Variable Data Sets,

import

Menu: Image > Variables > Data Sets

Shortcut: – See also: Variable Data Sets data sets,

Version: CS2, Variable Data Sets defi ne

CS3

As well as creating data sets inside

Photoshop you can also import sets that

have been created outside the program.

After displaying the Variables dialog

(Image > Variables > Data Sets) press the

Import button and then set the import

options in the dialog that is displayed.

External data sets can be created using a

text editor or with a spreadsheet program

such as Microsoft Excel.

Variable Data Sets,

Menu: File > Export > Data Sets As Files

Version: CS2, Variable Data Sets defi ne

CS3

Once you have created a template fi le,

defi ned the variables and attached them

to template layers, and then made some

data sets, you can generate the data driven

graphics by selecting the Export Data Sets

as Files option from the File > Export menu.

With the dialog open Select a destination

folder and which data set(s) to use in the

process. Add some naming details and

then press the OK button to generate the

pictures.

Variations

Menu: Image > Adjustments > Variations

Shortcut: – See also: Color Balance

Version: 6.0, 7.0, CS, CS2, CS3

The Variations feature is often used for

removing color casts in photographs. It is

based on a color wheel, which is made up of

the primary colors red, green and blue, and

their complementary colors cyan, magenta

and yellow.

Increasing the amount of one color in

an image automatically decreases its

complementary. Put simply, increasing

red will decrease cyan, increasing green

will reduce magenta and increasing blue

will lessen yellow. You can target the color

changes so that they only affect a selected

group of tones by choosing highlights,

midtones or shadows (1).

The strength of the changes is altered with

the Fine/Coarse slider (2). In addition the

dialog also contains options for adjusting

saturation (4) and brightness (3) and

previewing clipping (5).

Variable Data Sets,

defi ne Menu: Image > Variables > Defi ne

Shortcut: – See

also:

Variable Data Sets data driven

graphics, Variable Data Sets data

sets

Version: CS2, CS3

Defi ning a data set is a process by which

layers (1) in the base or template document

are linked with a variable type (2) and

name (3).

To defi ne this relationship you must fi rst

create the base image making separate

layers for each image/text part that will be

replaced with a piece of data from the data

sets. Next, select Defi ne from the Image >

Variables menu to display the Variables

dialog. Now select the name of the layer

from the Layer drop-down menu and then

pick the variable type (2). All the layers in

the template document will be listed.

Depending on the layer you will have a

different set of choices here. Text layers can

be defi ned with either Text Replacement

or Visibility variables whereas image

layers can be associated with either Pixel

Replacement or Visibility variables.

Finally, input a name for the variable or use

the one suggested by Photoshop.

Once the variables are associated with the

template picture then you can move on to

creating data sets.

Vector

Bitmap

Vector graphics

Menu: –

Shortcut: – See also: Bitmap images

Version: 6.0, 7.0, CS, CS2, CS3

Unlike photographs which are constructed

of pixels, vector graphics are created

with a series of lines and curves that are

mathematically designed. Such pictures

can be resized and moved with no loss in

quality and print with no jagged edges.

Typically, pictures created in drawing

packages such as Adobe Illustrator are

vector based. However, some tools in

Photoshop, which is primarily an editor

of pixel-based photos, do create vector

graphics. The Shape and Type tools use a

vector approach in the graphics and layers

they create.

Some editing techniques require the

conversion of the vector drawings to a

bitmap picture. This process is achieved

by selecting the layer with vector content

and then choosing Layer > Rasterize.

As computer screens

display all picture

content, both vector

and bitmap, as pixelated

images, enlarged versions

of vector graphics will

still show stepped or

jagged edges that won’t

be evident when the

picture is printed.

Vector Mask

Menu: Layer > Add Vector Masks

Shortcut: – See also: Masks

Version: 6.0, 7.0, CS, CS2, CS3

A vector mask is a hard-edged layer mask

(1) that can be used like any other mask in

Photoshop. Vector masks are often used

to create a sharp-edged transition when

montaging several images together (3).

Unlike standard masks vector masks are

not pixel based and so maintain their hard

edge even when resized and adjusted. For

this reason vector masks are edited using

the Shape and Pen tools not pixel-based

drawing or painting tools.

Layer styles and effects can be easily applied

to layers containing vector masks (2).

Entire layer masks can be created using

the Layer > Add Vector Mask > Reveal

All and Layer > Add Vector Mask > Hide

All commands. The mask can be edited

by clicking onto the mask thumbnail in

the Layers palette and then drawing on

the canvas surface with the Shape or Pen

tool.

Version Cue

Menu: –

Shortcut: – See also: Versions

Version: CS2, CS3

Version Cue is an Adobe Creative Suite

component program which is designed

to manage projects within a workgroup

environment.

If you currently share images and design

documents around a group of people

with each person contributing his or her

changes then Version Cue provides the

management tools necessary to ensure

that changes made in the design process

are recorded and tracked.

This said, two Version Cue fi le management

features that are very useful even for the

non-workgrouped user are:

Versions – A feature designed to save and

track different versions of the same fi le.

All versions can be viewed in Bridge and

any individual version can be promoted in

the version stack at any time. This utility

is great for managing sequential changes

in a project.

Alternates (CS2 only) – This option

allows you to save a complete copy of the

current project at any time. Each copy can

then be changed and altered independent

of each other providing alternative results

from the same fi le. This feature is great

for tracking branching, non-sequential,

changes.

Version Cue is only included when

you purchase ‘Suite’ versions of Adobe

products.
