Advance Praise for Enhancing Architectural Drawings and Models with Photoshop

Scott Onstott has a way with Photoshop and CAD—plain and simple. In fact, his ingenious insight is somehow always presented “plain and simple” so that the average user can fully comprehend the techniques he is trying to get across. Scott’s years of teaching come into play here as he masterfully takes the reader from novice to expert as they traverse the pages of this book. His years of CAD experience and insight shine through as he has truly been there—just as the reader is now—and whether you are working in 2D or 3D, Scott has the answers. Scott Onstott’s books are the first ones I pick up when I need to master a new software product—and he never lets me down!

—Lynn Allen, Autodesk Evangelist

This Photoshop book is unique because it specifically focuses on the use of Photoshop by architects, particularly the new 3D capabilities in the last few releases of Photoshop Extended—information that is hard to find elsewhere, even in the Photoshop documentation. It was illuminating and exciting to see what is now possible to do with 3D models in addition to 2D drawings in Photoshop! Scott Onstott brings together his extensive expertise and skills as an architect, technologist, artist, and author in crafting this book, which is written in a clear, concise, and engaging manner and amply supported by numerous illustrations. It starts from the basics of how to prepare a drawing or model within its native application for enhancement in Photoshop and goes on to cover all of the relevant features and functionalities that can be used, including the latest CS5 capabilities such as Content-Aware removal, enhanced selection controls, Puppet Warp, HDR Toning, Mixer Brush, the new Materials library, Repoussé, and image-based lighting. Everything that you want to know about how to use Photoshop for enhancing architectural drawings and models is in this book.

Acknowledgments

I wish to personally thank you for taking the time to learn more about using Photoshop in an architectural context. It will give you great personal satisfaction to master such an amazing program and use it in ever more creative ways. Mastering any software is a difficult task that requires many hours of study and commitment, but learning how to enhance your architectural drawings and models in Photoshop is worth the time and effort. In addition to improving the presentation of your professional materials, knowledge of Photoshop opens to you the opportunity to participate in the vibrant community that has grown up around Photoshop, not just in architecture, but also in many other fields and disciplines.

A team of people has been instrumental in making this book the reality you are holding in your hands or reading on the screen. First, I’d like to thank Chris Main, who is a key figure in the Photoshop universe (managing editor of Photoshop User and former managing editor of Layers) for writing the foreword to this book.

I would also like to express my sincere gratitude to the professional team at Sybex (an imprint of Wiley) for making possible such a technically and linguistically correct, readable, and polished book. It has been a pleasure working with senior acquisitions editor Willem Knibbe and editorial manager Pete Gaughan again, having worked with them both long before Sybex was part of Wiley. I couldn’t be more pleased to have this book published through Wiley, as their team is truly top-notch. Many thanks go to Denise Santoro Lincoln for her superb work as this book’s development editor. Thanks also to my good friend Ian Le Cheminant, who has done a stellar job keeping me on track in his work as technical editor.

About the Author

Scott Onstott has a degree in architecture from UC Berkeley and has worked in several prominent architecture, engineering, and interiors firms in San Francisco. In addition, he has taught AEC software to thousands of students at several Bay Area universities. Scott has written and edited scores of books, magazine articles, and video tutorials, including the video series “Photoshop for Architects.”

Foreword

As the former managing editor of Layers: The How-to Magazine for Everything Adobe (2005–2010) and the current managing editor of Photoshop User, the official magazine of the National Association of Photoshop Professionals (1999–2004, 2010–present), I’ve worked with many talented, incredibly bright writers and educators. So I was honored when Scott Onstott asked me to write the foreword for the book that you’re now holding because I count Scott as one of those top talents whom I’ve had the privilege to work with. His knowledge of Photoshop, architecture, 3D, and digital imaging always amazes me.

Scott is a regular contributor to Photoshop User, and I look forward to editing his column every issue because I know that I’ll always learn something new. Just glancing at Scott’s resume will tell you that he’s extremely knowledgeable and a true master at his craft. The list of books, DVDs, and CDs that he has worked on as technical editor, revisor, compilation editor, contributing author, author, and self-publisher makes me feel like I’ve been standing still for the past 10 years.

