essential skills: photoshop CS3

Introduction

Photoshop has helped revolutionize how photographers capture, edit and prepare their images for viewing Most of what we now see in print has been edited and prepared using the Adobe software The image-editing process extends from basic retouching and sizing of images, to the highly manipulated and preconceived photographic montages that are commonly used by the advertising industry This book is intended for photographers and designers who wish to use the

‘digital darkroom’ rather than the traditional darkroom for creative photographic illustration The information, activities and assignments contained in this book provide the essential skills necessary for competent and creative image editing The subject guides offer a comprehensive and highly structured learning approach, giving comprehensive support to guide Photoshop users through each editing process An emphasis on useful (essential) practical advice and activities maximizes the opportunities for creative image production

Acquisition of skills

The first section of this book is a foundation module designed to help the user establish an effective working environment and act as a guide for successful navigation through the image-editing process from capture

to print Emphasis is placed on the essential techniques and skills whilst the terminology is kept as simple as possible using only those terms in common usage

Application of skills

The subsequent modules extend and build on the basic skills to provide the user with the essential techniques to enable creative and skilful image editing The guides explore creative applications including advanced retouching, photomontage, vector graphics, special effects and preparing images for the web Creative practical tasks, using a fully illustrated and simple step-by-step approach, are undertaken in each of the guides to allow the user to explore the creative possibilities and potential for each of the skills being offered

Anitra Keogh

introduction

A structured learning approach

The study guides contained in this book offer a structured learning approach and an

independent learning resource that will give the user a framework for the techniques of digital imaging as well as the essential skills for personal creativity and communication

The skills

To acquire the essential skills to communicate effectively and creatively takes time and

motivation Those skills should be practised repeatedly so that they become practical working knowledge rather than just basic understanding Become familiar with the skills introduced in one study guide and apply them to each of the following guides wherever appropriate

Supporting DVD

A supporting DVD and dedicated web log (blog) has been set up to enable users to access current information The address for the blog site is: www.photoshop essentialskills com.

The supporting files can be accessed through the Bridge interface (Computer > CS3_DVD)

Research and resources

You will only realize your full creative potential by looking at a variety of images from different sources Artists and designers find inspiration in many different ways, but most find that they are influenced by other work they have seen and admired

The DVD has images and movies available to support and guide the learning process

essential skills: photoshop CS3

Essential information

Th e basic equipment required to complete this course is access to a computer with Adobe Photoshop CS3 (CS2 would suffi ce for many of the projects contained in the book) Th e photographic and design industries have traditionally used Apple Macintosh computers but many people now choose ‘Windows’-based PCs as a more cost-eff ective alternative When Photoshop is open there are minor diff erences in the interface, but all of the features and tools are identical It is possible to use this book with either Windows-based or Apple Macintosh computers

Storage

Due to the large fi le sizes involved with digital imaging it is advisable that you have a high-capacity, removable storage device attached to the computer or use a CD or DVD writer to archive your images

Commands

Computer commands which allow the user to modify digital fi les can be accessed via menus and submenus Th e commands used in the study guides are listed as a hierarchy, with the main menu indicated fi rst and the submenu or command second, e.g Main menu > Command or Submenu > Command For example, the command for opening the Image Size dialog box would be indicated as follows: Edit > Image Adjustments > Image Size

Keyboard shortcuts

Many commands that can be accessed via the menus and submenus can also be accessed via keyboard ‘shortcuts’ A shortcut is the action of pressing two or more keys on the keyboard to

carry out a command (rather than clicking a command or option in a menu) Shortcuts speed

up digital image processing enormously and it is worth learning the examples given in the study guides If in doubt use the menu (the shortcut will be indicated next to the command) until you become more familiar with the key combinations

Note > Th e keyboard shortcuts indicate both the Mac and PC equivalents

Example: Th e shortcut for pasting objects and text in most applications uses the key

combination Command/Ctrl + V Th e Macintosh requires the Command key (next to the spacebar) and the V key to be pressed in sequence whilst a PC requires the Control key (Ctrl) and the V key to be pressed

~ Set up the computer, monitor and software preferences for effective digital image editing

~ Gain familiarity with the Photoshop interface

~ Review Photoshop’s basic tools and commands for navigating images on screen

Digital setup

Photoshop is the professional’s choice for digital image editing Photoshop affords precise control over images that are destined to be viewed on screen and in print In order to maximize this control it is necessary to spend some time setting up the software and hardware involved in the imaging process in order to create a predictable and efficient workflow

This chapter will act as a pre-flight checklist so that the user can create the best possible working environment for creative digital image editing The degree

of sophistication that Photoshop offers can appear daunting for the novice digital image-maker, but the time required setting up the software and hardware in the initial stages will pay huge dividends

in the amount of time saved and the quality of the images produced

Commands and shortcuts

This chapter will guide you to select

various options from a list of menus on

your computer If a command or dialog

box is to be found in a submenu, which in

turn is to be found in a main menu, it will

appear as follows: ‘Main menu > Submenu

> Command’ Many of the commands can

be executed by pressing one or more of the

keyboard keys (known as ‘keyboard shortcuts’)

Keyboards: Mac and PC keyboards have different layouts The ‘Alt’ key on a PC is the

‘Option’ key on a Mac The functions assigned to the ‘Control’ key on a PC are assigned

to the ‘Command’ key on a Mac (the key next to the Spacebar with the apple on it) When the text lists a keyboard command such as ‘Ctrl/Command + Spacebar’ the PC user will press the Control key and the Spacebar while the Mac user should press only the Command key together with the Spacebar
