Chapter One

System Configuration and 3D in Photoshop CS5

The Adobe Photoshop application works closely with your computer's hardware profile to use its capabilities most efficiently. This smart relationship between Photoshop and the computer hardware ensures a better workflow for your Photoshop project. Many users who do not understand the relation between Photoshop and hardware—especially RAM—may face issues such as a slow workflow or lack of memory. A good understanding of this relation lets you configure Photoshop to meet your requirements on the one hand and your computer's capabilities on the other. In addition to the hardware relationship, you can configure your Photoshop workspace depending on your project needs and on which features in Photoshop you are using the most.

Let's start by helping you discover how to best configure Photoshop for ideal utilization of both hardware and the Photoshop workspace.

Are you a Mac person or a Windows person? We won't fight about which is better, and I am not even going to tell you what my own choice is. Photoshop works fine on both operating systems, so choose whichever best fits your needs. Photoshop deals with both operating systems in the same way, so the only difference that you will notice is changes in shortcuts between keyboards for each operating system.

Note: The main difference between both operating system shortcuts is between two keys on your keyboard. The Command (CMD) key on the Mac is the same as the Control (CTRL) key in Windows, and the Option key on the Mac is the same as the ALT key in Windows. I will mention both shortcuts in tutorials and examples to avoid any confusion.

When I first learned Photoshop, I did not pay any attention to the hardware requirements, because my computer specifications are very robust. But I soon realized that I could get the best performance out of Photoshop by being a little bit smarter.

Actually, Photoshop is too smart when dealing with your hardware, and it works in a different way than other Adobe products do, so you have to really understand what your computer needs to work in the optimum way with Photoshop (especially the 3D features). In the Preferences dialog box, you will see a variety of options to specify how Photoshop deals with your system resources such as memory and storage.

But the following questions remain: What are the resources that you have to take into consideration when installing Photoshop? Which resources can be managed, and which ones require a hardware upgrade? You'll find the answers in this book.

Hardware Resources Utilization

There are resources in your computer to consider regardless of your type of Photoshop project, such as RAM, processing power, and hard drive storage space, and special consideration should be given to the graphics card, which will enable you to handle 3D content and render 3D projects in Photoshop. Along with other features such as Canvas Rotation, Scrubby Zoom, and so on—that is, GPU features, and there are a lot of them—the Painting feature also relies a bit on your graphics card. But before digging more into resources that you need to consider while working with Photoshop and how to optimize it for the best Photoshop 3D performance possible, I will mention the general system requirement to install Photoshop for both Mac and Windows.

Processor

Although Photoshop does not require a multiprocessor computer, having one will help many of Photoshop tools, filters, and 3D features work much faster than they do on a single-processor computer.

RAM

One of the resources that Photoshop loves and that affects your work in the application is the amount of RAM (random-access memory) on your machine. Although the recommended RAM to run Photoshop is 1 GB for both Windows and Mac, the amount of RAM necessary when working with Photoshop depends on your project. Photoshop's RAM usage heavily depends on the size of the files that you open in Photoshop, because each file you open in Photoshop uses RAM equal to about four times its size.

The more RAM your system is fueled by, the larger the files you will be able to handle in Photoshop. For example, if you are working with website images and images in low resolution, you will not feel that much pain when working with only a little RAM memory. But if you are working with files that must be printed, or 3D content or animation files with a lot of layers, you will definitely need a lot of RAM to be able to work easily.

The current Windows version, Vista, can load a maximum of 4 GB RAM, and Mac OS X can hold up to 8 GB RAM. So I always recommend buying as much RAM as you can afford, because RAM is the thin line between working in joy or pain in Photoshop.

Photoshop is a really smart application when dealing with memory: when you open Photoshop, it loads some of its files into the RAM, such as the fonts, presets, and others. Then it starts to use parts of the RAM for opening and working on your files. After using up the allocated RAM amount for Photoshop, it starts to take from the scratch disk. The scratch disk is a part of the hard disk that Photoshop uses as a virtual memory when it reaches the limit of the allocated files in the RAM. Let's focus on the RAM memory now, and dig deeper into the topic of scratch disk memory after.