Of course, that’s not true, as I’ve edited quite a few Photoshop articles in my time. And that’s the main reason I’m so impressed with Scott’s new book. Even with all the Photoshop knowledge that I’ve accumulated over the years from some of the top graphic artists and trainers in the world, I still walked away from Scott’s book learning an abundance of new Photoshop techniques and tricks. Scott reveals some hidden gems in Photoshop that you would be hard-pressed to find on your own (or even in an entire course on Photoshop). In fact, I’d love to tell you about some of them right here, but I don’t want to steal Scott’s thunder. And best of all, Scott tells you why the many techniques that he shares with you in the book are so important to real-world professionals who use Photoshop every day to create and manipulate amazing architectural drawings, photographic images, and 3D models. You’ll also find a lot of tips and tricks for using digital cameras to capture the images that people in this industry use every day.

And don’t worry if you’re new to Photoshop. Scott clearly guides you every step of the way, and the many practice files he provides on the DVD make it even easier to learn these techniques, keeping you focused on learning Photoshop and not out trying to gather or capture your own image files with which to practice. He even provides multiple versions of the same file as it progresses through a series of tutorials. That way, if you want to skip ahead, you can just open the version of the file that you need—that’s a very nice touch.

As you work your way through this book, you’ll learn a lot about Photoshop. And I mean a lot. To enhance architectural drawings and models in Photoshop, there are many tools and features that you need to know how to use. From smart objects to layer styles to filters to 3D tools to animation and video, you’ll learn it all right here in this book. Even if your main focus isn’t on creating or editing architectural renderings or 3D models, there’s a ton of information that you can easily carry over to other aspects of digital imaging and manipulation.

As with any profession, the more proficient you are with the tools of your trade, the more efficient and productive you’ll be. But the real advantage is that you’ll spend more time being creative and spend less time trying to figure out which is the best tool for the job at hand. This book will be a giant leap forward in making you a more productive and creative professional.

Introduction

This book is for architects, designers, engineers, builders, real estate developers, web designers, students, and anyone who communicates with drawings and 3D building models in their work. Adobe Photoshop can be used for so much more than resizing and printing images; Photoshop is an indispensable tool for enhancing the level of your graphic communication.

The Extended version opens up whole new vistas of creative possibility, including 3D imagery, animation, and video editing capabilities. You’ll need the Extended version for assorted tutorials in Chapters 3, 5, and 8–12.

Each chapter of this book exposes you to concepts and techniques that show you how to integrate Photoshop into your digital workflow in conjunction with other software such as AutoCAD, Revit, 3ds Max, SketchUp, and NASA World Wind. You will find step-by-step tutorials that reveal a wide variety of techniques built on many years of real-world experience. You’ll also learn how to enhance your graphic presentations and gain important marketing benefits for your practice.

This book assumes basic familiarity with Photoshop’s essential concepts. If you are an absolute beginner to Photoshop, I recommend reading the first edition of this book: Enhancing CAD Drawings with Photoshop (Sybex, 2005).

How to Use This Book

The first two chapters of this book are related and should be read in sequence. Chapter 1 is about preparing computer-aided design (CAD) and/or building information models (BIM) for enhancement, and Chapter 2 teaches you how to add the enhancements (such as color, pattern, shadow, and lineweight) in Photoshop.

All of the other 10 chapters are self-contained and organized by subject, so feel free to read them in any order. I recommend flipping through the book’s color section to get an idea of what’s possible. After deciding on what type of imagery you are interested in creating, you can select the relevant chapter and dive right in. Each chapter features tutorials that take you step by step through many complex procedures. The goal of performing these steps on your own is to aim for an understanding that you can abstract into skills you can apply to many different real-world situations.

While every project presents different obstacles and opportunities, I urge you to focus on the concepts and techniques presented, rather than memorizing the specific steps used to achieve the desired result. The best way to build skills is to perform the steps on your computer exactly as they are presented in the book during your first reading. After you achieve the desired result, start over and experiment using the same techniques on your own project (whether invented or real). After you have practiced, think for a moment about how you have achieved the desired result, and try to abstract the steps performed into concepts that you will remember. Only then will you really begin to own the knowledge and get the most out of this book.

What You’ll Find in This Book

Chapter 1, “Preparing Drawings in CAD or BIM for Enhancement,” goes into the complexities of formatting and outputting scaled raster data from the vector world of CAD and BIM programs such as Autodesk AutoCAD, and Revit.

