Ever found yourself trying to make an elliptical selection with a round tool?

Well here are a couple of great new ways to get a handle on time and learn some

Adobe® Photoshop® 5.0 timely techniques.

Adobe Senior Creative

makes selections the

easy way with

Photoshop 5.0.

INTERMEDIATE

TIMESAVING SELECTIONS

1. The goal of this project is

to make elliptical selections

easily and quickly. We’ll start

by making a standard selection

with the ellipse tool as shown

in this image. We can access

the ellipse tool by clicking and

holding the marquee tool on

the tool palette. No need to

make the ellipse selection

exact. That’s the beauty of

this technique.

Shortcuts

Throughout this

document, “Command/

Ctrl” means Command

on the Macintosh and

Ctrl on Windows.

2. Now, to introduce a new

feature found only in Adobe

Photoshop 5.0 or later… From

the Select menu, choose Trans-

form Selection, as shown to the

right. This new feature will

transform the shape of the

selection without altering its

contents. It’s new! It’s wild!

You’ll use it all the time!

3. WOW! You can now rotate,

scale, and distort the selection

until the ellipse fits the shape of

the face of the watch. Press the

Enter key and the newly trans-

formed selection will be pre-

cisely in position. Amazing!

But wait – there’s more!

Selections

To reshape the selec-

tions, simply select

and move any of the

control points available.

To rotate the selection,

move the mouse just

outside the selection

until you see the

rotation icon, and then

rotate the selection.

Special note: You can

now change the point

of rotation by moving

the central control

point to any other

location on the image.

Technique number two!

1. Here’s another, less obvious

approach to transforming a

selection. We’ll use it to trans-

form the watch as we did with

technique number one. How-

ever, this time we’ll get a special

kind of preview!

Once again, make a selection

with the ellipse tool as shown to

the right. Remember, there’s no

need to be exact.

2. In the tool box, click on the

edit in quick mask mode icon.

The flashing selection will now

be displayed as a Quick Mask.

The default color for the Quick

Mask is red with a 50% opacity.

As you can see here the Quick

Mask appears like a transparent

layer of plastic over the image.

Painting on this layer with

white will add to the selection

and painting with black will

subtract from the selection.

Quick masks

Make a selection. A

shortcut for the edit in

Quick Mask mode is to

press the Q key on the

keyboard.

3. This time, choose Free

Transform from the Edit menu.

4. The transformation control

vectors appear as before, but

this time we are transforming

a visible mask. The selection

area becomes much more clear

and distinct.

5. As before, we can rotate,

scale, and distort the Quick

Mask with the transformation

tool until it fits the watch face

exactly. Then we can press the

Enter key to apply the

transformation.

Super user tip

Double-clicking inside

the transformation

region is a quick and

easy way to apply the

transformation.

6. Fifty percent red is the

default color for the Quick

Mask. However, it’s possible to

change the color of the Quick

Mask to help make the preview

of the selection more distinct.

On the the Channels palette,

double-click the words Quick

Mask. The Quick Mask Options

dialog box will appear.

7. Experiment with changing

the color and opacity of the

Quick Mask until it is more

apparent with your image.

8. As you can see in this ex-

ample, the new Quick Mask

color makes the selected area

more distinct. The selection can

be transformed with more

accuracy when the color has

greater contrast.

Cropping an image

This same technique

can be used to

preview the cropping

of an image. Try

setting the Color to

white and the Opacity

to 100% to block out

the image outside the

cropping area.

9. After completing the trans-

formation of the Quick Mask,

select the edit in standard mode

icon, or press the Q key on your

keyboard, to revert the Quick

Mask back to a selection.

Channels

To make a Quick Mask

into a channel, target

the Channel palette,

select Duplicate from

the pop-up menu, and

click OK. This makes a

copy of the Quick Mask

and a permenant alpha

channel you can load

as a selection anytime.

10. Here’s a simple way to use

this selection. Open up a new

image. In this case, I’m using

an image of a desert road

stretching to the horizon. Select

the entire image by choosing

Select > All or Command/

Ctrl+A. Then copy the selection

by choosing Edit > Copy or

Command/Ctrl+C. Close the

image you copied.

11. With your selection made,

choose Edit > Paste Into. Then

as the final step in this project,

set the Mode for this newly

created layer to Multiply, with

an Opacity of 85%.

And there it is: You’ve learned

how to control time and space.