Because it is smart, Photoshop enables you to customize how it deals with RAM and to set a limit for it to use from the memory and memory allocation; these settings are located in this Photoshop Preferences dialog box. I remember a very funny mistake of mine when I was learning Photoshop. I allocated all the memory to Photoshop—which left nothing for my operating system and other applications! Actually, it is a common mistake, but it will kill your computer, and you will never be able to work with other products properly, so be careful when setting the memory usage limit.

The default Photoshop RAM memory allocation depends on your operating system and the amount of RAM you have in your machine. Also, it depends on whether you run a 32-bit or 64-bit operating system. For example, if you are running Mac OS 10.4.11 or later, Photoshop will use up to 3.5 GB of the available RAM. In Windows, the Photoshop 32-bit version can use up to 1.7 GB in the 32-bit Windows version and 3.2 GB in 64-bit Windows, and the Photoshop 64-bit version, which runs only on 64-bit Windows, can get as much as your computer can afford. And Photoshop is supported by Windows PX with Service Pack 3, Windows Vista with Service Pack 1 or 2, and Windows 7.

The Photoshop performance settings are controlled through the Performance section in the Preference dialog box. You can find the Preferences dialog box via the menus Photoshop > Preferences (Mac OS) and Edit > Preferences (Windows). However, the Preference dialog box includes a separate section for the 3D settings, which provides full control over the 3D options in Photoshop. The 3D section lets you assign virtual RAM (VRAM) for the 3D projects. Also, you can set the properties of the Open GL, 3D resources guides colors, 3D ground plane, Ray Tracer options, and the loading 3D files option.

In the Performance dialog box, notice that Photoshop shows the available RAM that you can assign to Photoshop and the ideal range of RAM that Photoshop can use. You can set the RAM allocated to Photoshop using the input text box, or move the slider to the left or right or click the plus icon in the right of the slide bar or the minus icon in the right of the slide bar.

Scratch Disks

Another clever method to handle computer resources to get the most out of Photoshop performance process is the scratch disk, as mentioned previously. The scratch disk is actually virtual memory—Photoshop takes part of your hard disk and uses it as virtual memory to maximize the amount of memory to handle files and tools, especially large files and memory-intensive Photoshop features, such as some of the filter and 3D tools. When your system is out of RAM allocated for Photoshop, it starts to use the assigned space on the hard disk as memory.

Photoshop requires 2 GB of hard disk space, but it appreciates more space for better performance and the ability to handle larger files. Therefore, the selected hard disk or disk volume that Photoshop will rely on as virtual memory should have plenty of space.

Because the memory is used to save your current work in Photoshop, it should be fast and able to handle Photoshop processes. This guideline applies to the scratch disk as well, so the scratch disk you rely on as virtual memory should be fast, well-defragged, and separate from the primary operating system disk or volume that is used for the operating system's virtual memory and paging. External hard disks and network hard disks are not recommended, because they will not be as fast as virtual memory.

Photoshop allows you to specify the volume that will be used as a scratch disk, with a total maximum space of 64 exabytes (1 exabyte equals 64 billion gigabytes). In the Performance dialog box, choose which volume to use as the scratch disk and arrange the volumes in order of your preferred usage sequence.

In the Scratch Disk preferences section, Photoshop lists the volumes that can be used as scratch disks. Check the box next to the volume that you would like to use as a scratch disk. You can change the order of the scratch disks by moving the selected Scratch Disk up and down in the list.

"Out of RAM" Errors

Because we are going to work with tools that consume a lot of operating system resources, especially virtual memory, you should know about an error message that may occur when you try to use a tool or a filter when its memory requirements exceed the available memory limit. Memory is consumed by other operations, tools, and filters that you use while working in your project, and at some point you may run out of free memory to execute the next process.

