and moving it away with
key is depressed, the dragging is
constrained to be exactly hori-
zontal or vertical or at an angle
of 45 degrees. This action works
even if the [Shift ] key is pressed
after the dragging is already
underway. Example: Move text
horizontally only. This trick is
particularly good with the blend
tool and can be used to
create gradients that are truly
vertical/horizontal.

 

 

 

 

 

 

 

 

 

 

Add shadows and colour

Old image files can be made to look new
again. In this example, not only has the
shadow been reduced, the colours have
been changed and enhanced. Create a
duplicate of your image by clicking Image
Duplicate and set the mode to greyscale.
Next, select Filter > Blur > Gaussian Blur ,
and blur the image such that all details are
lost (Radius value between 3 and 6 pix-
els). Click the original image to bring up
the window, then choose Select > Load
Selection , and use the greyscale copy as
your selection.
Set the background channel to Black,
check the Invert box, and click O K. After
loading the selection, you should see a
dotted line around the shadow areas. You
can deselect the small areas outside the
figure with the Lasso tool while holding
down the [Alt] key.
Now choose Edit > Fill . Under Con-tents
, select 50% grey. Under Opacity ,
enter 100%. Under Mode, select Color
Dodge, then click O K. The resulting
image should have the shadows reduced.

Buttons with a layered look
To create bevelled buttons, open a new
image in Photoshop and create a new
Layer (Outside). Select the Marquee tool
for a rectangular or circular button. Next,
choose lighter and darker tones of the
same colour. Select the gradient tool,
click the top-left corner of your marquee
selection and drag to the bottom-right.
Create a new layer (Inside ). Click Select
> Modify > Contract and then on
Smooth. (If you are working with a rec-
tangular shape don’t smooth the selec-
tion.) Select the Gradient tool and repeat
the above step but start at the bottom-
right and drag to the top-left of your
selection. Press [Ctrl] + [D] to deselect.
For a smoother effect, click Filter > Blur
> Gaussian blur on the Inside layer.

History in action
If you haven’t been making active use of
the History palette, you don’t know what
you are missing. This palette maintains a
list of all the recent actions, allowing you
to backtrack to any previous stage in
your image-editing process. You can also
take snapshots of your project on the
way. When using this palette, you can
either delete a step or undo these steps.
However, you cannot return to a step and
change its parameters.
The History brush can also be used to
paint the contents of a prior version of
the image on to the latest version. For
example you can apply a Gaussian Blur
to your entire image, remove it and then
use the History Brush to paint the Blur
on some areas of the image.

Nudging
For small-sized-image-adjustments, use
the arrow keys—these can help you
correct minute errors since one pixel is
moved at a time. For fixing small patch-
ups on your image: use the rubber stamp
cloner, hold down the [Alt] key and find a
good area to steal from and position it,
then use the arrow keys again.

Control
When moving selections (marqueed,
ellipse, lassoed...) use the [Shift ] key to
constrain the movement. For example,
selecting an area and moving it away with
key is depressed, the dragging is
constrained to be exactly hori-
zontal or vertical or at an angle
of 45 degrees. This action works
even if the [Shift ] key is pressed
after the dragging is already
underway. Example: Move text
horizontally only. This trick is
particularly good with the blend
tool and can be used to
create gradients that are truly
vertical/horizontal.