Chapter 2, “Enhancing Drawings in Photoshop,” teaches you the skills to enhance the technical drawings output from Chapter 1 with the power of Photoshop. You’ll add tone, color, pattern, gradient, and shadow to line drawings that pop the presentation up to a new level.

Chapter 3, “Stretching the Photographic Truth,” gives you techniques to stretch the literal truth and shift focus in the visual story you are selling your clients. From removing unwanted objects, to replacing the sky, to adjusting color, to subtly altering content and expanding the dynamic range, you’ll be able to paint the picture you desire.

Chapter 4, “Crafting Interactive Panoramas,” provides detailed steps to help you pick up a number of skills ranging from properly shooting panoramic images and merging them into a composite whole, to blending all the seams and outputting full 360-degree interactive experiences for the Web.

Chapter 5, “Exploring Multiple-Exposure Tricks,” details tricks that become available when you shoot multiple exposures of the same subject. Techniques include removing objects in motion, rendering time-lapse video from a series of stills, artistic processing of video clips, and expanding dynamic range by using exactly two bracketed images.

Chapter 6, “Creating Texture Maps,” shows you how to work with texture maps for use in Photoshop or other 3D programs. You will create textures from scratch, make seamless textures, harvest objects from photos to use as textures, and gain the skills needed to extract people from photos for reuse in your building elevations and perspective projects.

In Chapter 7, “Compositing Imagery from 3D Applications,” you’ll learn the art of compositing, whereby you transfer renderings of various visual components (diffuse, specular, shadow, and so on) from 3ds Max into Photoshop for blending into a final composition. The same process can be adapted to working with other high-end 3D packages. In addition, you’ll learn how to narrow the depth of field in Photoshop to focus the viewer’s attention on an area of interest.

Chapter 8, “Working with Imported 3D Models,” covers the mechanics of working with 3D models inside the Extended version of Photoshop. You will gain the skills necessary to successfully transfer 3D models into Photoshop, navigate in 3D space, adjust materials and maps, illuminate with virtual light, cast shadows, and render the model within Photoshop.

Chapter 9, “Illustrating 3D Models,” offers artistic methods for illustrating 3D models other than photo-realistic rendering. From illustrating with smart filters, to hybrid uses of 3D render settings, to painterly approaches to illustrating models, the artist in you will find expression.

Chapter 10, “Integrating 3D Models with Photos,” blurs the border between photographs and 3D imagery. You’ll learn to integrate 3D models as entourage in architectural interiors, as well as integrate entire buildings into street photos so that the virtual appears to be almost real.

In Chapter 11, “Playing with Depth Perception,” you’ll experiment with depth perception to create richer visualization experiences. Techniques include extruding a logo into a 3D object with Photoshop CS5’s new Repoussé feature, harnessing vanishing point to replace textures in perspective, measuring in perspective, and shifting the entire perspective. In addition, you’ll explore the world of stereographic and anaglyphic imagery that extends the illusion of depth to novel modes of perception.

Chapter 12, “Working with Animation and Video,” opens the door to working with animation and video within Photoshop. Tutorials include animating one frame at a time, animating using the timeline, altering videos the smart way (with smart objects), and finally, animating 3D models in the timeline.

What’s On the Companion DVD

The DVD-ROM that accompanies this book includes all the files you’ll need to use in the tutorials and exercises throughout the chapters. The sample files include native drawing, model, and Photoshop files plus various types of image formats and video files. The companion DVD also contains videos captured off my screen that briefly describe techniques from each chapter.

Free trial versions of Adobe Photoshop CS5 Extended, Autodesk AutoCAD 2011, Google SketchUp 8, and Garden Gnome Software’s Pano2VR (the panoramic utility used in Chapter 4) are also included on the companion DVD.

Chapter 1

Preparing Drawings in CAD or BIM for Enhancement

Communicating design ideas with plans, elevations, and section drawings is second nature to architects, engineers, builders, and designers in related disciplines. Many professionals subconsciously assume that everyone is aware of what is actually an obscure set of graphic conventions surrounding measured drawings. These conventions are either learned in design school or integrated through osmosis early in one’s career.