The solution to solve this problem is to free up some memory by closing the unwanted files and clear your history or limit the saved history steps. One of the most helpful things to do in order to free up Photoshop memory and therefore speed up your work is to purge the clipboard, undo list, and histories. Selecting Edit > Purge clears the various steps that Photoshop saves in memory, such as clipboard items, undo and history steps; this frees memory, which speeds up your work and gives you the ability to work with additional tools and filters—especially the memory-consuming tools.

When you open Purge from the Edit menu, you will have the option to delete the clipboard, the undo steps, the history steps, or all of them together. Keep in mind, however, that this will limit your ability to go back in your history to undo you work. You may want to save a copy of your working file at a particular state before you purge your history, just to be sure that you could get back to that version of the file if necessary.

As we're talking about memory and disk space, here are some facts about the file size and dimension limitations in Photoshop. The maximum file size for the PSD document is 2 GB, the TIFF maximum file size is 4 GB, and the maximum file size for the PDF document is 10 GB. When the PSD files cannot store large data files, you can save it using the PSB file format.

The file dimension limitations are 300,000×300,000 pixels for native PSD files and 30,000×30,000 pixels and 200×200 inches for PDF files. Keep in mind that large files may cause problems if you try to open them in an older version of Photoshop, such as version 7.

Getting the Most Out of the Photoshop Workspace

As I mentioned before, Photoshop is widely used in various types of tasks and professions, which means that it includes many panels, menus, and features to cover each field of interest's needs and requirements. Thus, some Photoshop users use specific panels or features more than others, depending on what they need to do and the nature of their Photoshop projects.

In old Photoshop versions, I was forced to keep many panels open and suffered as all these panels covered the actual work. The only working solution was to keep moving the panels around to reveal the design file under it. Another option was to open the panels when I needed them and then close them again, and to keep doing this every time I needed the panel. This approach was frustrating and time-consuming, especially with a large Photoshop project with many tasks.

Also, opening all the panels at the same time may be confusing and take up a lot of space, because some panels are used more than others or may not be used at all, even after implementing the docking panels layout. For example, if you are a photographer, you will need the panels that can help you edit photos and manage colors more than you will need panels like the 3D or animation panels.

The solution is to use the Photoshop workspace options to set the Photoshop panels' layout to meet your needs or even to create your personal favorite arrangement for the workspace. This makes life so much easier! In Photoshop, you can either choose from the default workspace options or create your own workspace and save it for further use. One of the new features in the Photoshop CS5 is the new appearance of the workspace option at the top right of the Photoshop working environment.

The workspaces that already exist when you first install it are:

• Essentials: This workspace option displays some of the essential panels that are commonly used by most of us, such as the Layers panel, Color panels, and Adjustments panel.

• Design: This workspace option shows the design-related panels, such as the Swatches panel, Styles panel, History panel, Character and Layer panel.

• Painting: This option activates the Brush and Color panels that are important when using Photoshop as a painting application, especially when using the new brushes and enhanced painting techniques.

• Photography: This option prepares the workspace for photographers who would like to edit photos in Photoshop. However, panels such as Histogram and Adjustments are activated in this mode.

• 3D: The 3D workspace activates the 3D panel, which is frequently used to edit the 3D scene or models. Also, the Layers panel becomes active so you can use it to navigate between 2D and 3D layers.

• Motion: This option sets the workspace to be ready for animation and video projects, which mainly activates one panel that allows you to animate both 2D and 3D objects: the Animation panel.

• New in CS5, this workspace displays the new features and panels in Photoshop CS5, such as the Mini Bridge, new brushes, 3D enhancements, Access CS Live, news, and the CS Review panel.

Create Your Own Workspace

You still have the option to create your own custom workspace to suit your project needs and display the panels used in your project. By default, not all the panels are displayed when you first install Photoshop. So you can choose from the workspace presets or create your own workspace. To display a panel, select it from the Window menu; you can arrange the panels in the workspace at either the right, left, or bottom of the workspace.

If you would like to keep some panels floating, no problem: just undock the panel by dragging it anywhere in the middle of the workspace, so you can keep the panel floating without putting it in a fixed place, in case you like to move the panel while working.

To change the position of the panel, click the panel header and drag it to any of the workspace edges mentioned previously. Photoshop guides you to the places that allow panel placement by showing a blue highlight line at the places between panels to add the new panel or a blue highlight around the panel to group the new panel within existing panel groups (Figure 1.4). When you group a panel with other panel groups, it appears as a tab in the panel group.

The docking panels give you more space, but this may not be enough, so you still can free some more space by collapsing panels into icons. When you click on these icons, the panel appears. To collapse a panel, click the top right arrow, and then click the arrow again to expand it. When you need to collapse the whole panel sidebar, click the topmost right arrow and the whole panel will be displayed as icons, with the name of each panel next to it.

Move your mouse cursor over the sidebar's left edge, and it will turn to a double-sided arrow to indicate that you can resize the collapsed panel to hide the panels' names and show only the icons.

Save Workspace

After you've rearranged the panels and created your own Photoshop workspace, it is time to save this workspace and add it to the workspace list. To save the workspace, follow these steps:

1. Open the New Workspace dialog box via Window > Workspace.

2. In New Workspace dialog box, give your new workspace a name.

3. In the Capture area, you can opt to save the keyboard shortcuts and the menus modifications as well.

4. Click OK to save this customized workspace.

Delete Workspace

Adobe Photoshop allows you to delete the custom workspace. To delete a workspace, follow these steps:

1. Make sure that you are not currently using the workspace you would like to delete.

2. Select Window > Workspace > Delete Workspace.

3. Choose the Workspace you would like to delete from the drop-down menu and click OK.

    Two Digitally Animated Thumbs Up

    I've been using Adobe Creative Suite programs for the better part of a decade now, so needless to say I've also read a number of instructional guides to learn how to utilize these programs to the best of their potential. Because, let's face it, teaching yourself or trying to learn through the Help menu just doesn't cut it when you need to achieve and maintain a high level of proficiency in many complex design programs (as so many of us have found out the hard way).

    It's the maintaining of that proficiency that can be the most difficult, but also the most rewarding, keeping your skills on the cutting edge, learning innovative ways to use programs. So that's where this book comes in. Many animators don't even know that Photoshop has 3D animation capabilities, and it is an admittedly new function. You will also find that it is an indispensable one, but only after you learn how to harness its power, both with new knowledge, and also the knowledge you probably already have about using Photoshop.

    And there in lies the true beauty of this text, Photoshop 3D for Animators. The more you can get done within one program, the better. It saves SO much time! Both in terms of not having to switch between programs or reformat, but also saves time in terms of training. We all know how daunting a task it is to learn a new program, even to just reach a fairly good useable knowledge of it, let alone reaching a high level of expertise. This text helps to amplify a basic knowledge of Adobe Photoshop for 2D design quickly into a working knowledge and expertise in the lesser-known 3D capabilities, all within THE SAME PROGRAM. It's really exciting stuff. Or it was for me, anyway.

    For me to go into too much technical detail here is not really of much use. But I will say that the book takes you through even the most minute considerations, such as the best computer and program configurations, the small differences between Mac and Windows Photoshop shortcuts, and a variety of other things you probably wouldn't have thought of but can make a big difference. And at the same time, this book demonstrates in an easy to understand, step by step explanation, what you need to know to get you up to speed for using Photoshop as a 3D animator, doing everything your old software did and more, and more easily.

    Also, lets not forget another beauty of using Photoshop for your 3D animation work: the ease of integration between other Creative Suite applications, such as Flash and After Effects. This book makes this integration even easier, as well as most efficient. I mean, if you're going to shell of the big bucks it costs for Adobe Creative Suite, why no use it to its fullest? It's just silly not to.

    This is all not to mention the book's highly intuitive layout. Just as you think you have a question, it is answered immediately. Very well laid out and aesthetically pleasing format. This book is an absolute must-have for 3D animators, newbies and experts alike, who are using or thinking of using Photoshop for their 3D work. It really just makes sense. I've never looked back.
